You can add custom actions to perform batch operations on selected objects in Django Admin. Define a method in your admin class and decorate it with @admin.action to register it as an action.
Example code:
# admin.py
from django.contrib import admin
from .models import MyModel
class MyModelAdmin(admin.ModelAdmin):
actions = ['custom_action']
def custom_action(self, request, queryset):
# Perform your custom action here
for obj in queryset:
# Do something with each selected object
obj.some_field = True
obj.save()
custom_action.short_description = 'Activate selected objects'
admin.site.register(MyModel, MyModelAdmin)
