Roles

Copied!
( [database] )

Description

The Roles function, when executed with Paginate, returns an Array of References for user-defined roles in the specified child database. If a child database is not specified, the role references returned all belong to the current database.

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

Parameters

Parameter Type Definition and requirements

Returns

An Set Reference for the available user-defined roles in the specified child database (or the current database if database is not specified).

  1. The following query lists any user-defined roles (up to the pagination limit) in the current database:

    Copied!
    client.query(
  q.(q.())
)
.then((result) => console.log(result))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
    { data: [ ("employees") ] }
    Query metrics:

    •    bytesIn:   27

    •   bytesOut:   88

    • computeOps:    1

    •    readOps:    8

    •   writeOps:    0

    •  readBytes:  250

    • writeBytes:    0

    •  queryTime: 15ms

    •    retries:    0

  2. The following query lists the References for any user-defined roles (up to the pagination limit) in a child database named "child_db":

    Copied!
    client.query(
  q.(q.(q.('child_db')))
)
.then((result) => console.log(result))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
    { data: [] }
    Query metrics:

    •    bytesIn:   46

    •   bytesOut:   24

    • computeOps:    1

    •    readOps:    8

    •   writeOps:    0

    •  readBytes:  363
