我正在使用acts_as_votable gem。

这是我投票时的日志：

   (0.3ms)  SELECT COUNT(*) FROM "votes" WHERE "votes"."votable_id" = $1 AND "votes"."votable_type" = $2  [["votable_id", 11], ["votable_type", "Story"]]
   (0.4ms)  SELECT COUNT(*) FROM "votes" WHERE "votes"."votable_id" = $1 AND "votes"."votable_type" = $2 AND "votes"."vote_flag" = 't' AND "votes"."vote_scope" IS NULL  [["votable_id", 11], ["votable_type", "Story"]]
   (0.3ms)  SELECT COUNT(*) FROM "votes" WHERE "votes"."votable_id" = $1 AND "votes"."votable_type" = $2 AND "votes"."vote_flag" = 'f' AND "votes"."vote_scope" IS NULL  [["votable_id", 11], ["votable_type", "Story"]]
   (0.3ms)  BEGIN
   (0.2ms)  COMMIT
Completed 500 Internal Server Error in 34ms (Views: 1.6ms | ActiveRecord: 8.0ms)

这是我的 JS：

$('.story-vote-up').on("ajax:success", function(evt, data, status, xhr) {
    console.log(data);
  }).on("ajax:error", function(evt, data, status, xhr){
    console.log(data);
  });

和link_to：

<%= link_to 'Vote', vote_story_path(story), method: :put, remote: true %>

和我的控制器动作：

  def vote
    @story = Story.find(params[:id])
    respond_to do |format|
        if @story.liked_by default_persona
          format.html { redirect_to @story, notice: 'Voted' }
          format.json { render json: @story, status: :voted, location: @story }
        else
          format.html { redirect_to @story, notice: 'Error voting' }
          format.json { render json: @story.errors, status: :unprocessable_entity }
        end
      end
  end

我能够在我想要的响应中获取数据，但为什么状态为 500？

对于您返回的成功分支，status: :voted它会导致 500 作为其未注册 Rails 的状态代码。

这是整个 rails 符号到代码的映射（2008 链接）http://www.codyfauser.com/2008/7/4/rails-http-status-code-to-symbol-mapping

或者干脆在 number 中使用所需的状态码status: 200。
