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.

7 Strange Factors That Influence Online Conversions

Don’t utilize periods in your headlines:-

Tests have shown that being grammatically right in your headlines and sub-features is not useful. Utilizing periods and commas really reduces the quantity of conversions. Finishing your headlines and sub-headers with a period can bring about the reader to quit perusing and proceed onward to something else entirely.

Include a telephone number-even the fact that they won't call it:-

Having a valid telephone number on your website gives potential clients a feeling of trust. Realizing that, if they needed to, they could connect and speak a live individual does a great deal to impact a person’s choice about purchasing an product online. Very few people will really call the number, however just seeing it there on your site manufactures their confidence.

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()

Difference between High Level and Low Level Testing & their advantages

Difference between High level testing and Low level testing:-

High Level Test Cases:- These test cases define the functionality of a software/product in a broader way without going into deep functionality. Like if we have to write high level test cases for login functionality we'll test that 'User should be able to login success full with valid credentials'.

Advantages :-Its advantage is that a tester is not bound to follow the test cases step by step and thus it gives a chance to explore more edge cases. This also increases the chance to find new bugs.

Disadvantages:- Its disadvantage is that its not sure that all scenarios are covered and its difficult for an inexperienced tester to work with these test cases. Read more about Difference between High Level and Low Level Testing & their advantages at Findnerd.

How Offering Sales Can Benefit Your Internet Business.

There's an incredible technique online that can give you a sudden surge of requests immediately. Do you know what this method is? Well… I'm discussing the force of offering sales in your business. People love a decent deal – particularly in the event that they're love with the quality of your items/products.

I can recall when I was younger that significant retail stores would have some non-offering items out for sale outside of their store. These things costs were essentially reduced for the attempts of inspiring somebody to examine them and purchase. Also, trust it or not, this was a decent and fruitful technique/strategy.

I trust you can do likewise as well. It's very easy to take a considerable measure of non-selling things/items and pack them together to create 1 "super" product – all reduced to remove stock, and to profit from moderate offering things.
