Cakephp 3.x Ajax删除数据时会出现以下错误：“未知方法”；是新的吗；

我尝试在CakePHP3.0.6中使用Ajax删除一条记录

以下是我视图中的jquery（start.ctp）

模型/表格（TeamFreeTable.php）

这是回报

{
"message": "Unknown method \u0022isNew\u0022",
"url": "\/ID\/admins\/delavailable.json",
"code": 500

}

哪里会失败？

您正在将查询对象传递给，但它不是这样工作的，该方法需要一个实体，您必须事先获取该实体

简化示例

$this->delete($this->get($id));

另见

多亏了食谱和一些尝试和错误，这就是我如何通过Ajax删除行的方法

    public function delavailable()
{

    $this->loadModel('TeamFree');

    $teamfree = $this->TeamFree->newEntity(); //create a temporary entity

    if($this->request->is('ajax')) {
        $teamfree = $this->TeamFree->patchEntity($teamfree,$this->request->data); // put the request data into the temp entity
        $this->TeamFree->delete($this->TeamFree->get($teamfree->ID)); //use get() to place the entity property into the delete function and let the delete function refer to the entity
    }
}

你有什么问题？你的代码在哪里失败？它不工作并返回此错误：错误：未知方法“isNew”谢谢你的帮助，我确实让我走上了正确的轨道。请随意使用下面的优化我的工作示例

{
"message": "Unknown method \u0022isNew\u0022",
"url": "\/ID\/admins\/delavailable.json",
"code": 500

$this->delete($this->get($id));

    public function delavailable()
{

    $this->loadModel('TeamFree');

    $teamfree = $this->TeamFree->newEntity(); //create a temporary entity

    if($this->request->is('ajax')) {
        $teamfree = $this->TeamFree->patchEntity($teamfree,$this->request->data); // put the request data into the temp entity
        $this->TeamFree->delete($this->TeamFree->get($teamfree->ID)); //use get() to place the entity property into the delete function and let the delete function refer to the entity
    }
}
