Question

我想操纵模型中的数据我该怎么做？我正在尝试这个，但它不起作用：

class Character extends Model
{
    //Get players by level
    public function scopeGetPlayersByLevel($query){
       $output = $query->orderBy('level', 'desc')->get();
       $output->classid = 100;
       return $output;
    }

    //Get online status
    public function account(){
        $account = $this->belongsTo(Account::class, 'account_name', 'username');
        $account->online = $account->online == 1 ? 'Online' : 'Offline';
        return $account;
    }
}

Answer 1

Account模型中的

Define an accessor：

public function getOnlineAttribute($value)
{
    return $value === 1 ? 'Online' : 'Offline';
}

Answer 2

试试这个：

a）定义帐户模型的关系

b）创建一个访问者（我称之为getAccountStrAttribute，这意味着你这样称呼它：$acc->account_str）。

c）胜利

class Character extends Model
{
    // Relationship defined
    public function account() {
      return $query->belongsTo(Account::class, 'account_name', 'username');
    }

    //Get online status
    public function getAccountStrAttribute(){
        return $this->account->online ? 'Online' : 'Offline';
    }

    // I can't figure out what you want this function to return/do :/
    //Get players by level
    public function scopeGetPlayersByLevel($query){
       $output = $query->orderBy('level', 'desc')->get();
       $output->classid = 100;
       return $output;
    }
}
