Details

Extend your RESTful controllers by simply returning the number of models in the database for any call to a URL like modelname/count.

Examples:
/users/count
returns User.count in plain text

/articles/1/comments/count.xml
returns Comment.count as XML, e.g.
<comments type="integer">5</comments>
Note: this does not return Articles.find(1).comments.count like it maybe should!

Usage

Simply require in environment.rb with:
config.middleware.use "ResourceCount"

Requirements when not using Rails:

1. Use Rails conventions (controller name is pluralized name of model)
2. Model.count should be available, but size or length also works
3. These String methods from Rails need to be available: singularize, classify and constantize
