box.schema.user.grant() | Tarantool


box.schema.user.grant(user-name, privileges, object-type, object-name[, {options}])
box.schema.user.grant(user-name, privileges, 'universe'[, nil, {options}])
box.schema.user.grant(user-name, role-name[, nil, nil, {options}])

Grant privileges to a user or to another role.

  • user-name (string) – the name of the user.
  • privileges (string) – ‘read’ or ‘write’ or ‘execute’ or ‘create’ or ‘alter’ or ‘drop’ or a combination.
  • object-type (string) – ‘space’ or ‘function’ or ‘sequence’ or ‘role’.
  • object-name (string) – name of object to grant permissions for.
  • role-name (string) – name of role to grant to user.
  • options (table) – grantor, if_not_exists.

If 'function','object-name' is specified, then a _func tuple with that object-name must exist.

Variation: instead of object-type, object-name say ‘universe’ which means ‘all object-types and all objects’. In this case, object name is omitted.

Variation: instead of privilege, object-type, object-name say role-name (see section Roles).

Variation: instead of box.schema.user.grant('user-name','usage,session','universe',nil, {if_not_exists=true}) say box.schema.user.enable('user-name').

The possible options are:

  • grantor = grantor_name_or_id – string or number, for custom grantor,
  • if_not_exists = true|false (default = false) - boolean; true means there should be no error if the user already has the privilege.
