Laravel with() Eloquent 作为变量或另一个数组

Question

我有这个 Eloquent 查询想要按天、昨天、一周、上周、本月、上个月、今年、去年显示订单，这是我的代码，但是，它不起作用或确实有重新做代码的想法。在我的示例代码中，我不知道如何使用不同的参数将每个 with() 查询放入另一个查询中。请帮忙。

$product_orders = Product::where('status', 'active')
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', today());
    }])
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', Carbon::yesterday());
    }])
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', [now()->startOfWeek(), now()->endOfWeek()]);
    }])
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', [now()->subWeek()->startOfWeek(), now()->subWeek()->endOfWeek()]);
    }])
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->whereYear('created_at', '=', now()->year);
        $query->whereMonth('created_at', '=', now()->month);
    }])
    ->with(['order_detail' => function($query) {
        $fromDate = Carbon::now()->subMonth()->startOfMonth()->toDateString();
        $tillDate = Carbon::now()->subMonth()->endOfMonth()->toDateString();
        $parse_fromDate = Carbon::parse($fromDate.' 00:00:00');
        $parse_tillDate = Carbon::parse($tillDate.' 23:59:59');
        $query->with('order');
        $query->whereBetween('created_at',[$parse_fromDate,$parse_tillDate]);
    }])
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->whereYear('created_at', '>=', now()->year);
    }])
    ->with(['order_detail' => function($query) {
        $last_year = now()->year - 1;
        $query->with('order');
        $query->whereYear('created_at', '>=', $last_year);
    }])
    ->get();

Answer 1

使用这种方法，您实际上是用链中的下一个“with”覆盖每个“with”，因此实际执行的唯一内容是最后一个“with”。

您需要做的是将这些查询分解为具有单独结果集的单独查询，因为在核心上，您似乎希望从具有不同条件的多个不同查询中获得结果。

$todays_orders = Product::where('status', 'active')
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', today());
    }])
    ->get();

$yesterdays_orders = Product::where('status', 'active')
    ->with(['order_detail' => function($query) {
        $query->with('order');
        $query->where('created_at', '>=', Carbon::yesterday());
    }])
    ->get();

... etc...

使用查询：

$product_orders = Product::where('status', 'active')
   ->with([ 'order_detail' => function ($query) {
        $last_year = now()->year - 1;
        $query->whereYear('created_at', '>=', $last_year); 
    }, 'order_detail.order' ])->get();

$product_orders->each(function (Product $product) {
    $product->today_orders = $product->order_detail->where('created_at', '>=', Carbon::today());
    $product->today_orders = $product->order_detail->whereBetween('created_at', [ Carbon::yesterday(), Carbon::today() ]);
    $product->weeks_orders = $product->order_detail->whereBetween('created_at', [ Carbon::now()->startOfWeek(), Carbon::now()->endOfWeek() ]);
    $product->last_weeks_orders = $product->order_detail->whereBetween('created_at', [ Carbon::now()->subWeek()->startOfWeek(), Carbon::now()->subWeek()->endOfWeek() ]);
     // and so on
});

那么在您看来，每个产品应该具有在each中设置的属性

我通过在模型中使用过滤器创建了自己的解决方案

在控制器中

$product_orders = Product::where('status', 'active')
    ->with('order_detail_today', 'order_detail_yesterday', 'order_detail_this_week',
        'order_detail_last_week','order_detail_this_month', 'order_detail_last_month',
        'order_detail_this_year', 'order_detail_last_year')->get();

在模型中

public function order_detail_today()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->where('created_at', '>=', today());
    }
    public function order_detail_yesterday()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->where('created_at', '>=', Carbon::yesterday());
    }
    public function order_detail_this_week()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->where('created_at', '>=', [now()->startOfWeek(), now()->endOfWeek()]);
    }
    public function order_detail_last_week()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->where('created_at', '>=', [now()->subWeek()->startOfWeek(), now()->subWeek()->endOfWeek()]);
    }
    public function order_detail_this_month()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->whereYear('created_at', '=', now()->year)
            ->whereMonth('created_at', '=', now()->month);
    }
    public function order_detail_last_month()
    {
        $fromDate = Carbon::now()->subMonth()->startOfMonth()->toDateString();
        $tillDate = Carbon::now()->subMonth()->endOfMonth()->toDateString();
        $parse_fromDate = Carbon::parse($fromDate.' 00:00:00');
        $parse_tillDate = Carbon::parse($tillDate.' 23:59:59');
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->whereYear('created_at', '=', now()->year)
            ->whereBetween('created_at',[$parse_fromDate,$parse_tillDate]);
    }
    public function order_detail_this_year()
    {
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->whereYear('created_at', '>=', now()->year);
    }
    public function order_detail_last_year()
    {
        $last_year = now()->year - 1;
        return $this->hasMany('App\Order_detail','reference_number')
            ->where('order_type', '!=', 'package')
            ->with('order')
            ->whereYear('created_at', '>=', $last_year);
    }
