ORM | Object-Relational Mapping for PHP | Object-Relational Mapping library

You can achieve this using annotate() :

I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.

My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touchs a semaphore file. If the file exists already, it skips the seeds.

I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.

jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:

• https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-database/codegen-database-forced-types/
• https://www.jooq.org/doc/latest/manual/code-generation/codegen-embeddable-types/

Note that the JPADatabase offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.

Use psql to issue your statements to the database via the pipe.

You were close to solving it. The short answer is: just add this line to your hibernate.cfg.xml config file (add empty catalog):

You can filter the queryset with:

I think you might be causing yourself angst because of how you are handling the relationships.

Considering StateWithFacilities

You appear to be saying get the school who's id is equal to the schoolId column in the state.

While the realtionship should be from a column in the School that stores the appropriate StateId.

You appear to be using the reverse.

Example

Perhaps consider this example based upon what you appear to be wanting to do: (States, Schools and Locations have been given a name column to make the output easier to understand)-

State class (Entity and therefore Table) which is top of the hierarchy.

I have had the same issue. This is what I did:

1. I deleted the migrations folder as well as the dist folder
2. I ran npx mikro-orm migration:create --initial

After that, I restarted yarn watch and yarn dev and it worked for me.

Notice the --initial flag. I would recommend to check the official documentation. The migrations table is used to keep track of already executed migrations. When you only run npx mikro-orm migration:create, the table will not be created and therefore MikroORM is unable to check if the migration for the Post entity has already been performed (which includes creating the respective table on the database).

Ben does not use the --initial flag in his tutorial, he might have already ran it prior to the tutorial.
