    #add_url_helper(name, defaults, &block)  
  



  

    

Given a name, defines name_path and name_url helpers. Used by ‘direct’, ‘resolve’, and ‘polymorphic’ route helpers.

    #define_url_helper(mod, name, helper, url_strategy)   (private)
  



  

    

Create a URL helper allowing ordered parameters to be associated with corresponding dynamic segments, so you can do:



foo_url(bar, baz, bang)



Instead of:



foo_url(bar: bar, baz: baz, bang: bang)



Also allow options hash, so you can do:



foo_url(bar, baz, bang, sort_by: 'baz')
