Step 5: Generate Request Validation

创建表单验证类。

File Location

modules/{Module}/Http/Requests/{Model}Request.php

Template

<?php

namespace Modules\{Module}\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class {Model}Request extends FormRequest
{
    public function authorize(): bool
    {
        return true;
    }

    public function rules(): array
    {
        return [
            // Generated from field definitions
        ];
    }

    public function messages(): array
    {
        return [
            // Custom messages
        ];
    }
}

Validation Rules Mapping

Field Type	Validation Rule
string(n), required	'required|string|max:n'
string(n), nullable	'nullable|string|max:n'
integer	'sometimes|integer|min:0'
decimal	'required|numeric|min:0'
tinyint (status)	'sometimes|integer|in:1,2'
foreign_key	'required|integer|exists:table,id'
text	'nullable|string'
email	'required|email|max:100'
date	'nullable|date'

Unique Validation

对于更新操作，需要排除当前记录：

public function rules(): array
{
    $id = $this->route('id');
    
    return [
        'email' => "required|email|unique:{table},email,{$id}",
    ];
}
