ActiveModel::Serializer attributes not working as expected #1988
Description
I am experiencing the following problem:
class Api::V1::RecordSerializer < ActiveModel::Serializer
class << self
def all_except_record_id
attribs = Api::V1::Base.retrieve_attributes(:record)
attribs - ['record_id'] if attribs
end
end
attributes self.all_except_record_id
has_many :notes
end
The problem:
When an object gets serialized, all attribute values are null even though the object has non-null values.
The workaround I have for this right now is the following:
class RecordSerializer < ActiveModel::Serializer
...
self.all_except_record_id.each do |a|
define_method(a) { object.send(a) }
end
end
The record resource looks like the following:
class Api::V1::Base < ActiveModelSerializers::Model
self.retrieve_attributes ... ; end
end
class Api::V1::Record < Api::V1::Base
class << self
def attribs
attrs = retrieve_attributes(:record)
attrs + ['notes'] if attrs
end
end
attr_accessor(*self.attribs)
# attributes *self.attribs does not work (NoMethodError)!
end
In my application controller, I have the following:
class ApplicationController < ActionController::API
include ::ActionController::Serialization
...
end
My reports controller renders like this:
class Api::V1::RecordsController < ApplicationController
def index
...
render json: reports, status: :ok
end
end
What am I doing wrong here?
