Is there a way to set the default value of a radio button that is  
coded in html with the value from an object? I am trying to set up an  
edit view for this object and am using submit\_to\_remote, so I cannot  
use the rails radio button helper. These are my radio buttons:

I have an object: @object, is there any way to set the checked to the  
@object.block\_avail value?

I think I got it figured out, I ended up writing a small javascript  
function that finds the radio button by a unique id and sets its value  
accordingly:

$(RadioId).checked = true;
