Question

使用ember数据，我想使用slug找到模型的id。我一直关注the approach found on pixelhandler's ember blog，但这不适用于我的服务器，它不支持blog/post?slug=mypost等查询参数。

我可以为serialize我的博客帖子找到正确的网址，但是Ember在刷新时无法找到正确的model。

我的post.js路线：

  import Ember from "ember";
  import SlugRouteableMixin from "../../mixins/slug-routeable";
  var PostsPostRoute;

  PostsPostRoute = Ember.Route.extend(SlugRouteableMixin, {
    model: function(params) {
      return new Ember.RSVP.Promise((function(_this) {
        return function(resolve, reject) {
          var found;
          found = _this.store.filter("post", function(post) {
            console.log("Comparing post with slug " + (post.get("slug")) + " against the url slug " + params.post_slug);
            console.log(post.get("slug") === params._post_slug);
            return post.get("slug") === params.post_slug;
          });
          if (found.get("length") > 0) {
            return resolve(found[0]);
          } else {
            console.warn("failed to match against the slug found was:");
            console.dir(found.get("length"));
            return _this.store.find("post", params.post_slug).then((function(post) {
              return resolve(post);
            }), function(error) {
              return reject(error);
            });
          }
        };
      })(this));
    }
  });

  export default PostsPostRoute;

结果是：

store.filter似乎未返回预期的Array对象，但过滤仍在进行。

如何按slug过滤模型，以便ID能够获得模型的slug？
