# DSL: Ash.Domain.Dsl
## domain
General domain configuration
### Examples
```
domain do
description """
Resources related to the flux capacitor.
"""
end
```
### Options
| Name | Type | Default | Docs |
|------|------|---------|------|
| [`description`](#domain-description){: #domain-description } | `String.t` | | A description for the domain. |
## resources
List the resources of this domain
### Nested DSLs
* [resource](#resources-resource)
* define
* define_calculation
### Examples
```
resources do
resource MyApp.Tweet
resource MyApp.Comment
end
```
### Options
| Name | Type | Default | Docs |
|------|------|---------|------|
| [`allow`](#resources-allow){: #resources-allow } | `mfa` | | Support a dynamic resource list by providing a callback that checks whether or not the resource should be allowed. |
| [`allow_unregistered?`](#resources-allow_unregistered?){: #resources-allow_unregistered? } | `boolean` | `false` | Whether the domain will support only registered entries or not. |
## resources.resource
```elixir
resource resource
```
A resource present in the domain
### Nested DSLs
* [define](#resources-resource-define)
* [define_calculation](#resources-resource-define_calculation)
### Examples
```
resource Foo
```
### Arguments
| Name | Type | Default | Docs |
|------|------|---------|------|
| [`resource`](#resources-resource-resource){: #resources-resource-resource .spark-required} | `module` | | |
## 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.
### Examples
```
define :get_user_by_id, action: :get_by_id, args: [:id], get?: true
```
### 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. |
### Introspection
Target: `Ash.Resource.Interface`
## resources.resource.define_calculation
```elixir
define_calculation name
```
Defines a function with the corresponding name and arguments, that evaluates a calculation. Use `:_record` to take an instance of a record. See the [code interface guide](/documentation/topics/resources/code-interfaces.md) for more.
### Examples
```
define_calculation :referral_link, User, args: [:id]
```
```
define_calculation :referral_link, User, args: [{:arg, :id}, {:ref, :id}]
```
### Arguments
| Name | Type | Default | Docs |
|------|------|---------|------|
| [`name`](#resources-resource-define_calculation-name){: #resources-resource-define_calculation-name .spark-required} | `atom` | | The name of the function that will be defined |
### Options
| Name | Type | Default | Docs |
|------|------|---------|------|
| [`calculation`](#resources-resource-define_calculation-calculation){: #resources-resource-define_calculation-calculation } | `atom` | | The name of the calculation that will be evaluated. Defaults to the same name as the function. |
| [`args`](#resources-resource-define_calculation-args){: #resources-resource-define_calculation-args } | `any` | `[]` | Supply field or argument values referenced by the calculation, in the form of :name, `{:arg, :name}` and/or `{:ref, :name}`. See the [code interface guide](/documentation/topics/resources/code-interfaces.md) for more. |
