我正在使用Django parler来翻译我的模型。现在我正在创建一个自定义的管理面板，我有一个创建和更新内容的视图。我正在使用一个基于类的视图，继承自“视图”的创建和更新视图，所以我不能使用TranslatableCreateView和TranslatableUpdateView。我在Django parler的代码中看到，使用TranslatableModelFormMixin，你可以添加翻译支持到基于类的视图。我使用了这个mixin，但仍然无法访问语言选项卡。
这里是Views.py:

class ContentCreateUpdateView(TranslatableModelFormMixin, TemplateResponseMixin, View):
module = None
model = None
obj = None
template_name = 'content-form.html'

def get_model(self, model_name):
    if model_name in ['text', 'video', 'image', 'file']:
        return apps.get_model(app_label='courses', model_name=model_name)
    return None

def get_form(self, model, *args, **kwargs):
    Form = modelform_factory(model, exclude=['owner',
                                             'order',
                                             'created',
                                             'updated'])
    return Form(*args, **kwargs)

def dispatch(self, request, module_id, model_name, id=None):
    self.module = get_object_or_404(Module, id=module_id, course__owner=request.user)
    self.model = self.get_model(model_name)
    if id:
        self.obj = get_object_or_404(self.model,
                                     id=id,
                                     owner=request.user)
    return super().dispatch(request, module_id, model_name, id)

def get(self, request, module_id, model_name, id=None):
    form = self.get_form(self.model, instance=self.obj,)
    return self.render_to_response({'form': form, 'object': self.obj})

def post(self, request, module_id, model_name, id=None):
    form = self.get_form(self.model, instance=self.obj, data=request.POST, files=request.FILES)
    if form.is_valid():
        obj = form.save(commit=False)
        obj.owner = request.user
        obj.save()
        if not id:
            # new content
            Content.objects.create(module=self.module, item=obj)
        return redirect('module_content_list', self.module.id)
    return self.render_to_response({'form': form, 'object': self.obj})

下面是django parler的源代码：

class TranslatableModelFormMixin(LanguageChoiceMixin):
"""
Mixin to add translation support to class based views.

    Return a ``TranslatableModelForm`` by default if no form_class is set.

选项卡应如下所示：
