Django templates are one of the essential and productive parts of this popular Python framework. They provide you with the ability to dynamically manage your website or application content. The Django template system is based on a very powerful template language that allows you to configure different layers of HTML based on data received from views, which is designed.
One of the major advantages of using templates is that there is a clear separation between logical business logic and data display on web pages. This means you can easily build your own HTML templates and apply data from the server to them without the business logic interfering with the templates.
The functionalities that Django provides in templates allow you to create complex templates. You can utilize features like loops, conditionals, and filters for processing and displaying your data. For example, you can display a list of data in an HTML table or only show specific items based on a condition.
Another important point regarding Django templates is the ability to create and use base templates. By using this capability, you can create a main template and then develop other pages based on it. This approach not only saves time but also makes it easier to maintain and update your site.
