Ember way of outputting one row per model attribute (hasMany)

The problem with this approach is, that the object/model sent to the route via {{#link-to "events.show" row}}Tickets{{/link-to}} is not the original one and therefore I get errors at the other route.

So how is this done correctly?

Any hint would be highly appreciated :wink:

edit: saving the object in row.event helps. But it still feels wrong.
