如何在laravel 5中创建全局缓存函数

Question

I need to use below code in a lot of route of my laravel 5 application so first: how to make it a simple function? second: how to cache result of this query for at least 10 minutes

$devices = \Auth::user()->devices()->whereNumber($number)->firstOrFail();

Answer 1

About your first question ,you could add another method to your User class like this -

public function MyFuncName($number){
    return $this->devices()->whereNumber($number)->firstOrFail();
}

if you want it to be cached for each user you could do it like this in Laravel 4 -

public function MyFuncName($number){
    return $this->devices()->whereNumber($number)->remember(10)->firstOrFail();
}

But in Laravel 5 you should do this like this:

public function myFuncName($number){
    return \Cache::remember('user_device_' . $number, 10, function() use ($number)
    {
        return $this->devices()->whereNumber($number)->firstOrFail();
    });
}

To call the function you would do

$devices = \Auth::user()->MyFuncName($number)

Forgot to mention that you must verify the user before as if \Auth::user() return null/false [user is not authenticated] then it will throw you an exception that this method doesnt exist
