Thanks for your thoughts. It got me on the right path. I ended up
with a solution that had a small amount of frontend javascript code to
manage the ajax calls. I used remote_function to create functions out
of the ajax call and put them in an array so I could call them
whenever I wanted. It looked something like this.
on th page:
var calls_to_be_made = [];
in the view:
<% subtasks.each do |subtask| %>
<div id="<%= dom_id(subtask) %>">
... content here
</div>
calls_to_be_made[calls_to_be_made.length] = function(){ <%=
remote_function(:update => dom_id(subtask), etc...) };
<% end %>
With this method I was able to start as many subtasks as I wanted like
this:
calls_to_be_made[0]();
calls_to_be_made[1]();
and then when one call returned I could have it kick of the next one
until there are none left.
Thanks!
