Question

我正在使用select_tag并且当我更新所选值时未存储

当我更新：name，：tag value get first option

edit.html.erb

    <%= form_for(@name) do |f| %>

  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>

  <div class="field">
    <%= f.label :lname%><br />
    <%= f.text_field :lname%>
  </div>

  <div class="field">
    <%= f.label :tag %><br />
    <%= f.select :tag, "<option>1</option><option>2</option><option>3</option><option>4</option>".html_safe %>
  </div>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

<%= f.collection_select(:tag, [1,2], :to_i, :to_s, :prompt => 'Categories') %>
