Testing get_context_data() on ListView throws 'AttributeError: object has no attribute 'object_list'
Testing get_context_data() on ListView throws 'AttributeError: object has no attribute 'object_list'
我正在尝试在 ListView 上测试我的自定义 get_context_data() 方法,但我一直 运行 出现此错误:AttributeError: 'Home' object has no attribute 'object_list'
视图效果很好。测试视图以 200 状态代码响应工作正常。我似乎无法测试我的自定义 get_context_data 方法。

问题是您没有使用标准 as_view()
函数。
如果您想手动执行此操作,您需要自己设置 self.object_list
(这发生在主 view
函数中,例如 get
)。
试试这个:
def test_number_of_peaks_completed(factory):
mixer.cycle(7).blend(Peak, complete=True)
mixer.cycle(10).blend(Peak)
path = reverse('home')
request = factory.get(path)
view = Home()
view.setup(request)
view.object_list = view.get_queryset()
context = view.get_context_data()
assert context['number_of_peaks_completed'] == 7
您也可以将此行移至您自己的 get_context_data
。
