## resources.resource.define
|
|
```elixir
|
|
define name
|
|
```
|
|
|
|
|
|
Defines a function with the corresponding name and arguments. See the [code interface guide](/documentation/topics/resources/code-interfaces.md) for more.

|
|
|
|
|
|
|

### Arguments
|
|
|
|
| Name | Type | Default | Docs |
|
|
|------|------|---------|------|
|
|
| [`name`](#resources-resource-define-name){: #resources-resource-define-name .spark-required} | `atom` | | The name of the function that will be defined |
|
|
### Options
|
|
|
|
| Name | Type | Default | Docs |
|
|
|------|------|---------|------|
|
|
| [`action`](#resources-resource-define-action){: #resources-resource-define-action } | `atom` | | The name of the action that will be called. Defaults to the same name as the function. |
|
|
| [`args`](#resources-resource-define-args){: #resources-resource-define-args } | `list(atom \| {:optional, atom})` | | Map specific arguments to named inputs. Can provide any argument/attributes that the action allows. |
|
|
| [`not_found_error?`](#resources-resource-define-not_found_error?){: #resources-resource-define-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?`](#resources-resource-define-require_reference?){: #resources-resource-define-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?`](#resources-resource-define-get?){: #resources-resource-define-get? } | `boolean` | `false` | 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`](#resources-resource-define-get_by){: #resources-resource-define-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`](#resources-resource-define-get_by_identity){: #resources-resource-define-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. |
