我会这样做：确保将其粘贴到 app / admin / admin_user.rb 文件。我不会直接添加控制器方法，而是会使用 member_action dsl指令添加逻辑。

I would do it this way: make sure to paste this in the app/admin/admin_user.rb file. I would not add controller methods directly but would use the member_action dsl directive to add logic. Good luck!

action_item :reset_password, :only => :edit do
 link_to 'Reset password',  do_password_reset_admin_admin_user_path(resource), :method => :post
end

member_action :do_password_reset, :method => :post do
  flash.notice = "A mail containing password reset instructions has been sent to: #{resource.email}"
  resource.send_reset_password_instructions
  redirect_to edit_admin_admin_user_path(resource) and return
end
