ruby-on-rails – 设计可邀请的批量邀请 – Ruby on rails

Provide a text area that accepts a comma-separated email list. Define
a new action that sends an invitation to each email in this list.

让我们假设这个例子的用户模型和用户控制器.

为batch_invite操作定义路由.

resources :users do
  collection do
    post 'batch_invite'
  end
end

在users_controller中定义batch_invite操作

def batch_invite
  #Validate the user_emails field isn't blank and emails are valid
  params[:user_emails].split(",").each do |email|
    User.invite!(:email => email)
  end
  #redirect_to appropriate path
end

在textarea中接受以逗号分隔的电子邮件列表的表单.

<%= form_tag batch_invite_users_path,:method => :post do %>
  <%= label_tag "Email ids of people you'd like to invite." %>
  <%= text_area_tag :user_emails %>
  <%= submit_tag "Invite!" %>
<% end %>

几个笔记：

>如果你喜欢你的控制器瘦,你可以将逻辑移动到模型,例如,在你的用户模型中创建一个send_batch_invitations方法,并从用户控制器传递params [：user_emails]作为参数.
>由于发送邀请的方法可能需要足够的时间才能完成,我建议您将此任务分配给后台作业处理器,例如delayed_job或resque.
有railscasts演示了这两个后台作业处理器的用法.
