  # Two approaches - 1st: You can use the array notation [] on an activerecord to use it like a hash
  hash.each do {|key, value| new_ob[key] = value }

  # Or you can send to the method using period:
  hash.each do {|key, value| new_ob.send("#{key.to_s}=", value) }

It's hard to answer these in a tweet :)

You can't pass arguments to computed properties unless you are creating custom setters, but that's a whole different topic!

What you probably want to do here is use an itemController for each row you are displaying (with the button.)

{{#each thing in things itemController="thing"}}
  <button {{bindAttr disabled=thing.disabled}}>button</button>
{{/each}}
