NameError: name 'ask' is not defined

Question

problem with flask ask

@ask.launch issue

am having problem running my python flask script. I am using python 2.7, the error says: File "C:\Users\user1\AppData\Local\Continuum\anaconda2\Lib\site-packages\hello_lumion.py", line 13, in @ask.launch NameError: name 'ask' is not defined

import logging
import os 


from flask import request
from flask import Flask

from flask_ask import Ask, statement, request, context, session, question,  version

import requests


@ask.launch
def welcome():
    return statement ('Welcome to Foo')


app = Flask(__name__)

ask= Ask(app,"/")

logging.getLogger("flask_ask").setLevel(logging.DEBUG)

@ask.intent("Hello")

def hello():
    msg= "hello from lumion"
    return statement (msg)


if __name__ == '__main__':
    port = 9000
    app.run(host='0.0.0.0', port=port)
    app.run(debug=True) 

any advice on how to overcome this issue?

Answer 1

You are calling ask before it is defined. In your code you have

@ask.launch # ask has not been made
def welcome():
    return statement ('Welcome to Foo')


app = Flask(__name__)

ask= Ask(app,"/") # ask gets made here!

You will need to reorder it so when you call ask, it has been defined. Something like:

app = Flask(__name__)

ask= Ask(app,"/") # define it first

@ask.launch # now use it
def welcome():
    return statement ('Welcome to Foo')
