版本号：4.2.9
我的编辑视图正在用数据填充我的输入，但是当我更改它们并单击“保存”时，它没有保存，而是给我一条“用户已保存”消息。
用户控制器. php编辑函数

public function edit($id = null)
    {
        $user = $this->Users->get($id, [
            'contain' => ['Userdata'],
        ]);
        if ($this->request->is(['post', 'put'])) {
          $user = $this->Users->get($id, [
              'contain' => ['Userdata'],
          ]);
            if ($this->Users->save($user)) {
                $this->Flash->success(__('The user has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The user could not be saved. Please, try again.'));
        }
        $this->set(compact('user'));
    }

我的编辑. php

<div class="users form large-9 medium-8 columns content">
    <?php echo $this->Form->create($user) ?>
    <fieldset>
        <legend><?= __('Edit User') ?></legend>
        <?php
            echo $this->Form->control('userdata.Email');
            echo $this->Form->control('userdata.UserName');
            echo $this->Form->control('PasswordHashed', ['type' => 'password']);
        ?>
    </fieldset>
    <?= $this->Form->button(__('save')) ?>
    <?= $this->Form->end() ?>
</div>
