Check out v4 of the Fauna CLI

v4 of the Fauna CLI is now in beta.

The new version introduces enhancements to the developer experience, including an improved authentication workflow. To get started, check out the CLI v4 quick start.

Role.create()

Learn: Roles

We recommend you use FSL to create and update user-defined roles. See FSL role schema.

Create a user-defined role.

Signature

Role.create(data: { name: String, privileges: Any | Null, membership: Any | Null, data: { *: Any } | Null }) => Role

Description

Creates a user-defined role with the provided document fields. Fauna stores user-defined roles as documents in the Role system collection.

Role documents are FQL versions of a database’s FSL role schema. See Roles.

Staged schema

If a database has staged schema, this method adds a role to the staged schema, not the active schema.

If the database has no staged schema, using this method is equivalent to making an unstaged schema change. Changes are applied immediately to the database’s active schema.

Avoid concurrent schema changes

Concurrent unstaged schema changes can cause contended transactions, even if the changes affect different resources. This includes unstaged changes made using:

A schema change triggers a transaction that validates the entire database schema. To avoid errors, do one of the following instead:
