AshCubDB.DataLayer does not support actions
I have created a Resource that I wanted to store with CubDB as the datalayer.
However, I run into the following error message:
AshCubDB.DataLayerdoes not supportupdateactions on this resource.
If I remove the update: :* from the resource’s default action, I get the following error instead:
AshCubDB.DataLayerdoes not supportcreateactions on this resource.
Resource
I created a simple key-value store as an example Resource
defmodule MyApp.Kve do
use Ash.Resource,
domain: MyApp,
data_layer: AshCubDB.DataLayer
attributes do
attribute :key, :string
attribute :value, :string
end
actions do
defaults [:read, :destroy, create: :*, update: :*]
end
cubdb do
directory "/data/cubdb/kv.cubdb"
auto_compact? true
auto_file_sync? true
name :kv_storage
end
end
Turning key into a primary_key does not change anything.

@jimsynz would be able to say more, as this is his package, but it looks like the can? function for the data layer checks the writability of the target directory:
def can?(resource, :create), do: Dir.writable?(resource)
def can?(resource, :update), do: Dir.writable?(resource)
def can?(resource, :upsert), do: Dir.writable?(resource)
def can?(resource, :destroy), do: Dir.writable?(resource)
def can?(resource, :read), do: Dir.readable?(resource)
Ash checks can?/2 at compile time (which it didn’t always do, so that is likely why ash_cubdb does this).
I’ve made a branch on my own fork with this fixed:
{:ash_cubdb, github: "zachdaniel/ash_cub_db", branch: "dont-check-dir"}
You could use this temporarily and then open an issue on the repo for ash_cubdb.
