My attempt at defining a one-to-one relationship using backbone relational.
B is defined without any dependencies or knowledge of A
var B = Backbone.RelationalModel.extend({
/* No relationship defined with A */
});
A is then defined, with an attempt to define a one-to-one relationship to B.
var A = Backbone.RelationalModel.extend({
relations: [
{
type: Backbone.HasOne,
key: 'b',
relatedModel: B,
reverseRelation: {
key: 'a',
type: Backbone.HasOne
}
}]
/* ... */
});
The backbone relational documentation has this to say about one-to-one relationships:
The default reverseRelation.type for a "HasOne" relation is "HasMany". This can be set to "HasOne" instead, to create a one-to-one relation.
Inspecting the results of this indicates that when I do
var someId = 123;
var myB = B.findOrCreate(someId);
var myA = A.findOrCreate(someId);
Both objects myA and myB are created successfully, with all the expected data.
The related object, however is not there. I want myA.b to reference myB, and it appears that backbone relational has created this key but lefty it undefined.
I have not specified that the "join" is meant to happen using the id attributes of both classes - however I cannot figure out how.
How do I accomplish this?
