Question

我有一个模板，显示包含2个模型数据的表单。两个模型都包含一个名为“name”的属性。问题是，当我保存时，表单中“name”的错误值将保存为appuser模型。如何为“名称”字段中的每两个表单获取正确的值？

    class FarmCreateView(CreateView):
        template_name = 'directory/farm_registration.html'
        model = Appuser
        success_url = '/'

        def get_context_data(self, **kwargs):
            context = super(FarmCreateView, self).get_context_data(**kwargs)
            context['farm'] = FarmForm()
            context['appuser'] = FarmUserCreateForm()
            return context

        def post(self, request, *args, **kwargs):
            farm_form = FarmForm(self.request.POST)
            appuser_form = FarmUserCreateForm(self.request.POST)

            if farm_form.is_valid() and appuser_form.is_valid():
                # Save the appuser
                new_user = appuser_form.save(commit=False)
                new_user.name = appuser_form.cleaned_data.get('name') 

# ISSUE I would expect the line above to return the name from the
# appuser_form, but instead it return the name from the farm_form
                new_user.save()

                # Save the farm
                new_farm = farm_form.save(commit=False)
                new_farm.appuser = new_user; 
                new_farm.save()
                farm_form.save_m2m() # This is needed because we 
# initially save with commit=false - it's just the way django works

                # Log user in after registration
                new_user_login = authenticate(email=request.POST['email'], 
                   password=request.POST['password'])
                login(request, new_user_login)

                return HttpResponseRedirect('/')
            else:
                return render_to_response('directory/farm_registration.html', {'farm': 
                   farm_form, 'appuser': appuser_form}, 
                   context_instance=RequestContext(request))

Answer 1

在表单中使用前缀，如下所示：

context['farm'] = FarmForm(prefix="farm_form")
context['appuser'] = FarmUserCreateForm(prefix='farm_user_create')

Answer 2

检查已呈现表单中的name属性，尤其是{{ appuser.name }}和{{ farm.name }}输入元素的属性。

我猜他们是一样的，因为我认为渲染模板里面没有命名空间。因此，将有两个<input name="name" ...>元素，在POST上，一个将覆盖另一个元素。

因此，当您在post(...)方法中创建绑定表单时，可以使用相同的名称填充两个表单。您可以在运行开发服务器时打印self.request.POST的值来验证后者：您应该只看到一个name密钥。
