custom ember data's restful URL and modify the HTTP method

application.js

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
    // namespace: 'api/v2',
    host: 'http://localhost:8080',

    find: function(store, type, id, snapshot) {
        return this.ajax(this.buildURL(type.typeKey, id, snapshot, 'find'), 'GET');
    },


    findAll: function(store, type, sinceToken) {
        var query, url;

        if (sinceToken) {
            query = {
                since: sinceToken
            };
        }

        url = this.buildURL(type.typeKey, null, null, 'findAll');

        return this.ajax(url + "/list", 'GET', {
            data: query
        });
    },

    createRecord: function(store, type, snapshot) {
        var data = {};
        var serializer = store.serializerFor(type.typeKey);
        var url = this.buildURL(type.typeKey, null, snapshot, 'createRecord');

        serializer.serializeIntoHash(data, type, snapshot, {
            includeId: true
        });

        return this.ajax(url + "/add", "POST", {
            data: data
        });
    },

    updateRecord: function(store, type, snapshot) {
        var data = {};
        var serializer = store.serializerFor(type.typeKey);

        serializer.serializeIntoHash(data, type, snapshot);

        var id = snapshot.id;
        var url = this.buildURL(type.typeKey, '', snapshot, 'updateRecord');

        return this.ajax(url + "/update/"+id, "POST", {
            data: data
        });
    },

    deleteRecord: function(store, type, snapshot) {
        var id = snapshot.id;

        return this.ajax(this.buildURL(type.typeKey, '', snapshot, 'deleteRecord') + "/delete/"+id, "POST");
    }
});

Thank you, good gist!
Note:
type.typeKey moved to type.modelName
