Is the documentation for serializing POROs wrong?

[jholton]

The docs say to use the attributes method:
https://github.com/rails-api/active_model_serializers/blob/master/docs/howto/serialize_poro.md

# my_model.rb
class MyModel < ActiveModelSerializers::Model
  attributes :id, :name, :level
end

However, using version 0.10.3 in my project, when I try this I get an error:
undefined method 'attributes' for MyModel:Class (NoMethodError)

Using attr_accessor, as the previous documentation describes, works for me:
https://github.com/rails-api/active_model_serializers/blob/05618eac3d1b793cca8c2337090d00102f44f442/docs/howto/serialize_poro.md

# my_model.rb
class MyModel < ActiveModelSerializers::Model
  attr_accessor :id, :name, :level
end

Does the current documentation describe behavior not available in 0.10.3?
Or is the documentation wrong?

Thanks.

I ran into the same issue - the documentation on GitHub reflects the master branch, which contains the changes in this pull request that adds support for the attributes method, but haven't been pushed as a new gem version (0.10.4 I believe). To fix for now I just updated my Gemfile to use the git repo:

gem 'active_model_serializers', git: 'git://github.com/rails-api/active_model_serializers.git', branch: 'master', require: true

Ah, I see. Thanks.

@jholton @mzaccari Thanks for the issue and helping each other out! I have a little more work to do before the next release. Let me know how things are going. ;)
