Ember.js EmberFire和嵌套数组
我正在尝试我的第一个基于ember的项目,并将emberfire集成到其中以获得Firebase功能。我正在为另一个项目构建一个树菜单生成器 firebase数据库的json如下所示:Ember.js EmberFire和嵌套数组,ember.js,firebase,Ember.js,Firebase,我正在尝试我的第一个基于ember的项目,并将emberfire集成到其中以获得Firebase功能。我正在为另一个项目构建一个树菜单生成器 firebase数据库的json如下所示: { "default" : { "_type" : "arrayObject", "name" : "unnamed", "_name" : "default", "menus" : { "Top" : { "menu" : {

无论如何,我已经成功地使用了一个emberFire分支,它从我的初始数组中提供了一个emberFire对象。()
这很有效
我有一个嵌入的数组,我把它转换成另一个emberFire对象数组
我的代码:
我使用了与原始ObjectArray创建类似的行为,为嵌套在“ssApp”中的“ssMenus”数组创建了第二个,但它似乎没有填充来自Firebase的正确数据,路由器甚至没有使用空数组启动
正确的行为是当你点击一个“应用程序”时,应用程序的名称出现在底部(有效!),菜单的名称出现在旁边(无效)
无论如何,请救命 我明白了
- 我正在手动编写子firebase引用。我通过最初的firebase对象找到了实现方法
- 我没有将子引用封装在firebase对象中,而是尝试将它注入到不属于它的地方
- 我试图创建第二条路线,但我不需要它
