db.revokePrivilegesFromRole(rolename, privileges, writeConcern)

Removes the specified privileges from the user-defined role on the database where the method runs.

Important

mongo Shell Method

This page documents a mongo method. This is not the documentation for database commands or language-specific drivers, such as Node.js. To use the database command, see the revokePrivilegesFromRole command.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

The db.revokePrivilegesFromRole() method has the following syntax:

db.revokePrivilegesFromRole(
    "<rolename>",
    [
        { resource: { <resource> }, actions: [ "<action>", ... ] },
        ...
    ],
    { <writeConcern> }
)

The db.revokePrivilegesFromRole() method takes the following arguments:

Parameter	Type	Description
`rolename`	string	The name of the user-defined role from which to revoke privileges.
`privileges`	array	An array of privileges to remove from the role. See `privileges` for more information on the format of the privileges.
`writeConcern`	document	Optional. The level of write concern for the modification. The `writeConcern` document takes the same fields as the `getLastError` command.

Behavior

Replica set

If run on a replica set, db.revokePrivilegesFromRole() is executed using "majority" write concern by default.

Scope

To revoke a privilege, the resource document pattern must match exactly the resource field of that privilege. The actions field can be a subset or match exactly.

For example, given the role accountRole in the products database with the following privilege that specifies the products database as the resource:

{
  "resource" : {
      "db" : "products",
      "collection" : ""
  },
  "actions" : [
      "find",
      "update"
  ]
}

You cannot revoke find and/or update from just one collection in the products database. The following operations result in no change to the role:

use products
db.revokePrivilegesFromRole(
   "accountRole",
   [
     {
       resource : {
          db : "products",
          collection : "gadgets"
       },
       actions : [
          "find",
          "update"
       ]
     }
   ]
)
db.revokePrivilegesFromRole(
   "accountRole",
   [
     {
       resource : {
          db : "products",
          collection : "gadgets"
       },
       actions : [
          "find"
       ]
     }
   ]
)

To revoke the "find" and/or the "update" action from the role accountRole, you must match the resource document exactly. For example, the following operation revokes just the "find" action from the existing privilege.

use products
db.revokePrivilegesFromRole(
   "accountRole",
   [
     {
       resource : {
          db : "products",
          collection : ""
       },
       actions : [
          "find"
       ]
     }
   ]
)

Required Access

You must have the revokeRole action on the database a privilege targets in order to revoke that privilege. If the privilege targets multiple databases or the cluster resource, you must have the revokeRole action on the admin database.

Example

The following operation removes multiple privileges from the associates role:

db.revokePrivilegesFromRole(
   "associate",
   [
     {
       resource: { db: "products", collection: "" },
       actions: [ "createCollection", "createIndex", "find" ]
     },
     {
       resource: { db: "products", collection: "orders" },
       actions: [ "insert" ]
     }
   ],
   { w: "majority" }
)
