alize don't works when the relation is assigned in a callback

[rjurado01]

I have two classes:

class ClassA
  include Mongoid::Document
  include Mongoid::Alize

  field :text
  has_many :class_b
end

class ClassB
  include Mongoid::Document
  include Mongoid::Alize

  belongs_to :class_a
  alize_from :class_a, :text

  before_create do
    self.class_a = ClassA.create(text: 'Hello')
  end
end

If I do this, alize don't work:

b = ClassB.create
 => #<ClassB _id: 5314662b7cf978428a000002, class_a_id: "5314662b7cf978428a000001", class_a_fields: {}> 
b.reload.class_a.text
 => "Hello" 
b.class_a_fields
 => {} 

When Alize is executed ?

Alize puts "from" callbacks in before_save. Per Rails callbacks before_save is fired before before_create. Furthermore, since alize_from is above the before_create block in ClassB, it would add its callback too early even if it was before_save. Here are some options to work around this.

Option 1 - manually call denormalize_from_all

 before_create do
    self.class_a = ClassA.create(text: 'Hello')
    self.denormalize_from_all
  end

Option 2 - Use before_save, and put alize_from after the before_save callback

class ClassB
  include Mongoid::Document
  include Mongoid::Alize

  belongs_to :class_a

  before_save do
    self.class_a = ClassA.create(text: 'Hello')
  end

  alize_from :class_a, :text
end
