Delete View Function based Views Django (original) (raw)

Last Updated : 28 Apr, 2025

Delete View refers to a view (logic) to delete a particular instance of a table from the database. It is used to delete entries in the database for example, deleting an article at geeksforgeeks. So Delete view must show a confirmation message to the user and should delete the instance automatically. Django provides extra-ordinary support for Delete Views but let's check how it is done manually through a function-based view. This article revolves around Delete View which involves concepts such as Django Forms, Django Models.

For Delete View, we need a project with some models and multiple instances that we can use for deleting.

Django Delete View - Function Based Views

Illustration of How to create and use Delete view using an Example. Consider a project named geeksforgeeks having an app named geeks.

Refer to the following articles to check how to create a project and an app in Django.

• How to Create a Basic Project using MVT in Django?
• How to Create an App in Django ?

After you have a project and an app, let's create a model of which we will be creating instances through our view. In geeks/models.py,

Python3 `

import the standard Django Model

from built-in library

from django.db import models

declare a new model with a name "GeeksModel"

class GeeksModel(models.Model):

# fields of the model
title = models.CharField(max_length = 200)
description = models.TextField()

# renames the instances of the model
# with their title name
def __str__(self):
    return self.title

`

After creating this model, we need to run two commands in order to create Database for the same.

Python manage.py makemigrations Python manage.py migrate

Now let's create some instances of this model using shell, run form bash,

Python manage.py shell

Enter following commands

from geeks.models import GeeksModel GeeksModel.objects.create( title="title1", description="description1").save() GeeksModel.objects.create( title="title2", description="description2").save() GeeksModel.objects.create( title="title2", description="description2").save()

Now we have everything ready for back end. Verify that instances have been created from http://localhost:8000/admin/geeks/geeksmodel/

Now let's create our delete view first, In geeks/views.py

Python3 `

from django.shortcuts import (get_object_or_404, render, HttpResponseRedirect)

from .models import GeeksModel

delete view for details

def delete_view(request, id): # dictionary for initial data with # field names as keys context ={}

# fetch the object related to passed id
obj = get_object_or_404(GeeksModel, id = id)


if request.method =="POST":
    # delete object
    obj.delete()
    # after deleting redirect to 
    # home page
    return HttpResponseRedirect("/")

return render(request, "delete_view.html", context)

`

Now a url mapping to this view with a regular expression of id,
In geeks/urls.py

Python3 `

from django.urls import path

importing views from views..py

from .views import delete_view urlpatterns = [ path('/delete', delete_view ), ]

`

Template for delete view includes a simple form confirming whether user wants to delete the instance or not. In geeks/templates/delete_view.html,

HTML `

`

Everything ready, now let's check if it is working or not, visit http://localhost:8000/2/delete

Let's check if instance has been deleted or not,

One can implement this view in any manner as per requirement using obj.delete() function.
