[Ruby] JavaScript in FormHelpers

That works as well because you're assigning the hash to a local  
variable called "options", then the assignment returns the value set  
to it.

Effectively, it's the same as:

<% options = {:onclick => "javascript:redirect('QueryA1R1.rhtml'" } %>
<%= radio_button "post", "category", "rails", options %>

I've been working with ruby and rails every day for the past year and  
still find huge gaps in my knowledge.  The best thing I can recommend  
is to re-read the agile books every three months.  Sometimes as  
little as a single paragraph, skimmed on an earlier reading, can  
click and be incredibly useful from then on.

It was just last week that I discovered .is_blank? for Objects.   
That's one value packed little test, and I had no idea it existed.
