Flask-login Breaks When My Decorator Accepts Parameters

Thanks to what I learned from this question, I've been able to make a Flask-Login process with a endpoint like this: @app.route('/top_secret') @authorize @login_required def top_se

Solution 1:

Decorating a function is equivalent to re-binding the name to the result of calling the decorator with the function.

@authorizedeftop_secret():
    ...

# is equivalent todeftop_secret():
    ...
top_secret = authorize(top_secret)

The function you've written is a decorator factory: you call it, with an optional argument, to get a decorator.

@authorize()
deftop_secret():
    ...

# is equivalent todeftop_secret():
    ...
top_secret = authorize()(top_secret)

Currently, you're passing top_secret as the group argument to the factory, so you're never actually creating a route. Since there's no route, there's no url to build either.
