How to add multiple table relationship in laravel - laravel

Question

I have following tables and building query with Laravel relationship. In my panel, once the user logged I am getting user details & user business details but now I don't know how to get business types details too.
User Table:
id | business_id | username | email | password
1 1 john632 john#gmail.com *******
Users Business Table
id | user_id | business_type_id | business_name
1 1 2 Fortune
Business Types Table
id | business_type_name | description
1 Hotel Lorem Ipsum
2 Movie Lorem Ipsum
Models:
User
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Zizaco\Entrust\Traits\EntrustUserTrait;
use App\Notifications\ResetPassword as ResetPasswordNotification;
use Laravel\Passport\HasApiTokens;
use Illuminate\Database\Eloquent\SoftDeletes;
use Webpatser\Uuid\Uuid;
use App\RoleUser;
use App\UsersBusiness;
class User extends Authenticatable
{
use Notifiable;
use EntrustUserTrait;
use HasApiTokens;
use SoftDeletes, EntrustUserTrait {
SoftDeletes::restore as sfRestore;
EntrustUserTrait::restore as euRestore;
}
/**

*
* #var array
*/
protected $fillable = [
'business_id', 'username', 'email'
];
public function usersBusiness()
{
return $this->belongsTo('App\UsersBusiness', 'business_id', 'id');
}
}
UsersBusiness
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class UsersBusiness extends Model
{
use SoftDeletes;
/**

protected $table = 'tbl_users_business';
/**

protected $fillable = [
'user_id', 'business_type_id', 'business_name'
];
/**

*
* #var array
*/
protected $hidden = [
];
/**
* Dates to be treated as Carbon instances
*
* #var array
*/
public $dates = [
'deleted_at'
];
}
BusinessTypes
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class BusinessTypes extends Model
{
use SoftDeletes;
/**

protected $table = 'tbl_master_business_types';
/**

protected $fillable = [
'business_type_name', 'description'
];
/**

* #var array
*/
protected $hidden = [
];
/**
* Dates to be treated as Carbon instances
*
* #var array
*/
public $dates = [
'deleted_at'
];
}
Code:
$user = Auth::user();
$data['data'] = $user->load(['usersBusiness'] => function ($query) {
$query->select(["id", "user_id", "business_name"])->get();
}]);
I am getting below response data:

}
I want to add business types details too, so can you please guide me how to add relation for that table.
Thanks.

Answer 1

Create a belongsTo relation in your UserBusiness model like this
UserBusiness Model
public function businessType(){
return $this->belongsTo(BusinessType::class, 'business_type_id');
}
After that load it like this
$user = Auth::user();
$user->load(['usersBusiness.businessType']); //lazy loading
dd($user);
if you want userBusiness and their type only then
dd($user->usersBusiness);
Side Note: i think you don't need business_id in users table. Just keep user_id in userbusiness table and then add either hasOne ( if user can have only one business) or hasMany (if user can have more than one business) relation in User model for userBusness.

Answer 2

I recommend you to use API Resources.
For example, in my case I have ChannelItemResource.php:
public function toArray($request)
{
return [
'id' => $this->id,
'channel_id' => $this->channel_id,
'channel' => $this->channel->title,
'type' => $this->type,
'description' => $this->description,
'price' => $this->price,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
];
}
and ChannelResource.php:
return [
'id' => $this->id,
'title' => $this->title,
'user_id' => $this->user_id,
'description' => $this->description,
'type' => $this->type,
'url' => $this->url,
'ranking_total' => $this->ranking_total,
'ranking_flag' => $this->ranking_flag,
'ranking_country' => $this->ranking_country,
'thumbnail' => $this->thumbnail,
'state' => $this->state,
'hit' => $this->hit,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
'items' => ChannelItemResource::collection($this->items),
];
With this structure, you can easily include which relation you want and the result will be in JSON.
In Controller use:
public function all(Request $request)
{
return new ChannelsResource(Channel::where("state", "active")->orderBy('id', 'desc')->paginate(30));
}
