Inside my model, I have the following:
friendly_id :id_and_title, use: [:slugged, :finders]
...
def id_and_title
"#{self.id}-#{self.title}"[0,100]
end
However, when creating a new record, the ID isn't being used on the slug field.
What I'm currently doing is:
after_save :regenerate_slug
...
def regenerate_slug
self.slug = nil
self.save
end
and I'm wondering if there is any other way of doing this?
So the problem is that friendly_id does not have access to "id" until after the record is created. The issue here is the after_save causes infinite recurrence, like Michal said, since it calls save.
You should use an after_create instead. You only need to do this once. In all subsequent updates to the record the id should be available for friendly_id to pick up.
