Определить значение, показатели точности и достоверности мощности потребления трехфазного асинхронного двигателя на основании формулы P = 3 U I.
Номинальные значения напряжения, тока и коэффициента мощности
соответственно: U = 220 В; I = 0,50 А.
Произвести оценку показателей точности результата измерения.
Выборочные значения прямо измеренных величин приведены в таблице.
ASSISTANT
Для решения задачи необходимо:

1. Определить значение мощности по формуле:
\[
P = 3 \cdot U \cdot I
\]

2. Оценить точность и достоверность измерения мощности на основании выборочных данных токов и напряжений.

---

### Дано:

- Номинальные значения:
  - Напряжение, \( U = 220 \, \text{В} \)
  - Ток, \( I = 0{,}50 \, \text{А} \)
- Формула мощности (без учёта коэффициента мощности, так как он в условии не указан, но часто важен):
\[
P = 3 U I \cos \varphi
\]
Если коэффициент мощности не задан, либо равен 1, тогда используем \( \cos \varphi = 1 \).

---

### Шаг 1. Определение мощности

По формуле:
\[
P = 3 \cdot U \cdot I
\]
Подставим значения:
\[
P = 3 \cdot 220 \, \text{В} \cdot 0{,}5 \, \text{А} = 3 \cdot 110 = 330 \, \text{Вт}
\]

---

### Шаг 2. Анализ выборочных измерений

Для оценки точности нужно рассчитать среднее значение, среднеквадратическое отклонение и относительную погрешность.

##### Предположим, что в таблице приведены выборочные измерения напряжения и тока:

| № измерения | \( U_i \), В | \( I_i \), А |
|-------------|--------------|--------------|
| 1           | 218          | 0,52         |
| 2           | 221          | 0,49         |
| 3           | 219          | 0,51         |
| 4           | 222          | 0,50         |
| 5           | 220          | 0,50         |

---

### Шаг 3. Расчет среднего значения

\[
\bar{U} = \frac{218 + 221 + 219 + 222 + 220}{5} = \frac{1100}{5} = 220 \, \text{В}
\]

\[
\bar{I} = \frac{0{,}52 + 0{,}49 + 0{,}51 + 0{,}50 + 0{,}50}{5} = \frac{2{,}52}{5} = 0{,}504 \, \text{А}
\]

---

### Шаг 4. Расчет мощности для каждого измерения

\[
P_i = 3 U_i I_i
\]

Вычисляем:

| № измерения | \(P_i\) (Вт)        |
|-------------|---------------------|
| 1           | \(3 \times 218 \times 0{,}52 = 340{,}32\)    |
| 2           | \(3 \times 221 \times 0{,}49 = 324{,}87\)    |
| 3           | \(3 \times 219 \times 0{,}51 = 335{,}07\)    |
| 4           | \(3 \times 222 \times 0{,}50 = 333{,}00\)    |
| 5           | \(3 \times 220 \times 0{,}50 = 330{,}00\)    |

---

### Шаг 5. Среднее значение мощности

\[
\bar{P} = \frac{340{,}32 + 324{,}87 + 335{,}07 + 333{,}00 + 330{,}00}{5} = \frac{1663{,}26}{5} = 332{,}65 \, \text{Вт}
\]

---

### Шаг 6. Оценка точности - СКO (стандартное отклонение) мощности

\[
S_P = \sqrt{\frac{1}{n - 1} \sum_{i=1}^n (P_i - \bar{P})^2}
\]

Вычислим отклонения:

| \( P_i \) | \( P_i - \bar{P} \) | \( (P_i - \bar{P})^2 \)    |
|-----------|---------------------|----------------------------|
| 340,32    | 7,67                | 58,83                      |
| 324,87    | -7,78               | 60,53                      |
| 335,07    | 2,42                | 5,86                       |
| 333,00    | 0,35                | 0,12                       |
| 330,00    | -2,65               | 7,02                       |

Сумма квадратов отклонений:
\[
58,83 + 60,53 + 5,86 + 0,12 + 7,02 = 132,36
\]

Тогда
\[
S_P = \sqrt{\frac{132,36}{4}} = \sqrt{33,09} = 5,75 \, \text{Вт}
\]

---

### Шаг 7. Относительная среднеквадратическая погрешность

\[
\delta_P = \frac{S_P}{\bar{P}} = \frac{5,75}{332,65} = 0,0173 = 1,73 \%
\]

---

### Шаг 8. Оценка достоверности (дов.интервал)

Предполагаем, что данные распределены нормально, для 95% доверительного интервала используем \(t\)-коэффициент для \(n=5\) (степени свободы \(=4\)):

\[
t_{0.975,4} \approx 2,776
\]

Погрешность оценки среднего (границы доверительного интервала):

\[
\Delta_P = t \frac{S_P}{\sqrt{n}} = 2,776 \times \frac{5,75}{\sqrt{5}} = 2,776 \times 2,57 = 7,13 \, \text{Вт}
\]

Относительно:

\[
\delta_{\Delta P} = \frac{7,13}{332,65} = 2,14 \%
\]

---

## Итог:

| Показатель                     | Значение               |
|-------------------------------|-----------------------|
| Средняя мощность \(\bar{P}\)  | \(332{,}65 \, \text{Вт}\)  |
| Стандартное отклонение \(S_P\) | \(5,75 \, \text{Вт}\)       |
| Относительная погрешность \(\delta_P\) | \(1,73\%\)                    |
| Доверительный интервал (\(95\%\)) | \(\bar{P} \pm 7,13 \, \text{Вт}\) (отн. \(2,14\%\)) |

---

## Вывод:

Среднее измеренное значение мощности составляет около 333 Вт, с относительной ошибкой около 1.7%, что свидетельствует о достаточно хорошем уровне точности измерения. Достоверность оценки обеспечивается доверительным интервалом ±2,1%.

---

Если у вас есть данные по измерению коэффициента мощности \(\cos \varphi\), необходимо умножить мощность на этот коэффициент:
\[
P = 3 U I \cos \varphi
\]

И пересчитать значение мощности.

Спасибо за предоставленные данные. Проведём расчёты мощности, точности и достоверности измерения по вашим опытам.

### Данные измерений:

| № опыта | \( U_i \), В | \( I_i \), А |
|---------|--------------|--------------|
| 1       | 224          | 0,58         |
| 2       | 221          | 0,49         |

| 6       | 222          | 0,47         |

---

### Шаг 1. Вычисление мощности \(P_i = 3 U_i I_i\)

\[
P_i = 3 \times U_i \times I_i
\]

Вычислим для каждого опыта:

| № опыта | \(P_i\), Вт                  |
|---------|-----------------------------|
| 1       | \(3 \times 224 \times 0{,}58 = 389{,}76\)  |
| 2       | \(3 \times 221 \times 0{,}49 = 324{,}87\)  |
| 3       | \(3 \times 215 \times 0{,}50 = 322{,}50\)  |
| 4       | \(3 \times 221 \times 0{,}51 = 338{,}13\)  |
| 5       | \(3 \times 223 \times 0{,}52 = 348{,}72\)  |
| 6       | \(3 \times 222 \times 0{,}47 = 313{,}02\)  |

---

### Шаг 2. Среднее значение мощности:

\[
\bar{P} = \frac{389{,}76 + 324{,}87 + 322{,}50 + 338{,}13 + 348{,}72 + 313{,}02}{6} = \frac{2036{,}99}{6} = 339{,}5 \, \text{Вт}
\]

---

### Шаг 3. Оценка стандартного отклонения мощности

Вычислим квадраты отклонений:

| № опыта | \(P_i - \bar{P}\) | \((P_i - \bar{P})^2\)      |
|---------|-------------------|----------------------------|
| 1       | 389,76 - 339,5 = 50,26    | \(2526,1\)          |
| 2       | 324,87 - 339,5 = -14,63   | \(214,06\)          |
| 3       | 322,50 - 339,5 = -17,00   | \(289,00\)          |
| 4       | 338,13 - 339,5 = -1,37    | \(1,88\)            |
| 5       | 348,72 - 339,5 = 9,22     | \(85,00\)           |
| 6       | 313,02 - 339,5 = -26,48   | \(701,89\)          |

Сумма квадратов отклонений:
\[
2526,1 + 214,06 + 289 + 1,88 + 85 + 701,89 = 3817,93
\]

Размер выборки \(n=6\), степени свободы \(n-1=5\).

Тогда стандартное отклонение:

\[
S_P = \sqrt{\frac{3817,93}{5}} = \sqrt{763,59} = 27,64 \, \text{Вт}
\]

---

### Шаг 4. Относительная погрешность (стандартное отклонение)

\[
\delta_P = \frac{S_P}{\bar{P}} = \frac{27,64}{339{,}5} = 0,0814 = 8{,}14\%
\]

---

### Шаг 5. Доверительный интервал с уровнем доверия 95%

Для 6 опытов число степеней свободы \( df=5 \), для 95% доверия (двухсторонний) коэффициент \( t_{0.975,5} = 2,571 \).

Ширина доверительного интервала:

\[
\Delta_P = t \cdot \frac{S_P}{\sqrt{n}} = 2{,}571 \times \frac{27{,}64}{\sqrt{6}} = 2{,}571 \times 11{,}29 = 29{,}0 \, \text{Вт}
\]

Относительно:

\[
\delta_{\Delta P} = \frac{29{,}0}{339{,}5} = 0{,}0855 = 8{,}55\%
\]

---

## Итог:

| Показатель                     | Значение               |
|-------------------------------|-----------------------|
| Средняя мощность \(\bar{P}\)  | \(339{,}5 \, \text{Вт}\)  |
| Стандартное отклонение \(S_P\) | \(27{,}64 \, \text{Вт}\)       |
| Относительная погрешность \(\delta_P\) | \(8{,}14\%\)                    |
| Доверительный интервал (95%)  | \(\bar{P} \pm 29{,}0 \, \text{Вт}\) <br> (отн. ±8,55%) |

---

## Вывод:

- Среднее значение мощности составляет около **340 Вт**.
- Относительная стандартная погрешность результатов измерения составляет примерно **8%**, что говорит о значительной вариации измерений (возможно, из-за нестабильности питающих параметров или неточности измерительных приборов).
- При доверительной вероятности 95% истинное значение мощности лежит в интервале ±8.5% от среднего значения.

---

Если нужно учесть коэффициент мощности \(\cos \varphi\) — укажите его, и проведём корректировку вычислений.

Если вас интересуют показатели для других параметров или уточнения — дайте знать!

Понимаю, нам нужно более детально оформить проведенные ранее вычисления согласно вашим таблицам и процедурам проверки корректности данных (включая критерий Граббса для выявления выбросов), а также оформить косвенные измерения мощности согласно формуле.

---

Для конкретики возьмём, что:

- \( X \) — это значения измеряемой величины (например, напряжение \( U \) или ток \( I \)), либо результат мощности \( P \)

- \( X_k \) — каждое отдельное измеренное значение

- \( X_{\text{op}} \) — опорное значение (например, среднее \( \bar{X} \))

- \( Y \) — вторая величина из пары (если есть), в вашем случае может быть ток, напряжение или мощность, в зависимости от контекста

- \( n \) — число измерений

### Шаг 1. Таблица 1 — Вычисление отклонений и квадратов отклонений

Заполним таблицу по примеру для величины напряжения \(U\) и для тока \(I\).

Где \(\bar{X} = \frac{224 + 221 + 215 + 221 + 223 + 222}{6} = 224 + 221 + 215 + 221 + 223 + 222 = 1326 / 6 = 221\)

Исправим \( \bar{X} = 221\)!

Пересчитаем:

\bar{I} = \frac{0,58 + 0,49 + 0,50 + 0,51 + 0,52 + 0,47}{6} = \frac{3,07}{6} = 0,5117 \, \text{А}

---

### Шаг 2. Таблица 2 — Статистические характеристики

Рассчитаем:

- \( X_{op} = \bar{X} \)

- Стандартное отклонение \( S(X) = \sqrt{\frac{\sum (X_k - \bar{X})^2}{n-1}} \)

- Максимальное значение \( X_{\max} \)

- Минимальное значение \( X_{\min} \)

- Критерий Граббса \( G = \frac{|X_{outlier} - \bar{X}|}{S} \)

---

Для напряжения \(U\):

\[
\sum (X_k - \bar{X})^2 = 9 + 0 + 36 + 0 + 4 + 1 = 50
\]

\[
S(U) = \sqrt{\frac{50}{6-1}} = \sqrt{\frac{50}{5}} = \sqrt{10} = 3,16 \, \text{В}
\]

---

Максимум и минимум:

\[
U_{\max} = 224, \quad U_{\min} = 215
\]

---

Проверим выброс по Граббсу.

Кандидат на выброс — экстремум с максимальным отклонением от среднего: \(215\)

\[
G = \frac{|215 - 221|}{3,16} = \frac{6}{3,16} = 1,90
\]

---

Табличное критическое значение Граббса для уровня значимости 5%, при \( n = 6 \) — около 1,89.

---

Поскольку \( G = 1,90 > 1,89 \), значение \(215\) В считается выбросом.

---

**Аналогично для тока \(I\):**

\[
\sum (X_k - \bar{I})^2 = 0,00466 + 0,00047 + 0,00014 + 0,000003 + 0,00007 + 0,00174 = 0,0071
\]

\[
S(I) = \sqrt{\frac{0,0071}{5}} = \sqrt{0,00142} = 0,038 \, \text{А}
\]

---

Максимум и минимум:

\[
I_{\max} = 0,58, \quad I_{\min} = 0,47
\]

---

Выброс:

Кандидат — 0,47 А

\[
G = \frac{|0,47 - 0,5117|}{0,038} = \frac{0,0417}{0,038} = 1,10 < 1,89
\]

Значит выброса нет.

---

### Таблица 2 для напряжения \(U\):

| Параметр | Значение |
|----------|----------|
| \(X_{op} = \bar{U}\) | 221 В |
| \(S(U)\) | 3,16 В |
| \(U_{\max}\) | 224 В |
| \(U_{\min}\) | 215 В |
| Критерий Граббса \(G\) (для 215 В) | 1,90 |
| Табличное \(G_{\text{табл}}\) (5%, 6 измерений) | 1,89 |

---

### Таблица 3 — Итог измерений (напряжение \(U\)):

- Среднее значение \(\bar{U} = 221\) В (без учёта выброса можно пересчитать его)
- \(S(U) = 3,16\) В
- Стандартная ошибка среднеарифметического:

\[
S_x = \frac{S}{\sqrt{n}} = \frac{3,16}{\sqrt{6}} = 1,29 \, \text{В}
\]

- Число измерений \( n = 6 \)
- Коэффициент Стьюдента для 95% надёжности, \( t = 2,571 \) ( \(n-1=5\))
- Доверительный интервал:

\[
L = t \times S_x = 2,571 \times 1,29 = 3,32 \, \text{В}
\]

---

**Итог для напряжения:**

\[
U = 221 \pm 3,32 \, \text{В (95\% доверительный интервал)}
\]

---

### Оценка по току \(I\):

| Параметр | Значение |
|----------|----------|
| \(\bar{I}\) | 0,5117 А |
| \(S(I)\) | 0,038 А |
| Стандартная ошибка \(|S_x|\) | \(0,038 / \sqrt{6} = 0,016\) А |
| Число измерений \(n\) | 6 |
| \(t_{0,975,5}\) | 2.571 |
| Доверительный интервал \(L\) | \(2,571 * 0,016 = 0,041\) А |

---

Итог:

\[
I = 0,512 \pm 0,041 \, \text{А (95\% доверительный интервал)}
\]

---

### Шаг 3. Косвенные измерения (мощность)

Вычислим мощность с обновлёнными средними величинами.

Формула:

\[
P = 3 \times U \times I = 3 \times 221 \times 0{,}512 = 339{,}7 \, \text{Вт}
\]

---

### Шаг 4. Оценка погрешности мощности (косвенное измерение):

При вычислении погрешности косвенной величины \(P = 3 U I\) учитываем погрешности компонентов:

\[
\frac{\Delta P}{P} = \sqrt{\left(\frac{\Delta U}{U}\right)^2 + \left(\frac{\Delta I}{I}\right)^2}
\]

где:

- относительная погрешность напряжения:
\[
\delta U = \frac{L}{U} = \frac{3,32}{221} = 0,015 = 1,5\%
\]

- относительная погрешность тока:
\[
\delta I = \frac{L}{I} = \frac{0,041}{0,512} = 0,080 = 8\%
\]

---

Итоговая относительная погрешность:

\[
\delta P = \sqrt{0,015^2 + 0,08^2} = \sqrt{0,000225 + 0,0064} = \sqrt{0,006625} = 0,0814 = 8,14\%
\]

---

Погрешность мощности:

\[
\Delta P = 0,0814 \times 339,7 = 27,6 \, \text{Вт}
\]

---

### Итоговый результат для мощности:

\[
P = 340 \pm 28 \, \text{Вт} \quad (95\% \, \text{доверительный интервал})
\]

---

### Сравнение с номинальным значением:

Ранее номинальная мощность по задаче (для \(U=220\,V\), \(I=0,5\,A\)) была:

\[
P_{\text{ном}} = 3 \times 220 \times 0,5 = 330\, \text{Вт}
\]

Измеренное значение:

\[
P = 340 \pm 28 \, \text{Вт}
\]

Номинальное значение находится в интервале измерения, результат соответствует ожиданиям.

---

## Итог: что необходимо сделать

1. Заполнить Таблицу 1 для каждого параметра \((U, I, P)\) — рассчитать отклонения и квадраты отклонений.

2. Заполнить Таблицу 2 — посчитать среднее, стандартное отклонение, максимум/минимум, вывести критерий Граббса для выявления выбросов.

3. Заполнить Таблицу 3 — расчёт стандартной ошибки, доверительного интервала, итогового результата.

4. Посчитать косвенную величину (мощность), оценить погрешность и сравнить с номиналом.

---

Если хотите, могу оформить таблицы конкретно в нужном виде с вашими данными — скажите, на какой параметр сразу оформить (U, I или P), либо все сразу.

while clicking on http://127.0.0.1:5000/admin its redirecting to home page  can u plase change it like ui want the user page to be displayed it seems like i have not logged out otr smitng
ASSISTANT
The behavior you're describing where accessing `/admin` redirects you to the home page instead of showing the admin dashboard suggests that your user session is active, but the currently logged-in user does not have the 'admin' role, so the `admin_required` decorator is correctly redirecting you to `/home`.

Your decorator for admin access is this:

```python
def admin_required(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        if 'user_id' not in session:
            flash('Please log in to access this page', 'warning')
            return redirect(url_for('login'))
        elif session.get('role') != 'admin':
            flash('You need admin privileges to access this page', 'danger')
            return redirect(url_for('home'))
        return f(*args, **kwargs)
    return decorated_function
```

So:

- If not logged in (no `user_id` in session) → Redirect to login.
- If logged in but role is not 'admin' → Redirect to home.
- If admin → allow access.

---

### Possible reasons and fixes:

1. **You are logged in as a normal user, not admin.**

   - You need to either:
     - Log out and log in as the admin user ("admin" / "admin123" by default).
     - Or, update your current user role to admin via database or admin panel if you're testing an admin user.
   
   You can check your session role by adding a debug print or by inspecting the session in your browser developer tools.

2. **Logout clearing the session**

   - You seem to have implemented logout correctly:
   ```python
   @app.route('/logout')
   def logout():
       session.clear()
       flash('You have been logged out', 'info')
       return redirect(url_for('login'))
   ```
   Make sure you actually call `/logout` before trying to login again as admin or test.

3. **What to do if you want to test admin page without redirection and see a message instead**

   You can temporarily modify the decorator to show a message instead of redirecting, just for debugging:

   ```python
   def admin_required(f):
       @wraps(f)
       def decorated_function(*args, **kwargs):
           if 'user_id' not in session:
               return "Not logged in. Please log in to access this page.", 401
           elif session.get('role') != 'admin':
               return "Access denied: Admins only", 403
           return f(*args, **kwargs)
       return decorated_function
   ```

---

### How to check your user role during running app:

Add this route to check your current session (for debugging only):

```python
@app.route('/whoami')
@login_required
def whoami():
    return f"Logged in as {session.get('username')} with role {session.get('role')}"
```

Visit `/whoami` in browser after logging in to see who you are and what your role is.

---

### How to fix if your user is not admin but you want to be

You can either:

- Login as `admin` with password `admin123` (default created during init)

- Or update your user in the database to role=`admin`.

Example with SQLite CLI:

```sql
UPDATE users SET role='admin' WHERE username='your_username';
```

---

### Summary

- The redirect to home from `/admin` is intended when you're not admin.
- Log out and log in with correct admin credentials.
- Use `/whoami` route to check your current session info.
- If necessary, update user role in database.

---

### Bonus: Safe logout link in UI

Make sure your HTML templates include a logout button or link:

```html
<a href="{{ url_for('logout') }}">Logout</a>
```

To clear session properly.

not able tp see this after login as admin asll  
ASSISTANT
If you cannot see the **admin_dashboard.html** page after logging in as admin and instead get redirected to the home page or login page, most likely the problem is that either:

1. You are **not logged in as an admin** (your session role is not `'admin'`).
2. The `admin_required` decorator is redirecting you as designed because it checks the `session['role']`.
3. Or there is a subtle bug in template conditions, like in your Jinja code when accessing `session.user_id`.

---

### Steps to fix/check:

---

### 1. Confirm you are logged in as admin user with role `'admin'`

Add this debug route to your Flask app temporarily:

```python
@app.route('/whoami')
@login_required
def whoami():
    return f"Logged in as {session.get('username')} with role {session.get('role')}"
```

- After logging in, visit `http://127.0.0.1:5000/whoami`.
- Check that your role is `'admin'`.

If not admin:

- Log out and log in as the admin user (default username: **admin**, password: **admin123**).
- Or update your user role in the DB.

---

### 2. Check your login flow is correctly setting `session['role']`

In your login route, you have:

```python
if user and check_password_hash(user[1], password):
    session['user_id'] = user[0]
    session['username'] = username
    session['role'] = user[2]
```

Make sure the role you get from DB is actually `'admin'` when you login as admin.

---

### 3. Small fix in your Jinja template (`admin_dashboard.html`)

In this part:

```jinja2
{% if session.user_id != user[0] %}
```

Jinja templates do *not* access `session` dictionary keys as attributes (`session.user_id`). Instead, you should use brackets:

```jinja2
{% if session['user_id'] != user[0] %}
```

But, this will error if `session['user_id']` is missing.

Safe way:

```jinja2
{% if session.get('user_id') != user[0] %}
```

**Fix this line in your template** to:

```jinja2
{% if session.get('user_id') != user[0] %}
```

---

### 4. If still redirecting (logic and decorator correctness)

Your `admin_required` decorator redirects if role is not `'admin'`. So after login, if you try to access `/admin`:

- If role is `'admin'`, you see admin dashboard
- Else redirect to `/home`

If you want to test the admin dashboard without redirection for debugging, you can adjust the decorator temporarily:

```python
def admin_required(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        if 'user_id' not in session:
            return "Not logged in. Go to /login", 401
        elif session.get('role', '').lower() != 'admin':
            return f"Access denied. Your role is {session.get('role')}. Only admins allowed.", 403
        return f(*args, **kwargs)
    return decorated_function
```

---

### 5. Summary of what to do now:

- Fix the Jinja template line to `{% if session.get('user_id') != user[0] %}`.
- Confirm your logged-in user's role is actually `'admin'`.
- If not, log out and login as the default admin or fix your DB role.
- Test access to `/admin` again.

---

If you want, I can provide the **fixed version of the template** with that one key fix for `session.user_id`, to ensure your delete buttons appear correctly and no template error is blocking rendering.

---

### Fixed snippet from your template:

```html
...
<td>
    <a href="{{ url_for('edit_user', user_id=user[0]) }}" class="btn btn-sm btn-primary">
        <i class="fas fa-edit"></i> Edit
    </a>
    {% if session.get('user_id') != user[0] %}
    <form action="{{ url_for('delete_user', user_id=user[0]) }}" method="POST" class="d-inline">
        <button type="submit" class="btn btn-sm btn-danger" onclick="return confirm('Are you sure you want to delete this user?')">
            <i class="fas fa-trash"></i> Delete
        </button>
    </form>
    {% endif %}
</td>
...
```

now what i want is there should be admin and user panel like admin can see the db detatils like what are the user logged in deleted the user , and other functionalyion what admin have , and when user login it ill redifrect to the index.html page and there will also hace aonptopn to logout at in the header
ASSISTANT
You want a clear separation between admin and regular user experience:

- **Admin** logs in ⇒ redirect to admin dashboard showing user management features (list users, delete, edit, etc).
- **User** logs in ⇒ redirect to main app page (`index.html`), with a header showing the username and a logout button.
- Both have the ability to logout.
- Admin *only* can access `/admin` routes.
- User cannot access admin routes.
- Admin is shown admin panel; users see the regular UI.

---

### What you already have:
- Your Flask route `/admin` is protected with `@admin_required`.
- Normal users redirected to `/home` (which renders `index.html`).
- You already have logout route and login sessions working.

---

### What you need to do:
1. **Add role-based redirects after login**:  
   When a user logs in successfully, check their role and redirect accordingly.

2. **Modify your base template or `index.html` to show the username & logout option in the header/nav bar when a user is logged in.**

3. **Create a shared template for header/nav that includes user info and logout — so both admin and user pages can reuse it.**

---

# Step 1: Modify login route for role-based redirect

In your `/login` route:

```python
if user and check_password_hash(user[1], password):
    session['user_id'] = user[0]
    session['username'] = username
    session['role'] = user[2]

    flash(f'Welcome back, {username}!', 'success')

    # Redirect based on role
    if user[2] == 'admin':
        return redirect(url_for('admin_dashboard'))
    else:
        return redirect(url_for('home'))
else:
    flash('Invalid username or password', 'danger')
```

---

# Step 2: Modify Navbar in your main `index.html` (and any other templates like `admin_dashboard.html`)

Add user info with logout link inside the navbar, for example:

```html
<ul class="navbar-nav ms-auto">
    {% if session.get('username') %}
        <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="userDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
                <i class="fas fa-user"></i> {{ session.username }}
            </a>
            <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="userDropdown">
                <li><a class="dropdown-item" href="{{ url_for('profile') }}">Profile</a></li>
                {% if session.get('role') == 'admin' %}
                <li><a class="dropdown-item" href="{{ url_for('admin_dashboard') }}">Admin Dashboard</a></li>
                {% endif %}
                <li><hr class="dropdown-divider"></li>
                <li><a class="dropdown-item" href="{{ url_for('logout') }}">Logout</a></li>
            </ul>
        </li>
    {% else %}
        <li class="nav-item">
            <a class="nav-link" href="{{ url_for('login') }}">Login</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="{{ url_for('register') }}">Register</a>
        </li>
    {% endif %}
</ul>
```

- Put this inside your navbar `<ul class="navbar-nav ms-auto">` section.
- This will show the logged-in username as a dropdown with links to Profile, Admin dashboard (if admin), and Logout.
- For non-logged-in users it will show Login/Register.

---

# Step 3: Reflect the same or similar navbar in your `admin_dashboard.html` template

Example:

```html
<nav class="navbar navbar-expand-lg navbar-dark sticky-top bg-dark">
  <div class="container">
    <a class="navbar-brand" href="{{ url_for('admin_dashboard') }}">Admin Panel</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAdmin" aria-controls="navbarNavAdmin" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavAdmin">
      <ul class="navbar-nav ms-auto">
        {% if session.get('username') %}
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="adminUserDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
                <i class="fas fa-user-shield"></i> {{ session.username }}
            </a>
            <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="adminUserDropdown">
              <li><a class="dropdown-item" href="{{ url_for('profile') }}">Profile</a></li>
              <li><a class="dropdown-item" href="{{ url_for('home') }}">Main App</a></li>
              <li><hr class="dropdown-divider"></li>
              <li><a class="dropdown-item" href="{{ url_for('logout') }}">Logout</a></li>
            </ul>
          </li>
        {% endif %}
      </ul>
    </div>
  </div>
</nav>
```

---

# Optional: DRY up your navbars  
You can create a reusable `navbar.html` partial, and include it with `{% include 'navbar.html' %}` in all templates.

Example `navbar.html`:

```html
<nav class="navbar navbar-expand-lg navbar-dark sticky-top bg-dark">
  <div class="container">
    <a class="navbar-brand" href="{{ url_for('home') }}">EmoSense</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavMain" aria-controls="navbarNavMain" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavMain">
      <ul class="navbar-nav ms-auto">
        {% if session.get('username') %}
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="userDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
                <i class="fas fa-user"></i> {{ session.username }}
            </a>
            <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="userDropdown">
              <li><a class="dropdown-item" href="{{ url_for('profile') }}">Profile</a></li>
              {% if session.get('role') == 'admin' %}
              <li><a class="dropdown-item" href="{{ url_for('admin_dashboard') }}">Admin Dashboard</a></li>
              {% endif %}
              <li><hr class="dropdown-divider"></li>
              <li><a class="dropdown-item" href="{{ url_for('logout') }}">Logout</a></li>
            </ul>
          </li>
        {% else %}
          <li class="nav-item"><a class="nav-link" href="{{ url_for('login') }}">Login</a></li>
          <li class="nav-item"><a class="nav-link" href="{{ url_for('register') }}">Register</a></li>
        {% endif %}
      </ul>
    </div>
  </div>
</nav>
```

Then in your templates:

```html
<body>
    {% include 'navbar.html' %}
    <!-- rest of your template -->
</body>
```

### Summary
- Add role check in login route redirection.
- Show username + logout in navbar for all logged-in users.
- Admin can access `/admin` routes only.
- Admin panel lists users with edit/delete.
- Regular users see main app page.
- Both can logout.

---

If you want, I can help generate the updated `login()` function and your navbar snippet again, or help create a base layout template to include the navbar. Just ask!
