Question

我正在使用propel als ORM和Sqlite als本地数据库。配置似乎有效（可以创建简单的项目，例如新用户）。但我插入相关项目时遇到麻烦（例如：无法创建与新用户相关的新订单）：

$user = new User();
$user->setFirstName('Chris');
$user->setLastName('somename');
$user->setEmail('example@test.com');
$user->setPassword(password_hash("1234", PASSWORD_DEFAULT));
$user->save(); //works fine

$order = new Order();
$order->setUser($user);
$order->save(); //throws PDOException

我总是得到以下异常：

/usr/bin/php -S localhost:8080 -t /Users/chris/Documents/slim
exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1 near "order": syntax error' in /Users/chris/Documents/slim/vendor/propel/propel/src/Propel/Runtime/Connection/PdoConnection.php:143

我的数据库schema.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<database name="shop" defaultIdMethod="native">

        </foreign-key>
    </table>

        </foreign-key>

</database>

我已经删除了datetime列，所以这不是错误，但可能是某种外键问题。

修改

我试图找到错误并调试我生成的Base/Order.php。 PDO准备语句$con->prepare($sql);将以下字符串抛出异常：

INSERT INTO order（id，user_id）VALUES（：p0，：p1）

异常包含消息near "order": syntax error"，如果我尝试在sqlite控制台中运行一个非常相似的语句，我得到：

SQL＆GT; INSERT INTO order（id，user_id）VALUES（0,1） [2015-02-01 11:45:39] [1] [SQLITE_ERROR] SQL错误或缺少数据库（接近“订单”：语法错误）

我不知道如何“选择”正确的数据库或者为什么这个查询无效，因为它可以插入到用户表中并且两者都在同一个数据库中，...

propel和sqlite无法插入相关项目
