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.
