我的模型中有以下验证：
validates :cep, presence: true, :unless => lambda { |o| o.location }
如何自定义验证失败时显示的错误消息？
答案 0 :(得分：1)
将foreach($rows as $k=>$row1) { //add index $k to use an automatic autoincrement for the key
//and put it inside each fields
$response[$k]['id'] = $row1['id'];
$response[$k]['category'][] = $row1['category'];
$response[$k]['text'] = $row1['text'];
$response[$k]['image'] = $row1['image'];
}
选项传递给message方法。
