OK, i have a simple collection_select problem and I'm a newbie to ruby... I have a form that the user will select a bunch of stuff on to search through a database. I can't figure out how to get the return value out of a collection_select. Here is the code that displays a drop-down list of all ip addresses from a table - this works fine. I make my selection (along with others on the form) and want the result from this collection_select assigned to the value ipaddr. @ipAddress.find_all collection_select ("IpAddress", "ip", @ipaddress, :id, "ip") ** this works fine, everthing displays In my controller, I do: @ipaddr = params[:ip] This is obviously wrong as I get an error saying "Select * from ip_addresses where (ip_addresses.ip is NULL) ???? If I use a text input box with the following code, everything works fine, so I'm pretty sure the controller code is ok - just don't know how to get the result code from collection_select. <input type="text" name="ipaddr"> ** this works, but I don't want the user to have to type the IP address in - I want them all displayed to choose from. Thanks.
