Question

所以我正在尝试使用约会gem （http://www.rubydoc.info/gems/appointments/1.3.3）。我完全按照文档说的那样完成，并且我不断收到以下错误：

ActiveRecord::StatementInvalid in AppointmentsController#index

SQLite3::SQLException: no such column: appointments.date: SELECT "appointments".* FROM "appointments" WHERE "appointments"."date" IS NULL

app/controllers/appointments_controller.rb:6:in `index'

  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true

end

appointments_controller.rb

class AppointmentsController < ApplicationController

  def index
    date_from_ajax = params[:matched_date]
    reduce = Appointment.where(:date => date_from_ajax)
    hour_on_date = reduce.collect {|x| x.hour}
    @new_dates = hour_on_date
    render :layout => false
  end

  def new
    @appointments = Appointment.create
      respond_to do |format|
        format.html
        format.js
        end
     end


  def create
     @appointment = Appointment.create(params[:appointments])
      if @appointment.save
        redirect_to new_appointment_path
      else
        err = ''
        @appointment.errors.full_messages.each do |m|
        err << m
      end

        redirect_to new_appointment_path, :flash => { :alert => "#{err}, please try again" }
      end
    end

  private

    def appointment_params
      params.require(:appointment).permit(:date, :hour, :done)
    end
end

appointments.rb

class Appointment < ActiveRecord::Base

validates :date,  :presence => true
validates :hour,  :presence => true,
                  :uniqueness => {:scope => :date}
end

有没有人可以帮我解决这个问题。
