Question

I was previously adding my current user id to my tracks via the track controller’s create method using:

@track.user_id = current_user.id

This worked fine, however, i’ve now nested tracks within my releases model and am trying to do the same via callbacks in my releases model using:

before_save :add_user_to_tracks
before_update :add_user_to_tracks

def add_user_to_tracks
  tracks.each { |t| t.user_id = self.current_user.id}
end

I get an undefined method `current_user’ error, however, I know this is very close to working as if I test it using “99” instead of self.current_user.id it adds 99 to the user_id for each track in the db.

Any ideas why I can’t access current_user.id

I think you should send user_id from your form using hidden field.

If you don’t have user_id in Release model. You can create it as virtual attribute.

class Release < ActiveRecord::Base
  attr_accessor :user_id

  before_save :add_user_to_tracks 
  before_update :add_user_to_tracks

  def add_user_to_tracks
    tracks.each { |t| t.user_id = user_id}
  end
end
