Ruby on Rails Advanced JSON Serialization

Question

I\'m looking to render an index of all articles along with a full article via JSON in my rails app, but I\'m having a little trouble figuring out how to do it.

Answer 1

Just to be clear the code above works with the :include and :except. And by works I mean it doesn't throw an error. The problem is it includes comments for every article in the index. I'm only looking to include comments for the :item and not any of the articles listed in the index.

I couldn't get nesting to work as a hash or an OpenStruct object.

Nesting on :include throws an error, nesting on :except doesn't throw an error, but nothing is filtered out, :created_at, etc. still show up.

...

@response = { :item => @article, :index => @index }

format.js { render :json => @response.to_json(
:except => {:item => [ :created_at, :updated_at, :draft, :id, :publish ]}, 
:include => { :item => {
        :comments => {
                :only => [:body]
        }
}}),
:callback => params[:callback]}
end
