Description

When using Castable classes and providing arguments in the eloquent model's $casts definition, the property is not being casted to a phpstan type.

Model property casting has been handled in #1333.

How to replicate

Implement a castable class as defined here and provide an argument via the model's $casts[].

use App\Models\Address;
 
protected $casts = [
    'address' => Address::class.':argument',
];

What error are you getting?

[attac-t]

Let's say that the Address value object has a method getCountryName() and that address is a string database column in the users table. For $user->address->getCountryName(), larastan gives a cannot call method getCountryName() on string. error. This only happens if the ':argument' is present in the $casts.

I see.

@erikgaal Can you take a look at this please?

This should be covered by the 'secret' => Hash::class . ':sha256' test case, but I will investigate.

Getting a similar error when I updated from 2.2.9 to 2.4.0 and using cknow/laravel-money casters. Example:

use Cknow\Money\Casts\MoneyIntegerCast;

protected $casts = [
        'amount' => MoneyIntegerCast::class.':currency_code',
];

And when calling it like $model->amount->formatByDecimal(), PHPStan says the following:

Cannot call method formatByDecimal() on int.
