Django Unittest: Typeerror: 'nonetype' Object Is Not Iterable

python3 manage.py test apps.favorites Traceback (most recent call last): File 'manage.py', line 10, in execute_from_command_line(sys.argv) File '/home/dmitry

Solution 1:

This usually happens when you expect a list (or other sequence) returned from a function, but get an empty result of None. If you then give this supposed list to something that requires iteration, such as a simple for loop, you get the error shown. For instance:

>>> oops = None
>>> for i in oops:
...     print i
... 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not iterable
