Unless I'm horribly misunderstanding, why not do event.user.id ?
When you do belongs_to :event that creates an instance method called
event on the Reminder class, so you can just go ahead and call this.
The 'this_reminder' you wrote is basically self but if you don't
specify a target for your method calls the ruby assumes self ie
self.event.user.id
is the same as
event.user.id [1]

[1] Not quite the same. If you had a local variable called event then
when you wrote event.user.id ruby would assume that you were talking
about the local variable not the method whereas with self there is no
ambiguity
