Django Views

In Django, views are the backbone of handling user requests and rendering responses. There are two primary paradigms for implementing views: Function Based Views (FBVs) and Class Based Views (CBVs). Function Based Views offer simplicity and directness, allowing developers to define views as Python functions. Within this paradigm, common functionalities like creating, listing, displaying details, updating, and deleting objects are implemented as separate functions.

While both paradigms have their merits, the choice between FBVs and CBVs ultimately depends on factors such as project requirements, development preferences, and scalability concerns.

• Function Based Views
  • Create View
  • List View
  • Detail View
  • Update View
  • Delete View
• Class Based Generic Views Django
  • Createview
  • ListView
  • DetailView
  • UpdateView
  • DeleteView
  • FormView
• Class Based vs Function Based Views

Django URLs

In Django, URL patterns serve as a crucial mechanism for directing incoming requests to the appropriate views within your web application. With the flexibility of regular expressions, Django’s URL dispatcher allows you to define patterns that match specific URL patterns and route them to corresponding views. When dealing with GET parameters passed through URLs in Django, accessing these parameters within views is straightforward, enabling efficient handling of user inputs and customization of responses.

• Django URL patterns
• Get parameters passed by urls in Django
• URL Validator in Django
• URL Shortener with Django
• Django URLResolver error

Django Templates

In Django, URLs play a crucial role in navigating through different views and templates within your web application. When working with Django templates, several key concepts enhance the flexibility and functionality of your frontend. Template filters allow you to manipulate variables displayed in your templates, enabling transformations like date formatting or string manipulation.

• Template Filters
• Template Tags
• variables
• Boolean Operators
• for loop
• if – Django Templates
• Template Inheritance

Django Models

Models serve as the backbone of database operations, facilitating seamless management of data. This guide delves into various aspects of Django Models, starting from the fundamental operations of inserting, updating, and deleting data using the Object-Relational Mapping (ORM) provided by Django.

Here, You’ll learn how to create a basic app model, initialize migrations, and execute them to synchronize your database schema. Moreover, we delve into built-in field validations, ensuring data integrity and consistency, while also delving into the customization of these validations to suit specific application requirements.

• model data types and fields list
• Add the slug field inside Django Model
• Intermediate fields in Django

• Built-in Field Validations – Django Models
• Custom Field Validations in Django Models
• How to use Django Field Choices ?
• Overriding the save method – Django

Django Forms

To start, you can create a form using Django Forms by defining a class that inherits from Django’s forms.Form class. Within this class, you can specify the fields you want to include in your form using various field types provided by Django, such as CharField, IntegerField, EmailField, etc. Once you’ve defined your form, you can render HTML forms in Django using both GET and POST methods. Django’s built-in template tags and filters make it easy to render forms in your HTML templates while ensuring security and CSRF protection.

Django Forms offer a wide range of field types to cater to different data types and validation requirements. Additionally, you can customize the appearance and behavior of form fields by using form field custom widgets, allowing you to enhance user experience and tailor forms to your specific needs.
