Re: 'NoneType' object has no attribute 'datetime' bug?

I had a similar problem in one of my views. It looked like:

from X import y

def my_func():
foo = y.baz()
...
y = foo + bar;

Since I was assigning to y later in the function, "y" represented a local variable throughout the function. Somewhere you have "datetime =", but it might be later in the method.
