2個表單，一個頁面，一個對象在Rails中

Question

我的表單是對象驅動的並且使用form_for。我正在尋找2個窗體的1個對象的編輯頁面。更具體地說，我期望讓用戶更改他的密碼以及在同一頁面上更改他的電子郵件。根據提交的表格，驗證等應採取正確的措施。到目前爲止，我無法做到這一點。

我使用Rails 4

問題： 我的驗證特效似乎是無法檢測到郵件的改變/密碼更改（見的觀點隱藏字段），因爲我不能在使用隱藏域PROC。所以我無法檢測到我提交的表單類型。

請告訴我，如果有更多像Rails一樣乾淨利落地完成這項工作，或者如果方法合適，我完全錯過了一些東西。

以下是文件：

控制器/ accounts_controller.rb

def edit 
    set_pagedata('Account Informationen bearbeiten') 
    @account = @current_user 
end 
def update 
    @account = User.find(@current_user.id) 

    if @account.update(account_params) 
    redirect_to account_path 
    else 
    render 'edit' 
    end 
end 

private 

    def account_params 
    params.require(:user).permit(:email, :email_confirmation, :password, :password_confirmation) 
    end 

型號/ user.rb

class User < ActiveRecord::Base 
    has_one :admin 
    has_many :customerships 
    has_many :customers, :through => :customerships 

    validates :salutation, presence: { message: 'Die Anrede wird benötigt!', if: :new_record? } 
    validates :prename, presence: { message: 'Der Vorname wird benötigt!', if: :new_record? } 
    validates :surname, presence: { message: 'Der Nachname wird benötigt!', if: :new_record? } 
    validates :email, 
    presence: { message: 'Die E-Mail Adresse wird benötigt!', if: Proc.new { | c | c.new_record? || c.email.present? } }, 
    uniqueness: { message: 'Diese E-Mail existiert bereits in unserem System!', if: Proc.new { | c | c.new_record? || c.email.present? } } 
    validates :password, 
    confirmation: { message: 'Das Passwort wiederholen Feld muss dem Passwort Feld entsprechen!', if: [:new_record?, :password_change?, '!password.nil?'] }, 
    length: { minimum: 5, maximum: 16, message: 'Das Passwort muss mindestens 5 und darf höchstens 16 Zeichen lang sein!', if: [:new_record?, :password_change?, '!password.nil?'] }, 
    presence: { message: 'Das Passwort wird benötigt!', if: [:new_record?, :password_change?, '!password.nil?'] } 

    has_secure_password :validations => false 

    def admin? 
    Admin.find_by_user_id(self.id) != nil 
    end 

    def password_change? 
    :edit_type == 'password-change' 
    end 
    def mail_change? 
    :edit_type == 'mail-change' 
    end 
end

Answer 1

Rails這樣做的方式是隻使用一種形式：

<%= form_for @account, url: account_path, html: { :class => 'mysd-form' } do |f| %> 
      <ul class="form-container"> 
       <li> 
        <%= f.password_field :password, :value => nil, :class => 'form-control', :placeholder => 'Neues Passwort(leave blank if unchanged)' %> 
       </li> 
       <li> 
        <%= f.password_field :password_confirmation, :value => nil, :class => 'form-control', :placeholder => 'Neues Passwort wiederholen' %> 
       </li> 
<li> 
        <%= f.text_field :email, :value => @account.email, :class => 'form-control', :placeholder => 'Neue E-Mail Adresse' %> 
       </li> 

       <%= f.submit 'Absenden', :class => 'mysd-btn btn-primary' %> 
      </ul> 
     <% end %> 

因此，您使用兩種形式的任何特定原因？
