How can I "select" a model to add to my has_many relationship?

Here's the situation ...

Client has_many :licenses, :as => :holdable Vendor has_many :licenses, :as => :holdable

License belongs_to :holdable, :polymorphic => true License belongs_to :asset

So when creating/editing an asset, I also need to create/edit the licenses associated with that asset. I need an intuitive way to allow the user to select from a list of possible "holders" and assign one to a license. My idea was to have some sort of AJAX "suggest" type field where the user would type in the name of the holder and you get the right object back.

Anyways, I'm having a hard time coming up with an elegant way to populate the asset's holdable property using AJAX. Any ideas on how I could pass the info during a create/update?

TIA,

Sean

Wow! That is a great solution. I've seen that guys screencasts a few other times but they've fallen off my radar lately. Thanks for the great suggestion.
