Editing Records

When editing record in Aureus ERP using Filament, you may need to validate and modify form data before saving changes to the database. Filament provides the mutateFormDataBeforeSave() method to handle this modification.

This method allows you to:

• Sanitize or modify input values before saving.
• Ensure business rules are followed when updating post details.

Usage Example

Basic Implementation

Modify the form data to prevent changes to certain fields:

protected function mutateFormDataBeforeSave(array $data): array
{
    return $data;
}

Mutating Data in Modal Actions

If you're using modal actions instead of standard edit pages, you can modify form data within modal-based actions:

use Filament\Actions\EditAction;

EditAction::make()
    ->mutateFormDataUsing(fn (array $data) => [
        ...$data,
        'updated_by' => auth()->id(),
    ]);

Example: Implementing EditPost

A EditPost class can be implemented using Filament’s EditRecord.

<?php

namespace Webkul\Blog\Filament\Resources\PostResource\Pages;

use Filament\Actions;
use Filament\Forms;
use Filament\Notifications\Notification;
use Filament\Pages\SubNavigationPosition;
use Filament\Resources\Pages\EditRecord;
use Illuminate\Support\Facades\Auth;
use Webkul\Chatter\Filament\Actions\ChatterAction;
use Webkul\Blog\Filament\Resources\PostResource;

class EditPost extends EditRecord
{
    protected static string $resource = PostResource::class;

    public function getSubNavigationPosition(): SubNavigationPosition
    {
        return SubNavigationPosition::Top;
    }

    protected function getRedirectUrl(): string
    {
        return $this->getResource()::getUrl('view', ['record' => $this->getRecord()]);
    }

    protected function getSavedNotification(): Notification
    {
        return Notification::make()
            ->success()
            ->title(__('Post updated'))
            ->body(__('Post has been updated successfully.'));
    }

    protected function mutateFormDataBeforeSave(array $data): array
    {
        $user = Auth::user();

        $data['updated_by'] = $user->id;
        $data['updated_at'] = now();

        return $data;
    }

    protected function getHeaderActions(): array
    {
        return [
            ChatterAction::make()->setResource(static::$resource),
                        Actions\Action::make('publish')
                ->label(__('Publish'))
                ->color('primary')
                ->icon('heroicon-o-check-badge')
                ->visible(fn($record) => $record->status == PostStatus::UNPUBLISHED->value)
                ->action(function ($record) {
                    $record->update(['status' => PostStatus::PUBLISHED->value])
                }),
            Actions\Action::make('un_publish')
                ->label(__('Unpublish'))
                ->color('primary')
                ->icon('heroicon-o-x-circle')
                ->visible(fn($record) => $record->status == PostStatus::PUBLISHED->value)
                ->action(function ($record) {
                    $record->update(['status' => PostStatus::UNPUBLISHED->value])
                }),
            Actions\DeleteAction::make()
                ->successNotification(
                    Notification::make()
                        ->success()
                        ->title(__('Post Deleted'))
                        ->body(__('Post has been deleted successfully.')),
                ),
        ];
    }

    protected function afterSave(): void
    {
        // This block of code executes when the record has been saved.
    }
}

Explanation

• Handles Post Editing: This class ensures post updates follow the necessary business rules.
• Data Mutation: Assigns the updated_by field and prevents unauthorized users from modifying certain fields.
• Actions: Includes publish or unpublish, deletion, and Chatter integration for discussions.
• Redirection & Notifications: Redirects to the post view and notifies the user on successful update.
