雄辩的ORM没有保存价值laravel

Question

我想更新使用雄辩我的数据，但它给了我一些错误：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'od_logo.id' in 'where clause' (SQL: select * from `od_logo` where `od_logo`.`id` = 1 limit 1) 

这里是我的代码：

$logo = Logo::find($id); 
$logo->logo_logoimg_name  = Input::get('logo_name'); 
$logo->logo_logoimg_path  = $logo_destinationPath . $logo_filename; 
$logo->logo_faviconimg_name = $favicon_destinationPath . $favicon_filename; 
$logo->save(); 

请找我哪里错了在此代码中

Answer 1

因为您的主键列不叫id（这是默认的Laravel假设），所以您必须在您的模型中指定它：

从

class Logo extends Eloquent { 
    protected $primaryKey = 'logo_id'; 
} 

报价：

Note: Eloquent will also assume that each table has a primary key column named id. You may define a primaryKey property to override this convention.
