problem validating input element of type radio

[resistorsoftware]

Problem seems to from my setup as follows: Post belongs_to :category. I use HAML for templates.

class Post < ActiveRecord::Base belongs_to :category validates_presence_of :category

So now, in Formtastic I am displaying some radio buttons for category via the Formtastic setup:

• semantic_form_for (@post, :html => {:class => 'validate'}) do |form|
  • form.inputs do = form.input :category, :as => :radio

which generates the radio buttons. Pressing submit however does not validate that a radio was selected, and by default none is selected.

The generated HTML is:

<legend><span class="label">Category<abbr title="required">*</abbr></span>    </legend><ol><li><label for="post_category_id_1"><input id="post_category_id_1" name="post[category_id]" value="1" type="radio"> Cat 1</label></li><li><label for="post_category_id_2"><input id="post_category_id_2" name="post[category_id]" value="2" type="radio"> Cat 2</label></li><li><label for="post_category_id_3"><input id="post_category_id_3" name="post[category_id]" value="3" type="radio">Cat 3</label></li></ol>

So I am stuck here. I see no class of "presence" added to my radio's. That seems to be the problem, but I am not sure why.

If I change to validation_presence_of :category_id

to ensure a category radio button is picked, a Javascript error is thrown about an illegal character... but the radios are rendered with the "presence" class.

How to get radio's generated like this to validate?

WIll review this when I get time, feel free to help me out by creating a app/spec that re-produce this behaviour.

Hi,

For sure there is a problem... using the belongs_to association causes an error in the way the javascript tries to hook in to the validation. I am sure it is simply off by an _id or something.

I will look into helping you for sure...

i'm seeing a similar problem here... maybe it's a result of formtastic wrapping labels around the radio input elements (instead of putting them after like validatious examples show) - just a guess
