cakephp：更新相关的belogsTo表

我正在更新属于地址模型的零售商模型，当我创建新记录时，它可以轻松地为地址创建新行，并在零售商模型上插入其密钥：

视图：

型号（零售商）：

零售商控制器->添加（）

但是，当我尝试更新零售商时，零售商模型已更新，但没有更新以前的地址记录，而是创建了新记录，并将其密钥放在零售商表上：

RetailersController->edit($id = null)
$this->Retailer->id = $id;
$this->Retailer->saveAll($this->request->data);

我也试过这个，但不起作用：

RetailersController->edit($id = null)
$post = $this->Retailer->findById($id);
$this->Retailer->id = $id;
$this->request->data['Retailer']['address_id'] = $post['Retailer']['address_id'];
$this->Retailer->saveAll($this->request->data);

---

你可能只需要告诉它地址的id

echo $this->Form->input('Address.id');

---

否则它将执行创建，正如您所说。

谢谢，它对我有效，尽管我将地址id的值放在控制器中而不是视图中：-

$this->request->data['Address']['id']=$post['Retailer']['Address\u id']

RetailersController->edit($id = null)
$this->Retailer->id = $id;
$this->Retailer->saveAll($this->request->data);

RetailersController->edit($id = null)
$post = $this->Retailer->findById($id);
$this->Retailer->id = $id;
$this->request->data['Retailer']['address_id'] = $post['Retailer']['address_id'];
$this->Retailer->saveAll($this->request->data);

echo $this->Form->input('Address.id');
