将get_context_data()中的内容作为参数传递给序列化器的初始化方法。 例如,在视图中实例化序列化器时,将get_context_data()中的内容作为参数传递给序列化器的初始化方法。 classAaaList(APIView):defget_context_data(self,**kwargs): context= super().get_context_data(**kwargs) pkgs= self.request.data...

在get_context_data方法中过滤数据可以通过以下步骤实现: 首先,确保你的视图类继承自Django的通用视图类(如ListView、DetailView等),因为get_context_data方法是这些类提供的。 在你的视图类中重写get_context_data方法,并调用父类的get_context_data方法以获取默认的上下文数据。

I noticed that the generic classes CreateView and UpdateView doesn't inject the kwargs into the get_context_data() method. We can see here https://github.com/django/django/blob/stable/1.10.x/django/views/generic/edit.py#L174 that the methods get and post call get_context_data withou...
