The default “delete selected” admin action in Django

Question

How can I remove or change the verbose name of the default admin action \"delete selected X item\" in the Django admin panel?

Answer 1

Not sure if this sort of monkey-patching is a good idea, but shoving this in one of my admin.py works for me:

from django.contrib.admin.actions import delete_selected
delete_selected.short_description = u'How\'s this for a name?'

This will change the verbose name for all your admin sites. If you want to change it just for one particular model's admin, I think you'll need to write a custom admin action.

Tested with Django version 1.1:

>>> import django
>>> django.VERSION
(1, 1, 0, 'beta', 1)

Answer 3

Alternatively to Googol's solution, and by waiting for delete_model() to be implemented in current Django version , I suggest the following code.

It disables the default delete action for current AdminForm only.

class FlowAdmin(admin.ModelAdmin):
    actions = ['delete_model']

    def get_actions(self, request):
        actions = super(MyModelAdmin, self).get_actions(request)
        del actions['delete_selected']
        return actions

    def delete_model(self, request, obj):
        for o in obj.all():
            o.delete()
    delete_model.short_description = 'Delete flow'

admin.site.register(Flow, FlowAdmin)

You can disable the action from appearing with this code.

from django.contrib import admin
admin.site.disable_action('delete_selected')

If you chose, you could then restore it on individual models with this:

class FooAdmin(admin.ModelAdmin):
    actions = ['my_action', 'my_other_action', admin.actions.delete_selected]

from django.contrib.admin import sites
from django.contrib.admin.actions import delete_selected


class AdminSite(sites.AdminSite):
    """
    Represents the administration, where only authorized users have access.
    """
    def __init__(self, *args, **kwargs):
        super(AdminSite, self).__init__(*args, **kwargs)
        self.disable_action('delete_selected')
        self.add_action(self._delete_selected, 'delete_selected')

    @staticmethod
    def _delete_selected(modeladmin, request, queryset):
        _delete_qs = queryset.delete

        def delete():
            for obj in queryset:
                modeladmin.delete_model(request, obj)
            _delete_qs()

        queryset.delete = delete
        return delete_selected(modeladmin, request, queryset)

Answer 6

class FooAdmin(sites.AdminSite):
        not_deleted = ['value1', 'value2']
        actions = ['delete_selected_values']

    def delete_selected_values(self, request, queryset):
        # my custom logic
        exist = queryset.filter(value__in=self.not_deleted).exists()
        if exist:
            error_message = "Error"
            self.message_user(request, error_message, level=messages.ERROR)
        else:
            delete_action = super().get_action('delete_selected')[0]
            return delete_action(self, request, queryset)
    delete_selected_values.short_description = 'delete selected'

admin.site.register(Foo, FooAdmin)
