random-jpa's Issues

Provide mechanism to cleanup data from the database

Primary table should be loaded if foreign key Id provided

Let us say we have a link, Link.newLink(Pizza_.cheeseId, Cheese_.id), so Pizza has a foreign key to Cheese.

Now if I say jpaContext.createAndPersist(Entity.of(Pizza.class).with(Pizza_.cheeseId, 123)), it should load existing Cheese Entity with id 123. and not try create another Cheese.

improve performance by loading entites only once

I can't generate the JPAContext

Hello, I am using spring boot, when trying to create a jpaContext I get a exception

Code example:

@PersistenceContext
private EntityManager entityManager;

    @Test
    public void createAuthorization(){

        JPAContext jpaContext = JPAContextFactory.newInstance(Database.POSTGRES, entityManager)
                .generate();
   }

Can you help me please

Add Debugging to the creation plan so failures can be tracked down.

As the execution plan is executed, Random JPA should log the entities it is trying to create, before it creates them so that, when a sql exception is thrown, then this debug list will show WHERE in the tree it occured, and the factory context can be corrected.

For instance, this is what a typical failure looks like, if I'm reading this correctly, it ran into a constraint violation on the 9th object that it was attempting to create in the tree. But there is no constraint name or Pojo name, and there are only debug logs on success, no debug logs on a per line item basis:

[Feature Request] Supports other JPA provider than hibernate

I would have been really happy to use your library however I can't as I am using a different JPA provider than you. I could probably use both in parallel but that wouldn't be convenient.

No way to resolve "Cyclic dependency found for class"?

One of my @Entity classes has a reference to itself. It would prefer this to be set to null or a fixed value when generating that entity. I don't really want to edit the entity class itself.

But, I don't see a way to do this. The error comes as soon as I call JpaContextFactory#generate. I tried assigning a custom attribute and class generator for this class, but it still gives me the error.

I also tried ignoreLink. See the following example. With this, it fails at the call to jpaContextFactory.generate() because the link's from and to fields are null. I'm not seeing anything in the code which would look for the @StaticMetamodel annotation and initialize those?

        final com.github.kuros.random.jpa.JPAContextFactory jpaContextFactory =
            com.github.kuros.random.jpa.JPAContextFactory.newInstance(Database.ORACLE, entityManager);
        final Generator generator = Generator.newInstance();
        Link link = Link.newLink(JobTask_.parent, JobTask_.id);
        jpaContextFactory.with(Dependencies.newInstance()
            .ignoreLink(link));
        JPAContext jpaContext = jpaContextFactory.generate();
        jpaContext.remove(JobTask.class);

@StaticMetamodel(JobTask.class) 
class JobTask_ {
    public static volatile SingularAttribute<JobTask, Long> id;
    public static volatile SingularAttribute<JobTask, Job> job;
    public static volatile SingularAttribute<JobTask, Environment> environment;
    public static volatile SingularAttribute<JobTask, JobTask> parent;
}

Here's the relevant part of my @Entity.

@Entity
@Table(name = "JOB_TASKS")
public class JobTask {
    @Id
    @GeneratedValue(generator = "triggerAssigned")
    @Column(name = "JOB_TASK_ID")
    protected Long id;

    @ManyToOne
    @JoinColumn(name = "job_id", updatable = false, nullable = false)
    @NonNull
    private Job job;

    @Column(name = "ENVIRONMENT_ID")
    @Convert(converter = EnvironmentConverter.class)
    @NonNull
    private Environment environment;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "parent_job_task_id")
    private JobTask parent;
}

Random attribute generator is not working for Ids

Specify order when creating entities with no relations

Cache.set is not working with ref id

Cache.set is not working when we want to override reference table column value

Incorrect provider is set when using hibernate-validator

If both eclipselink and hibernate-validator exist on classpath, then com.github.kuros.random.jpa.metamodel.AttributeProviderFactory will choose HibernateProvider because hibernate-validator contains org.hibernate.Version class.
I would suggest to reverse checking logic - check for eclipselink first.

Entity was not getting persisted with detached error if reference column maps to same id

Scenario:

@Entity
@Table(name = "entity")
public class Entity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

    @Column(name = "name")
    private Long id;

    @OneToOne
    @JoinColumn(name = "id")
    private ReferencedEntity refEntity;

  ...
}

In this type of entity, Persistence was failing giving detached/constaint violation error intermittently

Provide mechanism to fetch deletion cache before item to be deleted

I want a mechanism to fetch all the items to be deleted before remove method

Mechanism needed to handle entites created by triggers

If a trigger a inserting new rows into a table, I need a mechanism to load these entities

Create data of entities at the same level

For example I have this tables:

Invoices (Parent)
InvoiceDetails (Child)
InvoiceTrack (Child)

Relations:
1 Invoice -> N InvoiceDetails
1 Invoice -> N InvoiceTrack

I want generate 1 Invoice and 2 InvoiceDetails and 2 InvoiceTrack in the same plan. I understood that it's a tree structure, so I don't know if my intent is posible.

I expected something like this:

└── *ROOT*
    └── (h=1) Invoice|0
        ├── (h=0) InvoiceDetails|0
        ├── (h=0) InvoiceDetails|1
	├── (h=0) InvoiceTrack|2
	├── (h=0) InvoiceTrack|3

My Links:

	links.add(Link.newLink(InvoiceDetails_.id, Invoice_.details));
        links.add(Link.newLink(InvoiceTrack_.id, Invoice_.track));

My Creation Plan:

 final JPAContext jpaContext = JPAContextFactory
                .newInstance(Database.POSTGRES, entityManager)
                .with(dependencies)
                .generate();

final CreationPlan creationPlan = jpaContext.create(
                Entity.of(Invoice.class)
                Entity.of(InvoiceDetails.class, 2),
                Entity.of(InvoiceTrack.class, 2)
        );

Output:

└── *ROOT*
    └── (h=1) Invoice|0
        ├── (h=0) InvoiceDetails|0
        │   ├── (h=0) InvoiceTrack|0
        │   └── (h=0) InvoiceTrack|1
        └── (h=0) InvoiceDetails|1
            ├── (h=0) InvoiceTrack|2
            └── (h=0) InvoiceTrack|3
