Question

有关如何将日期格式化为mm/dd/yy的任何建议？此选项不起作用：

$('#datepicker').datepicker({ dateFormat: 'dd-mm-yy' });

我遇到的问题是在保存日期之后我又回去编辑它，它将日期显示为1901，因为它正在解析2016-01-01。如何将日期作为mm/dd/yy存储在数据库中？好像我需要将格式添加到<%= f.text_field :jobdate, "data-provide" => 'datepicker', class: "form-control" %>

class AppointmentsController < ApplicationController
  before_action :set_appointment, only: [:show, :edit, :update, :destroy]

  # GET /appointments
  # GET /appointments.json
  def index
    @appointments = Appointment.all
  end

  # GET /appointments/1
  # GET /appointments/1.json
  def show
  end

  # GET /appointments/new
  def new
    @appointment = Appointment.new
  end

  # GET /appointments/1/edit
  def edit
  end

  # POST /appointments
  # POST /appointments.json
  def create
    @appointment = Appointment.new(appointment_params)

    respond_to do |format|
      if @appointment.save

        format.html { redirect_to @appointment, notice: 'Appointment was successfully created.' }
        format.json { render action: 'show', status: :created, location: @appointment }
      else
        format.html { render action: 'new' }
        format.json { render json: @appointment.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /appointments/1
  # PATCH/PUT /appointments/1.json
  def update

    respond_to do |format|
      if @appointment.update(appointment_params)

        format.html { redirect_to @appointment, notice: 'Appointment was successfully updated.' }
        format.json { render action: 'show', status: :ok, location: @appointment }
      else
        format.html { render action: 'edit' }
        format.json { render json: @appointment.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /appointments/1
  # DELETE /appointments/1.json
  def destroy
    @appointment.destroy
    respond_to do |format|
      format.html { redirect_to appointments_url }
      format.json { head :no_content }
    end
  end

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

    # Never trust parameters from the scary internet, only allow the white list through.
    def appointment_params
      params.require(:appointment).permit(:First_Name, :last_name, :phone, :cellphone_yes, :cell_provider, :jobdate, :time_start, :time_stop, :status, :location, :service, :sales_person, :technician, :year, :make, :model, :vehicle_type, :cost, :glass_number, :glass_ordered, :portland, :pilkington, :glass_type, :glass_type_other, :how_paid, :paid_type, :insurance, :insurance_company, :vin, :referral, :heated_wiper, :rain_sensor, :condensation_sensor, :electrochromatic, :lane_departure, :molding_needed, :molding_number, :molding_ordered, :other_phone, :work_business_name, :address1, :address2, :city, :state, :zip, :notes)
    end
end

jQuery datepicker会将日期作为文本发送回rails应用程序;一旦您对屏幕上显示日期的方式感到满意，您可以使用strptime在控制器中正确解析它。在您的情况下，如果您想要mm/dd/yy，您只需更改收到的参数，如下所示：

def appointment_params
  original_params = params.require(:appointment).permit(:First_Name, :last_name, :phone, :cellphone_yes, :cell_provider, :jobdate, :time_start, :time_stop, :status, :location, :service, :sales_person, :technician, :year, :make, :model, :vehicle_type, :cost, :glass_number, :glass_ordered, :portland, :pilkington, :glass_type, :glass_type_other, :how_paid, :paid_type, :insurance, :insurance_company, :vin, :referral, :heated_wiper, :rain_sensor, :condensation_sensor, :electrochromatic, :lane_departure, :molding_needed, :molding_number, :molding_ordered, :other_phone, :work_business_name, :address1, :address2, :city, :state, :zip, :notes)
  original_params.merge({jobdate: Date.strptime(original_params.delete(:jobdate), '%m/%d/%y')})
end

您还应该将正确格式化的日期发送到表单。要做到这一点，最简单的可能只是设置字段值而不是使用格式：

<%= f.text_field :jobdate, "data-provide" => 'datepicker', :value => (@model_instance.jobdate || Date.today).strftime("%m/%d/%y") %>

您还必须与jQuery datepicker配置中的格式保持一致：

$( "#datepicker" ).datepicker({
  dateFormat: "mm/dd/yy"
});

datepicker没有格式化为mm / dd / yy
