Where do I put my blueprint before_request

Question

So I have the before request routing for my user module. But now I want to access g.users from other blueprints as well. I found the only way to do it, is to copy the code below to every single blueprint.

I tried putting it in my app.py for @app.before_request, but then you have errors because you have to import session, g, User, and then still you get _requestglobal errors in other places.

@app.before_request
def before_request():
  g.user = None
  if 'user_id' in session:
    g.user = User.query.get(session['user_id']);

What's the best place to put it?

I get a lot of:

AttributeError: '_RequestGlobals' object has no attribute 'user'

Answer 1

Blueprint.before_request is called before each request within the blueprint. If you want to call it before all blueprints, please use before_app_request.

Answer 2

A little late here but:
This is what I do:
Use the Blueprint variable to set the before request

myblueprint = Blueprint('myblueprint', __name__, template_folder="templates")

def before_myblueprint():
    #code here

myblueprint.before_request(before_myblueprint)
