📦 Installation

pip install fastapi-pundra

🛠️ Quick Start

Basic Setup

from fastapi import FastAPI
from fastapi_pundra.rest.global_exception_handler import setup_exception_handlers
from fastapi_pundra.common.password import generate_password_hash, compare_hashed_password

app = FastAPI()

# Setup global exception handling
setup_exception_handlers(app)

@app.get("/")
async def root():
    return {"message": "Hello from FastAPI Pundra!"}

Password Management

from fastapi_pundra.common.password import generate_password_hash, compare_hashed_password

# Hash a password
password = "my_secure_password"
hashed = generate_password_hash(password)

# Verify a password
is_valid = compare_hashed_password(password, hashed)
print(is_valid)  # True

Email Sending

from fastapi import BackgroundTasks
from fastapi_pundra.common.mailer.mail import send_mail, send_mail_background

# Send email directly
await send_mail(
    subject="Welcome!",
    to=["[e-mail]"],
    template_name="welcome_email.html",
    context={"username": "John Doe"}
)

# Send email in background
async def send_welcome_email(background_tasks: BackgroundTasks):
    await send_mail_background(
        background_tasks=background_tasks,
        subject="Welcome!",
        to=["[e-mail]"],
        template_name="welcome_email.html",
        context={"username": "John Doe"}
    )

Pagination

from fastapi import Request
from fastapi_pundra.rest.paginate import paginate

@app.get("/users")
async def get_users(request: Request):
    # Assuming you have a SQLAlchemy query
    query = session.query(User)
    return paginate(
        request=request,
        query=query,
        serilizer=UserSerializer,
        the_page=1,
        the_per_page=10
    )

Celery Task Scheduling

from fastapi_pundra.common.scheduler.celery import create_celery_app

# Create Celery app
celery_app = create_celery_app("my_project")

@celery_app.task
def my_scheduled_task():
    print("This task runs on schedule!")
    return "Task completed"

GraphQL with Strawberry

import strawberry
from fastapi_pundra.gql_berry.common_gql_type import PaginatedList

@strawberry.type
class User:
    id: int
    name: str
    email: str

@strawberry.type
class Query:
    @strawberry.field
    def users(self) -> PaginatedList[User]:
        # Your logic here
        return PaginatedList(
            data=[User(id=1, name="John", email="[e-mail]")],
            pagination={"page": 1, "total": 1}
        )
