flask-require 0.0.4

A simple Flask extension for requiring parameters in a request.

flask_require

This is a simple library to help you write cleaner flask code.

Installation

pip install git+https://github.com/ivario123/flask_require

Usage

from flask import Flask,request
import require

app = Flask(__name__)

@app.route('/')
@require.fields(request)
def index(name):
    return f"Hello, {name}!"

if __name__ == '__main__':
    app.run()

fields with optional response_formatter

import flask
import require

app = flask.Flask(__name__)

def __response(name, description="", code=200):
    formatter_response = {"name": name, "description": description}

    return flask.make_response(dumps(formatter_response), code)

@app.route("/")
@fields(flask.request, response_formatter=__response)
def index(path):
    return {"name": "success", "description": "Works as it should"}

if __name__ == '__main__':
    app.run()

Enforcing types

The system will check that the types provided in the signature and the types provided by the caller are the same before passing the arguments to the function.

from flask import Flask,request
import require

app = Flask(__name__)

@app.route('/')
@require.fields(request)
def index(name:str):
    return f"Hello, {name}!"

if __name__ == '__main__':
    app.run()

Usage of admin

from flask import Flask,request
from require import fields, admin

app = Flask(__name__)

@app.route('/')
@fields(request)
def index(name):
    return f"Hello, {name}!"

@app.route('/admin')
@admin()
def admin():
    return 'Hello, admin!'

def callback():
    print('Hello, callback!')

@app.route('/admin_with_callback')
@admin(callback)
def admin_with_callback():
    return 'Hello, admin with callback!'
