crud-forge 0.1.1

A package for generating FastAPI CRUD operations and routes

CRUD FORGE

CRUD FORGE is a powerful Python package that simplifies the creation of CRUD (Create, Read, Update, Delete) operations for FastAPI applications. It automatically generates API routes and database models based on your SQLAlchemy models, saving you time and reducing boilerplate code.

Features

• Automatic generation of CRUD routes for FastAPI
• Support for SQLAlchemy models and Pydantic schemas
• Flexible database connection management
• Easy-to-use API for creating models and routes
• Customizable route generation
• Built-in filtering for GET requests
• Comprehensive error handling
• Type hinting for better IDE support

Installation

Install FastAPI CRUD Generator using pip:

pip install crud-forge

Quick Start

Here's a simple example of how to use FastAPI CRUD Generator:

from fastapi import FastAPI
from sqlalchemy import Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from pydantic import BaseModel
from crud_forge.generators import generate_crud
from crud_forge.db import DatabaseManager

# Define your SQLAlchemy model
Base = declarative_base()

class User(Base):
    __tablename__ = "users"
    id = Column(Integer, primary_key=True, index=True)
    name = Column(String, index=True)
    email = Column(String, unique=True, index=True)

# Define your Pydantic model
class UserSchema(BaseModel):
    id: int
    name: str
    email: str

    class Config:
        orm_mode = True

# Set up FastAPI app and database
app = FastAPI()
db_manager = DatabaseManager(db_url="postgresql://user:password@localhost/dbname")

# Generate CRUD routes
generate_crud(User, UserSchema, app, db_manager.get_db)

# Run the app
if __name__ == "__main__":
    import uvicorn
    uvicorn.run(app, host="0.0.0.0", port=8000)

Package Structure

This example sets up a simple User model and generates CRUD routes for it.

Usage

Setting up the Database Connection

Use the DatabaseManager class to manage your database connection:

from crud_forge.db import DatabaseManager

db_manager = DatabaseManager(
    user="myuser",
    password="mypassword",
    host="localhost",
    database="mydatabase"
)

Or provide a complete database URL:

db_manager = DatabaseManager(db_url="postgresql://user:password@localhost/dbname")

Generating Models

Use the generators.models module to generate SQLAlchemy & Pydantic models from your database:

from crud_forge.generators.models import generate_models, generate_views
from crud_forge.db import DatabaseManager

db_manager = DatabaseManager(db_url="postgresql://user:password@localhost/dbname")

store_models = generate_models(db_manager.engine, ['store'])
store_views = generate_views(db_manager.engine, ['store'])

Creating CRUD Routes

Use the create_crud_routes function to automatically generate CRUD routes for your models:

from crud_forge.generators.crud import generate_crud

generate_crud(sqlalchemy_model, pydantic_model, router, db_dependency)

This will create the following routes:

• GET /users/columns: Get all columns of the User model
• POST /users: Create a new user
• GET /users: Get all users (with optional filtering)
• PUT /users: Update users (with filtering)
• DELETE /users: Delete users (with filtering)
