Easily register a function to execute at the end of the current request.

Installation
~~~~~~~~~~~~

.. code:: bash

pip install Flask-Defer


Usage
~~~~~

Passing a function and it's arguments to `flask_defer.after_request` will register that function to execute when the Flask request has ended.

If a call to `flask_defer.after_request` happens outside of a request context then the function will be executed immediately.

.. code:: python

from flask import Flask
from flask_defer import FlaskDefer, after_request

app = Flask(__name__)
FlaskDefer(app)


def defer_me(name, say_hello=False):
if say_hello:
print 'Saying hello to, {name}'.format(name=name)


@app.route('/')
def index():
print 'Start of request method'

# Defer `defer_me` until after the current request has finished
after_request(defer_me, 'name', say_hello=True)

print 'Ending request method'

return 'Thanks!'


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


.. code:: bash
