与用户的 OneToMany 关系
OneToMany relationship with User
我刚刚用代码生成器开始了一个项目"Jhipster"。我正在尝试与 "User" 关系建立 OneToMany 关系。我已经看过很多主题，但找不到任何有效的答案。你有什么想法？我什至尝试过一段中间关系，但没有任何效果。
非常感谢。
您可以在模型实体和特殊实体用户之间创建关系。但是你必须考虑到这个实体的限制。正如它出现在 JHipster documentation:
Tip: the User entity
Please note that the User entity, which is handled by JHipster, is
specific. You can do:
many-to-one relationships to this entity (a Car can have a many-to-one relationship to a User). This will generate a specific
query in your new entity repository, so you can filter your entity on
the current security user, which is a common requirement. On the
generated Angular/React client UI you will have a dropdown in Car to
select a User.
many-to-many and one-to-one relationships to the User entity, but the other entity must be the owner of the relationship (a Team can
have a many-to-many relationship to User, but only the team can
add/remove users, and a user cannot add/remove a team). On the
Angular/React client UI, you will also be able to select a User in a
multi-select box.
When using the UAA authentication type, you can only create
relationships to the User entity if the related entity is also within
the UAA microservice.
