Solving company_id Assignment in ImportsAction with Filament

When working with Filament and having models that need to be restricted by a company scope, correctly assigning the company_id in records can be challenging, especially when handling bulk imports. In this article, I will share my experience and solution to this problem.

Context

In my system, I manage two main models:

Company Model: Represents the company a user belongs to.
Worker Model: Represents the workers within a company.

Although I do not use Filament's multi-tenancy system, all my queries are restricted by a scope to ensure that each user only sees records belonging to their company.

The Problem

Initially, I tried assigning the company_id to the worker in the WorkerObserver. To do this, I retrieved the company ID from the authenticated user using auth()->user()->company_id and assigned it in the creating event.

However, when performing imports, the process runs inside a Job, which prevents direct access to auth()->user(). I tried using lifehooks and the $import->user() property within the importer, but I couldn’t get it to work properly.

The Solution

To resolve this issue, I modified the import action in WorkerResource, adding a custom option to pass the authenticated user's company_id:

->headerActions([
    ImportAction::make()
        ->importer(WorkerImporter::class)
        ->options(['companyId' => auth()->user()->company_id])
        ->maxRows(10000)
])

Then, inside the WorkerImporter, I used the beforeFill() lifehook to assign the company_id if it was not already set:

protected function beforeFill(): void {
    if (!isset($this->data['company_id'])) {
        $this->data['company_id'] = $this->options['companyId'];
    }
}

Finally, in my WorkerObserver, I ensured that any manual record creation also assigns the company_id correctly:

public function creating(Worker $worker): void
{
    if (is_null($worker->company_id)) {
        $worker->company_id = auth()->user()->company_id ?? null;
    }
}

This allowed me to handle both imports and manual insertions or local seeders without issues.
