There are several concerns when using AR Enum with API, when you receive a payload it is hard to handle a proper error message.

ruby class Conversation < ActiveRecord::Base enum status: [ :draft, :active, :archived ] end

curl curl -X POST \ {{domain}}/api/v1/conversations \ -H 'Accept: application/json' \ -H 'Content-Type: application/json;charset=UTF-8' \ -d '{ "conversation": { "title": "Relativity theory", "status": "unactive" }'

ruby conversation = Conversation.new conversation.status = "unactive" => ArgumentError ('unactive' is not a valid status)

instead with EnumFor

ruby class Conversation < ActiveRecord::Base extend EnumFor enum_for status: { draft: 0, active: 1, archived: 2 } validates :status, inclusion: statuses.keys end

curl curl -X POST \ {{domain}}/api/v1/conversations \ -H 'Accept: application/json' \ -H 'Content-Type: application/json;charset=UTF-8' \ -d '{ "conversation": { "title": "Relativity theory", "status": "unactive" }'

ruby conversation = Conversation.new conversation.status = "unactive" conversation.valid? => false conversation.errors.messages => { status: [ 'is not included in the list' ] }

Installation

Add this line to your application’s Gemfile:

ruby gem 'enum_for'

And then execute:

$ bundle

Or install it yourself as:

$ gem install enum_for

Usage

You need to extend the AR class you want to use it:

ruby class Conversation < ActiveRecord::Base extend EnumFor enum_for status: { draft: 0, active: 1, archived: 2 } validates :status, inclusion: statuses.keys end
