How can I use mixins in Django admin?

You can use mixins in Django admin to add reusable functionality to your admin classes. For example, you can create a mixin that adds custom actions or filters.

Can you give me an example of a mixin for custom actions?

Sure! Here's a simple mixin that adds a custom action to delete selected objects:

class CustomDeleteMixin:
    def delete_selected(self, request, queryset):
        # Custom delete logic here
        pass

How do I integrate this mixin into my admin class?

You can integrate it by inheriting from the mixin in your admin class like this:

class MyModelAdmin(CustomDeleteMixin, admin.ModelAdmin):
    actions = ['delete_selected']

What if I want to add a custom filter instead?

You can create a filter mixin similarly. Just define a method for the filter and add it to your admin class. Let me know if you need a specific example!
