hi,

im trying to integrate model\_auto\_completer. the dropdown is working  
nicely, my userdefined function:  
auto\_complete\_belongs\_to\_for\_X\_Y\_Z works as well, but then im stuck.  
via model\_auto\_completer\_result i can see the id, either attached to the  
model(eg account\_ID) or via my own partial:

 \<% for author in @authors %\> - \<%=h author.title %\>
 \<% end %\>

but what i wann do is: as soon the user selected one entry out of the  
dropdown, i need to populate the rest of the form with data related to  
the unique ID of that record. so\> how to i access the ID???

thx tom
