Question

这在生产中完美运行，但一直在搞乱部署。奇怪的是，我使用相同的代码设置了类似的另一个模型，它在部署时工作正常。

控制器：

  def new
        @task = Task.new
      end

    def create
        @task = Task.new(task_params)
        @task.user_id = current_user[:id]
        respond_to do |format|
          if @task.save
            format.html { redirect_to line_url(@task.lines_id), notice: 'Task was successfully created.' }
            format.json { render :show, status: :created, location: @task }
          else
            format.html { render :new }
            format.json { render json: @task.errors, status: :unprocessable_entity }
          end
        end
      end

 private
    # Use callbacks to share common setup or constraints between actions.
    def set_task
      @task = Task.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def task_params
      params.require(:task).permit(:title, :description, :priority, :lines_id, :scene, :icon, :icon_color, :fulltext, :doclink, :user_id)
    end
  end

错误：

同时，在生产中，提交没有问题：

   (133.6ms)  commit transaction

我仔细检查以确保我在部署时运行了rake db：migrate。

我不认为这是current_user的问题，因为我肯定以用户身份登录 - 我甚至无法访问新表单，因为我需要current_user来查看表单。

真的很感激你可能有的任何见解。

Answer 1

我建议将user_id添加为新形式的隐藏字段，如：

<%= f.hidden_field :user_id, current_user.id %>

或者更好的方法：

@task = current_user.task.new(task_params)

因为这是一种更好的方法＆amp;将避免这种错误情况。

获取user_id的NoMethodError，但仅限于部署（Rails）
