Ember.js 余烬插入具有多个关系的记录-不工作

我已经在这个问题上纠缠了两天了，一直无法在网上找到解决方案。我希望你们中的一些人能帮忙

我有以下型号：

App.Project = DS.Model.extend({
    name: DS.attr('string'),
    project_teams: DS.hasMany('projectTeam')
});

App.ProjectTeam = DS.Model.extend({
    sde_effort: DS.attr('number'),
    project: DS.belongsTo('project'),
    team: DS.belongsTo('team')
});

App.Team = DS.Model.extend({
    project_teams: DS.hasMany('projectTeam'),
    name: DS.attr('string')
});

以及my projectsController中的以下代码：

var project = store.createRecord('project', {
                name: projectName
            });

            project.save().then(function(projectRecord){
                var teamHookerUpper = function(teamId, sdeEffort, idx){
                    store.find('team', teamId).then(function(team){
                        var project_team = store.createRecord('project_team', {
                            project: projectRecord,
                            sde_effort: sdeEffort,
                            team: team
                        });
                        console.log('project team has been created');
                        project_team.save().then(function(pt){
                            projectTeamIds.push(pt.get('id'));
                            if(idx == sdeHeads.length - 1){
                                console.log(projectRecord);
                                projectRecord.set('project_teams', projectTeamIds);
                                projectRecord.save();
                            }
                        });

                    });
                }

                for(var i = 0; i < sdeHeads.length; i++){
                    teamHookerUpper(teamIds[i], sdeHeads[i], i);
                }
            });

编辑2： 下面是ruby中相应的数据模式

ActiveRecord::Schema.define(version: 20131230144053) do

  create_table "project_teams", force: true do |t|
    t.integer  "sde_effort"
    t.integer  "project_id"
    t.integer  "team_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "project_teams", ["project_id"], name: "index_project_teams_on_project_id"
  add_index "project_teams", ["team_id"], name: "index_project_teams_on_team_id"

  create_table "projects", force: true do |t|
    t.string   "name",           null: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "teams", force: true do |t|
    t.string   "name",       null: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end

end

你能检查一下请求中发送的参数吗？sdeeds来自哪里？sdeeds是我从前端收集的一个值数组。它的长度与数组teamid相同。我基本上迭代了sdeHeads，并使用索引检索teamId和sdeEffort，因为两者的长度相同，并创建了一个新的ProjectTeam对象，该对象需要sdeEffort编号，project和teamI使用发送的请求及其相应的服务器响应更新了我的问题，并在Rubyth中包含DB模式。这可能是相关的：不，im returning@project。您是否认为问题可能是由于表定义引起的。因为您可以看到，对于ProjectTeam，我需要项目id和团队id，而从前端我发送jsonified对象。我不确定那是个错误还是应该是那样的。。

ActiveRecord::Schema.define(version: 20131230144053) do

  create_table "project_teams", force: true do |t|
    t.integer  "sde_effort"
    t.integer  "project_id"
    t.integer  "team_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "project_teams", ["project_id"], name: "index_project_teams_on_project_id"
  add_index "project_teams", ["team_id"], name: "index_project_teams_on_team_id"

  create_table "projects", force: true do |t|
    t.string   "name",           null: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "teams", force: true do |t|
    t.string   "name",       null: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end

end
