php - Laravel 表单请求和验证

Question

下面是我在 Controller (Laravel 5) 上对创建/存储和编辑/更新方法使用单一表单验证请求的解决方案。

这是一个麻烦且丑陋的 hack(即它读取 URI 段以获取正在编辑的记录的 ID)。有没有更好的方法来确定请求是否从编辑/更新请求中接收信息？ (不直接将 $id 和标志传递给请求)

/**
 * Sets the basic validation rules that apply to the request.
 *
 * @return array
 */
protected $rules = [    
        'trading_name' => 'required|min:3|max:50|unique:companies',
        'legal_name' => 'required|min:3|max:50|unique:companies',
        'legal_identifier' => 'required|min:3|max:50|unique:companies',
        'status' => 'required',
        'website' => 'active_url',
        'type' => 'required',
        'payment_terms' => 'required|integer|min:0|max:180',
        'credit_limit' => 'required|integer|min:0|max:500000',
        'notes' => 'max:2000',
];

/**
 * Sets addition validation rules depending on the request type (i.e. edit & update).
 * 
 * 
 * @return array
 */
public function rules()
{
    $rules = $this->rules;
    if ($this->is('companies/*') == true) #Add a ignore self-unique rule as this is a edit&update request
    {
        $id = $this->segment(2);
        $rules['trading_name'] = $rules['trading_name'].',trading_name,'.$id;
        $rules['legal_name'] = $rules['legal_name'].',legal_name,'.$id;
        $rules['legal_identifier'] = $rules['legal_identifier'].',legal_identifier,'.$id;
    }
    return $rules;
}

如果您遵循正确的 restful 路由技术 - 您可以改用请求类型 - 为任何验证提供通用解决方案

public function rules()
{
    if($request()->isMethod('put'))
    {
         // Update rules here
    }

    return $this->rules;
}
