DJango模板未找到问题

Question

Still learning Django and for some reason I have difficulty grasping some concepts especially the url / template / view mappings. Attempting to reirect a FormView to a "Complete" page I have the following:

urls.py

from django.urls import path

from .views import *

urlpatterns = [
    path('', IndexView.as_view(), name='index'),
    path('forgotid/', ForgotId.as_view(),name="forgotid"),
    path('forgotid/complete/',ForgotIdComplete.as_view(),name="forgotid_complete"),
    path('forgotpwd/', ForgotPwd.as_view(),name="forgotpwd")
]

views.py

from django.shortcuts import render
from django.views.generic import FormView, TemplateView

from .forms import LoginForm, ForgotIDForm


class IndexView(FormView):
    template_name = "login/index.html"
    form_class = LoginForm


class ForgotId(FormView):
    template_name = "login/forgotid.html"
    form_class = ForgotIDForm
    success_url = 'complete/'


class ForgotIdComplete(TemplateView):
    template_name = "login/forgotid/complete/forgotid_complete.html"

    def get(self, request):
        return render(request, self.template_name, None)


class ForgotPwd(TemplateView):
    template_name = "login/forgotpwd.html"

submitting the ForgotID form should redirect me to the success_url but I get an error stating that the template could not be found. Can someone please explain what and why I am doing this incorrectly.

The error I am receiving is:

TemplateDoesNotExist at /login/forgotid/complete/

My folder structure:

EDIT I found the issue. The template name in the ForgotIdComplete class should read: login/forgotid_complete and not login/forgotid/complete/forgotid_complete.html

Answer 1

change your success_url to this.

from django.core.urlresolvers import reverse_lazy

class ForgotId(FormView):
    template_name = "login/forgotid.html"
    form_class = ForgotIDForm
    success_url = reverse_lazy('forgotid_complete')

This error means that, django wanted to render the template from the path you provided but couldn't find it on the disk.

Go to settings.py and make sure that templates is configured to your actual templates directory.

PROJECT_DIR = os.path.realpath('.')
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [(os.path.join(PROJECT_DIR, 'templates'))],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

I found the issue. The template name in the ForgotIdComplete class should read: login/forgotid_complete and not login/forgotid/complete/forgotid_complete.html
