Laravel query orderBy pivot table value

Question

I have a trouble that I can't resolve.

I have two models User & Orgs They are bounded by a pivot table user_org through a belongsToMany relationship. An user can be member of many Orgs and an Orgs can have many users.

Into my controller I craft a query : $users = User::query();

I wanted to get $users depending on various filters, no problem to apply filters, then order them by orgs if they have one "VIP" orgs through some weighting with orderByRaw("CASE WHEN org_id = X THEN 1 ELSE 2 END")

[EDIT] Full query over here :

$users = User::query();
$queryOrder = "CASE WHEN org_id = 13 THEN 1 "; 
$queryOrder .= "WHEN org_id = 14 THEN 2 "; 
$queryOrder .= "ELSE 3 END"; 

$users = $users->join('user_org', 'user_org.user_id', '=', 'users.id')->orderByRaw($queryOrder);

Adding distinct() didn't do the job.

Problem, the result of the query give me some duplicate as an user can belongs to severals orgs. I can't manage to sort the users giving me firstly the users who belongs to the VIP orgs.

Did you have any clue for me ?

Thanks a lot !

Answer 1

What about adding a distinct clause ?

$users = User::query(...)->distinct()->get();

Just FYI, this question reminds me a recent Laracon talk . He used 'orderBySub'. This could be an alternative for you.

Answer 2

Finally I've managed by problem differently. Because the distinct is not working due to the inner join, the order are lost in the better case.

So I've made a "score" computed column in order to group by user_id and max(score).

Here is the request :

            $users = $users->join(
                    DB::raw("(select id, score from (
                                select user_id as id, MAX(CASE WHEN org_id = 13 THEN 5 WHEN org_id = 14 THEN 4 ELSE 0 END) as score 
                                FROM `user_org`
                                group by user_id
                                order by score DESC
                                ) as x)
                            as d"), function($join){
                    $join->on("d.id","=","users.id");
            });

Thanks for the answer and the help ! Cheers
