[Vuejs]-Vuex-ORM insert and merge two api calls related to each other

What you’re seeing in vue-devtools is expected.

Relationships are not inserted into the store, they are inserted into their respective "tables" and assigned foreign keys to create a reference to that relationship.

When you query your entities to include relations i.e. User.query().with('posts').get() you’ll notice that posts will be populated. The relationship fields in the store however will always show as empty array’s (for many relations) or null (for single relations) since this is simply the schema for the entity.
