Python Can'；无法登录Heroku部署的应用程序，但可以在本地登录

在我的web应用程序中，注册和登录在我使用正在开发的服务器时效果很好，但当我在Heroku上部署该网站时，效果不佳。。只有使用

createsuperuser

创建的用户才能工作

另外，注册后用户会在注册后自动登录

但是当他们注销时。。他们无法再次登录

这是我的代码：

注册视图

def signup(request):
    current_user_ip = get_client_ip(request)
    current_temp = Temp.objects.filter(created_by_ip=current_user_ip)
    current_temp.delete()
    if request.method == 'POST':
        signup_form = SignUpForm(request.POST, request.FILES)
        if signup_form.is_valid():
            signup_form.save()
            messages.info(request, "Thanks for registering. You are now logged in.")
            new_user = authenticate(username=signup_form.cleaned_data['email'],
                                    password=signup_form.cleaned_data['password1'],
                                    )
            login(request, new_user)
            return redirect('dashboard')
    else:
        signup_form = SignUpForm()

    context = {
        'signup_form': signup_form,
    }
    return render(request, 'signup.html', context)

forms.py

class EmailAuthForm(AuthenticationForm):
    def clean_username(self):
        return self.cleaned_data["username"].lower()


class SignUpForm(UserCreationForm):
    email = forms.EmailField(required=True, help_text='Must be a valid E-mail')
    user_name = forms.CharField(required=True, help_text='')
    password1 = forms.CharField(widget=forms.PasswordInput,
                                help_text='')
    password2 = forms.CharField(widget=forms.PasswordInput,
                                help_text='Password confirmation')
    avatar = forms.ImageField()

    class Meta:
        model = User
        fields = ('email', 'user_name', 'password1', 'password2', 'avatar')
        labels = {

保存

返回用户，您应该检查以确保它正确返回。我是否应该在Auth函数中返回用户？？我不明白。请解释更多（我还是Django初学者）如果您使用的是任何半高级IDE，您应该能够中断代码以检查值：）
