Instance Method Details

#R(c, *g) ⇒ Object

Overrides Camping’s routing helper to make it possible to route RESTful resources.

Some usage examples:

R(Kittens)            # /kittens
R(Kittens, 'new')     # /kittens/new
R(Kittens, 1, 'meow') # /kittens/1/meow
R(@kitten)            # /kittens/1
R(@kitten, 'meow')    # /kittens/1/meow
R(Kittens, 'list', :colour => 'black')  # /kittens/list?colour=black

The current output format is retained, so if the current @format is :XML, the URL will be /kittens/1.xml rather than /kittens/1.

Note that your controller names might not be loaded if you’re calling R inside a view module. In that case you should use the fully qualified name (i.e. Myapp::Controllers::Kittens) or include the Controllers module into your view module.
