Hi Benjamin,

  It is not clear to me which of the following you are attempting.

1. To create a OneToMany (and its corresponding ManyToOne) relationship
between two entities.
2. To automatically create tables from entities and have the database
foreign key constraint automatically generated.

Please provide a little more detail about what you are trying to do and
the code that you are using to set up your ManyToOne.
