How to make a relation in laravel with multiple pivot tables?
I got a tables:
- users (id, name, surname)
- weddings (id, ...)
- wedding_user (id, wedding_id, user_id, role_id)
- wedding_user_permission (wedding_user_id, permission_id)
And I want to make a relation between Wedding and WeddingUser model (Wedding has many WeddingUser, WeddingUser belongs to Wedding).
Actually, if I'll ignore laravel relations, model will be:
//Wedding Model
public function users()
$users = WeddingUser::where('wedding_id', $this->id)->get();
return $users;
But I need to do this with the laravel relations.
I tried this:
public function users()
return $this->belongsToMany(
'AppModelsWeddingUser',
'wedding_user',
'user_id'
);
But it throws an error:
SQLSTATE[42000]: Syntax error or access violation: 1066 Not unique table/alias: 'wedding_user' (SQL: select `wedding_user`.*, `wedding_user`.`user_id` as `pivot_user_id`, `wedding_user`.`wedding_user_id` as `pivot_wedding_user_id` from `wedding_user` inner join `wedding_user` on `wedding_user`.`id` = `wedding_user`.`wedding_user_id` where `wedding_user`.`user_id` in (1))
How to do it correctly?

What you're looking for is the HasManyThrough relationship.
