解决方案

索引视图位于 AdminSite 实例上。要覆盖它，您必须创建一个自定义的 AdminSite 子类（即不使用 django.contrib.admin.site 再次）：

 从django.contrib.admin导入AdminSite 
 from django.views.decorators.cache import never_cache 
 
 class MyAdminSite（AdminSite）：
 @never_cache 
 def index（self，request，extra_context = None）：
＃do stuff 
  

您可能需要参考原始方法： https://github.com/django/django/blob/1.4.1/django/contrib/admin/sites.py

然后，您创建一个此类的实例，并使用此实例，而不是 admin.site 注册你的模型。

  admin_site = MyAdminSite（）
  

然后，稍后：

 从某处导入admin_site 
 
 MyModelAdmin（ModelAdmin）：
 ... 
 
 admin_site.register（MyModel，MyModelAdmin）

I want to add an upload button to the default Django admin, as shown below:

To do so I overrode the admin/index.html template to add the button, but how can I override the admin view in order to process it?

What I want to achieve is to display a success message, or the error message, once the file is uploaded.

解决方案

The index view is on the AdminSite instance. To override it, you'll have to create a custom AdminSite subclass (i.e., not using django.contrib.admin.site anymore):

from django.contrib.admin import AdminSite
from django.views.decorators.cache import never_cache

class MyAdminSite(AdminSite):
    @never_cache
    def index(self, request, extra_context=None):
        # do stuff

You might want to reference the original method at: https://github.com/django/django/blob/1.4.1/django/contrib/admin/sites.py

Then, you create an instance of this class, and use this instance, rather than admin.site to register your models.

admin_site = MyAdminSite()

Then, later:

from somewhere import admin_site

class MyModelAdmin(ModelAdmin):
    ...

admin_site.register(MyModel, MyModelAdmin)

You can find more detail and examples at: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#adminsite-objects
