Ruby on Rails: comparison of values in html.erb

Question

I am using this example for uploading files in Ruby on Rails. I have some problems with the uploads/index.html.erb

I have some more variables like:
current_user.id - id of a user how is now online
user_id - user_id in a upload table, so it just like a foreign key, to assign several uploads to one user.

So, I want to list only those uploads, whose user_id corresponds to current_user.id. I try to do it in this line

((({%=file.user_id%}).to_i)==((<%=current_user.id%>).to_i))

Somehow it does not work, as uploads, whose user_id does not correspond to current_user.id, are listed as well.

<script id="template-download" type="text/x-tmpl">

  {% for (var i=0, file; file=o.files[i]; i++) { %}
  {% if ((({%=file.user_id%}).to_i)==((<%=current_user.id%>).to_i)){ %} 
    <tr class="template-download fade">    

      <td class="l">
       <a href="{%=file.url%}" download="{%=file.name%}">{%=file.user_id%}</a>
      </td>
      <td class="k">
       <a href="{%=file.url%}" download="{%=file.name%}"><%=current_user.id%></a>
      </td>  


      <td class="name">
       <a href="{%=file.url%}" download="{%=file.name%}">{%=file.name%}</a>
      </td>

       <td class="delete">
        <button class="btn btn-mini btn-danger" data-type="{%=file.delete_type%}" data-url="{%=file.delete_url%}"> 
          <i class="icon-trash icon-white"></i>

        </button>
        <input type="checkbox" name="delete" value="1">
      </td>



       <td></td>


    </tr>
{% } %}


    {% } %}
</script>

You can fetch uploads in controller smth. like

@files = Upload.where(:user_id => current_user.id) 

or if your User model has_many :uploads you can make

@files = current_user.uploads

then in @files variable in views you'll have only uploads corresponding to current_user
