We are having many image cropping plugins developed in jquery that are being used to crop an image. Jcrop is one of the plugins developed in Jquery.
Coveraslls will check the code coverage for your test cases. To use coveralls.io your code must be hosted on GitHub or BitBucket.

Here we learn how to redirect a www to non-www or vice-versa also we see how to redirect pages. We will see differences between 301 and 302 redirection.
Using the Inbound parse webhook, we can parse the contents, attachments of an incoming email.
Inbound Parse API follows 3 steps:
1. sending an email to the mail id(URL_Name@your specified domain/sub domain.com)
a Here the domain/ sub domain, where the emails will be sent, and the URL_Name, where we will handle the contents, attachments of an incoming email in our app.
b. Here the domain/sub domain should point out the MX record to mx.sendgrid.net.
Django by default provides automatic admin interface, that reads metadata from your models to provide a beautiful model interface where trusted users can manage content on your site. With this interface we can perform actions like delete, filter and other. In this blog post we learn to add new actions to the admin dashboard and how to disable built in actions of the admin dashboard.
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. So to avoid settings open, we'll keep DEBUG=False in production mode. But keeping DEBUG=False by default the pages will be served by webservers like nginx or apache which won't look good for an end user point of view.
In 1994, FHS(File System Hierarchy Standard) was proposed, it describes the directory structure of UNIX and UNIX-like systems(Linux). Before FHS was proposed, there had been UNIX-like operating systems which had their own standards. Today almost every UNIX-like systems notable Linux distros follow these guidelines.
Django's haystack provides autocomplete functionality. To do autocomplete effectively, the search backend(elasticsearch in this case) uses n-grams (essentially a small window passed over the string). Because this alters the way your data needs to be stored. We had two choices: NgramField and EdgeNgramField used as n-grams in search backend. The major drawback of the n-grams is that they take minimum of 3 letters in the search query.
