Overriding object name

[rockwellll]

Expected behavior vs actual behavior

So, we want to have the key object to be present in the response of the serializer. However, since object is defined as attr_accessor :object.

It's hard to override, since we want to include the object key in the response. Is there any way to redefine the object as another serializer attribute, something like record?.

We can provide an option to override the key name, which then defaults to object?.

We can change the constructor to accept another argument, namely the object_name?.

This then can be done as follows

    def initialize(object, options = {})
       if options[:object_name]
          self.class.instance_eval do
              attr_accessor options[:object_name]
          end
       end
    end
