我试图在模式窗口中使用 ajax 表单来允许我的用户编辑/创建新对象，我遇到的问题是错误没有被显示。

在我的控制器中，我有以下内容

 def create
    @user = User.find(current_user)
    @players = User.where(:team_id => current_user[:team_id]).all
    #params[:event][:datetime] = "#{params[:event][:date]} #{params[:event][:time]}"
    @event = Event.new(params[:event])
    respond_to do |format|
      if @event.save
        #Notifier.event_added(@event,@user).deliver
        format.html { redirect_to(events_url,
                                  :notice => "#{event_display_c(@event.event)} vs #{@event.opponent.name} was successfully created.") }
        format.js { @events = Event.all }
      else
        format.html { render :action => "new" }
        format.js { render :json => @event.errors, :status => :unprocessable_entity }
      end
    end
  end

在我的 create.js.erb 我有

$("#events_list").replaceWith("<%= escape_javascript render('events_list') %>");

在我的部分我有

 - if @event.errors.any?
  .alert-box.error
    %a.close{:href => ''} ×
    %strong Error:
    = pluralize(@event.errors.count, 'error')

    %ul
      - @event.errors.full_messages.each do |msg|

控制台输出什么

respond_to将块更改为

respond_to do |format|
  if @event.save
    #Notifier.event_added(@event,@user).deliver
    format.html { redirect_to(events_url,
                              :notice => "#{event_display_c(@event.event)} vs #{@event.opponent.name} was successfully created.") }
    format.js { @events = Event.all }
  else
    format.html { render :action => "new" }
    format.js
  end
end

并更改create.js.erb为

`$("#events_list").html("<%= escape_javascript render('events_list') %>")`

因为你没有#events_list那个部分的 div
