```

controller is pretty simple

```

  def create
    @work = current_user.works.build(permitted_params.work)
    if @work.save
      render json: @work, status: :created
    else
      render json: { status: 'error', message: @work.errors.full_messages }, status: :bad_request
    end
  end

```

raw request body

```

According Rails 4.1 release note:

Removed support for the encode_json hook used for encoding custom objects into JSON. This feature has been extracted into the activesupport-json_encoder gem. (Related Pull Request / More Details)

Because activesupport doesn't encoding invalid code anymore. Add activesupport-json_encoder gem to Gemfile fix this issue.
