php - Can I cast one Eloquent model to another?
Get the solution ↓↓↓
In eloquent you can have different models operating on a same table. So, is it possible to switch an object from one Model to another in a runtime. Assuming that we have three classes:
Product extends Model
ProductSet extends Product
SimpleProduct extends Product
The difference between ProductSet and a SimpleProduct is columncomplex which has 'true' in it for a ProductSet and 'false' for a SimpleProduct.
ProductSet and a SimpleProduct models have Scopes applied to them so thatProductSet::all() will get only sets, andSimpleProduct::all() will get only a simple products.
Parent model however allow us to get both types of products viaProduct::all()
so, is it possible to go through all instances of Product class and switch them to their higher level models at runtime based on a value of propertycomplex ?
Answer
Solution:
Since you're already extending the class which holds the same props as the parent. You can loop over anyproduct collection and get all the attributes throughgetAttributes() method and pass to the parent. Because each of your model is extending EloquentModel which accepts attribute in theconstructor and fills its attribute.
Following example extends the defaultUser class and converts back to the Parent class
<?php
namespace App;
class Admin extends User {}
Get allAdmins and convert them toUser
$admins = \App\Admin::all();
$users = [];
foreach ($admins as $admin) {
$users[] = new \App\User($admin->getAttributes());
}
dd(collect($users));

Solution:
Yes you can do that, Based on the prop you have to create object of that specific class
