Rails 3.2 write_attribute fix

[nickveys]

Updating to Rails 3.2 causes failure when injecting the tenant association on new objects. The attribute isn't there yet, and fails. The only attributes that are available at the time are the database columns themselves, so instead of using object.account, I used object.account_id and all is well.

Possibly related: rails/rails#4583

Guessing it's this commit: rails/rails@50d395f

Full stack trace of the failure:

Thx for fixing this Nick! Not on 3.2 myself yet, so hadn't seen it.
