A simple date validator for Rails 3. Compatible with Ruby 1.8.7, 1.9.2 and Rubinius 1.2.2.

$ gem sources -a
$ gem install date_validator

And I mean simple. In your model:

validates :expiration_date,
          :date => {:after => { },
                    :before => { + 1.year } }
# Using prevents production cache issues

If you want to check the date against another attribute, you can pass it a Symbol instead of a block:

# Ensure the expiration date is after the packaging date
validates :expiration_date,
          :date => {:after => :packaging_date}

For now the available options you can use are :after, :before, :after_or_equal_to and :before_or_equal_to.

If you want to specify a custom message, you can do so in the options hash:

validates :start_date,
  :date => {:after =>, :message => 'must be after today'},
  :on => :create

Pretty much self-explanatory! :)

If you want to make sure an attribute is before/after another attribute, use:

validates :start_date, :date => {:before => :end_date }

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send us a pull request. Bonus points for topic branches.
