Build a Django Application to Perform CRUD Operations

This project provides a comprehensive system for managing recipe data, including the ability to create, view, edit, and delete recipes. It demonstrates the fundamental operations of a CRUD application for recipe management using Django, typically used in web applications for organizing and maintaining recipe collections.

CRUD Operations In Django

the "Recipe Update" project is a part of a CRUD (Create, Read, Update, Delete) application for managing recipes. Here's a summary of its key functionality:

• Create: The project enables users to create new recipes by providing a name, description, and an image upload.
• Read: Users can view a list of recipes with details, including names, descriptions, and images. They can also search for recipes using a search form.
• Update: Users can update existing recipes by editing their names, descriptions, or images. This functionality is provided through a form that populates with the recipe's current details.
• Delete: The project allows users to delete recipes by clicking a "Delete" button associated with each recipe entry in the list.

CRUD operations are fundamental to any Django project. To fully master Django's potential and handle more complex operations, the Django Web Development - Basics to Advance is a comprehensive course that can take your skills to the next level.

Create Django Project and App

Prerequisites:

• Django Introduction and Installation
• Creating a Project

Create the project:

django-admin startproject core
cd core

Create the app inside the project:

python manage.py startapp recipe

Configure settings.py

setting.py: After creating the app we need to register it in settings.py in the installed_apps section like below

INSTALLED_APPS = [
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
"recipe",
]

Create Recipe Model

recipe/models.py: The code defines a Django model named Recipe that represents recipes. It includes fields for the user who created the recipe, the recipe's name, description, image, and the number of times the recipe has been viewed. The user field is linked to the built-in User model and can be null, allowing for recipes without a specific user.

Create Views

recipe/views.py: The code is part of a Django web application for managing recipes. It includes functions for:

1. Displaying and creating recipes, with the ability to filter recipes by name.
2. Deleting a specific recipe.
3. Updating an existing recipe, including the option to change the recipe's image.

These functions are responsible for various recipe-related actions in the application.

Register Model in Admin

recipe/admin.py: We register the models in admin.py file

Create Templates

recipes.html: First we created the receipes.html file this Django template code is a part of a web page for adding, searching, displaying, updating, and deleting recipes. Here's a simplified explanation.

update_recipe.html: This template provides a user-friendly interface for editing the details of a recipe, including its name, description, and image. When a user submits the form, it likely sends the updated data to a Django view for processing and updating the database record.

base.html: It is the base HTML file which is extended by all other HTML files.

urls.py: Setting up all the paths for our function.

Create and Run Migrations

Run these commands to apply the migrations:

python manage.py makemigrations
python manage.py migrate

Run the Development Server

Run the server with the help of following command:

python manage.py runserver

Output:
