Python Django测试:即使创建了匹配的查询,也没有匹配的查询
运行Python Django测试:即使创建了匹配的查询,也没有匹配的查询,python,django,database,orm,model,Python,Django,Database,Orm,Model,运行manage.py测试时,我收到以下错误: ====================================================================== ERROR: test_pokemon_detail_view (pokedex.tests.test_views.TestViews) Test the pokemon detail view and ensure the correct template was used ----------------

这通常意味着数据库中没有pokemonderrations对象,但我在setUp函数中创建了它:
def setUp(self):
""" Set Up for testing """
self.pokemon = PokemonFactory(species__evolves_from_species=None)
PokemonGenderRatioFactory(
pokemon__species__evolves_from_species__evolves_from_species=None)
def test_pokemon_detail_view(self):
""" Test the pokemon detail view and ensure the correct template was used """
response = self.client.get(reverse("pokedex:pokemon", args=[self.pokemon.id]))
self.assertEqual(response.status_code, 200)
self.assertTemplateUsed(response, 'pokedex/pokemon.html')
有人知道为什么会出错吗?我试着用--verbosity3
运行测试,但没有给出更多关于测试的细节

有几个子工厂我没有发布,但如果需要可以发布。我不想让事情变得不清楚。默认情况下,你的pokemonderratiofactory
为其外键创建一个新的Pokemon
。你想要的是一个指向你刚刚创建的口袋妖怪:
def setUp(self):
""" Set Up for testing """
self.pokemon = PokemonFactory(species__evolves_from_species=None)
PokemonGenderRatioFactory(
pokemon=self.pokemon, # <-- this should be necessary
)
def设置(自):
“”“为测试设置”“”
self.pokemon=PokemonFactory(物种从物种演化而来=无)
神奇宝贝(
pokemon=self.pokemon,#在test\u pokemon\u detail\u view
中查看代码也会很有帮助。您使用的是哪种测试框架?您确定类正确调用了安装程序吗?如果您测试pokemongederrations.objects.count()?@schwobaseggl我添加了test_pokemon_细节_view@JulienKieffer我确信调用安装程序是因为我让它打印“Created xxx Object”调试消息。这是Django的内置测试,它使用unittest if IIRC.pokemonderrations.objects.count()是1。你就是那个人!就是这样。我不认为我会找到它,除非我看了《口袋妖怪.objects.count()》/code>并看到有2个。
