Laravel: get models if count of relation has some condition - mysql

Question

I have User and UserComplains Models.
I like to retrieve users that have UserComplains more than 2 times in the last 24 hours.
users:
id
user_complains:
complained_id ->ref-> users.id
created_at
this is what I tried and it is working:
$users = User::select('users.*')->join('user_complains' , 'users.id' , '=' , 'user_complains.complained_id')
->whereRaw("(
select count(*) from `user_complains`
where `user_complains`.`complained_id` = `users`.`id`
and `user_complains`.`created_at` > ?) >= ?" , [now()->subHours(24), 2])
->groupBy("users.id")
->get();
the above code is fine and is working, but I wonder is there a better way to do that?!

Answer 1

For something like this you can use whereHas(). :
$users = User::whereHas('*relationship*', function ($query) {
$query->where('created_at', '>=', now()->subDay(1));
}, '>', 2)->get();
As mentioned in the documentation, you can pass additional checks as the 3rd and 4th param so in this case you want to say where the user has more that 2 user_complains.
NB You will need to replace *relationship* with the actual name of the relationship.

Answer 2

You can do the following:
User::whereHas('complaints', function($query) {
$query->where('created_at', '>=', '2020-04-26');
}, '>', 2)->get();
In order for this to work though you need to have set up a relationship between your User and UserComplaint models.
class User extends Model
{
public function complaints()
{
return $this->hasMany(UserComplaint:class);
}
}
