Rails spinoffs - Apr 2007 - Getting AutoComplete to populate other fields

Hi all,

I am looking for the simplest method to accomplish the following:-

I have a RoR form for taking line items for an order.  I have got
autocomplete working for the Product Description so that users can
find a product really easily.  What I want though, is for whenever a
user accepts a product description using the autocompleter, the
product_code, product_units and product_price fields also get
automatically populated from the selected record from the product
masterfile.

What is the best way to achieve this using RoR?

Thanks

Put these in your <li>''s as well, say in <span> elements
with proper
class names (you can then exclude them from auto-completion use by
properly setting the auto-completer''s ''select''
option).

Then use the afterUpdateElement callback to grab these ($$ or
getElementsByClassName should do) and auto-populate your other fields.

Christophe,

Thanks for this information - I got it working great now.

I had some trouble getting the :select option to pick out the <span>
that I was after, but I soon worked out that the syntax for the
autocomplete was:-

<% text_field_with_auto_complete :model, :column, {}, :select =>
"myspan" %>

I didnt realise that you needed the empty braces ''{}'' after
the column
name to get the parameters in the right order.

Thanks again for your help - I appreciate it.
