undefined method 'validates_datetime' about validates_timeliness

[adzap]

Can you tell what version of Rails you are using? Also, please post a gist with the example model and tests, if you can.

Thanks for the follow up! Using rails 3.0.9, ruby 1.9.2, validates_timeliness 3.0.2 (full set of gems listed below)

Example Model

class Event  ActiveRecord::Base
    attr_accessible :event_name, :seats, :event_date, :cancel_date,
        :rsvp_date, :remaining_seats

    belongs_to :user

    validates :event_name,  :presence => true, 
                :length => { :maximum => 100 }
    validates :seats,   :numericality => { :only_integer => true }, 
                :inclusion => { :in => 1..30 }
    validates :user_id,     :presence => true

    # validate dates - using validates_timeliness gem
    validates_datetime :cancel_date, :on_or_before => :event_date
    validates_datetime :event_date, :on_or_after => lambda {Date.current}
    validates_datetime :rsvp_date,  :on_or_after => lambda {Date.current}, :on_or_before => :event_date

Example Controller

class EventsController  ApplicationController
    before_filter :authenticate
    before_filter :authorized_host, :only => [:edit, :update]
    before_filter :admin_user, :only => [:destroy, :index]

    def new
        @event = Event.new
        @title = "New Event"
    end

    def create
        @event = current_user.events.build(params[:event])
        if @event.save
            flash[:success] = "Event created!"
            redirect_to @event
        else
            render 'new'
        end 
    end

    def show
        @event = Event.find(params[:id])
        @host = User.find_by_id(@event.user_id)
        @title = "Event: #{@event.event_name}"          
    end

    def edit
        @title = "Edit Event"
        @event = Event.find(params[:id])
    end

    def update
        @event = Event.find(params[:id])
        if @event.update_attributes(params[:event])
            flash[:success] = "Event updated."
            redirect_to current_user
        else
            @title = "Edit Event"
            render 'edit'
        end
    end

    def index
        @title = "All events"
        @events = Event.paginate(:page => params[:page])
    end

    def destroy
        @event = Event.find(params[:id])
        if @event.destroy
            flash[:success] = "Event deleted"
            # later want to render index again or something
            # more useful to the admin
            redirect_to current_user
        end
    end

    private

        def authorized_host
            @event = current_user.events.find_by_id(params[:id])
            if @event.nil?
                flash[:notice] = "You must be the host of the event in order to edit it."
                redirect_to(current_user) 
            end
        end

        def admin_user
            redirect_to(current_user) unless current_user.admin?
        end

end

Tests
The validate dates tests work if I uncomment the validates_datetime lines in the model. Additionally, if I have those uncommented and create a new Event object in the console, it will give me the appropriate error message if I give an invalid date, indicating the validates_datetime seems to be working in that environment as well.

require 'spec_helper'

describe Event do
    
    before(:each) do
        @user = Factory(:user)
        @attr = { :event_name => "Test Name", :seats => 3, 
                :event_date => Time.now + 24*60*60*2, 
                :rsvp_date => Time.now + 24*60*60*2, 
                :cancel_date => Time.now - 24*60*60}
    end

    it "should create a new event instance given valid attributes" do
        @user.events.create!(@attr)
    end

        describe "validate dates" do
            it "should require valid datetime event_date" do
                @user.events.build(@attr.merge(:event_date => ' ')).
                        should_not be_valid
                @user.events.build(@attr.merge(:event_date => 1.years.ago)).
                        should_not be_valid
            end

Nothing seems obviously wrong. Though you are on an old version of the plugin. Try updating to 3.0.6 first and let me know.

As a tip, instead things like '24_60_60*2', you can use Time.now + 2.days.

Did you ever figure this out?
