问题：
ORM原则：使用由外键组成的复合主键保持集合
蒋岳
我猜这是一个教义错误（我在JIRA问题跟踪器上提交了一个问题），但万一只是用户错误，我决定在这里发布它。
使用由2个外键和一个元数据字段组成的复合主键在联接表中持久化实体集合在某些情况下会失败。代码是以这里的指令为基础的：条令文件

尝试向表gpa_assessment_value添加一个Id，然后使用命令行生成实体。如果不添加id字段，从数据库映射orm文件将不会创建gpa_assessment_value.orm.yml。
CREATE TABLE gpa_assessment_value
(
id bigserial NOT NULL,
grade_point_average_id bigint NOT NULL,
assessment_id bigint NOT NULL,
point_value numeric(4, 2) NOT NULL,
PRIMARY KEY (id,assessment_id, grade_point_average_id),
FOREIGN KEY (assessment_id) REFERENCES assessment,
FOREIGN KEY (grade_point_average_id) REFERENCES grade_point_average
);
