Compare nullable fields in filters
I have this filter in my action:
|> Ash.Query.filter(organization_id == ^actor.organization_id)
The issue with it is that organization_id can be null, so when that happen, I will get this warning:
warning: Comparing values with `nil` will always return `false`. Use `is_nil/1` instead. In: `organization_id == nil`

How can I rewrite that so I will stop getting this warning?

How about something like this?
|> then(fn query ->
if is_nil(actor.organization_id) do
Ash.Query.filter(query, is_nil(organization_id))
else
Ash.Query.filter(query, organization_id == ^actor.organization_id)
end
end)
