Prisma handles this by implicitly creating an underlying join table, or allowing you to define a custom one, and then exposing a convenient scalar list or object relation on each side. You can create one-to-one, one-to-many, or many-to-many links by combining this directive with the appropriate field types and foreign keys.
Prisma Relations Real World Use Cases
For one-to-many scenarios, you add a field with the type of the related model and mark it with @relation, while Prisma Client will generate a list-like structure to represent the inverse side. The result is a system where the risk of orphaned records or invalid references is minimized without adding manual checks in every handler.
Many-to-Many Relationships Many-to-many relations come into play when records on both sides can associate with multiple records on the other side, like users belonging to multiple groups and groups containing multiple users. You can query deep into these connections using Prisma’s $some, $every, and $none filters, which translate into EXISTS clauses that keep your filtering precise and performant.
