php - 在 yaml 中添加新表时 CRUDlex 不起作用

Question

我尝试使用 symfony 组件找到一种更快的方式来为现有数据库、CRUD、 Composer 方式生成 UI。

找到 CRUDlex .使用 Composer 进行安装，同时设置 CRUDlex sample它工作正常，直到我在示例 crud.yml 中添加新表定义

category:
  label: Category
  table: category
  fields:
    name:
      type: text
      label: Name
      required: true
      unique: true  

yml里加了什么表，访问http://localhost/crudlex/web/category总是报类似这样的错误

InvalidFieldNameException in AbstractMySQLDriver.php line 71: An exception occurred while executing 'SELECT COUNT(id) FROM `category` `category` WHERE deleted_at IS NULL':
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'deleted_at' in 'where clause'

完整的错误信息请查看下面的截图

crudlex 总是询问“id”和“deleted_at”

代码与 CRUDled 示例相同 index.php

    $loader = require __DIR__.'/../vendor/autoload.php';

    //$loader->add('CRUDlex', __DIR__.'/../../CRUDlex/src');
    $app = new Silex\Application();

    $app['debug'] = true;

    $app->register(new Silex\Provider\DoctrineServiceProvider(), array(
        'dbs.options' => array(
            'default' => array(
                'host'      => '127.0.0.1',
                'dbname'    => 'dbname',
                'user'      => 'root',
                'password'  => '',
                'charset'   => 'utf8',
            )
        ),
    ));
    $app->register(new Silex\Provider\SessionServiceProvider());

    $dataFactory = new CRUDlex\MySQLDataFactory($app['db']);
    $app->register(new CRUDlex\ServiceProvider(), array(
        'crud.file' => __DIR__ . '/../crud.yml',
        'crud.datafactory' => $dataFactory
    ));
    $app->register(new Silex\Provider\TwigServiceProvider());

    //$app['crud.layout'] = 'layout.twig';
    $app->mount('/', new CRUDlex\ControllerProvider());

    $app->match('/', function() use ($app) {
        return $app->redirect($app['url_generator']->generate('crudList', array('entity' => 'library')));
    })->bind('homepage');

    $app->run();

和文件夹结构

vendor
web
    > .htaccess
    > index.php
composer.json
crud.yml  

注意:我对 silex 和 symfony2 组件完全陌生 ^_^谢谢，任何建议都非常感谢

您(至少)缺少一个必需的元字段:

• created_at (datetime, not null): 记录创建时间
• updated_at(datetime, not null): 最后一次编辑记录的时间
• version (int, not null): 记录的版本，随着每次编辑而递增
• deleted_at (datetime):如果不为空:记录被(软)删除的时间

在您的案例中，完整的表创建 SQL 如下所示:

CREATE TABLE `category` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `created_at` datetime NOT NULL,
  `updated_at` datetime NOT NULL,
  `deleted_at` datetime DEFAULT NULL,
  `version` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `name` (`name`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
