I think you are running into problems because you are not following strictly the MVC pattern. I assume the code pasted is executed by the controller, correct? Maybe you should look at the as_json method to define json format from the model itself. For example, if Item is a model (inherited from ActiveRecord) and User is too, you should be fine defining two as_json methods inside the two models. That should allow you to render the data in the controller with a simple: render :json => @list If you need more "customization", you should consider redendering json via an erb view (leave the controller alone!!! :D). >> >> Thanks > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
