List

Section used for the index view.

It inherits its configuration from the base section.

Number of items per page

You can configure the default number of rows rendered per page:

RailsAdmin.config do |config|
  config.default_items_per_page = 50
end

Number of items per page per model

You can also configure it per model:

RailsAdmin.config do |config|
  config.model Team do
    list do
      items_per_page 100
    end
  end
end

Default sorting

By default, rows sorted by the field id in reverse order

You can change default behavior with use two options: sort_by and sort_reverse

RailsAdmin.config do |config|
  config.model Player do
    list do
      sort_by :name
      sort_reverse false
    end
  end
end
