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
