contentmirror与plone集成4

时间：2011-04-19 19:49:21

标签： plone zope

我正在尝试让contentmirror产品与plone4站点一起使用。我已经从头开始创建了一个buildout，并且只包含了这个链接指示的contentmirror包： http://code.google.com/p/contentmirror/wiki/Installation

我已根据文档中包含的说明在mysql数据库中设置表。

当我创建我的plone网站时，我收到以下错误：

因此无法创建网站。我试过放下桌子，但是弹出另一个错误，表示找不到桌子，所以我觉得我的方向正确。

我正在尝试查看这是否是一种将内容存储到sql数据库的可行方法，正如一些页面所指出的那样。我在这里肯定遗漏了一些东西。有没有人有使用这个产品来帮助我的经验？

感谢。 年轻的金

1 个答案:

答案 0 :(得分：3)

免责声明：我没有使用ContentMirror的经验，因此我可能完全脱离目标，但从您发布的内容来看，“id”值似乎没有针对表'内容'自动增加。

在SQLAlchemy中，这是由一个覆盖默认行为的错误设置引起的，例如

Table('content', metadata,
  Column('id', Integer, primary_key=True, autoincrement=False),
  ...
)

在使用'ddl.py'脚本生成的SQL文件（'mirror.sql'）中，检查表'content'的相应数据库模式定义是否将列的属性'AUTO_INCREMENT'设置为'TRUE' 'id'，如下例所示：

CREATE TABLE `content` (
   `id` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
   ...
)
