User Groups

To add users to groups and grant groups access to an object using OpenFGA.

When to use

Relationship tuples can specify that an entire group has a relation to an object, which is helpful when you want to encompass a set of users with the same relation to an object. For example:

Grant viewer access to a group of engineers in roadmap.doc
Create a block_list of members who can't access a document
Sharing a document with a team
Granting viewer access to a photo to followers only
Making a file viewable for all users within an organization
Restricting access from or to users in a certain locale

Before you start

Familiarize yourself with the OpenFGA Concepts.

Assume you have the following authorization model.
: you have an object called document that users can relate to as an editor.

DSL
JSON

model
  schema 1.1

type user

type document
  relations
    define editor: [user]

{
  "schema_version": "1.1",
  "type_definitions": [
    {
      "type": "user"
    },
    {
      "type": "document",
      "relations": {
        "editor": {
          "this": {}
        }
      },
      "metadata": {
        "relations": {
          "editor": {
            "directly_related_user_types": [
              {
                "type": "user"
              }
            ]
          }
        }
      }
    }
  ]
}

In addition, you will need to know the following:

Direct Access

You need to know how to create an authorization model and a relationship tuple to grant a user access to an object. To learn more, see direct access.

OpenFGA Concepts

A Type: a class of objects that have similar characteristics.
A User: an entity in the system that can be related to an object.
A Relation: a string defined in the type definition of an authorization model that defines the possibility of a relationship between an object of the same type as the type definition and a user in the system.
An Object: represents an entity in the system. Users' relationships to it can be defined with relationship tuples and the authorization model.
A Relationship Tuple: a grouping consisting of a user, a relation and an object stored in OpenFGA.

Step By Step

There are possible use cases where a group of users have a certain role on or permission to an object. For example, members of a certain team could have an editor relation to a certain document.

To represent this in OpenFGA:

Introduce the concept of a team to the authorization model. →
Add users as members to the team. →
Assign the team members a relation to an object. →
Check an individual member's access to the object. →

01. Introduce the concept of a team to the authorization model

First, define the object team in your authorization model. In this use case, a team can have members, so you make the following changes to the authorization model:

DSL
JSON

model
  schema 1.1

type user

type document
  relations
    define editor: [team#member]

type team
  relations
    define member: [user]

{
  "schema_version": "1.1",
  "type_definitions": [
    {
      "type": "user"
    },
    {
      "type": "document",
      "relations": {
        "editor": {
          "this": {}
        }
      },
      "metadata": {
        "relations": {
          "editor": {
            "directly_related_user_types": [
              {
                "type": "team",
                "relation": "member"
              }
            ]
          }
        }
      }
    },
    {
      "type": "team",
      "relations": {
        "member": {
          "this": {}
        }
      },
      "metadata": {
        "relations": {
          "member": {
            "directly_related_user_types": [
              {
                "type": "user"
              }
            ]
          }
        }
      }
    }
  ]
}

02. Add users as members to the team

You can now assign users as members of teams. Create a new relationship tuple that states user:alice is a member of team:writers.

03. Assign the team members a relation to an object

To represent groups, use the type:object_id#relation format, which represents the set of users related to the type:object_id as a certain relation. For example, team:writers#members represents the set of users related to the team:writers object as members.

In order to assign members of a team a relation to a document, create the following relationship tuple stating that members of team:writers are editors of document:meeting_notes.doc.

Reply: true

The chain of resolution is:

alice is member of team:writers
members of team:writers are editors of document:meeting_notes
therefore, alice is editor of document:meeting_notes

caution

Note: When creating relationship tuples for OpenFGA, use unique ids for each object and user in your application domain. This example uses first names and simple ids as a suggested example.
