Php 在appends属性中获取服务

我有一个模型，看起来像这样：

奖励获得模式：

class RewardsEarnedModel extends BaseModel{

    protected $appends = ['readable_date'];

    public function getReadableDateAttribute(){
        // How do I access the User Service?
        return $this->userService->dateTime($this->attributes['created_at'])->readableDate;
    }

    public function scopeSums($query, User $user, $offset = 0, $limit = 50){
        return $query-> /* add items here (snipped) */;
    }

}

public function getRewards(Request $request, User $user, $date = null){
    $rewards = new RewardsEarnedModel;
    $rewards = $rewards->Sums($user);

    $sums = $rewards->get()->toArray();
}

namespace App\Services;
class User {
    use Time;
}

namespace App\Traits;
trait Time{
    public function dateTime($datetime = null){
        /* Snipped code */
    }
}

然后，我从控制器运行模型，如下所示：

奖励管理员：

class RewardsEarnedModel extends BaseModel{

    protected $appends = ['readable_date'];

    public function getReadableDateAttribute(){
        // How do I access the User Service?
        return $this->userService->dateTime($this->attributes['created_at'])->readableDate;
    }

    public function scopeSums($query, User $user, $offset = 0, $limit = 50){
        return $query-> /* add items here (snipped) */;
    }

}

public function getRewards(Request $request, User $user, $date = null){
    $rewards = new RewardsEarnedModel;
    $rewards = $rewards->Sums($user);

    $sums = $rewards->get()->toArray();
}

namespace App\Services;
class User {
    use Time;
}

namespace App\Traits;
trait Time{
    public function dateTime($datetime = null){
        /* Snipped code */
    }
}

我的

用户

服务类附带了一个

时间

特征。在这个特性中有一个函数

dateTime

，我想从我的

getReadableDateAttribute

方法访问它，但我似乎不能这样做。如何从我的

用户

服务访问它

用户服务：

class RewardsEarnedModel extends BaseModel{

    protected $appends = ['readable_date'];

    public function getReadableDateAttribute(){
        // How do I access the User Service?
        return $this->userService->dateTime($this->attributes['created_at'])->readableDate;
    }

    public function scopeSums($query, User $user, $offset = 0, $limit = 50){
        return $query-> /* add items here (snipped) */;
    }

}

public function getRewards(Request $request, User $user, $date = null){
    $rewards = new RewardsEarnedModel;
    $rewards = $rewards->Sums($user);

    $sums = $rewards->get()->toArray();
}

namespace App\Services;
class User {
    use Time;
}

namespace App\Traits;
trait Time{
    public function dateTime($datetime = null){
        /* Snipped code */
    }
}

时间特征：

class RewardsEarnedModel extends BaseModel{

    protected $appends = ['readable_date'];

    public function getReadableDateAttribute(){
        // How do I access the User Service?
        return $this->userService->dateTime($this->attributes['created_at'])->readableDate;
    }

    public function scopeSums($query, User $user, $offset = 0, $limit = 50){
        return $query-> /* add items here (snipped) */;
    }

}

public function getRewards(Request $request, User $user, $date = null){
    $rewards = new RewardsEarnedModel;
    $rewards = $rewards->Sums($user);

    $sums = $rewards->get()->toArray();
}

namespace App\Services;
class User {
    use Time;
}

namespace App\Traits;
trait Time{
    public function dateTime($datetime = null){
        /* Snipped code */
    }
}

---

我可以通过执行

app（）->User

来访问用户服务，以下是最终结果：

public function getReadableDateAttribute(){
    return app()->User->dateTime($this->attributes['created_at'])->readableDate;
}

---

$user->readable\u date

是否有效？

$user->readable\u date

不是一个选项。我要做的是格式化用户保存时区中数据库中的值，只需将该特征放入用户模型中，即可从该模型中使用它。然后使用

$this->dateTime

即可毫无问题地使用它。
