FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Role

This reference topic applies to FQL v4. Go to this page for the latest FQL v10 reference topics.

 
Role( name, [database] )
role( name, [database] )
Role( name )
ScopedRole( name, database )
Role( name, [database] )
Role( name, [database] )
Role( name, [database] )

Description

The Role function returns a Reference for the specified user-defined role’s name in the specified child database. If a child database is not specified, the role returned belongs to the current database.

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

Also, Go does not support optional function parameters, nor function overloading. To specify a child database using the Go driver, call the ScopedRole function instead of Role.

Parameters

Examples

  1. The following query gets a Reference to the user-defined role named "admin" in the current database:

    client.query(
  q.Role('admin')
)
.then((result) => console.log(result))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
    Role("admin")
    result = client.query(
  q.role("admin")
)
print(result)
    Ref(id=admin, collection=Ref(id=roles))
    result, err := client.Query(
	f.Role("admin"))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
    {admin 0xc00016e090 0xc00016e090 <nil>}
    try
{
    Value result = await client.Query(
        Role("admin")
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
    RefV(id = "admin", collection = RefV(id = "roles"))
    System.out.println(
    client.query(
        Role("admin")
    ).get());
    ref(id = "admin", collection = ref(id = "roles"))
    Role('admin')
    Role("admin")

  2. The following query gets a Reference to the user-defined role named "admin" in a child database named "child_db":

    client.query(
  q.Role('admin', q.Database('child_db'))
)
.then((result) => console.log(result))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
    Role("admin", Database("child_db"))
    result = client.query(
  q.role("admin", q.database("child_db"))
)
print(result)
    Ref(id=admin, collection=Ref(id=roles), database=Ref(id=child_db, collection=Ref(id=databases)))
    result, err := client.Query(
	f.ScopedRole("admin", f.Database("child_db")))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
    {admin 0xc00011e300 0xc00011e300 0xc00011e360}
    try
{
    Value result = await client.Query(
        Role("admin", Database("child_db"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
    RefV(id = "admin", collection = RefV(id = "roles"), database = RefV(id = "child_db", collection = RefV(id = "databases")))
    System.out.println(
    client.query(
        Role("admin", Database("child_db"))
    ).get());
    ref(id = "admin", collection = ref(id = "roles"), database = ref(id = "child_db", collection = ref(id = "databases")))
    Role('admin', Database('child_db'))
    Role("admin", Database("child_db"))
