AttributeError for imported class with Flask

I am importing a class termIndex. The class works fine on its own, but I am getting a "AttributeError: 'function' object has no attribute 'search' when I call the class's search function from within another function.

from flask import Flask, request
from TermIndex import termIndex

index = termIndex()
index.load(pickleFile) # No problem here
index.search(term) # No problem here

...

@app.route('/data')
def data():
    index.search(term) # This is where I get the Attribute Error

I've tried throwing in global index at the start of the data function but that didn't help.

EDIT: Like so, I get no error:

@app.route('/data')
def data():
    index = termIndex()
    index.load(pickleFile)
    index.search(term)

and like so, I get no error:

index = termIndex()
index.load(pickleFile)

def data():
    index.search(term)

data()

Which is why I've tagged flask.

From the error message you describe, it's likely that you are defining an index function in the ... part of your code that you've left out of the question. That makes it impossible for data to see the original index value, it sees the function instead.

Here's a simpler example of the same issue:

x = "foo bar"
x.split()          # this works here, since the name x refers to a string

def x(): pass      # this rebinds the name x to a function

x.split()          # raises an AttributeError since functions don't have a split method

To fix the problem, you just need to rename either the index function or rename the index variable you've shown us.
