What is Jinja pattern in Django?

Jinja supports extensions that can add extra filters, tests, globals or even extend the parser . The main motivation of extensions is to move often used code into a reusable class like adding support for internationalization.

Django is a MVC based web framework. It tells you how to organize and write your application. Jinja (Jinja2 ) is a template library. This means that you use Jinja to write the structure of your webpages.

Why do we need Jinja 2? Sandboxed Execution: It provides a protected framework for automation of testing programs , whose behaviour is unknown and must be investigated. HTML Escaping: Jinja 2 has a powerful automatic HTML Escaping, which helps preventing Cross-site Scripting (XSS Attack).

Flask comes packaged with the powerful Jinja templating language . For those who have not been exposed to a templating language before, such languages essentially contain variables as well as some programming logic, which when evaluated (or rendered into HTML) are replaced with actual values.

Jinja is a Python templating engine, aimed at helping you to do dynamic things with your HTML like passing variables, running simple logic, and more ! With Jinja, you will notice we are using {% %} , this denotes logic. For variables, you will see {%{% }} .

Like Django template loaders, Jinja also offers the ability to create custom template loader , in addition to using built-in Jinja template loaders similar to those offered by Django template (e.g. loading templates from a Python dictionary).

Create jinja2.py file in your project folder . This is required to modify the default jinja2 Environment (in our case, passing some additional global variables). 2. Add jinja2 backend to django project settings file, including our modified environment.
