resources.resource.define
define nameDefines a function with the corresponding name and arguments. See the code interface guide for more.
Examples
define :get_user_by_id, action: :get_by_id, args: [:id], get?: trueArguments
| Name | Type | Default | Docs |
|---|---|---|---|
name | atom | The name of the function that will be defined |
Options
| Name | Type | Default | Docs |
|---|---|---|---|
action | atom | The name of the action that will be called. Defaults to the same name as the function. | |
args | list(atom | {:optional, atom}) | Map specific arguments to named inputs. Can provide any argument/attributes that the action allows. | |
not_found_error? | boolean | true | If the action or interface is configured with get?: true, this determines whether or not an error is raised or nil is returned. |
require_reference? | boolean | true | For update and destroy actions, require a resource or identifier to be passed in as the first argument. Not relevant for other action types. |
get? | boolean | Expects to only receive a single result from a read action or a bulk update/destroy, and returns a single result instead of a list. Sets require_reference? to false automatically. | |
get_by | atom | list(atom) | Takes a list of fields and adds those fields as arguments, which will then be used to filter. Sets get? to true and require_reference? to false automatically. Adds filters for read, update and destroy actions, replacing the record first argument. | |
get_by_identity | atom | Takes an identity, gets its field list, and performs the same logic as get_by with those fields. Adds filters for read, update and destroy actions, replacing the record first argument. |
