How to lock the destroy action?

Rails
1

hi all.
Bus and Tickets/has_one, belongs_to/
Users and Tickets/has_many, belongs_to/
i want to realize next action:

“ticket.destroy.lock” if bus.tickets > bus.places*0.9
#if bus full for 90 %, users cant destroy their tickets (or bus never go
to
race:))

How correct to realize this locking action?

Validate the destroy action in the ticket model . More info Here

You could also use rails callbacks before_destroy

before_destroy :check_bus_status

private
def check_bus_status
return false if bus.tickets > bus.places*0.9
end

Bus has_one ticket? I don’t think you will make much profit!
