在cakephp中更新多个表
我想知道这个函数有什么问题,我只需要更新表中的一个字段或多关联表中的所有字段。 多重更新可以很好地工作,但是当我只更新第一列时,它就不能很好地工作在cakephp中更新多个表,php,mysql,cakephp,cakephp-3.0,Php,Mysql,Cakephp,Cakephp 3.0,我想知道这个函数有什么问题,我只需要更新表中的一个字段或多关联表中的所有字段。 多重更新可以很好地工作,但是当我只更新第一列时,它就不能很好地工作 public function edit($id) { $contractor = $this->Contractors->get($id); $associated = ['ContractorsAttachments' ]; // Used to get the all attachments associ

可以使用获取关联的模型数据 使用 调整后,您的代码将如下所示
$contractor = $this->Contractors->get($id, ['contain'=>'ContractorsAttachments']);
if ($this->request->is(['patch', 'post', 'put'])) {
$contractor = $this->Contractors->patchEntity($contractor, $this->request->data );
if ($this->Contractors->save($contractor,['associated' => ['ContractorsAttachments']])) {
$this->Flash->success(__('The Contractors has been saved.'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('The Contractors could not be saved. Please, try again.'));
}
$this->hasMany('ContractorsAttachments', [
'foreignKey' => 'contractor_id'
]);
还要验证您的承包商模型是否定义了如下关联
$contractor = $this->Contractors->get($id, ['contain'=>'ContractorsAttachments']);
if ($this->request->is(['patch', 'post', 'put'])) {
$contractor = $this->Contractors->patchEntity($contractor, $this->request->data );
if ($this->Contractors->save($contractor,['associated' => ['ContractorsAttachments']])) {
$this->Flash->success(__('The Contractors has been saved.'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('The Contractors could not be saved. Please, try again.'));
}
$this->hasMany('ContractorsAttachments', [
'foreignKey' => 'contractor_id'
]);

希望这会有所帮助:)什么是使用
$associated=['ContractorsAttachments']
什么是使用$associated=['ContractorsAttachments']
