Delete view - function based view Django

Deleting a view is a view that deletes a specific instance of a table from the database （ Logic ）. It is used to delete entries in the database , for example , Delete  geeksforgeeks  Articles on . So deleting a view must display a confirmation message to the user , And the instance should be deleted automatically .Django  Provides exceptional support for deleting views , But let's examine how it is done manually through a function - based view . This article focuses on deleting views , Which involves Django Forms、Django Models And so on .  For delete view , We need a project that contains some models and multiple instances that can be deleted .

Django  Delete view —— Function based view

How to use examples to create and use delete views Explanation . Consider a person named  geeksforgeeks  Project , It has a name called  geeks  Applications for . 
After you have a project and an application , Let's create a model , We will create an instance of it from our view . stay  geeks/models.py  in ,  
#  Import standards from built-in Libraries  Django  Model
from django.db import models

#  Declare a “GeeksModel” The new model of
class GeeksModel(models.Model):

#  The model field
title = models.CharField(max_length = 200)
description = models.TextField()

#  Rename the instance of the model with the title name
def __str__(self):
return self.title
After creating this model , We need to run two commands to create a database for it . Python manage.py makemigrations
Python manage.py migrate Now let's use  shell  Create some instances of this model , Run the form  bash, Python manage.py shell Enter the following command  
>>> 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 are ready for the back end . Verify that the has been removed from http://localhost:8000/admin/geeks/geeksmodel/  Create examples


Now let's first create our delete view , stay  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):
#  Initial data dictionary with field name as key
context ={}

#  Acquired and delivered  id  Related objects
obj = get_object_or_404(GeeksModel, id = id)


if request.method =="POST":
#  Delete object
obj.delete()
#  After deleting redirection to the home page
return HttpResponseRedirect("/")

return render(request, "delete_view.html", context)
Now use  id  The regular expression of is mapped to the... Of the view  url,  stay  geeks/urls.py 
from django.urls import path

# importing views from views..py
from .views import delete_view
urlpatterns = [
path('<id>/delete', delete_view ),
]
Deleting a view template includes a simple form , Used to confirm whether the user wants to delete the instance . stay  geeks/templates/delete_view.html  in ,
<div class=&quot;main&quot;>
<!-- Create a Form -->
<form method=&quot;POST&quot;>
<!-- Security token by Django -->
{% csrf_token %}
Are you want to delete this item ?
<input type=&quot;submit&quot; value=&quot;Yes&quot; />
<a href=&quot;/&quot;>Cancel </a>
</form>
</div>
Everything is all set. , Now let's check if it works , visit http://localhost:8000/2/delete 



Let's check if the instance has been deleted , 


It can be used as needed obj.delete() Function implements this view in any way .
