Rails - Nov 2005 - Validation + AJAX

Hi!

 

I have a simple task list application, the top of the page is a form to be
filled in and insert a new task. When a new task is added, the bottom part
of the page is updated via AJAX with all the tasks. 

 

My question is: how do I validate the task information when it is submitted
via Rails (not JavaScript) and show the errors on the top of the page, and
only if it is valid, should it then proceed to update the task list. ? What
has happened is that my div with the AJAX content gets updated with the same
form as the top of the page, but showing the errors .. ?

 

Thanks,

Alessandro

Hopefully, this reply is not too late to be useful.

I''ve just finished a small text on this subject. You can find this text
at
http://www.bigsmoke.us/ajax-validation-in-rails/

Note that I haven''t tested the page in IE. If you find anything
incomplete
or missing, please let me know.

Happy coding,

Rowan
