创建一个自定义方法并在rails 4的ruby中的route.rb中调用它

Question

I am trying to do a redirect from url to another in rails 4. before doing the redirect I want to process one of the parameters and change its value in certain conditions(or not change it), then do a redirect. That's what I have tried so far

#routes.rb
get 'Client/:f_name/:l_name', to: redirect { |params, req|
        "clients_area/#{params[:f_name].parameterize}/#{my_process_params_method(params[:fname], params[:lname]) }"
      }

But I keep getting the error

undefined method `my_process_params_method' for ActionDispatch::Routing::Mapper:0x007fe1db4e4e08>

What am I doing wrong here? or is there a better solution?

The thing is that I must do this redirect at the level of the route and not create an action to take care of that.

I have realized the mistake. the method in the module should have been declared as a class method ( self.method_name ) and that the method should be called this was MyModul.my_process_params_method(var1, var2)
