Ember-Data: How to use `DS.Adapter.findHasMany`

Question

UPDATE

Note that this question applies to Ember Data pre-1.0 beta, the mechanism for loading relationships via URL has changed significantly post-1.0 beta!

Answer 1

I was glad to find this post, helped me. Here is my version, based off the current ember-data and your code.

findHasMany: function(store, record, relationship, details) {
    var adapter = this;
    var serializer = this.get('serializer');
    var type = relationship.type;
    var root = this.rootForType(type);
    var url = (typeof(details) == 'string' || details instanceof String) ? details : this.buildURL(root);
    return this.ajax(url, "GET", {}).then(function(json) {
            adapter.didFindMany(store, type, json);
            var list = $.map(json[relationship.key], function(o){ return serializer.extractId(type, o);});
            store.loadHasMany(record, relationship.key, list);
        }).then(null, $.rejectionHandler);
},

for the reload issue, I did this, based on code I found in another spot, inside the serializer I overrode:

materializeHasMany: function(name, record, hash, relationship) {
    var type = record.constructor,
            key = this._keyForHasMany(type, relationship.key),
            cache = record.cacheFor('data');
    if(cache) {
        var hasMany = cache.hasMany[relationship.key];
        if (typeof(hasMany) == 'object' || hasMany instanceof Object) {
            record.materializeHasMany(name, hasMany);
            return;
        }
    }
    var value = this.extractHasMany(type, hash, key);
    record.materializeHasMany(name, value);
}

I'm still working on figuring out paging, since some of the collections I'm working with need it.
