请注意,Category/new没有路由,因为{{render}}助手不需要它。请参阅:(参见页面底部的表格)关于文章,
类别是一个有很多,因此您将类别NewController的模型设置为一个类别数组(除非您遗漏了一个部分,当用户单击“新建”或其他内容时,它会创建一个类别对象。)看起来它应该会起作用。你能设置一个JSFIDLE吗?我开始在这里乱说…:)这是否意味着我必须在saveCategory
操作中“手动”检索数据?我认为有可能为{{render}}
助手提供一个单独的模型,如指南中所述。请参阅:您应该在{render}}
标记:{{render“category/new”App.category}}
上隐式地将模型作为目标,但我不确定它是否按您希望的方式工作。
