I present you my application:
My problem is the following: it is impossible to block a reservation, if the time slot is already reserved.
user 1 takes a reservation from 02/03/2015 to 05/03/2015
user 2 can also take a reservation from 02/03/2015 to 05/03/2015
I want it to be impossible to make a reservation for user 2
I want the reservation to be blocked for everyone, once the reservation is made.
I don’t want a double reservation.
