How to make multiple roles in Spatie Laravel package? - laravel

Question

Is possible with Spatie's laravel-permission package to achieve something like what Facebook have with their permissions for pages?
Case study,
On Facebook you can create a page, then automatically you'll become Admin (assuming it's a role) of that page.
Then you can invite you friend and make him/her a Publisher role
After that, your friend can also invite you to their Page and make you an Editor ( that's another role for you)
so at the end you will have two roles for two different profiles/Pages.
I want to achieve something like that on my app.
EDIT
what i know for now is that i can use:
$user->assignRole('editor');
and i can check if the user has a roles with :
$user->hasRole('writer')
But the thing is how do i link that role with the page that i want them to manage?
Like if you have admin role in one page and editor role in another page.
and if you just check if $user->hasRole('admin') the results will always be true. so i want to know if there is anything i can do to assign and also check which page are you admin for.
I hope i am making sense.

Assuming your table structure looks like this:
Pages table
|---------------------|------------------|------------------|------------------|
| id | name | created_at | updated_at |
|---------------------|------------------|------------------|------------------|
| 12 | PHP masters | 2019-02-31 | 2019-03-12 |
|---------------------|------------------|------------------|------------------|
Pages admin
|---------------------|------------------|------------------|------------------|
| id | page_id | role_id | user_id |
|---------------------|------------------|------------------|------------------|
| 1 | 12 | 2 | 2 |
|---------------------|------------------|------------------|------------------|
Roles table
|---------------------|------------------|------------------|------------------|
| id | name | created_at | updated_at |
|---------------------|------------------|------------------|------------------|
| 12 | Editor | 2019-02-31 | 2019-03-12 |
|---------------------|------------------|------------------|------------------|
| 12 | System Admin | 2019-02-31 | 2019-03-12 |
|---------------------|------------------|------------------|------------------|
| 12 | Page Admin | 2019-02-31 | 2019-03-12 |
|---------------------|------------------|------------------|------------------|
Now inside User model add this method
#do not forget to import Roles
#use Spatie\Permission\Models\Role;
public function can_manage($page_id) : bool;
{
#Backdoor for the system admin
if ($this->hasRole(['System Admin'])) {
return true;
}
#now we check if the user has the role for that page
$role = Role::select('name')
->join("page_admins", 'page_admins.role_id', '=', 'roles.id')
->where("page_id", $page_id)
->where("user_id", $this->id)
->first();
#return true if roles was found
if (!empty($role)) {
return true;
}
#else false
return false;
}
Lastly if you want to check if the user can access the page's admin you use:
#for jwt-auth
#$user = $request->user();
if ( $user->can_manage($page_id) )
{
#then do you things
}
Now that you saw how to check if someone is among page administration, you can get creative with that. you can create a method that :
#Get user role in the page
#etc

Yes. You can create the roles with artisan and assign them in php.
php artisan permission:create-role editor
php artisan permission:create-role publisher
$user->assignRole(['editor', 'publisher']);
all of this is easily available in the documentation
