php - 在 OR 上下文中使用多个 Laravel 作用域

Question

我的 Laravel 应用程序中有一个包含 start_date 和 end_date 属性的订阅模型。我创建了两个查询范围，scopeActive 和 scopeFuture 以(分别)查找事件订阅和 future 订阅。

我想知道如何在 OR 上下文中使用两个范围构建查询，以便我可以找到任何事件或 future 的订阅。

订阅模式

/**
 * Scope a query to only include active subscriptions.
 *
 * @param \Illuminate\Database\Eloquent\Builder $query
 * @return \Illuminate\Database\Eloquent\Builder
 */
public function scopeActive($query)
{
    return $query->where('start_date', '<', Carbon::now())
                 ->where('end_date', '>', Carbon::now());
}

/**
 * Scope a query to only include future subscriptions.
 *
 * @param \Illuminate\Database\Eloquent\Builder $query
 * @return \Illuminate\Database\Eloquent\Builder
 */
public function scopeFuture($query)
{
    return $query->where('start_date', '>', Carbon::now());
}


public function business()
{
    return $this->belongsTo('App\Business');
}

商业模式

.....
public function subscriptions()
{
    return $this->hasMany('App\Subscription');
}

用户模型

public function business()
{
    return $this->hasOne('App\Business');
}

Controller

Subscription::active()->get();

对于静态上下文尝试:

$subscriptions = Subscription::query()
    ->active()
    ->orWhere(function ($query) {
        $query->future();
    })
    ->get();

First call query() to prevent errors (because we may have a non-static method with "active" as name).

关系查询^{(按评论要求)}

$subscriptions = auth()->user()
    ->business()
    ->subscriptions()
    ->active()
    ->orWhere(function ($query) {
        $query->future();
    })
    ->get();

Note that above we don't need to call query() (because it's not from static-context).
