Question

我对某些单元测试有一个奇怪的问题，这很简单，但都失败了。奇怪的是，这与runserver一起工作，即我可以渲染perfil_usuario视图，但在单元测试中，这与NoReverseMatch失败。

首先，这是我的主要urlconf：

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r"^$", include("traxx.hotsite.urls", namespace="hotsite")),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^imperavi/', include('imperavi.urls')),
    url(r"^app/", include("traxx.sistema.urls", namespace="app")),
    url(r"^usuarios/", include("traxx.usuarios.urls", namespace="usuarios")),
    url(r"^notificacoes/", include("traxx.notificacoes.urls", namespace="notificacoes")),
    url(r"^clientes/", include("traxx.clientes.urls", namespace="clientes")),
)

我的usuarios（主要的第4个url conf）urlconf如下：

# coding: utf-8
from django.conf.urls import patterns, include, url

urlpatterns = patterns("traxx.usuarios.views",
                       url(r"^perfil/(?P<id>\d+)/$", "perfil_usuario", name="perfil"),
                       url(r"^configuracoes/(?P<id>\d+)/$", "configuracoes_usuario", name="configuracoes"),
                       url(r"^login/$", "login", name="login"),
                       url(r"^logout/$", "logout", name="logout"),
)

这是观点：

def perfil_usuario(request, id):
    usuario = get_object_or_404(Usuario, pk=id)
    return render(request, "usuarios/perfil_usuario.html", {"usuario": usuario})

这是失败的单元测试：

class PerfilUsuarioViewTestCase(TransactionTestCase):

    """Testes para a view home"""

    def setUp(self):

        pass

    def test_get_perfil_usuario(self):

        usuario_fake = mommy.make(Usuario, nome_usuario="teste")

        c = Client()
        resposta = c.get(reverse("usuarios:perfil", kwargs={"id": usuario_fake.pk}))

        self.assertEqual(200, resposta.status_code)

反向调用反向（＆＃34; usuarios：perfil＆＃34;，kwargs = {＆＃34; id＆＃34;：usuario_fake.pk}）工作正常，输出/ usuarios / perfil / 1 /。 / p>

Answer 1

从回溯中可以看出，id中传递的kwargs被评估为None。这就是它与usuarios/perfil/(?P<id>\\d+)/$ url模式不匹配的原因。

换句话说，usuario_fake.pk值为None。

UPD：

问题实际上是在回溯抱怨的模板中。

django测试客户端失败，但url工作
