Date range overlap per user rails

Question

How can I make the validation of the date per user using the code below? When I logged in as a different user I am not able to create a reservation with the same dates. I ha

Answer 1

Guess you could try to add this to your validate:

validate :no_reservation_overlap, :uniqueness => { :scope => :user_id }

Not sure if this works for you cause, but you should give it a try. Good luck!

EDIT:

I would suggest a different approach:

validate :no_reservation_overlap


def no_reservation_overlap
  if (Reservation.where("(? BETWEEN date_start AND date_end OR ? BETWEEN date_start AND date_end) AND user_id = ?", self.date_start, self.date_end, self.user_id).any?)
     errors.add(:date_end, 'it overlaps another reservation')
  end
end

Guess this should work, please give it a try
