I have a table with (among others) :prefix and :lastname

In my view in a collection\_select I want to see “prefix lastname”. I  
have ab-so-lu-te-ly no idea how to do this. Can anybody show me?

Add a method to your model that returns “#{prefix} #{lastname}”,  
and use this as your text method in collection\_select.

We develop, watch us RoR, in numbers too big to ignore.

I guess I’m still not used to the simplicity of rails…
