如果用户已经登录，则不显示登录表单

Question

我已使用用户创建表格进行用户注册。

class UserSignUpView(SuccessMessageMixin, FormView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'core/signup.html'
    success_message = 'Account created successfully.'

当用户已经登录时，它不应该看到注册表单

Answer 1

您可以使用基于类的视图的

dispatch()

方法来实现这些目标

from django.contrib.auth.mixins import LoginRequiredMixin

class UserSignUpView(LoginRequiredMixin, SuccessMessageMixin, FormView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'core/signup.html'
    success_message = 'Account created successfully.'

    def dispatch(self, request, *args, **kwargs):
        if self.request.user.is_authenticated:
            return redirect('home')  # Redirect to the home page or any other desired URL
        return super().dispatch(request, *args, **kwargs)
