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
