Validation

When you configure a static schema in Kosame, it automatically validates data during both write and read operations.

static schema

Kosame does not have its own schema definition DSL, so you'll need to create one yourself. If you write a static schema (drizzle-zod's createInsertSchema(table)) in the Model, it will work.

import { createInsertSchema } from "drizzle-zod";

export class User extends Model {
  static table = usersTable;
  static schema = createInsertSchema(usersTable, {
    name: (schema) => schema.min(1),
  });
  declare id: number;
  declare name: string;
}

Validation Timing

Validation runs during write and read operations. Validation is performed during add()/update()/save() calls, during hydration in find()/reload(), and when retrieving relationships via include.

In Case of Failure

If validation fails, an exception is thrown, and database operations and hydration are halted.
