Filament-Generate-Helpers

Effortlessly create reusable form fields and table column helpers for Filament resources based on Laravel models. This package is not just about generating code—it introduces a methodology for managing forms and tables in your Filament projects, making them reusable and easier to maintain.

Why Use This Package?

When building a Filament project, it's common to encounter repetitive definitions for forms and tables in various contexts, such as:

• Resources: A resource's form and table are defined independently.
• Relation Managers: You might reuse a form or table inside a relation manager.
• Table widgets or Custom Pages: Forms and tables are often replicated here.
• Select Forms (createOptionForm): Similar forms might be required when creating options in a Select field.

The Problem

If a change is required in the form or table (e.g., adding a new field or column), you have to update it in multiple places. This is time-consuming, error-prone, and violates the DRY (Don't Repeat Yourself) principle.

The Solution

This package provides a systematic approach:

• Centralizes the definitions of form fields and table columns in reusable traits and helper classes.
• Allows you to make changes in one place and have them reflected everywhere.

Features

• Reusable Form Fields: Generate reusable form fields organized into a trait.
• Reusable Table Columns: Generate reusable table columns organized into a trait.
• Centralized Customization: Changes to the traits automatically propagate across all resources, relation managers, Table widgets, etc.
• Seamless Integration: Works effortlessly with Filament's workflow.

Installation

You can install the package via composer:

Usage

Step 1: Generate Helpers

To generate helpers for a model, use the following Artisan command:

Under the hood, this command leverages Filament's built-in feature for automatically generating forms and tables. You can learn more about this feature in the Filament documentation.

This will create the following structure in your app/Filament/Helpers directory:

Step 2: Use the Helpers

In your Filament resources, relation managers, Table widgets, or any other context, you can reuse the generated helpers.

Example: Using Helpers in a Resource

How It Works

The package organizes the generated code into a helper class and two traits:

1. Helper Class: Combines and exposes reusable methods for form fields and table columns.
2. Traits: Separately define reusable form fields and table columns.

Generated Helper Example

For the User model:

Benefits

1. Single Source of Truth Define your form fields and table columns once. Use them across:

• Resources

• Relation Managers

• Table widgets
• Select Forms (createOptionForm)

2. Ease of Maintenance

• Make a change in the generated traits, and it’s reflected everywhere the helper is used.

3. Consistency

• Ensure consistent form and table structures throughout your project.

Practical Example: Reusing a Form Across Contexts

Imagine you have a form in your UserResource, and you want to reuse it in:

1. A relation manager (e.g., assigning roles to users).
2. A widget (e.g., creating a quick form for new users).

Instead of copying the same schema to multiple places:

You can simply call:

Now, if you need to update the form (e.g., add a date_of_birth field), you update it in one place—the UserFormFields trait.

Conclusion

This package is not just a tool—it’s a best practice for managing reusable forms and tables in Filament projects. By centralizing your form and table logic, you save time, reduce redundancy, and ensure consistency.
