How to test django model method __str__()

Question

I trying to test __str__ method, and when trying to access it in my test it returns my model instance (I think it is)

def test_str_is_equal_to_title(self):
    """
    Method `__str__` should be equal to field `title`
    """
    work = Work.objects.get(pk=1)
    self.assertEqual(work.__str__, work.title)

And from test I get:

AssertionError: '<bound method Work.__str__ of <Work: Test title>>' != 'Test title'

How I should compare these 2 values to pass test?

Answer 1

According to the documentation :

Model.__str__()

The __str__() method is called whenever you call str() on an object.

You need to call str() on the model instance:

self.assertEqual(str(work), work.title)

Answer 2

或者，你可以简单地称它为：

model_instance.__str__()
