使用devise和active admin处理一些继承的代码。
我有一个表单来创建一个admin_user（电子邮件，密码，密码确认）点击提交后，浏览器会在向我显示504之前挂起。用户已创建并在数据库中。
这个问题出乎意料。我所做的少数提交没有触及项目的这一部分。
以下是创建管理员用户表单的代码。在此之后会发生什么我仍然不清楚：
ActiveAdmin.register AdminUser do
menu :parent => "Sys Admin", :priority => 2
index do
column :email
column :current_sign_in_at
column :last_sign_in_at
column :sign_in_count
default_actions
end
filter :email
form do |f|
f.inputs "Admin Details" do
f.input :email
f.input :password
f.input :password_confirmation
end
f.buttons
end
controller do
#https://coderwall.com/p/xfrujq
def update_resource(object, attributes)
update_method = attributes.first[:password].present? ? :update_attributes : :update_without_password
object.send(update_method, *attributes)
end
end
end
