@JellyBook 为什么我用sudo -Hu www-data ssh-keygen -t rsa生成的公钥在/home/www-data/.ssh下，不是在/var/www/.ssh

请问大神，我想用Eloquent对象生成一个空QueryBuilder对象，这是为了拼接条件查询用。
比如

    $builder = Product::where('id','>=',0);
    $btime = 0;
    $etime = 100;
    $keyword = 'hello';

    if(!empty($btime) && !empty($etime)){
        $builder->whereBetween('created_at',[$btime,$etime]);
    }

    if(!empty($keyword)){
        $builder->where(function($query)use($keyword){
            $query->orWhere('name','like','%'.$keyword.'%')->orWhere('email','like','%'.$keyword.'%');
        });
    }

    $Data = $builder->get();

如上面所示的例子，我想生成一个空的QueryBuilder对象而不是通过where('status','>',0),这样看起来怪怪的。

vue.js是不支持低于IE8，如果还想使用MVVM的话，可以使用avalon.js

你这个不能合并吧，因为你$goods里有两条数据了。你这是一对多，不是一对一，如果一对一就可以合并成一个数据
