要像hasMany那样连接多个表（模型），在Laravel中可能无法开箱即用。
不过，如果你真的需要把它们都结合起来，我做过一次，但并不漂亮。
首先将以下内容添加到示例中的每个App\Records\Model（绿色）

class Green extends Model
{
   protected $table = 'GreenRecords';

   ....
   ....

   // this is to append/add extra fields into your model
   // that not exist inside the table it self
   protected $appends = [
        'product_data',
        'stuffs',
   ];

   // relationship to App\Models\Customer
   public function customer()
   {
        return $this->belongsTo(Customer::class, 'customerid', 'id');
   }

   // you can use it later as Green::query()->customer($id)->get()
   public function scopeCustomer($query, $id)
   {
        return $query->where('customerid', $id);
   }
   
   // you can add here as many data as you like from table GreenRecords, 
   // this will make Green Orange and Blue as if they have common fields
   // you can also separate them by adding add each custom field to $appends
   public function getProductDataAttribute()
   {
        return [
           'name' => $this->name,
           'color' => $this->color,
           'stuffs' => $this->stuffs,
           'other_stuffs' => $this->other_stuffs,
        ];
   }
   public function getStuffsAttribute()
   {
        return $this->stuffs;
   }
   
}

现在是客户模型

class Customer extends Model
{
    // your Customer relation to Orange
    public function oranges()
    {
       return $this->hasMany(Orange::class, 'cid', 'id');
    }

    // your Customer relation to Green
    public function greens()
    {
       return $this->hasMany(Green::class, 'customerid', 'id');
    }

    public function getRecords(): Collection
    {
       // we can not use collection merge due to same 'id' in Orange and Green
       $collections = collect();

       if ($oranges = Orange::query()
           ->customer($this->id)
           ->get()
       ) {
           foreach ($oranges as $record) {
               $collections->push($record);
           }
       }

       if ($greens = Green::query()
           ->customer($this->id)
           ->get()
        ) {
           foreach ($greens as $record) {
               $collections->push($record);
           }
       }

       return $collections;
    }
}

所以现在你可以

$customer = Customer::find(3);
$records = $customer->getRecords(); // result will be a collection

在刀片内部，您可以访问它们

@foreach ($records as $record) 
   {{ $record->stuffs }}
   {{ $records->product_data['other_stuffs'] }}
@endforeach

可以对集合进行筛选和排序

$records->where('product_data.stuffs', 'abc')->sortBy('name');

这里唯一的问题是记录id，其中橙色可以与绿色和蓝色具有相同的id。
最好是在橙绿和蓝$table->uuid('record_id')->nullable();中添加新字段
希望这能帮到你。
