Active_model_serializers: Integer attribute was converted to string

[polarlights]

Expected behavior vs actual behavior

I'm new to AMS. I created a table named 'tags'. Here it is.

create_table "tags", force: :cascade do |t|
    t.string   "name"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
end

The data type of id is Integer. However the output is String.

Expected:

"data": [
  {
    "id": 1,
    "type": "tags",
    "attributes": {
    "name": "autem"
     }
  }
]

Actual:

"data": [
  {
    "id": "1",
    "type": "tags",
    "attributes": {
    "name": "autem"
    }
  }
]

Steps to reproduce

• Model

class Tag < ApplicationRecord
end

• Controller

module Api
  module V1
    class TagsController < ApplicationController
      def index
        @tags = Tag.all
        render json: @tags
      end
    end
  end
end

• Serializer

class TagSerializer < ActiveModel::Serializer
  attributes :id, :name
end

Environment

ActiveModelSerializers Version _0.10.0_:

Hi @polarlights - looks like you're outputting jsonapi. According to the jsonapi spec, id must be a string: http://jsonapi.org/format/#document-resource-objects

Yep. My fault. @richmolj Thank you very much! 👍
