Rails form not passing radio button values to params hash

问题

I have used radio buttons in my app countless times, and never have experienced this issue, so I am assuming I am oblivious to a very dumb mistake. The form submits all the other model's attributes just fine, but for some reason, :referral_type just does not show up in params in the server output, and it of course is not saving to the db.

= form_for(@writer, :html => { :class => "user_new", :id => "user_new" }) do |f|
  - unless @writer.approved?
    .field.divider
      %label How did you hear about us?
      .writer-channel-input-container
        = f.radio_button :referral_type, "Searching Google"
        = f.label :referral_type, "Searching Google", value: "Searching Google"
      .writer-channel-input-container
        = f.radio_button :referral_type, "CraigsList"
        = f.label :referral_type, "CraigsList", value: "CraigsList"
      .writer-channel-input-container
        = f.radio_button :referral_type, "FlexJobs"
        = f.label :referral_type, "FlexJobs", value: "FlexJobs"
      .writer-channel-input-container.referral-detail
        = f.radio_button :referral_type, "A Forum"
        = f.label :referral_type, "A Forum", value: "A Forum"
      .writer-channel-input-container.referral-detail
        = f.radio_button :referral_type, "A Friend"
        = f.label :referral_type, "A Friend", value: "A Friend"
      .writer-channel-input-container.referral-detail
        = f.radio_button :referral_type, "Other"
        = f.label :referral_type, "Other", value: "Other"
      .referral-detail-input-container{ hidden: "hidden" }
        = f.text_field :referral_detail, disabled: "disabled", placeholder: "Please specify..."

It generates the following html, which appears to be exactly as intended:

<form accept-charset="UTF-8" action="/writers" class="user_new" id="user_new" method="post">
  <div style="margin:0;padding:0;display:inline">
  <input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="fWmxanHllFr0ufsxjEeZSKT6UQyRrLarIB/HOqWLxDA=" /></div>
  <div class='field divider'>
    <label>How did you hear about us?</label>
    <div class='writer-channel-input-container'>
      <input id="writer_referral_type_searching_google" name="writer[referral_type]" type="radio" value="Searching Google" />
      <label for="writer_referral_type_searching_google">Searching Google</label>
    </div>
    <div class='writer-channel-input-container'>
      <input id="writer_referral_type_craigslist" name="writer[referral_type]" type="radio" value="CraigsList" />
      <label for="writer_referral_type_craigslist">CraigsList</label>
    </div>
    <div class='writer-channel-input-container'>
      <input id="writer_referral_type_flexjobs" name="writer[referral_type]" type="radio" value="FlexJobs" />
      <label for="writer_referral_type_flexjobs">FlexJobs</label>
    </div>
    <div class='writer-channel-input-container referral-detail'>
      <input id="writer_referral_type_a_forum" name="writer[referral_type]" type="radio" value="A Forum" />
      <label for="writer_referral_type_a_forum">A Forum</label>
    </div>
    <div class='writer-channel-input-container referral-detail'>
      <input id="writer_referral_type_a_friend" name="writer[referral_type]" type="radio" value="A Friend" />
      <label for="writer_referral_type_a_friend">A Friend</label>
    </div>
    <div class='writer-channel-input-container referral-detail'>
      <input id="writer_referral_type_other" name="writer[referral_type]" type="radio" value="Other" />
      <label for="writer_referral_type_other">Other</label>
    </div>
    <div class='referral-detail-input-container' hidden='hidden'>
      <input disabled="disabled" id="writer_referral_detail" name="writer[referral_detail]" placeholder="Please specify..." size="30" type="text" />
    </div>

I look forward to one of you pointing out my overlook, thanks!

After 4 days of messing with this I found the issue. According to: https://code.google.com/p/chromium/issues/detail?id=244645, it is a bug with Chrome autofill removing the check of radio buttons and checkboxes in certain circumstances. Disabling autofill fixed the issue. It should be fixed in Chrome v28 (I am currently using Version 27.0.1453.116). Hope this saves someone some time.
