【问题描述】：
我最近发布了一个问题，寻求有关如何让 client_side_validations gem 与 Devise 一起使用的帮助。我收到了 gem 的作者的及时回复，尝试使用不同版本的 gem，这暂时解决了我的问题。
但是我现在只能触发电子邮件地址字段。我可以从表单后注入的 javascript 中看到它正在引用表单中的其他字段，但它似乎没有触发任何错误消息。这是我的代码：
宝石文件
gem 'client_side_validations', :github => 'bcardarella/client_side_validations', :branch => '3-2-stable'
用户.rb
validates :email, :presence => { :message => "An email address is required."}, :uniqueness => { :message => "Email address has already been taken."}
validates :first_name, :presence => { :message => "A first name is required."}
validates :last_name, :presence => { :message => "A last name is required."}
validates :privacy_policy, :acceptance => { :message => "Please accept the Privacy policy."}
表格
<h1>Sign up</h1>
<%= link_to(user_omniauth_authorize_path(:facebook), :class => "btn btn-primary btn-fb-large btn-large") do %>
<div class="icon"><span></span><i class="icon-facebook"></i></div><div class="divider"></div>Sign in with Facebook
<% end %>
<%= form_for(resource, :validate => true, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= f.label :first_name %>
<%= f.text_field :first_name, :validate => true %>
<%= f.label :last_name %>
<%= f.text_field :last_name, :validate => true %>
<%= f.label :email %>
<%= f.email_field :email %>
<%= f.label :password %>
<%= f.password_field :password, :validate => true %>
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>
<%= f.label :privacy_policy, :class => 'checkbox' do %>
<%= f.check_box :privacy_policy %>I agree to the <%= link_to "Privacy policy", privacy_path %><% end %>
<%= f.submit "Sign up", :class => 'btn' %>
<% end %>
注入脚本

//]]></script>
我已经尝试了在 Google 上可以找到的所有搜索结果，并探索了与 Devise 相关的所有途径，但没有运气。
我在浏览器控制台中没有收到任何 JS 错误。
任何帮助将不胜感激。
【问题讨论】：
-
您是否尝试取消注释
config/initalizers/devise.rb中的代码块？ -
感谢@david 的回复。哪些部位？我需要其中一些用于邮件和 Facebook 身份验证配置。
-
客户端验证文档声明如下：初始化程序包括一个注释掉的 ActionView::Base.field_error_proc。取消注释以使您的错误消息与输入字段内联。我建议您不要使用类似于 error_messages_for 的解决方案。客户端验证永远不会支持呈现这种类型的错误呈现。如果您想保持客户端呈现的验证错误消息和服务器端呈现的验证错误消息之间的一致性，请使用 config/initializers/client_side_validations.rb 中的内容
-
我认为您可能指的是
config/initializers/client_side_validations.rb，在这种情况下，我已取消注释所需的代码。验证有效，但仅在电子邮件字段上有效。
