新添加的列的数据未保存到数据库
[英] Newly added column's data not being saved to DB

问题描述
我在 Rails 4 应用程序中使用 Devise 进行用户身份验证.最近我向 User 模型添加了两个新列.它们是 first_name 和 last_name. 然后我用这两个属性的字段更新了登录表单.但是，当我测试创建新用户时，两者都没有保存到数据库中.我认为这可能是一个批量分配问题，但我没有收到任何类型的数据库错误.用户已成功创建，但仅存储原始属性(电子邮件、密码和 password_confirmation).任何人都可以帮忙吗?
这是我的表单的代码:
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|％＞<%= devise_error_messages!％＞<div class="small-10 small-offset-0 列"><div class="row"><div class="small-2 columns"><%= f.label :first_name, class: 'right inline' %>
<div class="small-4 columns"><%= f.text_field :first_name, id: 'right-label' %>
<div class="small-6 columns"><!-- 空白区域-->
<div class="row"><div class="small-2 columns"><%= f.label :last_name, class: 'right inline' %>
<div class="small-4 columns"><%= f.text_field :last_name, id: 'right-label' %>
<div class="small-6 columns"><!-- 空白区域-->
<div class="row"><div class="small-2 columns"><%= f.label :email, class: 'right inline' %>
<div class="small-4 columns"><%= f.email_field :email, id: 'right-label' %>
<div class="small-6 columns"><!-- 空白区域-->
<div class="row"><div class="small-2 columns"><%= f.label :password, class: 'right inline' %>
<div class="small-4 columns"><%= f.password_field :password, id: 'right-label' %>
<div class="small-6 columns"><!-- 空白区域-->
<div class="row"><div class="small-2 columns"><%= f.label :password_confirmation, class: 'right inline' %>
<div class="small-4 columns"><%= f.password_field :password_confirmation, id: 'right-label' %>
<div class="small-6 columns"><!-- 空白区域-->
<div class="row"><div class="small-2 columns"><!--占位符-->
<div class="small-10 列"><%= f.submit "Create account", class: 'button small' %>
<div class="row"><div class="small-2 columns"><!--占位符-->
<div class="small-10 列"><%= 渲染设计/共享/链接"%>
<div class="small-3 columns"><!-- 这里什么都没有-->
<%结束%>
来自控制台的关于我的模型的信息显示已添加属性:
User(id: integer, email: string, encrypted_password: string, reset_password_token: string, reset_password_sent_at: datetime, remember_created_at: datetime, sign_in_count: integer, current_sign_in_at: datetime, last_sign_in_at: datetime, current_sign_in_ip: string, last_sign_in字符串，created_at:日期时间，updated_at:日期时间，first_name:字符串，last_name:字符串)
解决方案
根据 Rails 4 的强参数，您需要让设计知道这些新参数现在是允许的.您可以将以下内容添加到您的应用程序控制器:
class ApplicationController <动作控制器::基础before_action :configure_permitted_parameters, if: :devise_controller?受保护def configure_permitted_parametersdevise_parameter_sanitizer.for(:sign_up) <<:first_name <<:姓结尾结尾

I am using Devise for user authentication in my Rails 4 app. Recently I added two new columns to the User model. They are first_name and last_name. I then updated the signin form with fields for both of these attributes. However, neither are being saved to the database when I test creating a new user. I thought it might be a mass assignment problem but I'm not getting any kind of database error. The user is successfully created but only the original attributes (email, password, and password_confirmation) are being stored. Can anyone help?
Here is the code for my form:
<div class="row">
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="small-10 small-offset-0 columns">
<div class="row">
<div class="small-2 columns">
<%= f.label :first_name, class: 'right inline' %>
</div>
<div class="small-4 columns">
<%= f.text_field :first_name, id: 'right-label' %>
</div>
<div class="small-6 columns">
<!-- empty space -->
</div>
</div>
<div class="row">
<div class="small-2 columns">
<%= f.label :last_name, class: 'right inline' %>
</div>
<div class="small-4 columns">
<%= f.text_field :last_name, id: 'right-label' %>
</div>
<div class="small-6 columns">
<!-- empty space -->
</div>
</div>
<div class="row">
<div class="small-2 columns">
<%= f.label :email, class: 'right inline' %>
</div>
<div class="small-4 columns">
<%= f.email_field :email, id: 'right-label' %>
</div>
<div class="small-6 columns">
<!-- empty space -->
</div>
</div>
<div class="row">
<div class="small-2 columns">
<%= f.label :password, class: 'right inline' %>
</div>
<div class="small-4 columns">
<%= f.password_field :password, id: 'right-label' %>
</div>
<div class="small-6 columns">
<!-- empty space -->
</div>
</div>
<div class="row">
<div class="small-2 columns">
<%= f.label :password_confirmation, class: 'right inline' %>
</div>
<div class="small-4 columns">
<%= f.password_field :password_confirmation, id: 'right-label' %>
</div>
<div class="small-6 columns">
<!-- empty space -->
</div>
</div>
<div class="row">
<div class="small-2 columns">
<!--placeholder -->
</div>
<div class="small-10 columns">
<%= f.submit "Create account", class: 'button small' %>
</div>
</div>
<div class="row">
<div class="small-2 columns">
<!--placeholder -->
</div>
<div class="small-10 columns">
<%= render "devise/shared/links" %>
</div>
</div>
</div>
<div class="small-3 columns">
<!-- nothing here -->
</div>
<% end %>
</div>
And the info on my model from the console showing that the attributes have been added:
User(id: integer, email: string, encrypted_password: string, reset_password_token: string, reset_password_sent_at: datetime, remember_created_at: datetime, sign_in_count: integer, current_sign_in_at: datetime, last_sign_in_at: datetime, current_sign_in_ip: string, last_sign_in_ip: string, created_at: datetime, updated_at: datetime, first_name: string, last_name: string)
解决方案
You need to let devise know that these new parameters are now permitted, in accordance with Rails 4's strong parameters. You can add the following to your application controller:
class ApplicationController < ActionController::Base
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) << :first_name << :last_name
end
end
For more information on using Rail 4's strong parameters with devise, see the Strong Parameters section of the Devise README.
