Converts an actor to Ash options list for authorization.
|
|
Returns empty list if actor is nil.
|
|
|
|
This helper ensures consistent actor handling across all Ash operations
|
|
in the application, whether called from LiveViews, changes, validations,
|
|
or other contexts.
|
|
|
|
## Examples
|
|
|
|
opts = ash_actor_opts(actor)
|
|
Ash.read(query, opts)
|
|
|
|
opts = ash_actor_opts(nil)

Returns the query unchanged if `exclude_id` is nil; otherwise adds a filter `id != ^exclude_id`.

Used in uniqueness validations that must exclude the current record (e.g. name uniqueness
|
|
on update, duplicate association checks). Call with the record's primary key to exclude it
|
|
from the result set.
