Question

我有一个标准内容的用户注册表单。它工作正常，但现在它完全坏了，错误消息完全没有用。几个星期前我跳进了这个现有的应用程序。即使我在将任何代码放入此项目之前检出提交，表单仍然不起作用。通过'不工作'，我的意思是它会抛出错误，好像表格完全是空白的（'请输入电子邮件'，'请输入密码'），当他们肯定不是空白时。这是相关的代码......

MODEL：

include FormsHelper
class User < ActiveRecord::Base

  attr_accessible :email, :password, :password_confirmation, :remember_me,
                  :first_name, :last_name, :gender, :time_zone, :state,
                  :birthday, :oauth_id, :oauth_provider_display_name,
                  :admin, :vagrant, :favorite_shoe, :race_manager, :auto_submission,
                  :country

控制器：

  def create
    build_resource

    if resource.save

      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_in(resource_name, resource)
        respond_with resource, :location => after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
        expire_session_data_after_sign_in!
        respond_with resource, :location => after_inactive_sign_up_path_for(resource)
      end
    else

      Rails.logger.info(resource.errors.inspect)
      flash.now[:error] = I18n.t('activerecord.template.body')
      respond_with resource
    end
  end

查看

<%= f.input :email, :required => true,
                    :autofocus => true,
                    :input_html => { :autocomplete => 'off' },
                    :as => 'email' %>
<% if resource.oauth_id.present? %>
  <%#
    Check if we're coming here from an OAuth-typ registration. The value here doesn't really matter
    because it'l be auto-generated again on create. This is just for form validation purposes.
  %>
  <%= f.hidden_field :password %>
  <%= f.hidden_field :password_confirmation,
                     :value => f.object.password %>
<% else %>
  <%= f.input :password,
              :required => true,
              :hint => controller.controller_name == 'account' ? "Leave blank if you don't want to update your password." : nil,
              :input_html => { :value => f.object.password, :autocomplete => 'off' } %>
  <%= f.input :password_confirmation,
              :label => "Confirm password",
              :required => true,
              :input_html => { :value => f.object.password_confirmation, :autocomplete => 'off' } %>
<% end %>
<%= f.input :first_name, :required => true %>
<%= f.input :last_name, :required => true %>

这是日志输出

这里令人困惑的是，参数明显地出现在正确的位置。但后来它只是回滚，模型上没有任何内容。我甚至关闭了所有验证，我仍然收到错误，说需要填写电子邮件和密码（当它们显然已经填写时，如params所示）。

非常感谢任何想法！这个让我疯狂。谢谢！

更新：根据用户的建议，我检查了宝石问题。在我做任何事之前我回滚过提交，然后运行bundle install。唯一的变化是来自3.0的“Paperclip”更新 - ＆gt; 3.5.2。但这并没有解决任何问题。和以前一样的问题。然而，通过验证，它确实产生了这个日志输出......

   (0.3ms)  BEGIN
  User Exists (0.5ms)  SELECT 1 AS one FROM `users` WHERE `users`.`email` = BINARY '' LIMIT 1
   (0.7ms)  ROLLBACK

请注意，该电子邮件是BINARY''。通常情况下，实际的电子邮件地址应显示在“是”的位置。而且，params肯定会在日志中完全显示为类型。然而，当它进行SQL检查时，字段全部为空。有什么想法吗？

Answer 1

猜测你正在使用Devise，因为控制器代码几乎与Devise::RegistrationsController相同。（current code here）

几乎 - 除了build_resource传递传入参数的部分。

您可能想要检查应用程序的工作副本（其他开发人员？生产？）正在使用的Devise版本，因为某些旧版本的build_resource方法不需要参数。

Rails形成了神秘的错误。即使存在params，每次都会回滚
