Re: [Rubycocoa-talk] ActiveRecord Overrides

[Eloy D. <e....@su...>]

Hi Cory,

There's indeed no other way yet to do it then you have done with  
rbSetValue_forKey.
There is only on_get for when data is being requested.

I'm interested to see the code on how you did it, so we could maybe  
turn it into a nicer solution.

About creating records from your code, you can simply use the normal  
way of doing this with AR.
So: Mailbox.create etc.

But if you're gonna add it to a ActiveRecordSetController, or anything  
other related to bindings,
you'll need a proxy. You can use #to_activerecord_proxy on the AR  
instance, or create it in one go with:
MailboxProxy.create etc.

You can than add it to the ActiveRecordSetController with  
#addObject(proxy).

Cheers,
Eloy
