Class

Copied!
( name, [database] )

Description

This function is deprecated as of Fauna 2.7.0. Use Collection instead.

A Class was renamed to a Collection in Fauna 2.7.0. This function continues to exist for compatibility with older drivers.

The Class function returns a valid Reference for the specified class (now, collection) name, in the specified child database. If a child database is not specified, the returned class (now, collection) reference belongs to the current database.

When a child database is specified, an admin key must be used to call Class (server or client keys, or ABAC tokens, cannot be used to access a child database).

Parameters
