How to Create and Use DeleteView in Django?
Hi Dev,
In this article we will cover on how to implement how to use deleteview in django. you can understand a concept of django deleteview example. This tutorial will give you simple example of how to create and use deleteview in django with example. let’s discuss about django deleteview class based views example.
Django Class based views are simpler and efficient to manage than function-based views. A function based view with tons of lines of code can be converted into a class based views comes with few lines only.
So, in this example, DeleteView 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
let's see bellow example here you will learn how to use deleteview in django.
Step 1: Create a Project
In this step, we’ll create a new django project using the django-admin. Head back to your command-line interface and run the following command:
django-admin startproject example
Step 2: Create a App
Now we'll create a single app called core to store a list of post names. We're keeping things intentionally basic. Stop the local server with Control+c and use the startapp command to create this new app.
python3 manage.py startapp core
Step 3: Update setting.py
Next, then update INSTALLED_APPS within our settings.py file to notify Django about the app.
Next, you need to add it in the settings.py file as follows:
settings.py
....
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'core',
]
Step 4: Creating the Model
In this step we will require the database model for storing article details in article table.Open the models.py file and add the following code:
core/models.pyfrom django.db import models
class Article(models.Model):
title= models.CharField(max_length=300)
content= models.TextField()
pub_date = models.DateTimeField(auto_now_add= True)
def __str__(self):
return self.title
Ok, all set. We can engender a migrations file for this change, then integrate it to our database via migrate.
python manage.py makemigrations python manage.py migrate
Step 5: Creating the Views
In this step, we need to configure our views. The ArticleDeleteView page will template and define and Article model as well as, open the views.py file and add:
core/models.pyfrom django.shortcuts import render
from django.views.generic.edit import DeleteView
from .models import *
class ArticleDeleteView(DeleteView):
model = Article
template_name = "core/article_confirm_delete.html"
success_url ="/"
Step 6: Creating the Template
Next, then with your text editor create new templates files: core/article_confirm_delete.html file and the add:
core/article_confirm_delete.html<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Profile Image</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css">
<style type="text/css">
body{
background-color: #f7fcff;
}
</style>
</head>
<body>
<div class="container mt-5 pt-5">
<div class="row d-flex justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">
<h4>How to Use DeleteView in Django? - <span class="text-primary">Tuts-Station.com</span></h4>
</div>
<div class="card-body">
<form method="post">{% csrf_token %}
<p>Are you sure you want to delete <strong>"{{ object }}"</strong>?</p>
<button type="submit" class="btn btn-danger">Confirm</button>
</form>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
Step 7: Creating URLs
In this section, we need a urls.py file within the core app however Django doesn't create one for us with the startapp command. Create core/urls.py with your text editor and within this file we'll import yet-to-be-created function for each--ArticleDeleteView Note as well that we set an optional URL name for each.
Here's what it looks like:
core/urls.pyfrom django.urls import path
from .views import ArticleDeleteView
urlpatterns = [
path('<pk>/delete/', ArticleDeleteView.as_view()),
]
Next, we require to add a URL path for our example app which can be done by importing include and setting a path for it.
example/urls.pyfrom django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('core.urls')),
]
Run the Server
In this step, we’ll run the local development server for playing with our app without deploying it to the web.
python manage.py runserver
Next, go to the http://localhost:8000/{id}/delete/ address with a web browser.
I Hope It will help you....
Happy Pythonic Coding!
