我从 client_side_validations 页面复制了代码。我有错误
undefined method validates_email for #<Class:0x007ff3382428a8>
当我放入includes ::Validations我的模型时，这个错误消失了，但验证根本不起作用。
应用程序/验证器/email_validator.rb
class EmailValidator < ActiveModel::EachValidator
def validate_each(record, attr_name, value)
unless value =~ /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i
record.errors.add(attr_name, :email, options.merge(:value => value))
end
end
end
# This allows us to assign the validator in the model
module ActiveModel::Validations::HelperMethods
def validates_email(*attr_names)
validates_with EmailValidator, _merge_attributes(attr_names)
end
end
配置/语言环境/en.yml
# config/locales/en.yml
en:
errors:
messages:
email: "Not an email address"
应用程序/资产/javascripts/rails.validations.customValidators.js
// The validator variable is a JSON Object
// The selector variable is a jQuery Object
window.ClientSideValidations.validators.local['email'] = function(element, options) {
// Your validator code goes in here
if (!/^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i.test(element.val())) {
// When the value fails to pass validation you need to return the error message.
// It can be derived from validator.message
return options.message;
}
}
模型/comment.rb
class Comment < ActiveRecord::Base
attr_accessible :content, :email, :ip, :name, :post_id
belongs_to :post
validates_presence_of :content, :email, :post_id, :name
validates_email :email
end
