保存与余烬数据的parent_id关系 [英] Saving parent_id relationship with ember data

问题描述

好。我有一个真正的好看的谷歌和其他来源谷歌返回，但我还没有找到一个答案我的问题。

Okay. I've had a real good look through SO and other sources returned by Google, but am yet to find an answer to my problem.

我有两个模型： p>

I have two models:

App.Kid = Ember.Model.extend
    title: DS.attr "string"
    parent: DS.belongsTo "App.Parent"

App.Parent = Ember.Model.extend
    title: DS.attr "string"
    kids: DS.hasMany "App.Kid"

这里讨论的大多数问题都是讨论从侧面加载的JSON数据中检索垃圾数据关系，我有能力做。我需要知道的是如何在创建一个新的孩子时保存parent_id？

Most questions on here discuss retrieving ember data relationships from sideloaded JSON data, which I'm capable of doing. What I need to know is how do I save the parent_id when creating a new kid?

目前我正在App.KidController中保存一个新的孩子：

At the moment I'm saving a new kid in the App.KidController like so:

App.ParentController = Ember.ObjectController.extend
    needs: [ "widgets" ]

App.KidCreateController = Ember.ObjectController.extend
    needs: [ "dashboard" ]

    saveChild: ->
        @content.get( "store" ).commit()

当保存时没有parent_id被看到，但是我得到一个新的父对象（分配给父键），ID为0。

And when saving there is no parent_id to be seen, however I do get a new parent object (assigned to a parent key) with the id of 0.

任何人都可以解释我是在这里做错？

Can anybody explain what I'm doing wrong here?

所以使用我的实际情况我'将解释我在做什么。

So using my actual situation I'll explain what I'm doing.

用户有几个仪表板，其中附有多个小部件。我的模型结构如下所示：

A user has several dashboards which have multiple widgets attached to it. My model structure looks like this:

App.Dashboard = DS.Model.extend
    title: DS.attr "string"
    widgets: DS.hasMany "App.Widget"

App.Widget = DS.Model.extend
    title: DS.attr "string"
    type:  DS.attr "string"
    ...
    dashboard: DS.belongsTo "App.Dashboard"

推荐答案

嗯，原来我是个白痴。我使用Laravel作为我的后端，当定义你的模型时，你需要定义哪些属性是可填充的，但我忘了添加dashboard_id到列表中。一切都正常。

Well, it turns out I was being a idiot. I'm using Laravel as my backend and when defining your models you need to define which attributes are fillable, however I forgot to add dashboard_id to the list. Everything works fine now.
