Can't add class on select form helper in Rails 4

Using Rails 4. Can't seem to add class to select. I think other attributes like required, autofocus are also not there:

<%= form.select "availability", options_for_select(1..200), required: 'true', autofocus: 'true', class: 'form-control' %>

Output is below:

<select id="event_availability" name="event[availability]">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  ...
</select>

Any idea? Thanks.

Solution

  • Try this

    <%= form.select "availability", options_for_select(1..200), {}, {required: 'true', autofocus: 'true', class: 'form-control'} %>

    Possible options for third argument are :prompt and :include_blank
