View Source Ordering

You can configure the ordering of the resource index page. By default, the resources are ordered by the id field in ascending order.

Configuration

To configure the ordering of the resource index page, use the init_order option in your resource configuration file. This option accepts either a map or a function that returns a map.

The map must contain the following keys:

  • :by - The field to order by (atom)
  • :direction - The order direction (:asc for ascending or :desc for descending)

Using a Map

You can directly specify the ordering with a map:

# in your resource configuration file (live resource)
use Backpex.LiveResource,
  # ...other options
  init_order: %{by: :inserted_at, direction: :desc}

This configuration orders resources by the inserted_at field in descending order.

Using a Function 

# in your resource configuration file (live resource)
use Backpex.LiveResource,
  # ...other options
  init_order: &__MODULE__.init_order/1

def init_order(_assigns) do
  %{by: :username, direction: :asc}
end

The function must:

  • Take one argument (assigns)
  • Return a map with :by and :direction keys

This approach allows you to determine the ordering based on runtime conditions or user-specific data in assigns.

Important

Note that it is not possible to use an anonymous function for init_order configuration. You must refer to a public function defined within a module.
