Instance Method Details

#translate_metadata_field_option(field_name, value) ⇒ Object

Takes a metadata field (machine name) and option (value) and returns a translated string according to the language of the current page, suitable for displaying to the public.

By contrast to TranslateMetadataField above, this is for translating the options of multiple-choice schema fields. But similar to TranslateMetadataField, this looks for a “translation_key” property on the option in the schema.

Temporary backwards compatibility: If the check fails, it falls back to whatever is in a “name” property in the schema.

Parameters

field_name : string

The machine name of a metadata field.

value : string

The 'value' of the option to use.
