Laravel Eloquent Find Not Working When Given String Model

Question

I have A Model In Laravel stored in variable as String.

$model = "App\Models\City";

What I want is

$model::find(1) to fetch the City with ID of 1

But It's not working as it is expected. However, when I do

City::find(1)

Not using the $model variable. I can fetch my expected result.

Anyone?

From the string name of a class, can I get a static variable? — LF-DevJourney

You could resolve the class out of service container

$model = app("App\Models\City");
$model::find(1);

You can use this, you can refer How can I call a static method on a variable class? for more.

$city = call_user_func($class . '::find', 1);

You can use call_user_func

Try this:

$model = "App\Models\City";
$id =1
$city = call_user_func(array($model, 'find'), $id);
