Question

I have two same routes resources :errors with different url’s in different folders inside the routes.rb.

Routes:
---------

namespace :enr do
  namespace :locations do #( url: enr/locations/:location_id/errors)
    resources: errors 
  end

  namespace :rds do
    resources :errors #(url: enr/rds/errors)
  end
end

controller:
------------

I have a controller for `enr/rds/errors` only. 

how to change these two url’s by IF condition. For example,

if location_id is nil
i need to show this #(url: enr/rds/errors)
else
I need to show (url: enr/locations/:location_id/errors)
end

So it will change depends upon the location_id. Where should i write this condition to change the url’s by the location_id. Any Example would be more appreciated. Thanks

<% if location_id.nil? %>
  <%= link_to 'nil location_id', enr_locations_errors %> 
<% else %>
  <%= link_to 'not nil location_id', enr_rds_errors %> 
<% end %>

enr_locations_errors and enr_lrds_errors are not the only paths available. You can use one of the seven default routes (index, new, create, show, edit, update, destroy) or add a custom one. Check rake routes and look here
