Question

错误地将用户注册到我的网站时，出现以下错误：

在/ accounts / register /中的

ValueError 视图account.views.register没有返回HttpResponse对象。它返回None。

views.py：

def register(request):
   if request.method == 'POST':
      form = RegistrationForm(request.POST)
      if form.is_valid():
          form.save()
          return redirect('/accounts')

   else:
      form = RegistrationForm()

      args = {'form': form}
      return render(request, 'accounts/reg_form.html', args)

urls.py：

urlpatterns = [
  path('', views.home, name="home"),
  path('explore/', views.explore, name='explore'),
  path('login/', LoginView.as_view(template_name='accounts/login.html'), name='login'),
  path('logout/', LogoutView.as_view(template_name='accounts/logout.html'), name='logout'),
  path('register/', views.register, name='register'),
  path('profile/', views.view_profile, name='profile'),
  path('profile/edit/', views.edit_profile, name='profile-edit'),
  path('change-password/', views.change_password, name='change_password'),
  path('reset-password/', PasswordResetView.as_view(template_name='accounts/reset_password.html'),
     name='reset-password'),
  path('reset-password/done/', PasswordResetDoneView.as_view(), name='password_reset_done'),
  path('reset-password/confirm/<uidb64>/<token>/',
     PasswordResetConfirmView.as_view(), name='password_reset_confirm'),
  path('reset-password/complete/', PasswordResetCompleteView.as_view(), name='password_reset_complete'),
]

main / urls.py：

urlpatterns = [
   path('', views.login_redirect, name='login_redirect'),
   path('admin/', admin.site.urls),
   path('accounts/', include('accounts.urls')),

  ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 1

您应将最后两行移回一级。

\documentclass{ociamthesis}

\colorlet{chaptergrey}{red}

\begin{document}

\chapter{text}

text

\end{document}

Answer 2

您的退货应退后四格，这意味着退货不应处于else条件下。

从以下更改views.py：

else:
  form = RegistrationForm()

  args = {'form': form}
  return render(request, 'accounts/reg_form.html', args)

对此：

else:
  form = RegistrationForm()

  args = {'form': form}
return render(request, 'accounts/reg_form.html', args)

Answer 3

由于案件表格无效，您不会返回任何内容。

def register(request):
   if request.method == 'POST':
      form = RegistrationForm(request.POST)
      if form.is_valid():
          form.save()
          return redirect('/accounts')
      else: #new
          return render(request, 'accounts/reg_form.html',  {'errors':form.errors})#new

   else:
      form = RegistrationForm()

      args = {'form': form}
      return render(request, 'accounts/reg_form.html', args)

它将重定向到account / reg_form.html，其中包含通过表单生成的错误

没有返回HttpResponse对象。它返回None
