Question

假设我的表格如下：

SUBSCRIBE

现在我想在基于类的视图中获取表单：

Class FormCreateView（CreateView）：型号=用户

class FormA(models.ModelForm):
    ...
class FormB(models.ModelForm):
  ....
class FormC(models.ModelForm):
 .....

所以我已经这样做了。但是表单没有被提交，它给我输入错误：

    def post(self, request, *args, **kwargs):
        if self.request.user.user_level == 1:
             get FormA
        if self.request.user.user_level == 2:
             get FormB
        if self.request.user.user_level == 3:
             get Formc
        return reverse('xyz')

我的class UserCreateView(CreateView): model = User # form_class = UserCreationForm template_name = "users/create_user.html" success_url= "/users/create" def get_form_class(self): if self.request.user.user_level == 1 or self.request.user.user_level == 10: # form_class = UserCreationForm return UserCreationForm elif self.request.user.user_level == 20: # form_class = UserCreationFormCompanyManager return UserCreationFormCompanyManager else: # form_class = UserCreationFormHomeManager return UserCreationFormHomeManager def post(self, request, *args, **kwargs): form = self.get_form_class() user_level = User.objects.get(id=request.user.id) # form = UserCreationFormHomeManager(request.POST) # if request.method=='POST': # form = UserCreationFormCompanyManager(request.POST) if user_level == 20: if form.is_valid(): obj = form.save(commit=False) obj.company = self.request.user.company # obj.password = make_password(form.cleaned_data['password']) print(obj) obj.save() return obj elif user_level == 30: # if request.method=='POST': # form = UserCreationFormHomeManager(request.POST) if form.is_valid(): obj = form.save(commit=False) obj.company = self.request.user.company obj.home = self.request.user.home # obj.password = make_password(form.cleaned_data['password']) print(obj) obj.save() return obj else: # if request.method=='POST': # form = UserCreationFormHomeManager(request.POST) if form.is_valid(): # obj.password = make_password(form.cleaned_data['password']) print(obj) obj = form.save() return obj return HttpResponseRedirect(reverse('users:create-user'))中有这三种形式。当我尝试通过form.py调用表单（即已注释的一个）方法表单时，未保存该表单。

您可以在get_form_class方法中使用选择表单：

def get_form_class(self):
    if self.request.user.user_level == 1:
         return FormA
    elif self.request.user.user_level == 2:
         return FormB
    elif self.request.user.user_level == 3:
         return FormC
    else:
         return DefaultForm

根据条件在基于Django类的视图中获取不同的表单
