Question

我在生成简单的数据库表单模型时遇到了麻烦。我正在使用：

Symfony 1.4.4上的学说
MySQL Workbench 5.2.16 with Doctrine Export 0.4.2dev

所以我的ERL模型是：

Genereted YAML文件：

detect_relations: true

      local: course_id
      foreign: id
      foreignAlias: UserCourses
      foreignType: many
      owningSide: true

无论我尝试什么，此错误发生在：

之后

symfony doctrine:build --all --no-confirmation

SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'user_userid' doesn't exist in table. Failing Query: "ALTER TABLE user_has_course ADD CONSTRAINT user_has_course_user_userid_user_id FOREIGN KEY (user_userid) REFERENCES user(id)". Failing Query: ALTER TABLE user_has_course ADD CONSTRAINT user_has_cou
rse_user_userid_user_id FOREIGN KEY (user_userid) REFERENCES user(id)

目前我正在研究Symfony，并坚持这个错误。请帮忙。

Answer 1

正如错误中所述：“user.user_id”列不存在。在您的关系中，您指的是一个名为“user_id”的列，该列应该位于“user”表中，而是您的用户表中包含“id”列。

Answer 2

确保将InnoDB用作Schema的引擎，因为MyISAM和其他人不支持外键。
