将多个电子邮件添加到用户模型
我想在使用 devise 时使用 has_many 关系向用户模型添加多个电子邮件。这是这个问题的一点扩展：How can I configure Devise for Ruby on Rails to store the emails and passwords at other place not in用户模型？
User.rb has_many :电子邮件
Email.rb 所属：用户
在我的新/编辑表单中，如何设置 xxx.email 的 fields_。我可以看到 devise 的注册页面使用“资源”。当我尝试以下代码时，它只是跳过电子邮件字段。
= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|
= devise_error_messages!
%table{:style=>"width:400px;"}
-fields_for resource.email do |emails|
%tr
%td
= emails.label :email
%td
= emails.email_field :email
%tr
%td
= f.label :password ...
%tr
%td
= f.label :firstname ....
另外，谁来修改设备控制器中的操作？
在这种情况下，整个电子邮件块不会出现。
谢谢
I want to add multiple emails to the user model while using devise, using a has_many relationship. It's a bit of an extension to this question: How can I configure Devise for Ruby on Rails to store the emails and passwords somewhere other than in the user model?
User.rb
has_many :emails
Email.rb
belongs_to :user
In my new/edit form for devise how do I set up the fields_for xxx.email. I can see that the registration page from devise uses "resource". When I try the following code it just skips the email field.
= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|
= devise_error_messages!
%table{:style=>"width:400px;"}
-fields_for resource.email do |emails|
%tr
%td
= emails.label :email
%td
= emails.email_field :email
%tr
%td
= f.label :password ...
%tr
%td
= f.label :firstname ....
Also, who do you modify the actions in the controller for devise?
In this case, the entire email block does not apear.
Thanks

fields_for需要一些数据来创建字段。对于新记录，通常需要执行诸如resource.emails.build之类的操作来创建要显示的第一条记录。而且，我认为您应该使用
fields_for(resource.emails) 执行 |email|。The helper
fields_forneed some data to create the fields. With new records, usually is needed you do something likeresource.emails.buildto create a first record to be showed.And also, I think you should use
fields_for(resource.emails) do |email|.
