錯誤：型號是要求列「ID」，但$鍵設置爲其他不同

Question

錯誤：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'where clause' (SQL: update `genre_books` set `provider_id` = ?, `genre_id` = ? where `id` is null) (Bindings: array (0 => 3, 1 => 466284,)) 

它的成功，但該表中添加一些數據，但它仍處於圍在中間得到這個錯誤更新。

型號：在控制器

class GenreBook extends Eloquent { 

    public $table = 'genre_books'; 
    public $timestamps = false; 
    public $publicKey = 'book_id'; 

    public function setRank($a) { 
     $this->sort_order = $a; 
    } 

    public function setProviderId($a) { 
     $this->provider_id = $a; 
    } 

    public function setBookId($a) { 
     $this->book_id = $a; 
    } 

    public function setGenreId($a) { 
     $this->genre_id = $a; 
    } 

} 

代碼：

GenreBook::unguard(); 
foreach($bookList as $genreId => $books) { 
    if(count($books) > 0) { 
    foreach ($books as $book) { 
     $genreBookRecord = GenreBook::where('book_id',$book['asin'])->where('provider_id',3)->first(); 


     $newGenreBook->setProviderId(3); 
     $newGenreBook->setBookId($book['asin']); 
     $newGenreBook->setRank($book['rank']); 
     $newGenreBook->setGenreId($genreId); 
     $newGenreBook->save(); 
     } 
}

口才假定primary key是id因此，所有你需要做的是設置主鍵像這樣：

protected $primaryKey = your primary key
