- 導入 Prisma 7.9.1 + SQLite(better-sqlite3 driver adapter),prisma.config.ts 管理連線設定 - 完整資料模型:User/Work/Character/CharacterAlias/EpisodicMemory/SemanticMemory/ ProceduralRule/EmotionState/Relationship/SentimentLedgerEntry - packages/db:Prisma Client 存取層(ESM,因 Prisma 7 產出的 generated client 僅支援 ESM) - apps/api 隨之改為 ESM 以相容 packages/db - packages/shared:新增角色/記憶/情緒/關係共用型別,api 與 web 皆從此匯入 - prisma/seed.ts:建立測試使用者與元氣型測試角色,含完整關係帳本與記憶種子資料 - apps/api:新增 GET /characters - scripts/smoke/B.mjs:驗證資料表齊全、API 讀出種子角色、關係與記憶可寫入讀出 - 保留 Prisma 官方隨 CLI 附的 agent skill 文件(.agents/skills 等),供後續群組查閱 npm run restart && npm run smoke -- B 皆通過(B-V),A 群組冒煙測試無回歸。

prisma db seed
Runs your database seed script to populate data.
Command
prisma db seed [options]
What It Does
- Executes your configured seed script
- Populates database with initial/test data
- Runs independently (not auto-run by migrations in v7)
Options
| Option | Description |
|---|---|
--config |
Custom path to your Prisma config file |
-- |
Pass custom arguments to seed script |
Configuration
Configure seed script in prisma.config.ts:
import 'dotenv/config'
import { defineConfig, env } from 'prisma/config'
export default defineConfig({
schema: 'prisma/schema.prisma',
migrations: {
path: 'prisma/migrations',
seed: 'tsx prisma/seed.ts', // Your seed command
},
datasource: {
url: env('DATABASE_URL'),
},
})
Common seed commands
// TypeScript with tsx
seed: 'tsx prisma/seed.ts'
// TypeScript with ts-node
seed: 'ts-node prisma/seed.ts'
// JavaScript
seed: 'node prisma/seed.js'
Seed Script Example
// prisma/seed.ts
import { PrismaClient } from '../generated/client'
const prisma = new PrismaClient()
async function main() {
// Create users
const alice = await prisma.user.upsert({
where: { email: 'alice@prisma.io' },
update: {},
create: {
email: 'alice@prisma.io',
name: 'Alice',
posts: {
create: {
title: 'Hello World',
published: true,
},
},
},
})
const bob = await prisma.user.upsert({
where: { email: 'bob@prisma.io' },
update: {},
create: {
email: 'bob@prisma.io',
name: 'Bob',
},
})
console.log({ alice, bob })
}
main()
.then(async () => {
await prisma.$disconnect()
})
.catch(async (e) => {
console.error(e)
await prisma.$disconnect()
process.exit(1)
})
Examples
Run seed
prisma db seed
With custom arguments
prisma db seed -- --environment development
Arguments after -- are passed to your seed script.
Current Workflow
Run seeding explicitly after migrations when you need seed data:
prisma migrate dev --name init
prisma generate
prisma db seed # Must run explicitly
Idempotent Seeding
Use upsert to make seeds re-runnable:
// Good: Can run multiple times
await prisma.user.upsert({
where: { email: 'alice@prisma.io' },
update: {}, // Don't change existing
create: { email: 'alice@prisma.io', name: 'Alice' },
})
// Bad: Fails on second run
await prisma.user.create({
data: { email: 'alice@prisma.io', name: 'Alice' },
})
Common Patterns
Development reset
prisma migrate reset --force
prisma db seed
Conditional seeding
// prisma/seed.ts
const count = await prisma.user.count()
if (count === 0) {
// Only seed if empty
await seedUsers()
}
Environment-specific seeds
// prisma/seed.ts
const env = process.env.NODE_ENV || 'development'
if (env === 'development') {
await seedDevData()
} else if (env === 'test') {
await seedTestData()
}
Best Practices
- Use
upsertfor idempotent seeds - Keep seeds focused and minimal
- Use realistic but fake data
- Document required seed data
- Version control your seed scripts
