Tableless validation in Rails 4.2 -

i trying validate form, not bound real model, did following:

a model

class formrequest      include activemodel::model      attr_accessor :email      validates :email, presence: true, email: true  end

and method in controller

# form shown def index     @form_request = formrequest.new end

but when load page error:

unknown validator: 'emailvalidator'

what did miss?

you don't have email: true validator.

to validate email can use regular expression:

valid_email = /\a[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i validates :email, presence: true, format: { with: valid_email }
