Options

Name	Type	Default	Docs
`type`{: #json_api-type }	`String.t`		The resource identifier type of this resource in JSON:API
`always_include_linkage`{: #json_api-always_include_linkage }	`list(atom)`	`[]`	A list of relationships that should always have their linkage included in the resource
`includes`{: #json_api-includes }	`any \| list(any)`	`[]`	A keyword list of all paths that are includable from this resource
`paginated_includes`{: #json_api-paginated_includes }	`list(atom \| list(atom))`	`[]`	A list of relationship paths that can be paginated when included via the `included_page` query parameter. Each entry can be either an atom (for top-level relationships) or a list of atoms (for nested paths).
`include_nil_values?`{: #json_api-include_nil_values? }	`any`		Whether or not to include properties for values that are nil in the JSON output
`default_fields`{: #json_api-default_fields }	`list(atom)`		The fields to include in the object if the `fields` query parameter does not specify. Defaults to all public
`derive_sort?`{: #json_api-derive_sort? }	`boolean`	`true`	Whether or not to derive a sort parameter based on the sortable fields of the resource
`derive_filter?`{: #json_api-derive_filter? }	`boolean`	`true`	Whether or not to derive a filter parameter based on the sortable fields of the resource
`relationship_meta_in`{: #json_api-relationship_meta_in }	`keyword`	`[]`	Configures how incoming JSON:API `meta` keys on relationship resource identifiers map to join resource attributes for many_to_many relationship writes. Use together with `relationship_meta_out` for reads. Each relationship you want to support must declare both mappings explicitly.
`relationship_meta_out`{: #json_api-relationship_meta_out }	`keyword`	`[]`	Configures how join resource attributes map to outgoing JSON:API `meta` keys on relationship resource identifiers for many_to_many relationship reads. Use together with `relationship_meta_in` for writes. Each relationship you want to support must declare both mappings explicitly.
`field_names`{: #json_api-field_names }	`:camelize \| :dasherize \| keyword \| (any -> any)`		Renames fields (attributes, relationships, calculations, and aggregates) in the JSON:API output and input. Can be one of the atoms `:camelize` or `:dasherize` for automatic conversion, a keyword list of `[ash_name: :json_api_name]` mappings, or a 1-arity function that receives an atom field name and returns the desired JSON:API name (atom or string). `elixir field_names :camelize # first_name → firstName field_names :dasherize # first_name → first-name` Or with a keyword list: `elixir field_names [ first_name: :firstName, last_name: :lastName ]` Or with a function for custom logic: `elixir field_names fn name -> camelized = name \|> to_string() \|> Macro.camelize() {first, rest} = String.split_at(camelized, 1) String.downcase(first) <> rest end` Names are applied consistently across serialization, request parsing, sort/filter parameters, field selection, error source pointers, relationship keys, and schema generation.
`argument_names`{: #json_api-argument_names }	`:camelize \| :dasherize \| keyword \| (any, any -> any)`		Renames action arguments in the JSON:API request body and schema. Can be one of the atoms `:camelize` or `:dasherize` for automatic conversion, a nested keyword list of `[action_name: [ash_name: :json_api_name]]` mappings, or a 2-arity function that receives `(action_name, argument_name)` atoms and returns the desired JSON:API name (atom or string). `elixir argument_names :camelize # publish_at → publishAt argument_names :dasherize # publish_at → publish-at` Or with a keyword list: `elixir argument_names [ create: [my_arg: :myArg], update: [my_arg: :myArg] ]` Or with a function: `elixir argument_names fn _action, name -> camelized = name \|> to_string() \|> Macro.camelize() {first, rest} = String.split_at(camelized, 1) String.downcase(first) <> rest end`
`calculation_argument_names`{: #json_api-calculation_argument_names }	`:camelize \| :dasherize \| keyword \| (any, any -> any)`		Renames calculation arguments in the JSON:API request and schema. Works the same way as `argument_names` but applies to calculation arguments instead of action arguments. The 2-arity function receives `(calculation_name, argument_name)`. Can be one of the atoms `:camelize` or `:dasherize` for automatic conversion, a nested keyword list of `[calc_name: [ash_name: :json_api_name]]` mappings, or a 2-arity function that receives `(calculation_name, argument_name)` atoms and returns the desired JSON:API name (atom or string). `elixir calculation_argument_names :camelize # publish_at → publishAt calculation_argument_names :dasherize # publish_at → publish-at` Or with a keyword list: `elixir calculation_argument_names [ full_name: [separator: :sep] ]` Or with a function: `elixir calculation_argument_names fn _calc, name -> camelized = name \|> to_string() \|> Macro.camelize() {first, rest} = String.split_at(camelized, 1) String.downcase(first) <> rest end`

`path_param_is_composite_key`{: #json_api-routes-post_to_relationship-path_param_is_composite_key }	`atom`		The path parameter that should be parsed as a composite primary key. When specified (e.g., :id), the parameter will be split using the resource's primary key delimiter and mapped to individual primary key fields. This is required for resources with composite primary keys to work correctly with GET, PATCH, and DELETE operations. See the composite primary keys documentation for more details.
