Delete View - Function based Views Django

A Delete View is used to remove a record from the database. It is useful when users need to delete items like blog posts, products, or profiles. When using function-based Delete Views, we can:

• Fetch the record to delete from the database using its ID (or another unique field).
• Display a confirmation page (optional but recommended).
• Delete the record if confirmed.
• Redirect to another page after deletion.

Example: How to create and use Delete view

Consider a project named 'geeksforgeeks' having an app named 'geeks'. 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:

# import the standard Django Model 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:

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:

from django.urls import path # importing views from views..py from .views import delete_view urlpatterns = [ path('<id>/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:

<div class="main"> <!-- Create a Form --> <form method="POST"> <!-- Security token by Django --> {% csrf_token %} Are you want to delete this item ? <input type="submit" value="Yes" /> <a href="/">Cancel </a> </form> </div> 

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:

Now, we can implement this view as required using obj.delete() function.
