Question

I’m using Play Framework 2.0 (Java), but after implementing a simple InitialData in Globals, I’m having some problem.
I’m using

I have 2 models:

• User(email as ID)
• SomeModel(Long id as ID)

And SomeModel has a field like:

@ManyToOne
  public User user;

So in the and there is a User has many SomeModels connected to it.

In my InitialData I was adding a user to test somethings: [e-mail].

So if I try to add a SomeModel to this test user, I have no problem, even if I try to add more then one.

When I added the SomeModel(lets call a TestModel) in the InitialData I thought that there was no problem, since everything was running in this TestModel. But just now, I saw that if I try to add a new SomeModel to the test user, I get this problem:

[PersistenceException: ERROR executing DML bindLog[] error[Unique index or primary key violation: "PRIMARY_KEY_D ON PUBLIC.SOME_MODEL(ID)"; SQL statement:\n insert into some_model (id, name, description, user_email) values (?,?,?,?) [23505-158]]]

This is my InitialData file:

# Users

users:

    - !!models.User
        email:      [e-mail]
        name:       Test test
        password:   test


# SomeModels
somemodels:

    - !!models.FuzzySystem
        id:       1
        name:       test
        description:   test
        user:       !!models.User
                            email: [e-mail]

I’m lost in this =(

Answer 1

So, I’ve just found out that the initialData shouldn’t have the ID of SomeModel…

After removing the ID field everything worked just fine.

This is how my initialData file is:

# Users

users:

    - !!models.User
        email:      [e-mail]
        name:       Test test
        password:   test


# SomeModels
somemodels:

    - !!models.FuzzySystem
        name:       test
        description:   test
        user:       !!models.User
                            email: [e-mail]
