Question

我被告知这段代码在django中有效。

class UserDetailView(LoginRequiredMixin, DetailView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'

因为我是Django的新手。此视图方法没有返回render_to_response或任何形式的HttpResponse值。

附件是views.py

# -*- coding: utf-8 -*-
from __future__ import absolute_import, unicode_literals

from django.core.urlresolvers import reverse
from django.views.generic import DetailView, ListView, RedirectView, UpdateView

from django.contrib.auth.mixins import LoginRequiredMixin

from .models import User


class UserDetailView(LoginRequiredMixin, DetailView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'


class UserRedirectView(LoginRequiredMixin, RedirectView):
    permanent = False

    def get_redirect_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})


class UserUpdateView(LoginRequiredMixin, UpdateView):

    fields = ['name', ]

    # we already imported User in the view code above, remember?
    model = User

    # send the user back to their own page after a successful update
    def get_success_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})

    def get_object(self):
        # Only get the User record for the user making the request
        return User.objects.get(username=self.request.user.username)


class UserListView(LoginRequiredMixin, ListView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'

这些视图如何返回哪个网址没有返回语句

Answer 1

您正在使用通用视图（https://docs.djangoproject.com/es/1.9/ref/class-based-views/generic-display/）。您的视图是DetailView的子视图。看看文档，你就会把事情搞清楚。

Userview没有return语句
