I posted this on comp.lang.ruby and thought it would be in my best
interest to post it here too.
I’ve written a custom validation method (to validate an email
address). It looks like
module ActiveRecord
module Validations
module ClassMethods
def validates_as_email
...
end
end
end
end
I’ve put this code in app/lib/custom_validations.rb
Now, I’m trying to write a unit test but I’m running into problems.
One attempt at a unit test looks like
require File.dirname(FILE) + ‘/…/test_helper’
require ‘lib/custom_validations’
class CustomValidationsTest < Test::Unit::TestCase
def test_validates_as_email
email = “[email protected]”
assert validates_as_email( email )
end
end
This throws a
NoMethodError: undefined method `validates_as_email’ for
#CustomValidationsTest:0x314bd80
It looks to me like the test is looking for the validates_as_email
method to be defined in CustomValidationsTest rather than finding it
in lib/custom_validations.rb
So, I tried this
require File.dirname(FILE) + ‘/…/test_helper’
require ‘lib/custom_validations’
class CustomValidationsTest < Test::Unit::TestCase
def test_validates_as_email
email = “[email protected]”
assert
ActiveRecord::Validations::ClassMethods.validates_as_email( email )
end
end
And I got this error
NoMethodError: undefined method `validates_as_email’ for
ActiveRecord::Validations::ClassMethods:Module
What am I missing? I’ll bet it’s something simple, but I just can’t
figure out what’s wrong. Thanks for the help.
