Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/validation_extender
. To experiment with that code, run bin/console
for an interactive prompt.

And then execute:
$ bundle
Or install it yourself as:
$ gem install validation_extender
class User
include ActiveModel::Model
attr_accessor :name
attr_accessor :email
end
class UserForm
include ValidationExtender
extend_on :model
add_validation :name, presence: true, length: { maximum: 255 }
add_validation :email, format: { with: %r[@] }
def initialize(model)
@model = model
end
end
user = User.new(name: nil, email: "[email protected]")
uf = UserForm.new(user)
uf.save
uf.errors.any?
#=> true
class User
include ActiveModel::Model
attr_accessor :name
attr_accessor :email
end
module UserValidations
include ValidationExtender
add_validation :name, presence: true, length: { maximum: 255 }
add_validation :email, format: { with: %r[@] }
end
user = User.new(name: nil, email: "[email protected]")
user.extend(UserValidations)
user.save
user.errors.any?
#=> true
