hasOne/hasMany - where is the reference injected?

[Sorin Carbunaru]

I have a unidirectional one-to-many relationship between Game and Highscore, and I want Highscore to contain a reference to a Game.

How do I do this?

Game

this.hasMany(Highscores);

OR

Highscore

this.hasOne(Game);

Again, I want Highscore to have the reference.

I believe you want highscore belongsTo game.

I've read belongsTo is just the inverse of hasOne/hasMany, and it is not even required.

I have a comment belongsTo story in my app and can confirm that story_id is in the comment table.

I’m not sure what behavior is going to be if you don’t specify belongsTo. I would expect eager loading something like comment.story to fail if belongsTo wasn’t specified.

Ben is right. hasMany and belongsTo can use the same foreign key, but until we implement the 'inverse' feature, they don't know anything about each other.

Ok. So having (highscore belongsTo game) and (highscore belongsTo player) will make highscore to have references to both game and player, right? 

[Matthew Eernisse]

Yes, that will create a game_id and player_id on highscore. Are you doing a World Cup API? :)

:)). No, not a World Cup API. I'm working on my Master's thesis and I'm generating some Geddy code from a diagram. It's about model-driven engineering.

[Matthew Eernisse]

Ah, I see. :) Sounds awesome. Let us know if there's anything else we can do to help.
