In our application, many resources are nested under a common resource representing an organization. Most URLs include an organization ID the following pattern: /:organization_id/notifications/:id.
My problem is that I always have to give the current organization to generate the URL to any model. For example, the link to an existing notification would be link_to [@organization, @notification].
Since a notification already belongs to an organization, I was wondering if it was possible to generate my URL using link_to @notification and it would actually generate a URL including the organization ID of the notification. I was hoping that a configuration in the model would be able to achieve this but I could not find anything in the guides, the docs or the source code of Rails.
I would like to keep the organization ID visible in the URL as this is an information that is used by our customers. So I do not want to use shallow nested resources for this problem.
We are using Rails 5.2.0.
You want the resolve route definition method.
It is designed to do exactly what you want: configure a different behaviour when a single model instance is passed to url_for (as link_to does, for example).
Specifically, in your config/routes.rb, something like:
resolve("Notification") do |note|
[:notification_organization, note.organization, note]
end
It sounds like you were on the right track -- it's just a routing concern rather than a model one.
