ruby-on-rails - Load timeout in Rails's Active Admin

Question

I'm using ActiveAdmin (https://github.com/gregbell/active_admin) for Rails, and am trying to load the index view of my User model. Here's the code in my app/admin/users.rb file:

ActiveAdmin.register User do
    config.per_page = 10

    index :pagination_total => false do
    end
end

I have pagination enabled, but it looks like it's still trying to load all of the users, resulting in a timeout. How do I get it to load only a few (e.g. 10) users at a time?

您可以尝试提高网页性能的几件事：

1. 尝试从您可能拥有的任何范围内禁用计数：

   scope :active, show_count: false
   

2. 尝试禁用不需要的过滤器

   config.filters = false #or simply specify the ones you do need
   

3. 通过预先加载任何关联模型来避免 n+1 查询

   controller do
     def scoped_collection
       resource_class.includes(:brownies)
     end
   end
   

希望这可以帮助。
