Hold up... Ruby doesn't have "view pages" by itself. Maybe you wanted:

http://groups.google.com/group/rubyonrails-talk

I'll try to answer anyway, but you haven't given a lot of information here.

I don't think that defines an array, and I'm not sure it belongs in view code 
anyway. But where is 'asset' actually defined?

That's really not looking like an array. It's looking like you're accessing a 
hash.

So now there's an even more important question: What is 'height_ser' and 
'width_ser', and where are those defined? Do you really need to convert them 
to json here?

What's asset_org? You never mentioned it before this.

Wherever you end up asking your question, you probably want to provide a LOT 
more detail. Paste the actual error, and if it's a stacktrace, you may want to 
paste at least a few more lines of it than you think you need, if not the 
entire trace.
