Hi,

I have this code:  
\<%= debug @deposit.to\_user\_id %\>  
\<%= select(“deposit”, “to\_user\_id”, User.find\_all.collect {|u|  
[u.fullname, u.id.to\_s] }, {:prompt =\> ‘Select a user’, :selected =\>  
@deposit.to\_user\_id} ) %\>

It generates this:

Why doesn’t it generate the prompt and the selected?

With kind regards,  
Leon B.

Anyone? If I change the to\_user\_id in user\_id it works. But that  
requires a change in the database and makes the whole just less  
readable. Especially because there’s another field called  
from\_user\_id.

Maybe there’s anoyher way of achieving the same?

Ahh… got it. This worked:  
\<%= collection\_select(“deposit”, “to\_user\_id”, User.find\_all, “id”,  
“fullname”, :selected =\> “to\_user\_id”) %\>

But now :prompt does not work anymore…  
\<%= collection\_select(“deposit”, “to\_user\_id”, User.find\_all, “id”,  
“fullname”, :selected =\> “to\_user\_id”, :prompt =\> “This is a test”)  
%\>

Ah…  
This works:  
\<%= collection\_select(“deposit”, “to\_user\_id”, User.find\_all, “id”,  
“fullname”, {:prompt =\> ‘Dit is een test’} ) %\>

if to\_user\_id would not be “0”. It’s an integer and probably it’s zero  
to default. Can I change this behaviour? Else the selectlist won’t  
work. And setting it to ‘’ before each selectlist seems like a crappy  
solution.

Ah got it… Yes again…  
table.column :to\_user\_id, :integer, :default =\> nil does it
