类型提示雄辩模型

Question

I am trying to write good code, and part of that is type hinting to make it easier for work down the line and to force expectations.

This may seem a little contrived, but its more of a proof of concept for me.

I am writing a class to take a TSV file split on tabs and insert into my Model. In my constructor I was asking for:

Illuminate\Database\Eloquent\Model

To which I passed:

new \App\Model()

And finally the error response of:

instance of App\Model given

Clearly I have done something wrong, but I do not want to force usage of App\Model, how can I generically ask for an eloquent model?

Edit for more information:

To make it more clear, I am using Laravel 5, the models are created via artisan make:model. The constructor is as follows:

function __construct ($resource, Illuminate\Database\Eloquent\Model $model, $skip = 0)

And the Model I am using (for my movie table) is:

use Illuminate\Database\Eloquent\Model;

class Movie extends Model {

In your type hint, preface the FQCN with a backslash:

function __construct ($resource, \Illuminate\Database\Eloquent\Model $model, $skip = 0)

Either that, or add the use statement to your class:

use Illuminate\Database\Eloquent\Model;

class MyClass {
    function __construct ($resource, Model $model, $skip = 0) {
        //
    }
}
