重要提示

本文档适用于 [email protected] 及更高版本

您还必须安装 Drizzle ORM v0.36.0 或更高版本以及 Valibot v1.0.0-beta.7 或更高版本。

选择模式

定义从数据库查询的数据的形状 - 可用于验证 API 响应。

import { pgTable, text, integer } from 'drizzle-orm/pg-core';
import { createSelectSchema } from 'drizzle-valibot';
import { parse } from 'valibot';

const users = pgTable('users', {
  id: integer().generatedAlwaysAsIdentity().primaryKey(),
  name: text().notNull(),
  age: integer().notNull()
});

const userSelectSchema = createSelectSchema(users);

const rows = await db.select({ id: users.id, name: users.name }).from(users).limit(1);
const parsed: { id: number; name: string; age: number } = parse(userSelectSchema, rows[0]); // Error: `age` is not returned in the above query

const rows = await db.select().from(users).limit(1);
const parsed: { id: number; name: string; age: number } = parse(userSelectSchema, rows[0]); // Will parse successfully

也支持视图和枚举。

import { pgEnum } from 'drizzle-orm/pg-core';
import { createSelectSchema } from 'drizzle-valibot';
import { parse } from 'valibot';

const roles = pgEnum('roles', ['admin', 'basic']);
const rolesSchema = createSelectSchema(roles);
const parsed: 'admin' | 'basic' = parse(rolesSchema, ...);

const usersView = pgView('users_view').as((qb) => qb.select().from(users).where(gt(users.age, 18)));
const usersViewSchema = createSelectSchema(usersView);
const parsed: { id: number; name: string; age: number } = parse(usersViewSchema, ...);

插入模式

定义要插入到数据库中的数据的形状 - 可用于验证 API 请求。

import { pgTable, text, integer } from 'drizzle-orm/pg-core';
import { createInsertSchema } from 'drizzle-valibot';
import { parse } from 'valibot';

const users = pgTable('users', {
  id: integer().generatedAlwaysAsIdentity().primaryKey(),
  name: text().notNull(),
  age: integer().notNull()
});

const userInsertSchema = createInsertSchema(users);

const user = { name: 'John' };
const parsed: { name: string, age: number } = parse(userInsertSchema, user); // Error: `age` is not defined

const user = { name: 'Jane', age: 30 };
const parsed: { name: string, age: number } = parse(userInsertSchema, user); // Will parse successfully
await db.insert(users).values(parsed);

更新模式

定义要在数据库中更新的数据的形状 - 可用于验证 API 请求。

import { pgTable, text, integer } from 'drizzle-orm/pg-core';
import { createUpdateSchema } from 'drizzle-valibot';
import { parse } from 'valibot';

const users = pgTable('users', {
  id: integer().generatedAlwaysAsIdentity().primaryKey(),
  name: text().notNull(),
  age: integer().notNull()
});

const userUpdateSchema = createUpdateSchema(users);

const user = { id: 5, name: 'John' };
const parsed: { name?: string | undefined, age?: number | undefined } = parse(userUpdateSchema, user); // Error: `id` is a generated column, it can't be updated

const user = { age: 35 };
const parsed: { name?: string | undefined, age?: number | undefined } = parse(userUpdateSchema, user); // Will parse successfully
await db.update(users).set(parsed).where(eq(users.name, 'Jane'));

每个创建模式函数都接受一个额外的可选参数，您可以使用它来扩展、修改或完全覆盖字段的模式。定义回调函数将扩展或修改，而提供 Valibot 模式将覆盖它。

import { pgTable, text, integer, json } from 'drizzle-orm/pg-core';
import { createSelectSchema } from 'drizzle-valibot';
import { parse, pipe, maxLength, object, string } from 'valibot';

const users = pgTable('users', {
  id: integer().generatedAlwaysAsIdentity().primaryKey(),
  name: text().notNull(),
  bio: text(),
  preferences: json()
});

const userSelectSchema = createSelectSchema(users, {
  name: (schema) => pipe(schema, maxLength(20)), // Extends schema
  bio: (schema) => pipe(schema, maxLength(1000)), // Extends schema before becoming nullable/optional
  preferences: object({ theme: string() }) // Overwrites the field, including its nullability
});

const parsed: {
  id: number;
  name: string,
  bio?: string | undefined;
  preferences: {
    theme: string;
  };
} = parse(userSelectSchema, ...);
