Hello,
I have a message model which belongs to a user. Users can be deleted,
but messages cannot. What can I do to reference a user that created a
message when it no longer exists?:
- Create a dummy user. When a user is deleted, assign the dummy user
id to all of its messages.
- Have a condition to check if the user exists, if not, don’t show
the user info.
- Don’t really delete the user, just flag it or change its state to
inactive.
These 3 occured to me. Any other options I should have in
consideration? Which one should I follow?
Thanks
Hi Elias O.
So do you want all messages be deleted when its user deleted?If so
in user model you can add like (Assuming your association is user
has_many messages)
user.rb
has_many :messages,:dependent => :destroy
Now when you delete a user all the dependent messages will also get
deleted

I would use 3. 1 is not worth serious consideration (dummy records are
seldom good things), and while 2 would work, it wouldn’t let you
differentiate between messages from different inactive users.
Thanks
