使用cakephp save

Question

我有一个表单，在提交时我将值传递给控制器​​，数组看起来像这样。

    [submit] => Post
    [File] => Array
        (
            [content] => dfgdfgdfg
        )

    [Groups] => Array
        (
            [group_name] => 190
        )

    [News] => Array
        (
            [is_private] => 1
            [user_id] => 285
            [content] => <p>dfgdfgdfg</p>

        )

    [Posts] => Array
        (
            [rating] => 5.2
            [rating_enabled] => on
        )

除评级之外的所有值都正确保存到数据库中。我在前端使用滑块，其值是评级。 在db中，rating字段是十进制类型，Posts [rating]的类型是string，所以我使用floatval将它转换为float。

if(  isset($this->request->data['Posts']['rating_enabled'])  ){
                 $this->request->data['News']['rating'] = floatval($this->request->data['Posts']['rating']);
            }

完成保存后

$this->News->save($this->request->data);

仅保存$ this-＆gt; request-＆gt;数据[＆＃39;新闻＆＃39;] [＆＃39;评级＆＃39;]未保存，但在检查数据数组时，其值为

 [News] => Array
        (
            [is_private] => 1
            [user_id] => 285
            [content] => <p>dfgdfgdfg</p>
            [rating] => 5.2
        )

有人能告诉我错误吗

Answer 1

请检查mysql表评级必须是float
