ImportError: No module named models

I am going a tad crazy here. I keep getting this error: ImportError: No module named models and I am not sure why. Here is what I have found so far...

>>>开发者_Go百科 from django.shortcuts import get_object_or_404, redirect
>>> from mystore.cart import cart
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Users/Jeff/django/mystore/cart/cart.py", line 3, in <module>
  from mystore.cart.models import CartItem
ImportError: No module named models
>>> 

I am not sure what's going on with this... line 3 in cart.py is this:

from mystore.cart.models import CartItem

If I try to do: from mystore.cart.models import CartItem it works fine...

Any suggestions?

Almost certainly, you have a circular dependency: mystore.cart.cart is importing mystore.cart.models, which in turn is trying to import mystore.cart.cart.

You should determine if both of those imports are necessary, and if either of them could be moved out of the global scope into a function or method.

---

Why are you doing from mystore.cart import cart? That should be just from mystore import cart.

---

Very early in the mystore.cart.models an error is occurring that's why nothing in models.py can be imported. The error can be a circular import, a conditional statement that's triggered during runtime but not at the command prompt or is happening inside something else your are importing at the beginning of models.py

You have to put a point before.

bad

from models import *

good

from .models import * 

that means that is at the same level.
