Relations

[kmashiki]

For the A.hasOne(B, ...) relation, does this mean that A must have exactly one B or that A must have at most one B?

Also,
For example,
Post.hasOne(Geo, "geo", "geo_id", "associated.id").
User.hasOne(Geo, "geo", "geo_id", "associated.id").
School.hasOne(Geo, "geo", "geo_id", "associated.id").
How would you define the other direction of the relation?
We basically want to say something like 'Geo.belongsTo(Post || User || School,' but are not sure of the syntax.
