A simple date validator for Rails. Should be compatible with all latest Rubies (>2.2, includes Ruby 3.0).
$ 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 date
validates :expiration_date,
date: { after: :packaging_date }
or access attributes via the object being validated directly (the input to the Proc):
validates :due_date,
date: { after_or_equal_to: Proc.new { |obj| obj.created_at.to_date }
# The object being validated is available in the Proc
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 }
If you want to allow an empty date, use:
validates :optional_date, date: { allow_blank: true }
