Exception Notifications via email in Rails

Hi Friends,

Let's first discuss about debugging a code. During development, suppose you have pushed some changes, then you need to test each and every functionality to check whether your code breaks or not, which is actually impossible. Suppose some part of your code is throwing exceptions, and you are not aware of that but the end user is facing issues because of that. So it is better to have a solution that automatically sends notifications to the developers and admin's whenever an exception comes in the code.

In rails we have a beautiful gem exception_notification that does the work for us. The documentation of the gem can be found at Exception Notifier in Rails.

Here I am explaining how to set up this in your application.

Step 1: Add the gem to your Gemfile.

gem 'exception_notification'

Step 2: Run the bundle.

Validate File Extension and Size Before Upload

Here is the example to validate the file extension and size before upload. Regular expression has been used to validate the file extension. And to validate file size, we use size property of file input i.e., img.files[0].size. Onclick event of button, validate() function is being called. First, it checks for file extensions (jpg, jpeg, png, etc) and give error message for the files having other extensions. Then, it validates the file size by calculating the file size using img.files[0].size.

Example:

<html>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
function Validate()
{
var image =document.getElementById("image").value;
if(image!='')
{

CSRF with Spring and AngularJS

In this blog, We will see how to configure CSRF protection and how to make AngularJS allowed to send information with a CSRF token to the server.

In AngularJS, $http service reads a token from a cookie which is named by default XSRF-TOKEN and sets it in HTTP header with name X-XSRF-TOKEN. Once it is configured, now spring running on server is supposed to insert token in cookie inside HTTP header. Now server can verify that the cookie matches X-XSRF-TOKEN HTTP header.

Let's see how it can be configured with Spring.

Step 1. Configure and enable CSRF.

Spring security comes with CSRF protection enabled. Please have a look of my previous blog.

Step 2. Configure Cookie in HTTP Header to enable CSRF for AngularJS

Here is the code below in your security configuration -

http.csrf()
