cakePHP模型内置回调函数afterFind()的使用。

在用find获取数据后，我们要对所获取到的数据做一些处理，这时，直接在模型层覆盖cakephp内置的回调函数，使用find时会自动调用。

其中$baomings 就是find 到的 $this->data

public function afterFind($baomings)
    {
        foreach ($baomings as $key => $val) {
            $baomings[$key]['Baoming']['status_cn'] = "未知";
            if ($val['Baoming']['invalid'] == 1) {
                $baomings[$key]['Baoming']['status_cn'] = "无效";
            } else {
                if ($val['Baoming']['status_trace'] == 0)
                    $baomings[$key]['Baoming']['status_cn'] = "未开始";
                else if ($val['Baoming']['status_trace'] >= 1 && $val['Baoming']['status_trace'] < 6) {
                    $baomings[$key]['Baoming']['status_cn'] = "正在跟踪";
                } else if ($val['Baoming']['status_trace'] == 6) {
                    $baomings[$key]['Baoming']['status_cn'] = "已经签约";
                } else if ($val['Baoming']['status_trace'] == 7 || $val['Baoming']['status'] == 3) {
                    $baomings[$key]['Baoming']['status_cn'] = "已竣工";
                }
            }
        }
        return  $baomings;

    }
