Model spec for boolean

model.js

it("can understand checkboxes as booleans", function(){
  var form = $('<form />');
  form.append('<input name="available" value="1" checked="checked" />');
  var asset = Asset.fromForm(form);
  expect(asset.available).toEqual(true);

  form.find('input').prop('checked', false);
  expect(Asset.fromForm(form).available).toEqual(false);
});

// Or otherwise you'd have to do inn each (coffee) model something like:
// fromForm: (f) ->
//   super
//   @available = @available == '1' # and for each boolean
