Thanks for adding these! I'm seeing a lot of style changes here and wanted to check -- could you take a moment to use Thoughtbot's Hound to do a quick style guide of this pull request and make sure it fits the standard Ruby guidelines?

We appreciate it, @PraveenVignesh!

Place the . on the previous line, together with the method call receiver.
Prefer double-quoted strings unless you need single quotes to avoid extra backslashes for escaping.

Thanks @courte

Is everything fine now?

@PraveenVignesh - You're definitely closer! 👏 Check out the HoundCI comments above to see some of the remaining style guide issues.

Also, the testing area of the codebase has changed quite a bit since you first submitted. For example, factory-girl has already been added, along with a number of new specs. You may want to take a few steps to get your version up to date.

1. From your own master branch, git pullYOUR_REMOTE_NAME_HEREmaster the HQ version of master
2. git checkout your add-specs-and-factory-girl branch
3. From there, run git rebase master and deal with any conflicts.
4. Run git push -f origin add-specs-and-factory-girl to update your pull request.

That process will cut down on any work you might do fixing code that's not be relevant anymore. Let me know if you have any questions!
