All,
I have a many_to_one relationship object between products and
categories and I want to return the category too using JSON results
but it seems that rails only gives back the products JSON object on
the view layer. This is the piece of code:
@products = Product.find(:all, :include => [:category] )
respond_to do |format|
format.json {render :json => [@products]
end
Have I missed something? I thought by doing this I have enabled the
eager fetching? Or does eager fetching does not work with JSON
results?
Thanks in advance.

Darn, I returned an array object besides that products instance, giving that to_json will give backslashes to the quotes.
