I've set up a Rails form roughly following the instructions in this Railscast.
Here's the code for the form:
<% form_tag complete_todos_path, :method => :put do %>
<ul>
<div id="incomplete_todos">
<% @incomplete_todos.each do |todo| %>
<%= render :partial => todo %>
<% end %>
</div>
</ul>
<%= submit_tag "Mark as completed" %>
<% end %>
And here's the code for the todo partial:
<div class="todo">
<li>
<%= check_box_tag "todo_ids[]", todo.id %>
<%=h todo.name %>
<%= link_to 'edit', edit_todo_path(todo) %>
<%= link_to 'delete', todo, :confirm => 'Are you sure?', :method => :delete %>
</li>
</div>
It's working great, but I'm looking to start implementing AJAX and I need each checkbox to have a unique id. Right now, the input tags generated look something like this:
<input id="todo_ids_" name="todo_ids[]" type="checkbox" value="7" />
Every check box has the same id ("todo_ids_"), which is a problem. I suspect the solution is embarrassingly simple, but I'm not seeing it. Any tips?
