Definition

db. revokePrivilegesFromRole ( rolename, privileges, writeConcern )

Removes the specified privileges from the user-defined role on the database where the method runs. The revokePrivilegesFromRole method has the following syntax:

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

The 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.

The db.revokePrivilegesFromRole() method wraps the revokePrivilegesFromRole 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" }
)
