如何测试Django模型方法__str __() [英] How to test django model method __str__()

问题描述

我尝试测试__str__方法，并且在测试中尝试访问它时，它返回我的模型实例(我认为是)

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)

从测试中我得到:

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

我应该如何比较这两个值以通过测试?

How I should compare these 2 values to pass test?

推荐答案

根据文档:

Model .__ str __()

每次调用时都会调用 __ str __()方法在对象上 str().

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

您需要在模型实例上调用 str():

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

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