doesn't seem to work with just :before

[socketwiz]

I have this in my model:

  validates :date_completed, :date => {
    :before => Time.now, :message => 'must be before today'
  }

But it doesn't matter what I enter for a date, I don't get any validation error. If I change it to:

  validates :date_completed, :date => {
    :after => Time.now, :message => 'must be after today'
  }

And enter a date before today, it works as expected. Any ideas?

The problem is that Time.now is evaluated when the class is loaded. You probably want to do this:

  validates :date_completed, :date => {
    :before => Proc.new { Time.now }, :message => 'must be before today'
  }

As noted at the readme :)

Yeah, I tried that before posting, but it doesn't work the way I would expect. When using Proc.new, I get a validation error, that says that I need to choose a date before today, even when choosing a date before today. In fact it doesn't matter what day I choose when using Proc.new, today, tomorrow, yesterday, it just keeps telling me to choose a date before today. The date I am passing in is of the format: 2011-06-01, would that be the problem? I tried 06-01-2011 but that didn't seem to matter either. I'm sure its something silly I'm doing wrong, just not sure what :(

None of these seem to work:

validates :date_completed, :date => {
    :before => Time.now, :message => 'must be before today'
  }

validates :date_completed, :date => {
    :before => Date.today, :message => 'must be before today'
  }

validates :date_completed, :date => {
    :before => Proc.new {Time.now}, :message => 'must be before today'
  }

validates :date_completed, :date => {
    :before => Proc.new{Date.today}, :message => 'must be before today'
  }

validates :date_completed, :date => {
    :before_or_equal_to => Proc.new {Time.now}, :message => 'must be before today'
  }

validates :date_completed, :date => {
    :before_or_equal_to => Proc.new{Date.today}, :message => 'must be before today'
  }

date_validator doesn't really care about the format, as long as its a Date, Time or DateTime. Are you sure you are passing a date object instead of a string?

Are you sure you are passing a date object instead of a string?

Hmm, I am pretty sure it comes through as a string. I'm just passing it through my form:

  <div class="field">
    <strong><label>Date Completed</label></strong>
    <%= f.text_field :completed_on, :class => "inputbox" %>
  </div>

action:

  def create
    @project.save
    respond_with(@project)
  end

I'm going to have to research how to make it a date object. Off the top of my head I'm thinking you have to open up the params array prior to a save or update in the action? Does that sound right? Or maybe there is a date_field that you use in the view?

Yes, you should you a date_input or time_input, this way Rails will autoconvert the value to a Date object. Here are some links to help you:

I see, well thank you for your help. I don't think I am going to be able to use this gem because I also want to use the jQuery datepicker: http://jqueryui.com/demos/datepicker/

But thank you for your time.
