Question

我尝试使用关系从模型中检索某些结果，并尝试对该关系应用某些过滤器。

以下是模型：

<?php namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class UserProduct extends Model
{

    protected $primaryKey = null;
    public $incrementing = false;
    protected $table = "user_product";

    public $fillable = [
        ...
        "product_id",
        "user_id",
        "is_featured",
        "is_hidden_from_latest"
        ...
    ];

    public function product()
    {
        return $this->belongsTo("\\App\\Models\\Product", "product_id", "id");
    }

    ...

}

以下是相关型号：

<?php namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $table = "products";

    public $timestamps = false;

    public $fillable = [
        ...
    ];

    public function userProduct()
    {
        return $this->hasOne("\\App\\Models\\UserProduct", "product_id", "id");
    }

    ...

}

以下是UserProduct模型和产品关系的查询：

$user_products = UserProduct::with("product")
    ->whereHas("product", function($q) {
        $q->where("product_status", "live")
            ->where("parent_child", "Child");
    })->where("is_featured", 1)
        ->orWhere("is_hidden_from_latest", 0)
        ->orderBy("is_featured", "desc")
        ->orderBy("updated_at")
        ->get();

问题在于whereHas子查询似乎无法过滤任何内容，无论要与每个product_status和parent_child使用的值进行比较。

有什么东西我不能正确做到吗？

更新：似乎游戏破坏者最后是这两个where()声明：

....
->where("is_featured", 1)
->orWhere("is_hidden_from_latest", 0)
....

，更具体地说是orWhere()语句。

Answer 1

试试这种方式

$user_products = UserProduct::with("product")
->whereHas("product", function($q) {
    $q->where("product_status", "live")
    ->where("parent_child", "Child");
})
->where(function ($query) {
    $query->where("is_featured", 1)
    ->orWhere("is_hidden_from_latest", 0);
})
->orderBy("is_featured")
->orderBy("updated_at")
->get();

Answer 2

我刚刚删除了where("is_featured", 1)并将其替换为where("is_hidden_from_latest", 0)，因为我总是按is_featured排序结果。

whereHas()子查询正常工作。：）

Laravel 5：雄辩，其中子查询没有过滤结果
