Multiple roles for a user

I have a scenario where a user can have multiple roles at the same time. For example a user can be editor and translator. What is the recommended approach for this situation?

Hi @Anas Badran You can use a many-to-many relationship between the User and Role models 
model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  roles Role[]
}

model Role {
  id    Int    @id @default(autoincrement())
  name  String @unique
  users User[]
}
model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  roles Role[]
}

model Role {
  id    Int    @id @default(autoincrement())
  name  String @unique
  users User[]
}

Is this approach better than putting the roles in an array jsonb Based on database optimization and performance POV.

The implicit many-to-many approach is generally better for performance, scalability, and data integrity due to indexing and efficient querying, while JSONB arrays may suit simpler use cases.
