+## Introduction to Flask
+
+Flask is a lightweight WSGI web application framework written in Python. It's designed to be simple and easy to use, while also being powerful enough to build complex web applications. Created by Armin Ronacher, Flask is often referred to as a "micro" framework because it doesn't require particular tools or libraries, giving developers the flexibility to choose their preferred tools and libraries.
+
+### Key Features
+- Lightweight and modular design
+- Built-in development server and debugger
+- RESTful request dispatching
+- Jinja2 templating engine
+- Secure cookies support
+- Unicode-based
+- Extensive documentation
+- Large community and ecosystem
+
+## Setting Up Your Development Environment
+
+### Prerequisites
+- Python 3.7 or higher
+- pip (Python package installer)
+- Virtual environment tool (venv or virtualenv)
+
+### Step-by-Step Setup
+
+1. **Create a new project directory**
+```bash
+mkdir myflaskapp
+cd myflaskapp
+```
+
+2. **Create and activate a virtual environment**
+```bash
+# On Windows
+python -m venv venv
+venv\Scripts\activate
+
+# On macOS/Linux
+python3 -m venv venv
+source venv/bin/activate
+```
+
+3. **Install Flask**
+```bash
+pip install flask
+```
+
+4. **Create requirements.txt**
+```bash
+pip freeze > requirements.txt
+```
+
+5. **Basic Project Structure**
+```

+
+## Basic Flask Concepts
+
+### Creating Your First Application
+
+1. **Create app.py**
+```python
+from flask import Flask
+
+app = Flask(__name__)
+
+@app.route('/')
+def hello_world():
+    return 'Hello, World!'
+
+if __name__ == '__main__':
+    app.run(debug=True)
+```
+
+2. **Run the application**
+```bash
+python app.py
+```
+
+### Understanding the Flask Application Context
+Flask uses contexts to make certain variables globally accessible to a thread without interfering with other threads. There are two types of contexts:
+
+1. **Application Context**
+- `current_app`: The active application instance
+- `g`: Object for storing temporary data during request
+
+2. **Request Context**
+- `request`: Contains HTTP request data
+- `session`: User session dictionary
+
+## Routing and Views
+
+### Basic Routing
+```python
+@app.route('/')
+def index():
+    return 'Index Page'
+
+@app.route('/hello')
+def hello():
+    return 'Hello, World'
+```
+
+### Dynamic Routes
+```python
+@app.route('/user/<username>')
+def show_user_profile(username):
+    return f'User {username}'
+
+@app.route('/post/<int:post_id>')
+def show_post(post_id):
+    return f'Post {post_id}'
+```
+
+### HTTP Methods
+```python
+@app.route('/login', methods=['GET', 'POST'])
+def login():
+    if request.method == 'POST':
+        return do_login()
+    else:
+        return show_login_form()
+```
+
+## Templates and Jinja2
+
+### Basic Template Usage
+```python
+from flask import render_template
+
+@app.route('/hello/<name>')
+def hello(name):
+    return render_template('hello.html', name=name)
+```
+
+### Template Structure (hello.html)
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>{{ title }}</title>
+</head>
+<body>
+    <h1>Hello, {{ name }}!</h1>
+</body>
+</html>
+```
+
+### Template Inheritance
+**base.html**
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>{% block title %}{% endblock %}</title>
+</head>
+<body>
+    {% block content %}{% endblock %}
+</body>
+</html>
+```
+
+**child.html**
+```html
+{% extends "base.html" %}
+
+{% block title %}Page Title{% endblock %}
+
+{% block content %}
+    <h1>This is the content</h1>
+{% endblock %}
+```
+
+## Working with Forms
+
+### Using Flask-WTF
+```bash
+pip install flask-wtf
+```
+
+### Form Creation
+```python
+from flask_wtf import FlaskForm
+from wtforms import StringField, PasswordField, SubmitField
+from wtforms.validators import DataRequired, Email
+
+class LoginForm(FlaskForm):
+    email = StringField('Email', validators=[DataRequired(), Email()])
+    password = PasswordField('Password', validators=[DataRequired()])
+    submit = SubmitField('Log In')
+```
+
+### Form Handling
+```python
+@app.route('/login', methods=['GET', 'POST'])
+def login():
+    form = LoginForm()
+    if form.validate_on_submit():
+        # Process the form data
+        return redirect(url_for('index'))
+    return render_template('login.html', form=form)
+```
+
+## Database Integration
+
+### Using SQLAlchemy
+```bash
+pip install flask-sqlalchemy
+```
+
+### Database Configuration
+```python
+from flask_sqlalchemy import SQLAlchemy
+
+app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///site.db'
+db = SQLAlchemy(app)
+```
+
+### Model Definition
+```python
+class User(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    username = db.Column(db.String(80), unique=True, nullable=False)
+    email = db.Column(db.String(120), unique=True, nullable=False)
+    posts = db.relationship('Post', backref='author', lazy=True)
+
+class Post(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    title = db.Column(db.String(100), nullable=False)
+    content = db.Column(db.Text, nullable=False)
+    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)
+```
+
+### Database Operations
+```python
+# Create
+new_user = User(username='john', email='john@example.com')
+db.session.add(new_user)
+db.session.commit()
+
+# Read
+user = User.query.filter_by(username='john').first()
+
+# Update
+user.email = 'new_email@example.com'
+db.session.commit()
+
+# Delete
+db.session.delete(user)
+db.session.commit()
+```
+
+## User Authentication
+
+### Using Flask-Login
+```bash
+pip install flask-login
+```
+
+### Setup
+```python
+from flask_login import LoginManager, UserMixin
+
+login_manager = LoginManager()
+login_manager.init_app(app)
+login_manager.login_view = 'login'
+
+class User(UserMixin, db.Model):
+    # User model implementation
+    pass
+
+@login_manager.user_loader
+def load_user(user_id):
+    return User.query.get(int(user_id))
+```
+
+### Authentication Views
+```python
+from flask_login import login_user, logout_user, login_required
+
+@app.route('/login', methods=['GET', 'POST'])
+def login():
+    if current_user.is_authenticated:
+        return redirect(url_for('index'))
+    form = LoginForm()
+    if form.validate_on_submit():
+        user = User.query.filter_by(email=form.email.data).first()
+        if user and user.check_password(form.password.data):
+            login_user(user, remember=form.remember_me.data)
+            return redirect(url_for('index'))
+    return render_template('login.html', form=form)
+
+@app.route('/logout')
+@login_required
+def logout():
+    logout_user()
+    return redirect(url_for('index'))
+```
+
+## RESTful API Development
+
+### Basic API Structure
+```python
+from flask import jsonify, request
+
+@app.route('/api/users', methods=['GET'])
+def get_users():
+    users = User.query.all()
+    return jsonify([{
+        'id': user.id,
+        'username': user.username,
+        'email': user.email
+    } for user in users])
+
+@app.route('/api/users/<int:user_id>', methods=['GET'])
+def get_user(user_id):
+    user = User.query.get_or_404(user_id)
+    return jsonify({
+        'id': user.id,
+        'username': user.username,
+        'email': user.email
+    })
+```
+
+### Error Handling
+```python
+@app.errorhandler(404)
+def not_found_error(error):
+    return jsonify({'error': 'Not found'}), 404
+
+@app.errorhandler(500)
+def internal_error(error):
+    db.session.rollback()
+    return jsonify({'error': 'Internal server error'}), 500
+```
+

+        app.config.from_object(TestConfig)
+        self.app = app.test_client()
+        db.create_all()
+
+    def tearDown(self):
+        db.session.remove()
+        db.drop_all()
+
+    def test_password_hashing(self):
+        u = User(username='test')
+        u.set_password('test')
+        self.assertFalse(u.check_password('wrong'))
+        self.assertTrue(u.check_password('test'))
+```
+
+## Deployment
+
+### Production Server Setup (using Gunicorn)
+```bash
+pip install gunicorn
+```
+
+### Sample wsgi.py
+```python
+from app import app
+
+if __name__ == "__main__":
+    app.run()
+```
+
+### Running with Gunicorn
+```bash
+gunicorn -w 4 wsgi:app
+```
+
+### Basic Nginx Configuration
+```nginx
+server {
+    listen 80;
+    server_name yourdomain.com;
+
+    location / {
+        proxy_pass http://127.0.0.1:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```

+```
+
+#### Implementation
+
+1. **Models (models.py)**
+```python
+from app import db
+from datetime import datetime
+
+class Product(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    name = db.Column(db.String(100), nullable=False)
+    description = db.Column(db.Text)
+    price = db.Column(db.Float, nullable=False)
+    stock = db.Column(db.Integer, default=0)
+    category_id = db.Column(db.Integer, db.ForeignKey('category.id'))
+    created_at = db.Column(db.DateTime, default=datetime.utcnow)
+    updated_at = db.Column(db.DateTime, default=datetime.utcnow, 
+                          onupdate=datetime.utcnow)
+
+class Category(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    name = db.Column(db.String(50), nullable=False)
+    products = db.relationship('Product', backref='category', lazy=True)
+```
+
+2. **Schemas (schemas.py)**
+```python
+from marshmallow import Schema, fields
+
+class CategorySchema(Schema):
+    id = fields.Int(dump_only=True)
+    name = fields.Str(required=True)
+
+class ProductSchema(Schema):
+    id = fields.Int(dump_only=True)
+    name = fields.Str(required=True)
+    description = fields.Str()
+    price = fields.Float(required=True)
+    stock = fields.Int(required=True)
+    category_id = fields.Int(required=True)
+    created_at = fields.DateTime(dump_only=True)
+    updated_at = fields.DateTime(dump_only=True)
+```
+
+3. **Routes (routes/products.py)**
+```python
+from flask import Blueprint, jsonify, request
+from app.models import Product, Category
+from app.schemas import ProductSchema, CategorySchema
+from app import db
+
+api = Blueprint('api', __name__)
+product_schema = ProductSchema()
+products_schema = ProductSchema(many=True)
+
+@api.route('/products', methods=['GET'])
+def get_products():
+    products = Product.query.all()
+    return jsonify(products_schema.dump(products))
+
+@api.route('/products', methods=['POST'])
+def create_product():
+    data = request.get_json()
+    
+    try:
+        product_data = product_schema.load(data)
+    except ValidationError as err:
+        return jsonify(err.messages), 400
+        
+    product = Product(**product_data)
+    db.session.add(product)
+    db.session.commit()
+    
+    return jsonify(product_schema.dump(product)), 201
+
+@api.route('/products/<int:product_id>', methods=['PUT'])
+def update_product(product_id):
+    product = Product.query.get_or_404(product_id)
+    data = request.get_json()
+    
+    try:
+        product_data = product_schema.load(data, partial=True)
+    except ValidationError as err:
+        return jsonify(err.messages), 400
+        
+    for key, value in product_data.items():
+        setattr(product, key, value)
+        
+    db.session.commit()
+    return jsonify(product_schema.dump(product))
+
+@api.route('/products/<int:product_id>', methods=['DELETE'])
+def delete_product(product_id):
+    product = Product.query.get_or_404(product_id)
+    db.session.delete(product)
+    db.session.commit()
+    return '', 204
+```
+
+### Project 3: Task Management System
+
+A task management application with user roles, task assignment, and real-time updates.
+
+#### Key Features
+- User authentication with roles (Admin, Manager, Employee)
+- Task creation, assignment, and tracking
+- Real-time notifications using WebSocket
+- File attachments for tasks
+- Task comments and activity log
+- Dashboard with task analytics
+
+#### Implementation Highlights
+
+1. **User Roles and Permissions**
+```python
+from enum import Enum
+from functools import wraps
+from flask_login import current_user
+from flask import abort
+
+class UserRole(Enum):
+    ADMIN = 'admin'
+    MANAGER = 'manager'
+    EMPLOYEE = 'employee'
+
+def role_required(role):
+    def decorator(f):
+        @wraps(f)
+        def decorated_function(*args, **kwargs):
+            if not current_user.has_role(role):
+                abort(403)
+            return f(*args, **kwargs)
+        return decorated_function
+    return decorator
+
+class User(UserMixin, db.Model):
+    # ... other fields ...
+    role = db.Column(db.Enum(UserRole), nullable=False, default=UserRole.EMPLOYEE)
+    
+    def has_role(self, role):
+        return self.role == role
+```
+
+2. **Task Management**
+```python
+class Task(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    title = db.Column(db.String(100), nullable=False)
+    description = db.Column(db.Text)
+    due_date = db.Column(db.DateTime)
+    status = db.Column(db.String(20), default='pending')
+    priority = db.Column(db.String(20))
+    assigned_to_id = db.Column(db.Integer, db.ForeignKey('user.id'))
+    created_by_id = db.Column(db.Integer, db.ForeignKey('user.id'))
+    created_at = db.Column(db.DateTime, default=datetime.utcnow)
+    
+    attachments = db.relationship('TaskAttachment', backref='task', lazy=True)
+    comments = db.relationship('TaskComment', backref='task', lazy=True)
+    activities = db.relationship('TaskActivity', backref='task', lazy=True)
+
+class TaskActivity(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    task_id = db.Column(db.Integer, db.ForeignKey('task.id'))
+    user_id = db.Column(db.Integer, db.ForeignKey('user.id'))
+    action = db.Column(db.String(50))
+    details = db.Column(db.Text)
+    timestamp = db.Column(db.DateTime, default=datetime.utcnow)
+```
+
+3. **Real-time Notifications using WebSocket**
+```python
+from flask_socketio import SocketIO, emit
+from app import socketio
+
+@socketio.on('connect')
+def handle_connect():
+    if current_user.is_authenticated:
+        join_room(f'user_{current_user.id}')
+        join_room(f'role_{current_user.role.value}')
+
+def notify_task_update(task_id, action, data):
+    task = Task.query.get(task_id)
+    if task:
+        # Notify assigned user
+        emit('task_update', {
+            'action': action,
+            'task_id': task_id,
+            'data': data
+        }, room=f'user_{task.assigned_to_id}')
+        
+        # Notify managers
+        emit('task_update', {
+            'action': action,
+            'task_id': task_id,
+            'data': data
+        }, room=f'role_{UserRole.MANAGER.value}')
+```
+
+4. **Dashboard Analytics**
+```python
+@app.route('/dashboard')
+@login_required
+def dashboard():
+    # Task statistics
+    total_tasks = Task.query.count()
+    pending_tasks = Task.query.filter_by(status='pending').count()
+    completed_tasks = Task.query.filter_by(status='completed').count()
+    
+    # Tasks by priority
+    priority_stats = db.session.query(
+        Task.priority, 
+        db.func.count(Task.id).label('count'))
