Rails 4 - 设计 - Heroku答案

【问题描述】：

我正试图让 rails 4 设置与设计一起工作（我已经接受了omniauth 的失败）。

我创建了一个全新的应用程序并将其部署在 heroku 中。

当我填写新的注册表单时，我从 heroku 收到一条错误消息，提示我查看日志。当我查看日志时，我得到了这个。我一点都不明白。任何人都可以在此日志中看到问题吗？

我的设置有：

用户.rb

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable,
         :zxcvbnable, :confirmable, :lockable

路线

 devise_for :users, #class_name: 'FormUser',
             :controllers => {
                :registrations => "users/registrations",
                # :omniauth_callbacks => "users/authentications"
                # :omniauth_callbacks => 'users/omniauth_callbacks',
           }

查看 - 导航

            <%= link_to("I'm new", new_user_registration_path) %>
            <span style= "padding-left: 10px">
              <%= link_to("Sign in", new_user_session_path) %>

用户/注册控制器

class Users::RegistrationsController < Devise::RegistrationsController 

  private
    def user_params
          params.require(:user).permit(:first_name, :last_name, :email, :password )
    end


end

按照下面的建议，我从 user.rb 中删除了 zxcvbnable，并从 config 文件夹中的 devise.rb 中删除了检查。

在我的 user.rb 中有验证检查是否存在名字和姓氏（仅此而已）。

我的新用户表单有：

<div class="form-inputs">
                            <%= f.input :first_name,  autofocus: true %>
                            <%= f.input :last_name %>
                            <%= f.input :email, placeholder: "Please use your work or university address" %>
                            <%= f.input :password, hint: ("#{@minimum_password_length} characters minimum" if @validatable), 
                                        :input_html => { class: 'estimate-password'} %>

                          </div>

当我重新启动服务器并重试时，我不断在新用户注册表单上收到错误通知，说名字和姓氏不能为空。我不断输入它们并重复该过程。

这快把我逼疯了。

【问题讨论】：

在我看来，当您创建用户时，好像某些验证失败了。（有效的？在第一行）。你试过没有 zxcvbnable 吗？
嗨，约翰内斯。我试着删除它。现在出现名字/姓氏不能为空的表单错误
jacopretorius.net/2014/03/… 可能会对您有所帮助。我没有时间检查，但你好像漏掉了什么。别担心，这个错误是进步 ;-)

【解决方案1】：

日志不确定；我会做几件事来确保一切正常：

确保您已迁移数据库

使用Devise sanitizers 作为参数

我个人认为您没有正确传递参数，因此验证失败。这可能会因您的数据库未迁移而更加复杂，因此User 模型甚至没有开始的属性。

我会做以下事情：

heroku run rake db:migrate

如果您已经创建了Devise migration，这会将所有更改迁移到您的生产数据库。

如果您还没有，则必须使用rails g devise:install 创建它，这将在本地创建文件。您需要确保将它们添加到您的 git 存储库，并将它们推送到您的服务器：

git add .
git commit -a -m "Devise Migration"
git push heroku master
heroku run rake db:migrate

这将确保您的数据库中有适当的属性（如果您还没有，请记住添加 first_name 和 last_name）。

一旦你确定你的数据库中有所有相关属性，你就需要整理好你的强参数。

Devise 使用params sanitizer 让您能够添加额外的参数。这与使用标准的strong params 方法相反，虽然可以，但不推荐。

所以我会做以下事情：

#app/controllers/users/registrations_controller.rb
class Users::RegistrationsController < Devise::RegistrationsController
   before_filter :configure_permitted_parameters, only: :create
   protected

   def configure_permitted_parameters
      devise_parameter_sanitizer.for(:sign_up) << [:first_name, :last_name]
   end
end
