When to use this skill

Use this skill when you need to create or edit a single Eloquent model record using a Livewire component. This is ideal for standard CRUD operations where complex relationship editing is not required in the same view.

Features

•Boilerplate Reduction: Extends AutoForm to handle all form mapping and state management.
•Rules-Driven: Validation rules drive both the data loading and the persistence logic.
•Automatic Error Scoping: Validation errors are automatically prefixed with form. for easy display.
•Model Refreshing: Use reloadModel(Model $model) to synchronize the form buffer with a fresh model state.

Implementation Example

Livewire Component

Extend the AutoForm base class and use setModel() to initialize the buffer.

php

use SchenkeIo\LivewireAutoForm\AutoForm;
use App\Models\User;

class UserForm extends AutoForm
{
    public function mount(User $user)
    {
        // Mandatory: Initialize the form buffer with the model
        $this->setModel($user);
    }

    public function rules(): array
    {
        return [
            'name' => 'required|string|max:255',
            'email' => 'required|email|unique:users,email,' . $this->form->rootModelId,
        ];
    }
}

Blade View

Always bind your inputs to the form property using wire:model.

html

<form wire:submit.prevent="save">
    <div>
        <label>Name</label>
        <input type="text" wire:model.blur="form.name">
        @error('form.name') <span>{{ $message }}</span> @enderror
    </div>

    <div>
        <label>Email</label>
        <input type="email" wire:model.blur="form.email">
        @error('form.email') <span>{{ $message }}</span> @enderror
    </div>

    <button type="submit">Save</button>
</form>
