Flask: How to run a method before every route in a blueprint?

Question

I want to make my Flask Blueprint always run a method before executing any routes. Instead of decorating every route method in my blueprint with a custom decorator, I want to be able to do something like this:

def my_method():
    do_stuff

section = Blueprint('section', __name__)

# Register my_method() as a setup method that runs before all routes
section.custom_setup_method(my_method())

@section.route('/two')
def route_one():
    do_stuff

@section.route('/one')
def route_two():
    do_stuff

Then basically both /section/one and /section/two will run my_method() before executing code in route_one() or route_two().

Is there a way to do this?

Answer 1

You can use before_request for this:

@section.before_request
def before_request():
    do_stuff

Answer 2

You can use the before_request decorator for blueprints. Like this:

@section.before_request
def my_method():
    do_stuff

This automatically registers the function to run before any routes that belong to the blueprint.
