ruby - Give argument to action on Rails -

how give argument action of controller.

i have action named action , controller named controller. want give argument action when go to

how know, argument passed in action?

the documentation best place start. right top, there's example of passing in parameter (in case, id):

get '/patients/:id', to: 'patients#show'

(the line above go in routes.rb file). id param available in controller, in params[:id]

so in case, you'd have line in routes.rb like:

get '/controller/action/:argument', to: 'controller#action'

and refer argument in controller params[:argument]
