[Django Tips] Make Deleting Easy In Admin!


Lets say we have a model as shown in some project.
from django.db import models

class Resource(models.Model):
"""
Model to hold resources for books.
"""
book = models.ForeignKey('Book')
book_type = models.IntegerField()
url = models.URLField()
This model can be registered in admin as follows.
from django.contrib import admin

from . import models

class ResourceAdmin(admin.ModelAdmin):
list_display = ('book', 'book_type', 'url')


admin.site.register(models.Resource, ResourceAdmin)
This will generate a nice admin interface to modify the data.

Now if we want to delete a record, we need to follow these steps.
  • First, we have to select that record
  • Next, we have to click on the action dropdown
  • Next, we have to select delete action
  • Next, we have to click Go button.
  • In the next page we have to confirm that we have to delete.
Just to delete a single record, we have to click 5 times. That's too many clicks for a single action.
To simplify the process, we can have simple delete button for the objects as shown. This can be achieved by writing a function which will insert delete button for every record.
from django.contrib import admin

from . import models


class ResourceAdmin(admin.ModelAdmin):
def delete(self, obj):
return '<input type="button" value="Delete" onclick="location.href=\'%s/delete/\'" />'.format(obj.pk)

delete.allow_tags = True
delete.short_description = 'Delete object'

list_display = ('book', 'book_type', 'url', 'delete')


admin.site.register(models.Book)
Now we have an admin with delete button for the records.
django-admin-delete
To delete an object, just click on delete button and then confirm to delete it. Now, we are deleting objects with just 2 clicks.
