adding followers to a record via formula language

[jamie]

I’m trying to add followers via Formula in EspoCRM, but I think the example I was given might not be correct.

ChatGPT suggested the following:

Add a single follower
entity\addFollower('USER_ID');

Add multiple followers
entity\addFollowers(list('USER_ID_1', 'USER_ID_2'));

Example (current user)
entity\addFollower(entity\fetch('User', 'currentUserId'));

Common real-world pattern (add assigned user as follower)
entity\addFollower(assignedUserId);

However, I can’t find any documentation or evidence that these Formula functions actually exist in EspoCRM.

From what I can tell, this may not be valid Formula syntax and could be a mix of pseudo-code or backend logic rather than something available in Formula itself.

What I’m trying to achieve


I need to automatically add followers when certain conditions are met (e.g. sales need to follow a new account).

Any guidance would be appreciated.

There is no such formula function. You can write something like that to achieve the goal

$entityType = 'EntityType';
$entityId = 'ENTITY_ID';
$usersIds = list('USER_ID_1', 'USER_ID_2', 'USER_ID_3');
$size = array\length($usersIds);
$i = 0;

while ($i < $size) {
    $userId = array\at($usersIds, $i);
    
    $exists = record\exists('StreamSubscription', 'entityType=', $entityType, 'entityId=', $entityId, 'userId=', $userId);
    
    if (!$exists) {
        record\create('StreamSubscription', 'entityType', $entityType, 'entityId', $entityId, 'userId', $userId);
    }
    
    $i = $i + 1;
}

That is quite a workaround, but very usable, thanks
