select model B with model A column name condition in laravel model - sql

Question

I have two models with different name and columns but the purpose/data of the two models is the same, namely, it contains the employee's name, here the model
Employee
name
code
country
city
John
A1
USA
NYC
Doe
A2
USA
LA
New_Employee
v_fullname
v_code
v_country
v_city
Mark
ZZ1
USA
LS
Zuc
FF2
USA
LS
as you can see the column name is different but the purpose is identical. I want to select data from New_Employee but use column name from Employee, so the query will look like this
SELECT v_fullname as name, v_code as code, v_country as country, v_city as city
FROM New_Employee
WHERE name = 'Mark'
Sorry if my explanation is hard to understand, but here's the code I have tried
SyncEmployee model (this model is like a bridge connecting employee and new_employee model)
<?php
namespace App\Models;
use App\Models\Employee;
use App\Models\NewEmployee;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class SyncEmployee extends Model
{
use HasFactory;
protected $connection = 'mysql_2';
public const TABLE_NAME = 'new_employee';
public function index()
{
$data = NewEmployee::select('v_fullname as name, v_code as code, v_country as country, v_city as city')->get();
return view('view_name', compact('data'));
}
}
I thought with that code when I call SyncEmployee::where('code', '=', 'ZZ1') from controller, the result will
name
code
country
city
Mark
ZZ1
USA
LS
*The data is from New_Employee but the column name using Employee

You could attempt to use the ability to hide or append attributes at serialization to do most of the work for you. You would need to define accessors and mutators and define what is 'hidden' and 'appended' for serialization:
use Illuminate\Database\Eloquent\Casts\Attribute;
class NewEmployee extends Model
{
...
protected $table = 'new_employee';
protected $hidden = [
...
'v_fullname',
'v_code',
'v_country',
'v_city',
];
protected $appends = [
...
'name',
'code',
'country',
'city',
];
protected function name(): Attribute
{
return Attribute::make(
get: fn () => $this->attributes['v_fullname'] ?? null,
set: fn ($v) => $this->attributes['v_fullname'] = $v
);
}
...
}
If you are not using the Model's data after serialization you can still access these fields:
// will hit the accessor
$newEmployee->code;
// will hit the mutator
$newEmployee->code = 'blah';
