Set Default Radio Button Value (html)

Rails
1

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;
