我在轨道上有两个脚手架。第一个是项目，第二个是阶段。项目与舞台有一对多关联。我正在project#show表中渲染项目及其阶段，每当我单击编辑阶段按钮时，总是渲染和更新第一阶段编辑页面。我希望在用户单击舞台编辑时编辑当前阶段。
stages_controller.rb
def edit
@stage = Stage.find(params[:project_id])
@project = Project.find(params[:project_id])
end
def update
respond_to do |format|
if @stage.update(stage_params)
format.html { redirect_to project_path(@project), notice: 'Stage was successfully updated.' }
format.json { render :show, status: :ok, location: @stage }
else
format.html { render :edit }
format.json { render json: @stage.errors, status: :unprocessable_entity }
end
end
end
projects_controller.rb
def show
@project = Project.includes({stages: {tasks: :sub_tasks}}).find(params[:id])
@stages = @project.stages
end
路线.rb
resources :projects do
resources :stages do
