How to copy a model object in Django?

Question

Django

Good afternoon!
Tell me how you can implement copying / cloning of a Django model object in the Admin panel?
Maybe somehow you can add an action to the context menu where "Delete selected objects" ..??

Answer 1

everything is in the official documentation https://docs.djangoproject.com/en/2.2/ref/contrib/...

Answer 2

Yes. Very simple:
Here is my example:

def dublicate_ad(modeladmin, request, queryset):
    #клонирование выбранных Ad
    for ad in queryset:
        ad.pk = None
        ad.save()

dublicate_ad.short_description = "Дублировать объект"    

@admin.register(Ad)
class AdAdmin(admin.ModelAdmin):
    actions = [dublicate_ad]
