我正在尝试访问将要发送到模板的对象'wine'。基本上，在这个例子中，我有通过瓶子，玻璃或两者出售的葡萄酒。我进行的第一次测试应该能够检索发送到模板的“葡萄酒”对象中的所有3种葡萄酒。 （create_wine（）是一个自定义的Wine.objects.create（）方法）。
如果你注意到，我正在使用django.test导入TestCase，所以我有一个self.client对象可供使用。另外，如果您注意到，我正在向您展示我在'（调试）'文本中尝试去顶的位置。
我真正想要的是预呈现的json。在我看来，视图使用对象呈现html来创建它需要的html并返回它。那么如何访问这个预渲染对象？
问题是我将使用相同的视图来渲染这些葡萄酒对象。如果可能的话，我想使用相同的模板，这意味着将数据发送到视图并重写它，以便在渲染之前抓取正确的葡萄酒。我觉得这没关系。如果这打破了django方法论，我全都听见了。
还有其他方法可以解决这个问题，还是我非常接近？

答案 0 :(得分：2)
您误解了测试客户端的工作原理。当您致电self.client.get("/wine/")时，它会模拟对/wine/的请求，并调用您的wine_list视图。您不必手动拨打wine_list。
client.get()调用会返回响应。然后，您可以使用响应进行测试断言，并从response.context获取项目。
response = self.client.get("/wine/")
self.assertEqual(response.status_code, 200) # check 200 OK response
wines = response.context['wines'] # this is the list of wines you included in the context
# check that wines is as you expected.
for wine in wines:
# All wines should be active
self.assertTrue(wine.is_active)
