Overriding

To override an association, call has_many, has_one or belongs_to with a block:

class PostSerializer < ActiveModel::Serializer
  has_many :comments do
    object.comments.active
  end
end

Attributes

To override an attribute, call attribute with a block:

class PostSerializer < ActiveModel::Serializer
  attribute :body do
    object.body.downcase
  end
end
