Eloquent updateOrCreate不更新的问题

Question

我在使用 updateOrCreate 时遇到了麻烦。

下面的代码正在成功地创建一个新行，但是在更新现有行时，它根本不起作用！

comm_helpful::updateOrCreate(
           ['ID' => 1],
           ['time' => 3000]
        );

这正如我们所预料的那样:

comm_helpful::where('ID', 1)->update(['time' => 3000]);

我已经将上面的示例剥离到最低限度(这是调试的一部分) ，但它仍然不能工作！

Answer 1

Ok, after almost completely pulling my hair out; I found the problem where Eloquent is setting:

protected $primaryKey = 'id';

which is used on the update method and returned by getKeyName().

protected function setKeysForSaveQuery(Builder $query)
{

    $query->where($this->getKeyName(), '=', $this->getKeyForSaveQuery());

    return $query;
}

I then realised my 'id' on the tale was uppercase and not lower case!

I guess that means my answer is that I need to ensure I am using lowercase 'id' for the primary key or overriding it on the Model

protected $primaryKey = 'ID';
