Question

是否可以在网址中使用其他字段？我想使用该名称，但我首先应用toLowerCase（），我正在特定对象中执行。这是我的代码。一切正常，但对象数据没有出现在视图中...任何想法？提前谢谢！

你可以做的是挂钩serialize的{{1}}钩子并在那里提供slu ..

示例：

CategoryRoute

这样您就可以删除模型中的slug computed属性，然后在链接中删除：

App.CategoryRoute = Ember.Route.extend({
  setupController: function(controller, category) {
    controller.set('model', category);
  },
  serialize: function(model) {
    return {
        category_slug: model.get("name").toLowerCase()
    };
  }
});

希望它有所帮助。
