python - Flask: Getting at Blueprint options in view code -

flask's blueprints let me pass optional values when register blueprint. how them later?

from flask import blueprint, g  bp = blueprint('test', __name__, url_prefix='/test')  @bp.route('/') def index():     ... value of `foo` from? ...  app.register_blueprint(bp, foo="bar") 

as far can see options pass in register_blueprint used flask's internal setup of blueprint (e.g. configuring url_prefix, subdomain, etc. options). aren't available @ request time.

maybe helpful if explain why want access value within request?

have considered using pluggable view?

http://flask.pocoo.org/docs/views/

with views can subclass view, override __init__ pass values in usable within request.

you can subclass blueprint , same thing, it's little more code & complexity. did here (see blueprintwrapper). although if rewrite try rid of metaclass.
