> You can use collection\_select for this:

collection\_select(‘object’, ‘method’, @panels, :id, :name, {},  
{:multiple =\> ‘multiple’})

Also, it is sometimes considered quite rude to post messages with  
‘urgent’ in them (as you have done in your last 3 posts). The  
response from this group is normally very quick as everyone is happy  
to help, regardless of urgency on your part.

hi,

i got the answer when i user the panel table. but when i have to use  
Demogaphic\_categories table. if i use this it shows the error in

Expected ./app/models/demographic\_category.rb to define  
Demographic\_category

```
Like this.

```

dataBase name is - Demographic\_categories

fields - id, name, allow\_multiple

my coding:

index.rhtml

\<%= collection\_select(‘object’, ‘method’, @demographic\_categories, :id,  
:name, {},  
{:multiple =\> ‘multiple’}) %\>

in controller:

@demographic\_categories=Demographic\_category.find(:all);

```
can u tell this what's the error in this? please

```
