How to add authentication to Django Website?
In a web application, there are two key elements to data management. The first is to save data acquired from multiple browser queries, and the second is to use this preserved data to authenticate users. Sessions allow us to keep track of data across numerous browser queries. The second half of the equation is logging in users using those sessions. We cannot trust people to be who they claim they are, so we have to verify their identities along the process. Django, of course, includes tools to perform these and other typical tasks. User accounts, groups, permissions, and cookie-based user ...

Read MoreHow to use memcached in Django?
The fact that dynamic websites provide an interactive and adaptable website is their calculations, including database queries, template rendering, and business logic, to produce the page that your site's visitor sees.

Saving the result of a time-consuming calculation so that you don't have to do it again is referred to as caching. The caching mechanism requires very ...

Phishing is another term for this. We will look at a common case because this type of attack can take many different shapes and has nearly unlimited variations. Let us consider simple ...

Read MoreHow to add validation to your Django project?
Validation is the process through which the computer automatically checks to ensure that the data entered is sensible and reasonable. It does not provide if the data entered is accurate or not.
