ember.js - 从任何路由交换嵌套资源

Question

我有带嵌套动态段的路由,例如/:locale/products/:product_id/items/:item_id等嵌套.我想在区域设置路由中的操作中替换区域设置.我/:locale更改语言环境时,我不想转换到基本路由.

区域路线行动:

actions: {
  localeChanged: function(locale) {
    var route = this.controllerFor('application').get('currentRouteName');
    this.transitionTo(route, locale);
  }
}

这只适用于我没有深度嵌套的情况.我想避免localeChanged在每条路线中实施动作,以提供给定路线所需的确切模型.

更新1 - 脏解决方案:

actions: {
  localeChanged: function(locale) {
    var routes = this.router.router.currentHandlerInfos;
    var models = [];
    for (var i = 0; i < routes.length; i++) {
      var params = routes[i].params;
      for (var param in params) {
        if (params.hasOwnProperty(param)) {
          models.push(param === 'locale' ? locale : params[param]);
        }
      }
    }

    var args = models.slice();
    var currentRouteName = this.controllerFor('application').get('currentRouteName');
    args.unshift(currentRouteName);
    this.transitionTo.apply(this, args);
  }
}

我说脏,因为迭代this.router.router.currentHandlerInfos似乎容易出错.有没有更好的办法？

您可以创建一个添加此操作的基本路由。然后你的所有路由都可以继承这个基本路由。您只需编写一次代码，它就可以在所有路由中共享。例如。

App.BaseRoute = Ember.Route.extend({
   actions: {
    localeChanged: function(locale) {
     var routes = this.router.router.currentHandlerInfos;
     var models = [];
     for (var i = 0; i < routes.length; i++) {
      var params = routes[i].params;
      for (var param in params) {
        if (params.hasOwnProperty(param)) {
          models.push(param === 'locale' ? locale : params[param]);
        }
      }
     }  
     var args = models.slice();
     var currentRouteName =  this.controllerFor('application').get('currentRouteName');
     args.unshift(currentRouteName);
     this.transitionTo.apply(this, args);
    }
   }});


App.SomeRoute = BaseRoute.extend();
