Filter on laravel pivot table

Question

I have two tables in Laravel connected with a pivot table. The two tables are users and roles, and the pivot table is called role_user. The pivot table also contains two extra fields: start and stop. This way I can track which roles a user has had in the past.

Now I want to create a query that gets all users who currently have role_id = 3.

First I had used WherePivot, but apparently that is bugged.

I have now made the following query using Eloquent:

Role::with('User')
    ->where('id', '=', '3')
    ->where('role_user.start', '<', date('Y-m-d'))
    ->where('role_user.stop', '>', date('Y-m-d'))
    ->whereHas('users', function($q){
        $q->where('firstname', 'NOT LIKE', '%test%');
    })
    ->get();

But somehow I am getting an error that the column start of the pivot table cannot be found. But I can confirm in PHPMyAdmin that the column is there.

This is the entire error:

Illuminate \ Database \ QueryException
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'klj_role_user.start' in 'where clause' (SQL: select * from `klj_roles` where `id` = 3 and `klj_role_user`.`start` < 2014-06-02 and `klj_role_user`.`stop` > 2014-06-02 and (select count(*) from `klj_users` inner join `klj_role_user` on `klj_users`.`id` = `klj_role_user`.`user_id` where `klj_role_user`.`role_id` = `klj_roles`.`id` and `firstname` NOT LIKE %test%) >= 1)

Can someone tell me if I am doing something wrong or give me a hint where I should be looking now?

The error is telling you that you are missing the start column in your pivot table klj_role_user. What you should do is create the column. If the column is already there, ensure you are using the correct database.

I've also simplified your query a little bit. You don't really need a whereHas because you aren't trying to limit your roles by the users associated, but by the id, which in this case, you are using 3. A with() would work perfectly fine and wherePivot() seems to be working fine for me when used in conjunction with with().

$role = Role::with(array('users' => function($q)
{
    $q->wherePivot('start', '>', date('Y-m-d H:i:s'));
    $q->wherePivot('stop', '<', date('Y-m-d H:i:s'));
    $q->where('firstname', 'NOT LIKE', '%test%');
}))->find(3);


foreach($role->users as $user) {
    echo $user->firstname;
}
