Question

I have two models: Post and Tag. The Post model has an attr_accessor called :tag_name and the Tag model has an attribute called :name.

I have this form:

<%= form_for(@post) do |f| %>
  <%= render 'shared/error_messages' %>
  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.cktext_area :content %>
  </div>
  <div class="field">
    <%= f.label :tag_name %>
    <%= f.autocomplete_field :tag_name, autocomplete_tag_name_posts_path, :"data-delimiter" => ' ' %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

This is the output of the field:

<input data-autocomplete="/posts/autocomplete_tag_name" data-delimiter=" " id="post_tag_name" name="post[tag_name]" size="30" type="text">

I want the user to see the name of the tags as soon as they enter the show view.

Any suggestions of how to accomplish this?

EDIT:

I tried putting this at the end of the form:

<script type="text/javascript">
  $('#post_tag_name').val($('#post_tag_name').val() + <%= render @post.tags %>);
</script>

But nothing happens

Answer 1

$('#post_tag_name').attr('value', '<%= render @post.tags %>');
