Hi, I’m having some problem with getting collection\_select to return  
the current value when editing a record. According to everything I’ve  
seen, there was an issue but it’s been fixed, but I can’t figure out  
why it isn’t returning the current value as a selected option. I’ve  
checked the table structures, and both the call\_driver.product\_line\_id  
and the product\_line.id are int(11).

What am I missing?

Here’s the code;

### 
 Product Line \<%= @drivers.product\_line.name %\> # Troubleshooting only \<%= collection\_select(:driver,"product\_line\_id",@productline,:id,:name) %\> ###

The controller;

### 

def driver\_edit  
@drivers = CallDriver.find(params[:id])  
@productline = ProductLine.find(:all)  
end

### 

And the debug results for CallDriver

— &id001 !ruby/object:CallDriver  
attributes:  
name: Billing (TV)  
segment\_id: “1”  
platform\_id: “1”

consolidation\_id: “1”  
skill\_id: “1”  
created\_at: 2008-01-10 20:04:04  
attributes\_cache: {}

Debug results for ProductLine;
