Question

我使用html格式创建登录页面：在这里，我想将用户注册为管理员。但是当我提交注册表时，它什么都没有显示（空白页）

<form  action="" method="post" enctype="multipart/form-data">
    {% csrf_token %} 
    {% include 'music/form-template.html' %}
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-8">
        <button type="submit" class="btn-success">Register</button>
         </div>
        </div>
     </form>

和forms.py：

from django.contrib.auth.models import User
from django import forms

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ['username', 'email', 'password']

这是url.py

from django.urls import re_path, path
from . import views
app_name = 'music'
urlpatterns=[
    re_path(r'^$',views.IndexView.as_view(), name='index'),
    path(r'register/',views.UserFormView.as_view(), name='register'),
    re_path(r'^(?P<pk>[0-9]+)/$',views.DetailView.as_view(),name='details'),
    path(r'album/add/', views.AlbumCreate.as_view(), name='album-add'),
    re_path(r'album/(?P<pk>[0-9]+)/$', views.AlbumUpdate.as_view(),name='album-update'),
    re_path(r'album/(?P<pk>[0-9]+)/delete/$', views.AlbumDelete.as_view(),name='album-delete'),
    ]

这是主要的url.py：

from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
from django.urls import include,path
from django.conf import settings


urlpatterns = [
    path('admin/', admin.site.urls),
    path('music/',include('music.urls')),
] 


if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL,document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

当然还有views.py：

from django.views.generic.edit import CreateView, UpdateView, DeleteView
from django.views import generic
from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login
from django.urls import reverse_lazy
from django.views.generic import View
from .forms import UserForm
from .models import Album


class IndexView(generic.ListView):
    template_name = 'music/index.html'
    context_object_name = 'all_album'

    def get_queryset(self):
        return Album.objects.all()

class DetailView(generic.DetailView):
    model = Album
    template_name = 'music/details.html'

class AlbumCreate(CreateView):
    model = Album
    fields = ['artist', 'album_title', 'genre', 'album_logo']

class AlbumUpdate(UpdateView):
    model = Album
    fields = ['artist', 'album_title', 'genre', 'album_logo']

class AlbumDelete(DeleteView):
    model = Album
    success_url = reverse_lazy('music:index')

class UserFormView(View):
    form_class = UserForm
    template_name = 'music/registration_form.html'

    # display blank form
    def get(self, request):
        form = self.form_class(None)
        return render(request,self.template_name, {'form':form})

    # process form data
    def post(self, request):
        form = self.form_class(request.POST)

        if form.is_valid():

            user = form.save(commit=False)

            # cleaned (normalized) data
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            user.set_password(password)
            user.save()


            # returns user objects if credentials are correct
            user = authenticate(username=username, password= password)

            if user is not None:

                if user.is_active():
                    login(request, user)
                    return redirect('music:index')

        return render(request,self.template_name, {'form':form})

但提交表单后应该出现错误：

 Method Not Allowed (POST): /music/register/
 [26/Mar/2018 19:07:58] "POST /music/register/ HTTP/1.1" 405 0

因为我刚接触Django所以我不太了解错误处理。

请帮我解决问题。谢谢

Answer 1

您已将视图调用为UserFormView，但它实际上并不是表单视图;它只是一个标准的视图，它不知道如何处理POST。

您应该像其他视图那样继承CreateView或UpdateView。

Django 2.0方法不允许（POST）
