Sorry about that. When I get bored with it I’ll take it down.

Nice writeup! I never thought of providing JSON callbacks before I read your entry. I did notice Rails now provides a :callback option when you do a render :json (for anyone coming to this old post), e.g.: render :json => {:name => "David"}.to_json, :callback => 'show'

@Tim – that sounds great!

@Nic: ooooh yes, render :json => @something.to_json is definitely up on the sexy factor. I’ll be needing to add JSON-P to the project I’m currently on, so I might in fact do that and wrap it up as a plugin.

Thanks Nic!

@michael – the nice part about Tim’s current render_json function is that it auto-detect’s callback and variable parameters, instead of explicit options.

render :json => whatever, :callback => "myFunction" would be even nicer.

@Tim – ahh thanks for the link. That solution looks really thorough. It might be more Rails-Fu-ish if render_json became render(:json => json, options), but that could be me being anal.

All in all, wonderful!

I just created a render_json method in ApplicationController to perform the same thing.... no need for MinusR.

Nice!

I’ve never even thought about callbacks when consuming JSON. Nice example mate
