subdomainitis | transparently use subdomains as parameters | Application Framework library

To install, add gem "subdomainitis" to your Gemfile. Then modify your routes.rb file; see the example below for usage. In the example above, the routes for spams will work regardless of the presence of a subdomain. However, the foos routes will only work if accessed WITHOUT using a subdomain; only http://mycompany.com/foos will work. Accessing bars routes will only work when a subdomain is provided. Additionally, the specific subdomain is passed into the controller as a path parameter, as specified by the first argument to subdomain_as. For example, http://subdomain.mycompany.com/bars resolves to {:controller => 'bars', :action => 'index', :account => 'subdomain'}. URL generation should work transparently as well; make sure you're using url instead of path generation (ie, foos_url instead of foos_path). Subdomainitis tries to fail fast by raising exceptions when a functional URL cannot be generated. Call use_fake_subdomains! to use the _subdomain GET parameter instead of an actual subdomain. This is useful for development where wildcard subdomains aren't possible, or for testing environments like Cucumber that don't support subdomains. Enabling this mode should be completely transparent if you're using URL generators. No changes to controllers are necessary.
