I'm not sure which model is causing the problem. I am now trapping
exceptions and the error first occurs when I execute root.save (see
***1***). 'root' is an instance of my Property model. I also get the
same error when executing code *** 2 *** (which follows the execution
of *** 1 ***) - member.save forces another (different) instance of
Property to be saved to the properties table which again triggers the
same error. FYI 'member.create_default_characteristics(user)' (in ***
2 ***) calls create_root() (*** 1 ***). The log file also suggests
that both errors are raised on an INSERT into my properties table.
*** 1 ***
def create_root(administrator)
begin
root = create_root_collection(self.pingee_name,
administrator,
GlobalAccessibility.new,
OwnerAccessibility.new)
root.save
rescue Exception => exe
logger.info("*** Member.create_root #{exe} #{root.name.to_s}
***")
end
self.root = root
end
*** 2 ***
def self.add_member_for_user(user)
member = new(:user_id => user.id, :pingee_name =>
user.pingee_name)
# Create the member's default characteristics and save it all
to the database in a single
# transaction
begin
transaction do
member.create_default_characteristics(user)
member.save!
end
member
rescue Exception => exe
logger.info("*** Member.add_member_for_user #{exe} ***")
end
end
