Question

在此处输入代码我使用MD5加密我的密码，但是，在编辑用户配置文件时，用户往往不会编辑他们的密码。所以保持密码不变。但在我的实现中，密码总是更新。

    Here is the code in my account model.rb
    class Admin::Account < ActiveRecord::Base
      require 'digest/md5'
      acts_as_reader
      before_save :encrypt_password

      def encrypt_password
        self.password = Digest::MD5.hexdigest(password)
      end
    end

// 修改 class Admin :: AccountsController＆lt; ApplicationController中

  before_filter :check_login, only: [:new, :index, :edit, :show, :destroy]
  before_action :set_admin_locale, only: [:new, :index, :edit, :show, :destroy,:create,:update]
  layout 'admin_layout'
  # before_action :set_admin_account, only: [:show, :edit, :update, :destroy]

  # GET /admin/accounts
  # GET /admin/accounts.json

  def update_user
    @admin_account = Admin::Account.find(params[:id])
    respond_to do |format|
    if @admin_account.update(admin_account_params)
      @success = true
      session[:nationality] = @admin_account.nationality
      format.js
    else
      @success = false
      format.js
    end
    end
  end

  private
  # Use callbacks to share common setup or constraints between actions.
  def set_admin_account
    @admin_account = Admin::Account.find(params[:id])
  end

  # Never trust parameters from the scary internet, only allow the white list through.
  def admin_account_params
    gender = "M"
    if params[:admin_account][:gender] == "Female"
      gender = "F"
    end
    if params[:admin_account][:password] != ""
      params.require(:admin_account).permit(:email, :password, :name, :account_type, :student_number, :nationality,:photo,:date_of_birth).merge(:gender => gender)
    else
      params.require(:admin_account).permit(:email, :name, :account_type, :student_number, :nationality,:photo,:date_of_birth).merge(:gender => gender)
    end
  end

  def register_account
    gender = "M"

    if params[:admin_account][:gender] == "Female"
      gender = "F"
    end

    if params[:admin_account][:student_number].present?
      params.require(:admin_account).permit(:email, :password, :name, :password_confirmation, :student_number,:nationality,:photo,:date_of_birth).merge(:account_type => 'Student', :gender => gender)
    else
      params.require(:admin_account).permit(:gender,:email, :password, :name, :password_confirmation,:nationality,:photo,:date_of_birth).merge(:account_type => 'Not Student',:gender => gender)
    end
  end

end

在encrypt_password方法中添加条件

def encrypt_password
   if password.present? and !password.blank?
     self.password = Digest::MD5.hexdigest(password)
   end
end

如果密码不为空，如何加密密码
