我正在扩展change_list.html，我需要输出settings.py

中定义的变量

如何将该特定变量传递到自定义管理模板上下文？

Answer 1

class MyModelAdmin(admin.ModelAdmin):
    ...
    def changelist_view(self, request, extra_context=None):
        extra_context = extra_context or {}
        extra_context['some_var'] = 'This is what I want to show'
        return super(MyModelAdmin, self).changelist_view(request, extra_context=extra_context)
