soft delete - identity issue
i have a resource, for which soft delete is on, the resource has a field: :deleted_at.
If I do not add this field to the identity, on creation the data is validated to be unique, but if I (soft) delete a record, than I can not create another one with the same unique fields.
If I add the field to the identity, on creation the data is not validated correctly, since it includes the deleted_at null field.
I created a template project back then without ash for the soft delete and historization, and someone told me to add the nulls_distinct: false option, and it will solve the problem.
I also found the same config option in ash, and added nils_distinct?: false.
Now it looks good for checking uniqueness upon creation, and I can also delete a resource, but only once.
Somehow the deleted_at uniqueness should be - according to my understanding - unique on the timestamp basis, but it still gives me this error upon save:
Form Error: [
%Ash.Error.Changes.InvalidAttribute{
field: :deleted_at,
message: "Supplier price already exists for this configuration",
private_vars: [
constraint: :unique,
constraint_name: "supplier_prices_unique_supplier_price_index"
],
value: nil,
splode: Ash.Error,
bread_crumbs: [],
vars: [],
path: [],
stacktrace: #splode.Stacktrace<>,
class: :invalid
}
