这是我的文件：
from django.shortcuts import render
from django.urls import reverse_lazy
from . import forms
from django.views.generic import CreateView
from django.views.generic import TemplateView
class SignUp(CreateView):
form_class = forms.UserCreateForm
success_url = reverse_lazy("login")
template_name = "webportal/signup.html"
class HelloPage(TemplateView):
template_name = "hello.html"
2.apps urls.py：
from django.urls import path
from django.contrib.auth import views as auth_views
from . import views
app_name = "webportal"
urlpatterns = [
path("logout/", auth_views.LogoutView.as_view(), name="logout"),
path("", views.SignUp.as_view(), name="signup"),
path(
"login/",
auth_views.LoginView.as_view(template_name="webportal/login.html"),
name="login",
),
]
3.models.py：
from django.db import models
from django.contrib import auth
class User(auth.models.User, auth.models.PermissionsMixin):
""" this is account User model"""
def __str__(self):
return "@{}".format(self.username)
4.forms.py：
from django.db import models
from django.contrib import auth
class User(auth.models.User, auth.models.PermissionsMixin):
""" this is account User model"""
def __str__(self):
return "@{}".format(self.username)
5.templates-> webportal（myapp的名称）-> 1.login.html，
{% extends "base.html" %} {% load bootstrap3 %} {% block content %}
<div class="container">
<h1>Login In</h1>
<form method="POST">
{% csrf_token %} {% bootstrap_form form %}
<input type="submit" value="Login" class="btn btn-default" />
</form>
</div>
{% endblock content %}
2.signup.html
{% extends "base.html" %} {% load bootstrap3 %} {% block content %}
<div class="container">
<h1>Sign Up</h1>
<form method="POST" action="{% url 'webportal:login' %}">
{% csrf_token %}{% bootstrap_form form %}
<input type="submit" value="Sign Up" class="btn btn-default" />
</form>
</div>
{% endblock content %}
<!-- -->
6.project的urls.py：
from django.contrib import admin
from django.urls import path, include
from rest_framework.authtoken.views import obtain_auth_token
from django.contrib.staticfiles.urls import static
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from django.conf import settings
from . import views
from . import settings
urlpatterns = [
path("", views.HomePage.as_view(), name="home"),
path("admin/", admin.site.urls),
path("hello/", views.HelloPage.as_view(), name="hello"),
path("thanks/", views.Thankspage.as_view(), name="thanks"),
path("core/", include("core.urls", namespace="core")),
path("webportal/", include("django.contrib.auth.urls")),
path("webportal/", include("webportal.urls", namespace="webportal")),
]
urlpatterns += staticfiles_urlpatterns()
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
实际上，我有我的自定义登录模板，因此，在应用程序的urls.py中，我已在as_view方法中相应地传递了参数template_name。我不知道为什么django引擎搜索registration / login.html ..
我的错误：
