select_tag not passing param using form_for

Sorry for the noob question but I am trying to convert a text_field to a
select_tag and although I don't get an error, the "active" param does
not pass.

This code passes does not pass the "active" param in the select_tag:
<% form_for :project do |f| -%>
<label for= "name">Project Name</label>
<%= f.text_field :name %>
<label for= "active">Active</label>
<%= select_tag "active", options_for_select( ["Yes", "No"] )%>
<%= submit_tag 'Submit' %>
<%= form_tag %>
<% end -%>

This code passes DOES pass the "active" param in the text_field:
<% form_for :project do |f| -%>
<label for= "name">Project Name</label>
<%= f.text_field :name %>
<label for= "active">Active</label>
<%= f.text_field :active %>
<%= submit_tag 'Submit' %>
<%= form_tag %>
<% end -%>

Can anyone point out where I'm going wrong?
thanks
