Django Custom Template Tags And Filters
Django Template Tags are simple Python functions that accept a value, an optional argument, and return a value to be displayed on the page.
First, In your application folder, create a "templatetags" directory at the same level as the models and views.
You want this directory to be recognized as a Python package, so make sure you create an empty "__init__.py" file. Next, create the Python file that will hold your tags and name it something like app_tags.py.
Python Memcached Implementation for Django Project
Memcache is a memory caching system that helps web applications and mobile app backends to improve performance and scalability. We should consider using Memcache when your pages are loading too slowly or your app is having scalability issues. In This Blog Post, Let's see how to use Memcached for server-side application caching.

Handling Custom Error Pages(404, 500) In Django
404 Page not found and 500 Internal server errors generally occur in every website. When these errors occurs, generally for Django application it will load page showing the application settings.

Understanding Django Permissions And Groups
Django comes with a simple permissions system. It provides a way to assign permissions to specific users and groups of users. We can have permissions for add, edit, deleting a model.
Django’s template system comes with a wide variety of built-in tags and filters designed to address the presentation logic needs of your application. You can extend the template engine by defining custom tags and filters using Python, and then make them available to your templates using the {% load %} tag.
Custom template tags and filters must be inside a Django app. If they relate to an existing app it makes sense to create them there; otherwise, you should create a new app to hold them.
