@danielsous the current implementation is not handling multiples IDs:

const Project =
    entity('Project', {
        id1: id(String),
        id2: id(String),
        name: field(String),
    })

@danielsous great contrib! having support for entities relationship is one of the most important feature for now.

just a few points:

[dalssoft]

I don't think it is necessary to explicitly inform PKs (ids: [) on the repository since it is able to detect ids using metadata.

[dalssoft]

1 to 1 scenario:

Testing with two entities with relationship between then:

const User =
        entity('User', {
          id: id(String),
          nickname: field(String),
        })

const Project =
        entity('Project', {
          id: id(String),
          user: field(User),
        })

The repository (ProjectRepository) was created with foreignKeys: [{ user_id: String ,}] which is correct, but the migration (20220904220920_projects.js) had table.undefined('user') as the field definition, which is a bug.

[dalssoft]

1 to Many scenario:

Testing with two entities with relationship between then:

const User =
        entity('User', {
          id: id(String),
          nickname: field(String),
        })

const Project =
        entity('Project', {
          id: id(String),
          user: field([User]),     // <----- Many users
        })

When herbs update it throws a expection:

@danielsous I think your PR is very close to the effort started by this PR https://github.com/herbsjs/herbs-cli/pull/144 created by @endersoncosta regarding issue https://github.com/herbsjs/herbs-cli/issues/145 . You guys should join forces to finish it. As I said, this feature is veeery import for the project
