Instance Method Details

#url_for(options = {}) ⇒ Object

override default url_for method. Add ability to set default params.

Example:

'auctions_path' return '/auctions' by default
if you set @hash_of_additional_params = {:test => 1, my_param => 2} 'auctions_path' will return '/auctions?test=1&my_param=2'

You can use before_filer to do this stuff automatically. Example:

in HomeController:
 before_filter { @hash_of_additional_params = {:test => '1'} } #this will add test param to all urls in home views
