Rails 3.2 Omniauth 设计 - 添加密码 - 跳过当前密码

Question

我正在使用 Omniauth 来允许用户通过 Facebook、Twitter 和 Google 登录（并创建一个帐户）。

但是，如果用户决定不再使用这些服务，而是继续使用他们的帐户，他们将需要添加密码。

如何让用户在不输入current password 的情况下为其帐户添加密码？*

当我让用户转到edit_user_registration_path(@user) 时，他们会看到下面的表格：

= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put, name: 'validation'}) do |f|
  = devise_error_messages!

  = f.label :email, class: 'block'
  = f.email_field :email, class: 'large'
  %span.infobar Keep this here unless you'd like to change your email

  = f.label :password, class: 'block'
  = f.password_field :password, class: 'large'
  %span.infobar Leave blank if you don't want to change it

  = f.label :password_confirmation, class: 'block'
  = f.password_field :password_confirmation, class: 'large'

  - if @user.password_required?
    = f.label :current_password, class: 'block'
    = f.password_field :current_password, class: 'large'
    %span.infobar We need your current password to confirm changes

  = f.submit "Update"

user.rb

def password_required?
  (authentications.empty? || !password.blank?) && super
end

如您所见，我有它，如果@user.password_required?，则显示当前密码字段。即使在尝试为帐户创建新密码时未显示此字段，表单也不会正确验证，因为需要当前密码。

我只是重写了 RegistrationsController#update 方法：

class RegistrationsController < Devise::RegistrationsController
  def update
    # Override Devise to use update_attributes instead of update_with_password.
    # This is the only change we make.
    if resource.update_attributes(params[resource_name])
      set_flash_message :notice, :updated
      # Line below required if using Devise >= 1.2.0
      sign_in resource_name, resource, :bypass => true
      redirect_to after_update_path_for(resource)
    else
      clean_up_passwords(resource)
      render_with_scope :edit
    end
  end
end
