Deactivate instances on delete

[Lundie]

Hi,

I have created an application in which a customer model has many
locations. Customers are then assigned to an order, and one of their
locations is also assigned to the order.

My issue comes if a locations is removed from the customer, that was
assigned to an order. I have added an active field to the locations
table, and when I "delete" the location, it sets it to false.

My question is how to do the find statements correctly. Should I be
overwriting the find method within the locations model to only return
active locations? Then if I do that, and the order.location method is
called, how do I get it to return the old location that is not active.

Am I going about this the right way or is there a more efficient way
to handle it?

I have an old acts_as_paranoid plugin that does this. It overrides
#destroy and tries to override #find so that the use of the deleted_at
field is transparent. Problem is, it tends to break down in certain
edge cases. I recommend you keep it a little more explicit and use
the scope_out plugin.

Thanks!

scope-out looks like it will do the trick.
