Passing Back Collection Values From Associations

[Vladiim]

I've got a form for a booking with a user association

To display the collection of user names I'm using the following:
= f.association :client, :collection => current_user.teaching.collect
{ |c| c.username }

The issue: although this works it doesn't pass the selected user's id
back to the db (it's passing back the username) making the booking
invalid (note: the id passed back is defaulting to 0)

Which additional params ensure I'm sending back the selected user's id
rather than their username?

You have to map the collection to a pair of text and value attributes, ie an array containing the labe and the value for each option tag that will be generated. Try this:

  f.association :client, :collection => current_user.teaching.collect { |c| [c.username, c.id] }
