date_validator

A simple date validator for Rails. Should be compatible with all latest Rubies.

$ gem install date_validator

And I mean simple. In your model:

validates:expiration_date,date: true

or with some options, such as:

validates:expiration_date,date: {after: Proc.new{Time.now},before: Proc.new{Time.now + 1.year}}# Using Proc.new 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 datevalidates:expiration_date,date: {after: :packaging_date}

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

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

validates:start_date,date: {after: Proc.new{Date.today},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.
