Class EavStrategy
This class provides a way to translate dynamic data by keeping translations in a separate table linked to the original record from another one. Translated fields can be configured to override those in the main table when fetched or put aside into another property for the same entity.
If you wish to override fields, you need to call the locale method in this
behavior for setting the language you want to fetch from the translations table.
If you want to bring all or certain languages for each of the fetched records,
you can use the custom translations finder of TranslateBehavior that is
exposed to the table.

When fetching records, the content for the locale set via this method, and likewise when saving data, it will save the data in that locale.
Note that in case an entity has a _locale property set, that locale
will win over the locale set via this method (and over the globally
configured one for that matter)!

Additionally it creates a i18n HasMany association that will be
used for fetching all translations for each record in the bound table.
translationField() public ¶
translationField(string $field)
Returns a fully aliased field name for translated fields.
If the requested field is configured as a translation field, the content
field with an alias of a corresponding association is returned. Table-aliased
field name is returned for all other fields.
Parameters
