错误在于,在创建控制器代码时,关联模型的变量留空,而模型的名称留空。为我的所有表创建控制器时会发生错误,但这是其中一个的完整示例。我已经在全新安装的 cakephp 3.2 上复制了这个问题。

这是生成的 2 行错误代码,我在下面包含了完整的详细信息:

$ = $this->Customers->->find('list', ['limit' => 200]);
    $this->set(compact('customer', ''));

我在 config/app.php 中的数据库配置:

'default' => [
     'className' => 'Cake\Database\Connection',
     'driver' => 'Cake\Database\Driver\Sqlite',
     'persistent' => false,
     'host' => 'localhost',
     //'port' => 'non_standard_port_number',
     'username' => null,
     'password' => null,
     'database' => 'tgr.db',
     'encoding' => 'utf8',
     'timezone' => 'UTC',
     'flags' => [],
     'cacheMetadata' => true,
     'log' => false,
     'quoteIdentifiers' => false,
     'url' => env('DATABASE_URL', null),
]

为 add() 方法创建的代码包含错误创建的代码。

public function add(){
    $customer = $this->Customers->newEntity();
    if ($this->request->is('post')) {
        $customer = $this->Customers->patchEntity($customer, $this->request->data);
        if ($this->Customers->save($customer)) {
            $this->Flash->success(__('The customer has been saved.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('The customer could not be saved. Please, try again.'));
        }
    }
    $ = $this->Customers->->find('list', ['limit' => 200]);
    $this->set(compact('customer', ''));
    $this->set('_serialize', ['customer']);
}

我的数据库存储在应用程序根目录中,应用程序找到它并根据我的判断正确连接。数据库架构:

-- Text encoding used: UTF-8
--
PRAGMA foreign_keys = off;
BEGIN TRANSACTION;

-- Table: customers
CREATE TABLE customers (_id INTEGER PRIMARY KEY,district_key INTEGER NOT NULL, name TEXT UNIQUE NOT NULL, short_name TEXT UNIQUE NOT NULL, job_count INTEGER, report_count INTEGER,  FOREIGN KEY (district_key) REFERENCES districts (_id)  );

COMMIT TRANSACTION;
PRAGMA foreign_keys = on;

我找到了答案。我的数据库 id 列是 _id (来自 android 默认 id 列),cakephp bakery 将其解释为具有空名称意义的相关模型,它采用 _id 之前的任何内容并为其创建模型。我已经更新了所有数据库表以反映这一点,并且它工作正常。
