How change routes.rb?

http://localhost:3002/contr/index?action=‘UPDATE’

When I try to get params[:action] it return 'index' I can not use any other name, because it is command interface for other service Probably, I have to change routes.rb for the controller contr? But how?

What do you mean by "other service"?

I think it is not important But, if you will It is Oracle project. It send request to the rails project. It is not my project and I can not change list of parameters for request.
