Flask-Caster 0.1.0

Example Usage

from flask import Flask
from flask_caster import FlaskCaster

app = Flask(__name__)

caster = FlaskCaster(app)
caster.ints = ['size']
caster.booleans = ['json']
caster.always = ['json']

This will do a few things:

• Assure that the size query parameter is always an integer.

• Assure that the json query parameter is always an boolean.

• Assure that the json query parameter is always present, even if if it wasn’t provided by the end-user.

Assignable properties include ints, booleans, always, and always_default. The always_default property can be set to any value, or to a callable, which will receive one keyword argument: arg_name.

For boolean casting, 0, false, f, and null will automatically be converted to False.

Installation

$ pip install Flask-Caster
