Flask.url_for() error: Attempted to generate a URL without the application context being pushed

Question

I have a trivial app where I\'m trying to redirect the favicon per:

http://flask.pocoo.org/docs/0.10/patterns/favicon/

app = flask.Flask(__name__)
ap         


        

Answer 1

According to the doc:

Setting a SERVER_NAME also by default enables URL generation without a request context but with an application context.

since you're using app_context, you may set the SERVER_NAME Configuration Value.

By the way, as the doc:Adding a favicon says:

the above line should be enough for most browsers, we don't have to do any other things.
