Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:5

Type Parameters

T

T extends object

Properties

attachTo?

optional attachTo?: (p) => SchemaPath<unknown>

Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:11

Optional selector to determine which field should receive the validation error. If omitted, the error is attached to all participating fields.

Parameters

p

SchemaPathTree<T>

Returns

SchemaPath<unknown>

exclude?

optional exclude?: (p) => SchemaPath<unknown>[]

Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:40

Optional list of fields to exclude from the “at least one” check.

This is useful in recursive mode to skip structural or metadata fields (like a discriminator field).

Parameters

p

SchemaPathTree<T>

Returns

SchemaPath<unknown>

isFilled?

optional isFilled?: (value) => boolean

Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:17

Optional function to define what should count as “filled”. By default, a value is considered filled if it is neither null nor an empty string ('').

Parameters

value

unknown

Returns

boolean

message?

optional message?: string

Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:23

Optional custom validation error message.

recursive?

optional recursive?: boolean

Defined in: projects/ngx-signal-schema/src/lib/validators/required-at-least-one.ts:33

Optional flag to enable recursive validation of nested objects.

If enabled, the validation will traverse nested objects and validate their properties as well. Otherwise, nested objects themselves are ignored and only direct leaf fields participate.

Defaults to true if no selectors are provided, and false otherwise.
