plone - contentmirror 与 plon 4 集成

Question

我正在尝试让 contentmirror 产品与 plone4 网站一起使用。我从头开始创建了一个构建，并且仅包含此链接所示的内容镜像包: http://code.google.com/p/contentmirror/wiki/Installation

我已根据文档中包含的说明在 mysql 数据库中设置了表。

当我创建 Plone 站点时，出现以下错误:

因此网站无法创建。我尝试删除该表，但弹出另一个错误，表明它找不到表，所以我认为我的方向是正确的。

我正在尝试看看这是否是一种将内容存储到 SQL 数据库的可行方法，如某些页面所示。我肯定在这里遗漏了一些东西。有人有使用该产品的经验来帮助我吗？

谢谢。 金英勇

Answer 1

免责声明:我没有使用 ContentMirror 的经验，所以我可能完全偏离目标，但从您发布的内容来看，表“内容”的“id”值似乎没有自动递增。

在 SQLAlchemy 中，这是由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”的相应数据库架构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,
   ...
)
