我使用rails_admin在單擊按鈕時向所有用戶發送電子郵件。該動作被調用兩次而不是一次。rails_admin收集操作執行兩次
的lib/rails_admin_email_everyone.rb：
require 'rails_admin/config/actions'
require 'rails_admin/config/actions/base'
module RailsAdmin
module Config
module Actions
class EmailEveryone < RailsAdmin::Config::Actions::Base
register_instance_option :visible? do
authorized?
end
register_instance_option :link_icon do
'icon-envelope'
end
register_instance_option :collection? do
true
end
register_instance_option :member? do
false
end
register_instance_option :controller do
Proc.new do
@topics_with_owners = Topic.where('user_id IS NOT NULL')
@topics_with_owners.each do |topic|
@reminder = Reminder.new(:topic_id=> topic.id,
:to_user_id => student.id, :from_user_id => current_user.id)
if @reminder.save
TopicMailer.reminder(@reminder.topic).deliver
@reminder.update_attribute(:sent, true)
else
logger.error "Error sending email reminder: "
+ @reminder.errors.full_messages.map {|msg| msg}.join(',')
end
end
flash[:success] = "Reminders successfully sent."
redirect_to back_or_index
end
end
end
end
end
end
配置/初始化/ rails_admin.rb：
require Rails.root.join('lib', 'rails_admin_email_everyone.rb')
RailsAdmin.config do |config|
config.authenticate_with do
redirect_to(main_app.root_path, flash:
{warning: "You must be signed-in as an administrator to access that page"})
unless signed_in? && current_user.admin?
end
module RailsAdmin
module Config
module Actions
class EmailEveryone < RailsAdmin::Config::Actions::Base
RailsAdmin::Config::Actions.register(self)
end
end
end
end
config.actions do
# root actions
dashboard # mandator y
# collection actions
index # mandatory
new
export
history_index
bulk_delete
# member actions
show
edit
delete
history_show
show_in_app
email_everyone do
visible do
bindings[:abstract_model].model.to_s == "Reminder"
end
end
end
end
當我檢查我的日誌我看到它執行了兩次，但略有不同的參數。一個包括pjax。我發現this有關類似問題的pjax超時計算器問題：
