请参阅没有设计的相同应用程序示例：链接

我试过 git clone 它，当导入 excel 文件成功时。

我正在尝试设计注册从 excel 文件中获取电子邮件和密码，

这是imports_controller.rb

class ImportsController < Devise::RegistrationsController
  before_filter :resource_name

def resource_name
  :user
end

def import
end

def create  
  get_file = params[:excelfile]
    file = ImportUploader.new
    file.store!(get_file)
    book = Spreadsheet.open "#{file.store_path}"
    sheet = book.worksheet 0
    @user = []
    sheet.each 1 do |row|
      u = User.new
      u.email = row[0]
      u.password = row[1]
      u.save
      @user << u
    end
        redirect_to root_path
end

import.html.erb

<%= form_tag import_path, multipart: true do %>
  <%= file_field_tag :excelfile %>
  <%= submit_tag "Import" %>
<% end %>

当我尝试导入 excel 文件时

我很困惑，因为我的应用程序没有错误，我不知道错误的位置以便回滚。

任何的想法？

谢谢。

解决。我正在使用手动创建用户 https://github.com/plataformatec/devise/wiki/How-To:-Manage-users-through-a-CRUD-interface

def create  
  get_file = params[:excelfile]
    file = ImportUploader.new
    file.store!(get_file)
    book = Spreadsheet.open "#{file.store_path}"
    sheet1 = book.worksheet 0
    sheet1.each 1 do |row|
      email = row[0]
      temp_password = row[1]
      Pelajar.create(:email => email, :password => temp_password, :password_confirmation => temp_password)
    end
        redirect_to root_path
end
