Hi Adam,
Please see my previous email. :-) Two great minds and all that.
By the way, where did you find the documentation for the pre-3 versions?
Thanks, Ken

Hi Ken,
I just checked the APIs, and since the new Rails 3.0 got release
last week or so, all the api sites have the latest docs. Rails 2.3.X
does not support the :restrict option, according to the docs. Rails
3.0 does, though. What version of Rails are you running?
Regards,
Adam

Hi All,
According to the Rails documentation, has_many associations have
a :dependent option that can be set to :restrict. "If set
to :restrict this object cannot be deleted if it has any associated
object". This is what I wanted so I have the following code in my
gallery model:
has_many :images, :dependent => :restrict
However, I am getting the following error:
"ArgumentError: The :dependent option expects
either :destroy, :delete_all, or :nullify (:restrict)"
Any idea what my problem is? I'm not sure why :restrict is shown in
parentheses in the error message. The documentation clearly shows
it as a valid option for :dependent...
Thanks, Ken
