pyframex7 0.2.0

This is simple python web framework which written for learning purposes

pyframex7

Pyframex7 is a custom Python web framework created for learning purposes.

Features

• Minimal and easy to understand
• Custom middleware support
• Simple request/response handling
• Supports both class-based and function-based handlers
• Designed for educational use

Installation

pyframex7 is available on PyPI and can be installed with:

pip install pyframex7

Simple Use Cases

1. Function-Based Handler Example

from pyframe.app import PyFramework
from pyframe.response import Response

app = PyFramework()

# Function-based route handler
@app.router("/hello/{name}")
def hello(request, response, name):
    # Set plain text response
    response.text = f"Hello, {name}!"

# To run: Use a WSGI server like gunicorn or waitress
# Example: gunicorn main:app

2. Class-Based Handler Example

from pyframe.app import PyFramework

app = PyFramework()

# Class-based handler for /greet/
@app.router("/greet/")
class Greet:
    def get(self, request, response):
        response.text = "Greetings from a class-based handler!"

    def post(self, request, response):
        # You can access POST data from request.params
        name = request.params.get("name", "Anonymous")
        response.text = f"Posted by {name}"

3. Using Middleware

from pyframe.middleware import Middleware

class LoggingMiddleware(Middleware):
    def process_request(self, request):
        print(f"Request path: {request.path}")

    def process_response(self, request, response):
        print(f"Response status: {response.status_code}")

# Add middleware to the app
app.add_middleware(LoggingMiddleware)

4. Simple ORM Model and Usage

from pyframe.orm import Table, Column, Database

# Define a User model/table
class User(Table):
    id = Column(int)
    name = Column(str)
    age = Column(int)

# Create a database instance (in-memory for demo)
db = Database(":memory:")

# Register the model and create the table
db.create(User)

# Now the User model is bound to the database

# Create and save multiple users
user1 = User(id=1, name="Alice", age=30)
user2 = User(id=2, name="Bob", age=25)
user3 = User(id=3, name="Charlie", age=35)
user1.save()
user2.save()
user3.save()

# Fetch all users
users = User.all()
print("All users:", users)

# Get a single user by field (raises if not found or multiple found)
try:
    alice = User.get(name="Alice")
    print("Get Alice:", alice)
except Exception as e:
    print(e)

# Filter users by age
filtered = User.filter(age=25)
print("Users with age=25:", filtered)

# Delete a user by id
User.delete(id=2)
print("After deleting Bob:", User.all())

# Drop the table (removes all data and table)
db.drop(User)

Comments

• The framework supports both function-based and class-based route handlers.
• Middleware can be added for logging, authentication, etc.
• The ORM allows you to define models as Python classes and map them to SQL tables.
• You must bind a database connection to your model before saving data.
• Table creation and data insertion are handled via class methods and instance methods.

---

Use Cases

• Learning how web frameworks work
• Experimenting with middleware and routing
• Building simple web applications for educational purposes
