Laravel - 认证返回“where子句中的列'id'是不明确的”因为GlobalScope中的JOIN

Question

I'm having a trouble with the Laravel Authentication. When I make a login, Laravel returns the error: "Column 'id' in where clause is ambiguous" because I have a GlobalScope that has a JOIN.

The Error:

Column 'id' in where clause is ambiguous (SQL: select * from `users` inner join `playables` as `p` on `users`.`id` = `p`.`user_id` inner join `league_of_legends` as `lol` on `p`.`playable_id` = `lol`.`id` and `p`.`playable_type` like '%LeagueOfLegends%' where `id` = 1 and `users`.`deleted_at` is null and `users`.`banned` = 0 limit 1)

Login Code:

Auth::login($user);

Global Scope:

$builder->join('playables as p', 'users.id', '=', 'p.user_id')
        ->join('league_of_legends as lol', function ($join) use ($game){
            $join->on( 'p.playable_id', '=', 'lol.id');
            $join->on('p.playable_type', 'like', DB::raw( "'%$game%'"));
});

I tried to rename the primary key of model User but this cased others errors. There is an alternative? Or I have to use Local Scopes??

Thanks.

如果您像我一样使用Eloquent Builder，解决方案是在具有全局范围的模型上指定主键名称：

protected $primaryKey = "users.id";

Answer 2

Builder store it's where clauses publicly in array as $builder->wheres .

So you can access and modify the variable. But only for this time because it's not the correct way, obviously.

The current $builder->wheres is like this

array(3) {
  [0]=>
      array(5) {
        ["type"]=> string(5) "Basic"
        ["column"]=>  string(2) "id"
        ["operator"]=> string(1) "="
        ["value"]=>  string(1) "1"
        ["boolean"]=> string(3) "and"
  }
  // ... Others are array of column deleted_at and banned
}

So just loop the $builder->wheres and modify it as

foreach( $builder->wheres as $key => $item ){
    // Only modify column of 'id'
    if( $item['column'] == 'id' ){
        $builder->wheres[$key]['column'] = 'users.id';
        break;
    }
}

You can put second join clause as where clause

$builder->join( 'league_of_legends AS lol', function( $join ){
    $join->on( 'p.playable_id', '=', 'lol.id');
})->where( 'p.playable_type', 'LIKE', DB::raw( "'%$game%'") );

Finally do select for users

// This also reset the SQL SELECT that previously defined
$builder->select( 'users.* AS users' );

So it will be

foreach( $builder->wheres as $key => $item ){
    // Only modify column of 'id'
    if( $item['column'] == 'id' ){
        $builder->wheres[$key]['column'] = 'users.id';
        break;
    }
}

$builder
    ->select( 'users.* AS users' )
    ->join( 'playables AS p', 'users.id', '=', 'p.user_id' )
    ->join( 'league_of_legends AS lol', function( $join ){
        $join->on( 'p.playable_id', '=', 'lol.id');
    })->where( 'p.playable_type', 'LIKE', DB::raw( "'%$game%'") );
