Ruby on Rails

You could also use rails callbacks before_destroy 

http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html

before_destroy :check_bus_status

private

def check_bus_status

  return false if bus.tickets > bus.places*0.9

end

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?
