FormOption Helper

Hi,

I'm trying to generate a select with this :

select("music", "music_location_id", MusicLocation.find(:all, :order => "name ASC").collect {|p| [ p.name, p.id ] }, { :include_blank => true })

I need to add a description because the name is very "cryptic" and I'd like to do something like :

<option value="p.id">p.name (p.description)</option>

I don't know how I can do it with HTML option field. The api is not telling much about it.

Thanks

Rails just sticks the first part of each of those arrays in the option description. If p.name isn't what you want, then just put something else there.

The thing is that sometime, description is empty so I can't just put p.description but I would like p.name (p.description)

I don't think you understood me - you can put any bit of ruby you want there, as long as it evaluates to a string (or something that looks like it). For example "#{p.name} - #{p.description}"
