Php Laravel 5.5属于枢轴条件下的气孔

我有三个模型，

Clinic

、

Department

和

ClinicDepartment

，并且使用

ClinicDepartment

的表作为透视表，从

ClinicDepartment

到

Department

有

belongstomy

关系，称为

departments

，但是当我使用这个关系时，来自

临床科室的范围

不适用于查询

我决定让Pivot模型调用ClinicDepartmentPivot，并将这些作用域应用于Pivot，但运气不好

诊所模式：

class Clinic extends Model
{
    use SoftDeletes, ActiveOnly, HasParent;

    public function departments()
    {
        return $this->belongsToMany(Department::class, 'clinic_departments', 'clinic_id', 'department_id')->using(ClinicDepartmentPivot::class);
    }
}

部门模式：

class Department extends Model
{
    use SoftDeletes, ActiveOnly;

    public function clinics()
    {
        return $this->belongsToMany(Clinic::class, 'clinic_departments', 'department_id', 'clinic_id')->using(ClinicDepartmentPivot::class);
    }
}

临床科室枢轴模型：

class ClinicDepartmentPivot extends Pivot
{
    use ActiveOnly, SoftDeletes;
}

ActiveOnlyScope：

class ActiveOnlyScope implements Scope
{
    public function apply(Builder $builder, Model $model)
    {
        $builder->where($model->getTable() . '.is_active', true);
    }
}

所以基本上我想将全局作用域应用于透视模型，所以当我尝试获取科室的诊所时，它应该检查-is ClinicDepartment has

is_active=1

，并且没有删除

UPD 1 我的范围特征如下所示：

trait ActiveOnly
{
    public static function bootActiveOnly()
    {
        if (!Auth::guard('admin')->check() && strpos(request()->getRequestUri(), 'admin') === false) {
            static::addGlobalScope(new ActiveOnlyScope);
        }
    }
}

select `clinics`.*, `clinic_departments`.`department_id` as `pivot_department_id`, `clinic_departments`.`clinic_id` as `pivot_clinic_id` from `clinics` inner join `clinic_departments` on `clinics`.`id` = `clinic_departments`.`clinic_id` where (`clinic_departments`.`is_active` = 1 and `clinic_departments`.`deleted_at` is null)

可供任何型号使用。

您缺少以下内容：

若要将全局范围指定给模型，应重写给定的 模型的引导方法，并使用

addGlobalScope

方法

您的模型应如下所示：

class Clinic extends Model
{
    use SoftDeletes, ActiveOnly, HasParent;

    protected static function boot()
    {
        parent::boot();

        static::addGlobalScope(new ActiveOnlyScope);
    }

    public function departments()
    {
        return $this->belongsToMany(Department::class, 'clinic_departments', 'clinic_id', 'department_id')->using(ClinicDepartmentPivot::class);
    }
}



class Department extends Model
{
    use SoftDeletes, ActiveOnly;

    protected static function boot()
    {
        parent::boot();

        static::addGlobalScope(new ActiveOnlyScope);
    }

    public function clinics()
    {
        return $this->belongsToMany(Clinic::class, 'clinic_departments', 'department_id', 'clinic_id')->using(ClinicDepartmentPivot::class);
    }
}

好的，通过一些变通方法，我终于找到了一个看起来不那么零碎的解决方案）

实际查询如下所示：

trait ActiveOnly
{
    public static function bootActiveOnly()
    {
        if (!Auth::guard('admin')->check() && strpos(request()->getRequestUri(), 'admin') === false) {
            static::addGlobalScope(new ActiveOnlyScope);
        }
    }
}

select `clinics`.*, `clinic_departments`.`department_id` as `pivot_department_id`, `clinic_departments`.`clinic_id` as `pivot_clinic_id` from `clinics` inner join `clinic_departments` on `clinics`.`id` = `clinic_departments`.`clinic_id` where (`clinic_departments`.`is_active` = 1 and `clinic_departments`.`deleted_at` is null)

谢谢大家的想法。

我知道范围，我正在使用Trait来分配全局范围，

ActiveOnly

-将全局范围分配给模型的Trait。这就像拉威尔的性格。问题不在于如何在模型中使用作用域，而在于如何在透视模型中使用作用域。
