没有路由匹配{：action =>“edit”，：controller =>“events”}缺少必需的键：

我正在使用Rails应用程序，在尝试添加“编辑事件”链接后，我收到了以下错误。

No route matches {:action=>"edit", :controller=>"events"} missing required keys: [:id] 

下面是我的index.html.haml

 .event_con %h1 Things you've done - @events_own.each do |event| .event_title = event.activity .event_rating %strong Rating : = event.rating &#47 10 .event_when %strong Started : = event.time.to_s(:short) .event_end %strong Ended : = event.timetwo.to_s(:short) .event_notes %strong Notes : = event.notes = link_to "Edit", edit_event_path 

这是我的事件控制器：

 class EventsController  current_user.id).order("created_at DESC") @event = Event.new end # GET /events/1 # GET /events/1.json def show end # GET /events/new def new @event = Event.new config.time_zone = 'London' end # GET /events/1/edit def edit end # POST /events # POST /events.json def create @event = Event.new(event_params) @event.userid = current_user.id config.time_zone = 'London' respond_to do |format| if @event.save format.html { redirect_to @event, notice: 'Event was successfully created.' } format.json { render action: 'show', status: :created, location: @event } else format.html { render action: 'new' } format.json { render json: @event.errors, status: :unprocessable_entity } end end end # PATCH/PUT /events/1 # PATCH/PUT /events/1.json def update respond_to do |format| if @event.update(event_params) format.html { redirect_to @event, notice: 'Event was successfully updated.' } format.json { head :no_content } else format.html { render action: 'edit' } format.json { render json: @event.errors, status: :unprocessable_entity } end end end # DELETE /events/1 # DELETE /events/1.json def destroy @event.destroy respond_to do |format| format.html { redirect_to events_url } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_event @event = Event.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def event_params params.require(:event).permit(:activity, :time, :rating, :notes, :userid, :id, :timetwo) end end 

如果有人能够弄清楚这个bug我会非常感激。 🙂

您需要传递您想要编辑的event的id 。 目前您没有传递它导致错误

 No route matches {:action=>"edit", :controller=>"events"} missing required keys: [:id] 

要解决此问题，请使用以下更新的链接，它应该存在于@events_own的迭代中

 = link_to "Edit", edit_event_path(event) 

这将为每个event正确创建edit链接。
