revokeRolesFromRole

Removes the specified inherited roles from a role.

Tip

In mongosh, this command can also be run through the db.revokeRolesFromRole() helper method.

Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.

Syntax

The command has the following syntax:

db.runCommand(
   {
     revokeRolesFromRole: "<role>",
     roles: [
       { role: "<role>", db: "<database>" } | "<role>",
       ...
     ],
     writeConcern: { <write concern> },
     comment: <any>
   }
)

Command Fields

The command has the following fields:

Field
Type
Description
revokeRolesFromRole
string
The role from which to remove inherited roles.
roles
array
The inherited roles to remove.
writeConcern
document

Optional. The level of write concern for the operation. See Write Concern Specification.

comment
any

Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations:

A comment can be any valid BSON type (string, integer, object, array, etc).

In the roles field, you can specify both built-in roles and user-defined roles.

To specify a role that exists in the same database where revokeRolesFromRole runs, you can either specify the role with the name of the role:

"readWrite"

Or you can specify the role with a document, as in:

{ role: "<role>", db: "<database>" }

To specify a role that exists in a different database, specify the role with a document.

Required Access

You must have the revokeRole action on a database to revoke a role on that database.

Example

The purchaseAgents role in the emea database inherits privileges from several other roles, as listed in the roles array:

{
   "_id" : "emea.purchaseAgents",
   "role" : "purchaseAgents",
   "db" : "emea",
   "privileges" : [],
   "roles" : [
      {
         "role" : "readOrdersCollection",
         "db" : "emea"
      },
      {
         "role" : "readAccountsCollection",
         "db" : "emea"
      },
      {
         "role" : "writeOrdersCollection",
         "db" : "emea"
      }
   ]
}

The following revokeRolesFromRole operation on the emea database removes two roles from the purchaseAgents role:

use emea
db.runCommand( { revokeRolesFromRole: "purchaseAgents",
                 roles: [
                          "writeOrdersCollection",
                          "readOrdersCollection"
                        ],
                  writeConcern: { w: "majority" , wtimeout: 5000 }
             } )

The purchaseAgents role now contains just one role:

{
   "_id" : "emea.purchaseAgents",
   "role" : "purchaseAgents",
   "db" : "emea",
   "privileges" : [],
   "roles" : [
      {
         "role" : "readAccountsCollection",
         "db" : "emea"
      }
   ]
}
