Laravel cache a query the includes Auth::id()-CodePudding

I have a Laravel application where all users credentials are stored in users table.

And I have multiple user roles, for each role there is a table in DB (admins, customers, ...) each one has different data.

I'm using Auth::user() multiple times in my application, and the query is executed only once on DB (as expected).

Example:

$user1 = Auth::user();
$user2 = Auth::user();
$user3 = Auth::user();
$user4 = Auth::user();

// The query is executed only once in DB.

When I'm trying to access admin data using Admin::where('user_id', Auth::id())->first() multiple queries are executed.

Example:

$user1 = Admin::where('user_id', Auth::id())->first();
$user2 = Admin::where('user_id', Auth::id())->first();
$user3 = Admin::where('user_id', Auth::id())->first();
$user4 = Admin::where('user_id', Auth::id())->first();

// 4 queries are executed.

I have tried to add a relationship to user model as follows:

// App\Models\User
class User extends Authenticatable
{
    ...

    public function admin()
    {
        return $this->belongsTo(Admin::class, 'id', 'user_id');
    }
}

When executing Auth::user()->admin() also 4 queries are executed.

I'm facing this problem in the model. I have this example model, where I need the agent to add an attribute:

// App\Models\Card

...
public function getCurrencyAttribute() {
    $user = Auth::user() // This query is executed only once for all rows.
    $admin = Admin::where('user_id', Auth::id()); // This query is executed for each row (if I have 100 rows, it's executed 100 times).
    ...
}
...

Is there a way to cache the query as Auth::user() is cached?

CodePudding user response：

first of all, Auth::user() is not cached, it's just stored in memory, and whenever you say Model::where('condition')->first(), you are telling the application to execute a query, so it will be executed, also when you say Auth::user()->admin(), you are calling it as a method, so it will return a query builder, you should call it as a property Auth::user()->admin, like this

try using load method, Auth::user()->load(['admin']), it should append admin object to the user object.

good luck ✌
