I seem to remember having discussed how to filter the Meta.all() list to only whats in one of the unit objects (not Meta...), I wonder why a specialized all() extension couldn't be generated for each such unit... it could be useful when using connections to multiple dbs in the same service and I need to create the schema for only one of those units in one connection.

If you want to retrieve only the metamodels associated with a specific Unit, please use the EntityMetamodels.list function.

🤔 There's a shortcut for EntityMetamodels.all() in Meta, maybe there should be one for the units fun FooUnit.all() = EntityMetamodels.list(this) so that it shouldn't confuse users, and also it would be more discoverable...

Also, I'm wondering if this feature works between gradle modules... it seems like not.

[Toshihiro Nakamura]

Users should implement the all function as a regular function, not as an extension function.

object FooUnit {
    fun all(): List<EntityMetamodel<*, *, *>> {
        return EntityMetamodels.list(FooUnit)
    }
}

Ok, that's an idea. I guess this is another point that could be mentioned in the docs if that's the way to do it...

I just hope it works in my other module...
