如何在DetailView中向上下文对象添加数据?

问题描述

我需要在Django中编写一个DetailView.我实现了此功能.但是，我需要与上下文对象一起添加更多数据.我将如何实现这一目标.

I need to write a DetailView in Django. I achieved this functionality. However, I need to add some more data along with the context object. How will I achieve this.

我的通用视图是:

class AppDetailsView(generic.DetailView):
    model = Application
    template_name = 'appstore/pages/app.html'
    context_object_name = 'app'

我需要再向上下文对象添加一个变量:

I need to add one more variable to the context object:

response = list_categories(storeId)

推荐答案

如何使用get_context_data

How about using get_context_data

class AppDetailsView(generic.DetailView):
     model = Application
     def get_context_data(self, **kwargs):
        context = super(AppDetailsView, self).get_context_data(**kwargs)
        context['categories'] = list_categories(storeId)
        return context
