Filament Importing MorphTo relationship

Certainly! Here's how you can approach building an importer for a MorphTo relationship using Filament in Laravel.

Understanding the Problem

• Customer has an Address relationship, where Address is morphed to various models (MorphTo).
• You want to import data (presumably from CSV/Excel) such that addresses are correctly associated with the customers via the MorphTo.

Solution Overview

When importing, you need to ensure:

• The addressable_id and addressable_type fields are set correctly in the addresses table.
• The import process knows which model (in this case Customer) the address belongs to.

Assuming your addresses table looks like:

Schema::create('addresses', function (Blueprint $table) {
    $table->id();
    $table->morphs('addressable'); // addressable_id, addressable_type
    $table->string('address');
    // ... other fields
});

And your Customer model:

public function addresses()
{
    return $this->morphMany(Address::class, 'addressable');
}

Example Importer Using maatwebsite/excel with Filament

Let's use maatwebsite/excel, which is a common package for importing/excel data in Laravel ecosystems. If you're using Filament Excel, it leverages this under the hood.

AddressImport.php:

namespace App\Imports;

use App\Models\Customer;
use App\Models\Address;
use Maatwebsite\Excel\Row;
use Maatwebsite\Excel\Concerns\OnEachRow;
use Maatwebsite\Excel\Concerns\WithHeadingRow;

class AddressImport implements OnEachRow, WithHeadingRow
{
    public function onRow(Row $row)
    {
        $row = $row->toArray();

        // Lookup Customer
        $customer = Customer::where('email', $row['customer_email'])->first();

        if ($customer) {
            $customer->addresses()->create([
                'address' => $row['address'],
                // add other address fields
            ]);
        }
    }
}

Sample CSV Format:

customer_email,address
[email protected],123 Main St
[email protected],456 Elm Ave

When the import runs:

• It locates the customer by email.
• Calls $customer->addresses()->create([..]), which will automatically set the correct addressable_id and addressable_type.

Using Filament Plugin (eg. Filament Excel)

If you're using Filament Excel:

In your Filament Resource for Address, set up the importer similarly.

use App\Imports\AddressImport;

public static function getImportAction(): ImportAction
{
    return ImportAction::make()
        ->importer(AddressImport::class);
}

Tips

• Make sure your input file uniquely identifies the Customer (or any morphable model).
• If addresses can belong to other models, expand logic to check for different model types using a model_type column in your CSV.

Summary

1. In your importer, loop through rows.
2. Lookup the related model (Customer).
3. Use the relationship ($customer->addresses()->create()) to create the address. This sets the MorphTo fields automatically.

If you need to support multiple models (not just Customer), add logic to detect addressable_type from your import file.
