当我单击按钮时出现错误，错误提示为 nil:NilClass 的未定义方法“strftime”

当我调试我的应用程序时，我看到了一些奇怪的东西

为什么他不接受我的可变事件，发表的描述我不明白。我错过了什么？

日历模型

class Calendar < ActiveRecord::Base
    attr_accessible :event, :published_on, :description, :user_id
    belongs_to :user#, :foreign_key => :user_id
end

用户模型

has_many :calendar#, :foreign_key => :user_id
  accepts_nested_attributes_for :calendar
  #attr_accessible :calendar_id
end

日历控制器

  def index
     @user = current_user
    #@content_calendars = @user.Calendar
    @content_calendars = @user.Calendar.all
    @content_calendars_by_dates = @content_calendars.group_by(&:published_on)
    @date = params[:date] ? Date.parse(params[:date]) : Date.today
  end

  def show
    @user = current_user
   # @calendar = @user.find_all_calendar_by()
    #  @tasks = @project.tasks.find_all_by_complete(false)
    @calendar = @user.calendar.find(params[:id])
  end





  def new

    @user = current_user
    @calendar = @user.calendar.new
   #@calendar = @user.calendar.build
  end

  # GET /calendars/1/edit
  def edit
    @user = current_user
    @calendar = @user.Calendar.find(params[:id])
  end

  # POST /calendars
  # POST /calendars.json
  def create

    @user = current_user
    @calendar = @user.calendar.new(params[:current_user])
    #@calendar = @user.Calendar.new(params[:calendar])
    if @calendar.save
       #redirect_to calendar_path(@user)
       redirect_to [@user,@calendar]
       #, notice: "L evenement a ete cree"
    else
      render :new
    end
  end

  # PUT /calendars/1
  # PUT /calendars/1.json
  def update
 @user = current_user
    @calendar = @user.Calendar.find(params[:id])
      if @calendar.update_attributes(params[:id])
          redirect_to [@user, @calendar]#, notice: "L article a ete mis a jour"
        else
          render :edit
      end
    end

  # DELETE /calendars/1
  # DELETE /calendars/1.json
  def destroy
 @user = current_user
    @calendar.destroy

    respond_to do |format|
      format.html { redirect_to calendars_url }
      format.json { head :no_content }
    end
  end

private
  def find_user 
    @user = current_user
    #@user = User.first
    #@user ||= User.find(session[:user_id]) if session[:user_id]
    #findession[:user_id]) 
  end

再次感谢您的帮助

我不太明白你在哪里遇到错误，所以请粘贴 Controller 的代码。根据您的解释，我觉得您应该获得如下所示的日历参数。我认为您的控制器应该从日历参数创建这样的对象：

@calender = Calender.new(params[:calender])
@calender.user_id = params[:user_id]

希望有帮助！！！
