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

   $ python example.py

    * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

   Start of request method

   Ending request method

   Saying hello to, name
