Roles/Permissions: Manage Employees

Premium
9 min read

Next on our list - separating user roles. In our system, we need admins to manage the system settings and employees, while the employees themselves can only manage customers and nothing else:

In this lesson, we will do the following:

  • Create roles Model and Database structure
  • Create a user management page (CRUD)
  • Add employees to our Customers' table and form for admins to manage
  • Add employee changes to our customer history
  • Add an additional tab in Customers for My Customers - customers assigned to the employee

Creating Roles Model and Database structure

Let's start by creating our migration file:

Migration

Schema::create('roles', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->timestamps();
});

Then, we can fill out our Model:

app/Models/Role.php

class Role extends Model
{
    protected $fillable = ['name'];
}

Of course, we should also...

app/Models/Customer.php

if ($customer->employee_id !== $lastLog) {

Looks like this line should be:

if ($customer->employee_id !== $lastLog->employee_id) {

app/Filament/Resources/CustomerResource/Pages/ListCustomers.php

with filter query:

if (!auth()->user()->isAdmin()) {
    $tabs['my'] = Tab::make('My Customers')
        ->badge(Customer::where('employee_id', auth()->id())->count())
        ->modifyQueryUsing(function ($query) {
            return $query->where('employee_id', auth()->id());
        });
}

Hi! Thank you and the team for the amazing work! Just a quick questions if i may.

in the following example, shouldn't the code be:

// From
if ($customer->employee_id !== $lastLog->employee_id) {
// To
if ($customer->employee_id !== $lastLog?->employee_id) {

Since we're only looking for records where employee_id is not null which may result in $lastLog being null.

Maybe im wrong tho. Keep up the good work!

Hi, this was updated yesterday as indeed - there was a mistake on our end!

We also fixed My Customers tab filtration

Oh for me it still says "$lastLog->employee_id" without the nullsafe operator. But thank you for confirming!

Hm, did you encounter an issue with nullsafe? I have not seen it, so did not add it! But definitely can add a check for it

i did encounter a problem without using the nullsafe on $lastLog->employee_id. In the course it says to use "$lastLog->employee_id" but i think it should say "$lastLog?->employee_id"

self::updated(function (Customer $customer) {
    // this could return null
        $lastLog = $customer->pipelineStageLogs()->whereNotNull('employee_id')->latest()->first();
 
    // in the case that $lastLog is null, employee_id is not accessible.
    // this is why i added a nullsafe ($lastLog?->employee_id)
        if ($customer->employee_id !== $lastLog->employee_id) {
            $customer->pipelineStageLogs()->create([
            //
        }
    });

But maybe i did something wrong before this.

Hm... Maybe I had a different structure there and didn't see the issue. In any case, added a check! Thanks for reporting

Could we simplify using:

self::updated(function (Customer $customer) {
    if ($customer->wasChanged('employee_id')) {
        $customer->pipelineStageLogs()->create([
            //
        }
});

I choose Blue_Moonie solution, is more clear and work. The alternative is to modify the seeder and associate, during the creation of the customer, an employee (a solution I do not like)
