Passing id attribute to options hash does not set form element id

[adriano-di-giovanni]

Despite Backbone.Form is a Backbone.View, I can't get the form id attribute set if I pass the id attribute to the options hash.

var
  AddEditTraineeForm = Backbone.Form.extend({
    id: 'addEditTraineeForm'
  });

Thanks for backbone-forms, Adriano

I post my solution. I think it can be useful to someone else.

First, override Backbone.Form.template

Backbone.Form.template = _.template('\
  <form data-fieldsets <% if (id) { %>id="<%= id %>"<% } %>></form>\
');

Second, use templateData attribute in the options hash

var
  AddEditTraineeForm = Backbone.Form.extend({
    templateData: {
      id: 'addEditTraineeForm'
    }
  });
