/accounts/signup/View.__init__() 处的类型错误采用 1 个位置参数，但给出了 2 个

Question

我正在使用 Django allauth 对用户进行身份验证以进行注册和登录。但是当我尝试访问 django allauth 注册和登录模板时出现此错误 TypeError at /accounts/signup/ View.__init__() takes 1 positional argument but 2 were given。

urls.py:

from django.urls import path
from allauth.account import views as allauthViews
from . import views



urlpatterns = [
    path("", views.index, name="index"),
    path("<int:myid>/", views.quiz, name="quiz"), 
    path('<int:myid>/data/', views.quiz_data_view, name='quiz-data'),
    path('<int:myid>/save/', views.save_quiz_view, name='quiz-save'),
    
    path("accounts/signup/", allauthViews.SignupView, name="account_signup"),
    path("accounts/login/", allauthViews.LoginView, name="account_login"),
    path("accounts/logout/", allauthViews.LogoutView, name="account_logout"),
    
    path('add_quiz/', views.add_quiz, name='add_quiz'),    
    path('add_question/', views.add_question, name='add_question'),  
    path('add_options/<int:myid>/', views.add_options, name='add_options'), 
    path('results/', views.results, name='results'),    
    path('delete_question/<int:myid>/', views.delete_question, name='delete_question'),  
    path('delete_result/<int:myid>/', views.delete_result, name='delete_result'),

您需要在网址中使用 as_view()

…
urlpatterns = [
    …
    path("accounts/signup/", allauthViews.SignupView.as_view(), name="account_signup"),
    path("accounts/login/", allauthViews.LoginView.as_view(), name="account_login"),
    path("accounts/logout/", allauthViews.LogoutView.as_view(), name="account_logout"),
    … 
]
