Question

Rails 4.2.8

user.rb

ORDER BY 
IF(type='30', extra, 0) DESC,
IF(type !='30', extra, 0) ASC

customer.rb

class User < ActiveRecord::Base
   devise :database_authenticatable, :registerable, :rememberable,
         :validatable, :encryptable, :omniauthable, omniauth_providers: [:facebook], encryptor: :restful_authentication_sha1
   attr_accessible :email, :name, :password, :password_confirmation, :is_admin, :is_master

   has_one :customer
   accepts_nested_attributes_for :customer
end

customers_contoller.rb

class Customer < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user
end

customers / edit.html.erb

class CustomersController < ApplicationController
  def edit
    @customer = current_user.customer
  end

  def update
    @customer = current_user.customer
    @customer.update customer_params
    render 'edit'
  end

  private

  def customer_params
    params.require(:customer).permit(:first_name, :last_name, :phone, user_attributes: [:email, :password, :password_confirmation])
  end
end

这就是我在日志中看到的内容

<%= form_for @customer, html: { class: 'checkout-attributes profile-form' } do |f| %>
  <div class="row">
    <div class="col-sm-6">
      <span class="help-block">First Name</span>
      <%= f.text_field :first_name, class: 'form-control' %>
    </div>
    <div class="col-sm-6">
      <span class="help-block">Last Name</span>
      <%= f.text_field :last_name, class: 'form-control' %>
    </div>

    <div class="col-sm-12">
      <span class="help-block">Email</span>
      <%= fields_for :user, @customer.user do |u| %>
      <%= u.email_field :email, class: 'form-control' %>
      <% end %>
    </div>

    <div class="col-sm-12">
      <span class="help-block">Phone Number</span>
      <%= f.text_field :phone, class: 'form-control' %>
    </div>
    <div class="col-sm-12">
      <span class="help-block">Password</span>
      <%= fields_for :user, @customer.user do |u| %>
      <%= u.password_field :password, class: 'form-control' %>
      <% end %>
    </div>
    <div class="col-sm-12">
      <span class="help-block">Confirm Password</span>
      <%= fields_for :user, @customer.user do |u| %>
      <%= u.password_field :password_confirmation, class: 'form-control' %>
      <% end %>                      
    </div>
  </div>
<% end %>

此外，我看到 customer_params 方法提供过滤（无用户部分）哈希 {“first_name”=＆gt;“杰克”，“last_name”=＆gt;“Drobazko”，“手机“=＆gt;” 中5084427293" }

那么如何使其有效？

根据您的日志文件：

＆＃34; image＆＃34; =＆gt;＆＃34;＆＃34;，＆＃34;客户＆＃34; =＆gt; {＆＃34; first_name＆＃34; =＆gt;＆＃34;杰克＆＃34 ;, ＆＃34; last_name＆＃34; =＆gt;＆＃34; Drobazko＆＃34;，＆＃34; phone＆＃34; =＆gt;＆＃34; 5084427293＆＃34;}，＆＃34;用户＆＃34; =＆gt; {＆＃34;电子邮件＆＃34; =＆gt;＆＃34; ddd @fff.com＆＃34;，＆＃34;密码＆＃34; =＆gt; ＆＃34; [FILTERED]＆＃34 ;, ＆＃34; password_confirmation＆＃34; = GT;＆＃34; ...

主表单之外的所有fields_for输入。修复表单以将所有用户输入包装在fields_for帮助程序中。

_{关于f.fields_for和简单fields_for的注意事项，非常重要}

<%= form_for @customer, html: { class: 'checkout-attributes profile-form' } do |f| %> # some code here <%= f.fields_for :user, @customer.user do |u| %> <%= u.email_field :email, class: 'form-control' %> <%= u.password_field :password, class: 'form-control' %> <%= u.password_field :password_confirmation, class: 'form-control' %> <% end %> </div> # some code here
