API Before Save script:

$message = "An event on the same time slot already exists.";

if (entity\isNew() && assignedUserId) {
    $existingId = record\findOne(
        'Event',
        null,
        null,
        'assignedUserId=', assignedUserId,
        'dateEnd>', dateEnd,
        'dateStart<', dateEnd
    );
    
    
    if ($existingId) {
        recordService\throwConflict($message);  
    }
    
    $existingId = record\findOne(
        'Event',
        null,
        null,
        'assignedUserId=', assignedUserId,
        'dateEnd>', dateStart,
        'dateStart<', dateStart
    );
    
    
    if ($existingId) {
        recordService\throwConflict($message);  
    }
    
    $existingId = record\findOne(
        'Event',
        null,
        null,
        'assignedUserId=', assignedUserId,
        'dateEnd<=', dateEnd,
        'dateStart>=', dateStart
    );
    
    
    if ($existingId) {
        recordService\throwConflict($message);  
    }
}

Where 'Event' should be your entity type.

You can also utilize API before save script.

There is no such a class, you just need to add your own logic. there are many ways to achieve this depend on your business logic.

Has anyone managed to write such a class? I'm looking for a solution too.

Hello,
I create new event entity ' Rooms Reservation'. Do you have any way to make it impossible to book one room at the same time?
Possibly any warning that there is a reservation in a certain period of time?
