Problems with Modal in Rails opening the same object - ruby-on-rails

Question

I'm maintaining an older Rails 3.2.22 app and I'm trying to add a modal to pop up with a simple form to add a note.
Here is my view (cut down for readability)
<% #assigned.each do |call| %>
<%= link_to "Notes", '#ajax-modal', data: { toggle: "modal", target: "#note-modal" }, class: 'btn btn-small btn-inverse' %>
<%= render 'layouts/note_modal', :call => call %>
<% end %>
Here is my modal app/views/layouts/_note_modal.html.erb
<div id="note-modal" class="modal hide fade" tabindex="-1">
<div class='modal-header'>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 class="modal-title"><%= call.incident_number %> Notes</h3>
</div>
<div class='modal-body'>
<div class="modal-body-content">
<%= form_for(#note, url: call_note_calls_path, html: {class: "form-inline"}) do |f| %>
<%= f.text_field :message, :maxlength => 255 %>
<%= f.hidden_field :call_id, value: call.id %>
<%= f.hidden_field :user_id, value: current_user.id %>
<%= f.button "Add Note", class: 'btn btn-info btn-small', data: {disable_with: "<i class='icon-spinner'></i>Posting..."} %>
<% end %></div>
<div class="ajax-loader">
</div>
</div>
<div class='modal-footer'>
<button type="button" data-dismiss="modal" class="btn">Close</button>
</div>
</div>
When I load the page and there are several calls I click on the notes link, the partial renders in a modal and I can submit a note. The problem is if I have 10 calls on the screen no matter which notes link I click on it adds a note to the first call on the screen.
Am I passing locals incorrectly? I know this code is inside of the block so it should pull the call object and pass it as a local to the partial in the modal but it's not.
Any help is greatly appreciated.

Answer 1

I think the issue is that you render the modal each time for a note but they all have the same id. So you are always opening the first modal. Actually IMHO you just need to render the modal once and pass the note_id via an data attribute on the link which triggers the modal. So basically configure the modal via the caller.

I was able to figure this out on my own and still render the partial within the loop by calling an index as part of the target ID for the modal. Working code below.
<% #assigned.each_with_index do |call, index| %>
<%= link_to "Notes", '#note-modal', data: {toggle: "modal", target: "#note-modal#{index}" }, class: 'btn btn-small btn-inverse' %>
<%= render 'layouts/note_modal', call: call, index: index %>
<% end %>
<div id="note-modal<%= index %>" class="modal hide fade" tabindex="-1">
<div class='modal-header'>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 class="modal-title"><%= call.incident_number %> Notes</h3>
</div>
<div class='modal-body'>
<div class="modal-body-content">
<%= form_for(#note, url: call_note_calls_path, html: {class: "form-inline"}) do |f| %>
<%= f.text_field :message, :maxlength => 255 %>
<%= f.hidden_field :call_id, value: call.id %>
<%= f.hidden_field :user_id, value: current_user.id %>
<%= f.button "Add Note", class: 'btn btn-info btn-small', data: {disable_with: "<i class='icon-spinner'></i>Posting..."} %>
<% end %></div>
<% call.notes.each do |n| %>
<li><%= n.message %> added by <%= n.user.username %></li>
<% end %>
<div class="ajax-loader">
</div>
</div>
<div class='modal-footer'>
<button type="button" data-dismiss="modal" class="btn">Close</button>
</div>
</div>
