defaults (@default)

This is the equivalent of Prisma's @default(). It automatically sets default values for fields during create operations.

Basic Usage

const gassma = new Gassma.GassmaClient({
  defaults: {
    Users: {
      role: "USER",
      createdAt: () => new Date(),
    },
  },
});

// Default values are automatically applied during create
gassma.Users.create({
  data: { name: "Alice" },
});
// => { name: "Alice", role: "USER", createdAt: 2026-03-14T... }

Static Values and Functions

You can specify both fixed values and functions as default values.

Type	Example	Behavior
Static value	role: "USER"	Sets the same value every time
Function	createdAt: () => new Date()	Evaluated on each invocation

Applicable Methods

Method	Applied
create	✅
createMany / createManyAndReturn	✅
upsert (create part only)	✅

Behavior with Explicit Values

If a field is explicitly specified (including null), the default value is not applied.

gassma.Users.create({
  data: { name: "Alice", role: "ADMIN" },
});
// => role is "ADMIN" (default value "USER" is not applied)
