Laravel 5 - get ID by other field properly

Question

I want to get the ID of a user in a middleware by searching with his email. I thought about doing it like this in one of two ways.

First, creating a function in the model User :

public function getIdByMail($query, $q) {
    return $query->select('id')->where('email', $q);
}

Second, using this function in my middleware

use App\User;
...
$user = User::getIdByMail($user_id);

And it doesn't work, nor am I even sure it's the right way...

Answer 1

This should do it. No need for extra methods in model. Eloquent makes everything pretty simple.

$id = User::where('email', $email)->first()->id;

Answer 2

To interact with the DB only from the model than

$post= \App\Models\Category::where([
        ['name' , $name]])->first()->id;
