Following are the changes made in this commit:
- Added support for magic param `_method` just like Rails, Sinatra
etc.. Browsers which don't support `PUT`, `PATCH` and `DELETE` methods
can simulate them by sending `method` param in request body.
- The default Content-Type to parse request body submitted via forms
etc. is `application/x-www-form-urlencoded`. But if we send Ajax
request in Chrome ($.post) then by-default Content-Type is set to
`application/x-www-form-urlencoded; charset utf-8` which was not
getting matched. I changed the code from `==` to match against a
regular expression using `=~`.
- Print name and color of overridden HTTP method via Logger instead of
printing name and color or request's incoming HTTP method.
Making necessary changes as pointed by @sdogruyol
- Changed method name from`is_override_method_valid?` to
`override_method_valid?`.
- Refactored `if` condition in `override_method_valid?`.
