Laravel permission cache - laravel

Question

I am using my own implementation for user roles and permissions in laravel how to cache all the permissions and roles on user login and also to refresh the cache when new record is added.
My tables are users ,roles, permissions,permission_role,permission_user,role_user. This is my table structure
i have created on of the provider and added this code to boot method
Permission::get()->map(function ($permission)
{
Gate::define($permission->name, function ($user) use ($permission)
{
return $user->hasPermission($permission);
});
});
it is working fine but it is running the query each time which gets slowing down my application is there any way to cache all the permissions
here is my PermissionServiceProvider class
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Gate;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\Blade;
use App\Models\Permission;
class PermissionServiceProvider extends ServiceProvider
{
/**
* Bootstrap services.
*
* #return void
*/
public function boot()
{
if (Schema::hasTable('permissions'))
{
Permission::get()->map(function ($permission)
{
Gate::define($permission->name, function ($user) use ($permission)
{
return $user->hasPermission($permission);
});
});
}
Blade::directive('role', function ($role)
{
return "<?php if(Auth::user()->hasRole({$role})): ?>";
});
Blade::directive('endrole', function ($role)
{
return "<?php endif; ?>";
});
}
/**
* Register services.
*
* #return void
*/
public function register()
{
//
}
}
and finally inside the user model
public function hasPermission($permission)
{
return $this->hasPermissionThroughRole($permission) || (bool) $this->permissions->where('name',$permission->name)->count();
}
public function hasPermissionThroughRole($permission)
{
foreach($permission->roles as $role)
{
if($this->roles->contains($role))
{
return true;
}
}
return false;
}
and also here is my bit bucket repo

Answer 1

You could use Laravel model cache like shown in the following link:
https://laravel-news.com/laravel-model-caching
I would create a method for getting and caching the current users roles and permissions.
You can read more about Caching here:
https://laravel.com/docs/5.7/cache
I hope this helps
Update
Try something like this
if (Schema::hasTable('permissions') ) {
$userId = Auth::user()->id
return Cache::remember($this->cacheKey() . $userId . ':permissions', 60, function() use ($userId) {
return Permission::where('user_id', $userId)->get();
}
}
Then you just need to update your hasPermission() method to check the cache.
Also try to avoid map() as php takes a lot longer than sql

You can store your cache in service provider. I just sharing my method
$permissions = Cache::rememberForever('permissions', function () {
return Permission::get();
});
this will remember permissions with key name permissions forever until you change it
you can also remember this with specific time
$permissions = Cache::remember('permissions', 3600, function () {
return Permission::get();
});
I placed it in app service provider so that every time on app load it check if permissions found in cache then don't run the query and if not found then take it from DB
so your script could be like this after the cache part:
$permissions->map(function ($permission)
{
Gate::define($permission->name, function ($user) use ($permission)
{
return $user->hasPermission($permission);
});
});
find more on Laravel Documentation

finally I found the solution.
Artisan cache clear command is not working well.
Try to remove the cache on this folder.
storage/framework/cache/data
This should work for sure.
Good luck
