如何在laravel中获得关系

Question

I have three model : Manager ,Vendor, Banquet and the relationship is :

• manager has one vendor
• vendor has many banquet

How to get the all manager with all relation in laravel orm?

$manager = Manager::where('active',1)->get();
$vendor = $manager->vendor()->get();// -- dose not work! 
$banquet =  $vendor->banquet()->get();// -- dose not work! 

Manager model:

class Manager extends Model{
     protected $table = 'manager';
     protected $primaryKey = 'id';

     public function vendor(){
     return $this->hasOne('ACME\Entities\Vendor','managerId','id');
   }
}

Here is the model

Vendor model:

class Vendor extends Model{
    protected $table = 'vendor';
    protected $primaryKey = 'id';

    public function manager(){
      return $this->belongsTo('ACME\Entities\Manager_V','id','managerId');
    }

    public function banquet(){
        return $this->hasMany('ACME\Entities\V_Banquet' ,'vendorId' ,'id');
    }
}

Banquet model:

class Banquet extends Model{
    protected $table = 'banquet';
    protected $primaryKey ='id';

    public function vendor()
    {
        return $this->belongsTo('ACME\Entities\Vendor' ,'vendorId' ,'id');
    }
}

Answer 1

Use with method

$manager =  Manager::with(['vendor','vendor.banquet'])->where('active',1)->get();

You will be able to get data as

$banquet = $manager->vendor->banquet;
// $banquet will be array of banquet model objects

Remember hasMany return array, hasOne return Object and belongsTo return Object.
