[Flask] Blueprints Question ...

[Ben Duncan]

Thanks all - Especially Paul ...

Now, I'm getting the following error:
RuntimeError

RuntimeError: Working outside of request context. This typically means that
you attempted to use functionality that needed an active HTTP request.

My main process, wtform.py looks like this :
.... (all the necessary imports for flask and wtforms and sqlalchemy) ....
......
app = Flask(__name__)
app.config.from_pyfile('config.cfg')

flask_session = Session()
flask_session.init_app(app)

session = {'modified': False }
session = {'route': None }

# import blueprinted applications here:
from setup.setup import setup

# register blueprinted applications here:
app.register_blueprint(setup, url_prefix='/setup')
.........

The directory 'setup' contains:
   __init__.py             (empty)
  setup.py                 (the module)

and setup.py has this:
# setup - /setup/setup
from flask import g, Blueprint, render_template, abort
from flask import session

setup = Blueprint('setup', __name__)

print "SETUP: Session what is our route? :", session['route']

# @setup.route('/<user_url_slug>')
@setup.route('/')
def dummy():"from setup.setup" to before the "
    # Do some stuff
    return render_template('setup/dummy.html')

So, what AM I doing wrong ?

I tried moving the "app = Flask(__name__)" in wtform.py and it made no
difference

*Thanks for all the help !!!! No Really ....*
