Rails nested resources redirection after update - ruby-on-rails

Question

Good day all, I'm pulling my hair out on this one, I've seen similar posts but none of them get me in the direction I'm trying to go.
That said, I've got a pretty complex app that's relying heavily on nested resources and name-spacing, when I save a record it saves perfectly
and redirects correctly. When I update that same record the URL changes but not as I would expect. I understand the flow from edit to update and
the set_input call pulling the params[:id], what I don't understand is why the URL is changing the parents resource to reflect the record ID.
/servers/1/features/rsyslog_inputs/12/edit"
changes to the following after update
/servers/12/features/rsyslog_inputs/12/edit"

Answer 1

seeing your forms, controller and the requirement, i would advice that you use the route helpers and pass in the appropriate parameters there
like in your form explicitly set the form url to
server_features_rsyslog_input(server_id: params[:server_id], id: #input.id)
and in your controller too pass in the parameters explicitly

Answer 2

So this actually turned out to be a redirection issue in the update method. I wasn't specifying the server_id which wouldn't allow the redirection back to the index based on the server.
