Get remote server’s attributes and set them into local attributes via API.

User’s infomation will be used by other servers. So, prepare remote(provider) server for common user infomation provider, and Other servers(client) use ‘remote_attr_accessor’ to get common infomation of users.

Make file in “lib/remote_attr_accessor/config.rb” to Overwrite for your environment.

module RemoteAttrAccessor
  class Config
    def self.id_name
      'id'
    end

    def self.prefix
      'remote_'
    end

    def self.remote_json_key
      'users'
    end

    def self.remote_attrs
      [:email, :last_name, :first_name]
    end

    def self.remote_attrs_with_prefix
      @remote_attrs_with_prefix = remote_attrs.map{|attr| "#{prefix}#{attr}"}
    end
  end
end

Make file in “lib/remote_attr_accessor/api.rb” to Overwrite for your environments.

module RemoteAttrAccessor

class Api
  def self.get_remote_attrs(ids)
    # Write here API access code
  end

  def self.upsert_remote_attr(params)
    # Write here API access code
  end
end

end

    }
  }
}

Use sample for “User model”.

users = User.limit(1)
user.first.remote_email  # Get users email from remote server
user.first.remote_email = '[email protected]' # Set users email to remote server

users = User.limit(1)
RemoteAttrAccessor::Bulk.load_remote_attr(users) # Get users info in bulk and set instance variable
user.first.remote_email # Not access to remote server
