"AttributeError: 'NoneType' object has no attribute 'session' "在 django allauth 应用程序中覆盖 SignupF

Question

我尝试使用SignupForm覆盖实现djangoallauth应用程序，我的代码在将数据输入注册表单并保存用户时几乎可以工作，但是保存后，我重定向到一个新页面，该页面向我显示'NoneType' object has no attribute 'session'AttributeError。 我该如何解决它？

urls.py

from django.urls import path
from .views import login, logout, AllauthSignUpView
app_name = 'register'
urlpatterns = [
path('login/', login, name='login'),
path('signup/', AllauthSignUpView.as_view(), name='signup'),
path('logout/', logout, name='logout'),
]

views.py

覆盖注册视图 如下所示：

from django.shortcuts import render, HttpResponseRedirect
from .form import AllauthLoginForm, AllauthSignUpForm
from allauth.account.views import SignupView
from django.urls import reverse_lazy
class AllauthSignUpView(SignupView):
template_name = 'register/signup.html'
form_class = AllauthSignUpForm
success_url = reverse_lazy('core:home')  #Redirect to home.html
def form_valid(self, form):
# This method is called when valid form data has been POSTed.
if form.is_valid():
form.save()
form.clean()
return HttpResponseRedirect('core:home')   #Redirect to home.html
# It should return an HttpResponse.
return super().form_valid(form)
def get_context_data(self, **kwargs):
context = super(AllauthSignUpView, self).get_context_data(**kwargs)
signUpForm = AllauthSignUpForm(self.request.POST or None)
context['form'] = signUpForm
return context

form.py

覆盖注册表单 如下所示：

from allauth.account.forms import LoginForm, SignupForm
from django import forms
class AllauthSignUpForm(SignupForm):
def __init__(self, *args, **kwargs):
super(AllauthSignUpForm, self).__init__(*args, **kwargs)
self.fields['username'] = forms.CharField(
label='',
widget=forms.TextInput(
attrs={
'class': 'signup_name_inp text-right mb-4 border-top-0 border-right-0 border-left-0',
'placeholder': 'نام کاربری',
'dir': 'rtl',
}
),
)
self.fields['email'] = forms.EmailField(
label='',
widget=forms.EmailInput(
attrs={
'class': 'signup_mail_inp text-right mb-4 border-top-0 border-right-0 border-left-0',
'placeholder': 'ایمیل (اختیاری)',
'dir': 'rtl',
}
)
)
self.fields['password1'] = forms.CharField(
label='',
widget=forms.PasswordInput(
attrs={
'class': 'signup_pass_inp1 text-right mb-4 border-top-0 border-right-0 border-left-0',
'placeholder': 'کلمه عبور',
'dir': 'rtl',
}
)
)
self.fields['password2'] = forms.CharField(
label='',
widget=forms.PasswordInput(
attrs={
'class': 'signup_pass_inp2 text-right mb-4 border-top-0 border-right-0 border-left-0',
'placeholder': 'تکرار کلمه عبور',
'dir': 'rtl'
}
)
)
def save(self, request=None):
# Ensure you call the parent class's save.
# .save() returns a User object.
user = super(AllauthSignUpForm, self).save(request)
# Add your own processing here.
print(user.username)
# You must return the original result.
return user

注册.html

settings.py

ACCOUNTS_FORMS = {

Answer 1

您的代码似乎存在一些潜在问题，但可能导致您陈述问题的主要问题是您没有将request对象传递给views.py文件中的form.save()调用。

它应该看起来更像这样：

def form_valid(self, form):
# Don't do this. form_valid() only gets called on a valid form anyway
# if form.is_valid():
form.save(self.request)
# No need to call form.clean() again, especially after already saving the form
# form.clean()
return HttpResponseRedirect('core:home')   #Redirect to home.html

因此，总而言之，您似乎并没有在自定义form_valid()函数中执行任何"自定义"操作，因此最好完全删除它并仅使用父类中定义的函数。 您已经指定了success_url，因此您可以让 allauth 的form_valid()为您完成工作。
