Correct use of :disabled option for text_field in Rails 2.3?

Question

I've just updated to Rails 2.3.2 from Rails 2.1 and noticed an issue with regards to using the :disabled option on input fields.

Previously we were using this option as a boolean, so we would indicate whether or not we wanted to disable the fields based on a method on the object, e.g.

f.text_field :amount, :disabled => @my_object.is_disabled?, :class => 'my_class'

This works fine in Rails 2.1 -- if is_disabled? returns true, the form field is disabled, otherwise it's not.

In Rails 2.3 however, this isn't the case. The form field is disabled regardless of the value of :disabled.

Does this mean I'll have to put an if statement around my f.text_field declaration such as:

<% if @my_object.is_disabled? %>
  <%= f.text_field :amount, :disabled => 'disabled', :class => 'my_class' %>
<% else %>
  <%= f.text_field :amount, :class => 'my_class' %>
<% end %>

Surely I'm missing something here?

Answer 1

They got rid of is_boolean_field? in rails 2.3. It is just boolean_field? now.

so:

f.text_field :amount, :disabled => @my_object.disabled?, :class => 'my_class'

should work fine.

Answer 2

Please ignore this thread. The issue I was having was actually with Javascript.

Adding :disabled => false adds "disabled=''" to the form field which correctly doesn't disable the form field after all.
