Steedos Seed Data | Steedos 初始化数据

Overview | 概述

Seed data files provide initial records that are automatically imported when the service starts or a workspace initializes. They are placed in main/default/data/ and support JSON, YAML, and CSV formats.

初始化数据文件提供服务启动或工作区初始化时自动导入的初始记录，放在 main/default/data/ 目录下，支持 JSON、YAML、CSV 格式。

File Location | 文件位置

steedos-packages/
└── my-package/
    └── main/default/
        └── data/
            ├── products.data.json
            ├── categories.data.yml
            └── regions.data.csv

Naming Convention | 命名规则

{objectName}.data.json
{objectName}.data.yml
{objectName}.data.csv

The file name before the first . is the object API name (i.e. the MongoDB collection name).

文件名第一个 . 之前的部分是对象 API 名称（即 MongoDB collection 名称）。

File Structure | 文件结构

JSON Format | JSON 格式

[
  {
    "_id": "product_001",
    "name": "标准服务套餐",
    "price": 9800,
    "status": "active"
  },
  {
    "_id": "product_002",
    "name": "高级服务套餐",
    "price": 19800,
    "status": "active"
  }
]

YAML Format | YAML 格式

- _id: "product_001"
  name: "标准服务套餐"
  price: 9800
  status: "active"

- _id: "product_002"
  name: "高级服务套餐"
  price: 19800
  status: "active"

CSV Format | CSV 格式

_id,name,price,status
product_001,标准服务套餐,9800,active
product_002,高级服务套餐,19800,active

Required Fields | 必填字段

Field	Description
_id	Unique record identifier. Required for every record.

The following fields are auto-populated on import (do NOT include them manually):

Auto Field	Description
space	Workspace ID
owner	Workspace owner
created	Creation timestamp
created_by	Creator
modified	Modification timestamp
modified_by	Modifier
company_id	Company ID
company_ids	Company IDs

Autonumber Fields | 自动编号字段

⚠️ CRITICAL: autonumber fields do NOT auto-generate values during seed data import. You MUST explicitly set values for autonumber fields in seed data files.

⚠️ 重要：autonumber 类型字段在初始化数据导入时不会自动生成编号，必须在数据文件中手动设置值。

Autonumber fields (e.g., order_number with formula ORD-{YYYY}{MM}{DD}-{0000}) only auto-generate when records are created through the UI or API. During seed data import, if you omit the autonumber field, it will be empty/null.

自动编号字段（如 order_number，公式 ORD-{YYYY}{MM}{DD}-{0000}）仅在通过界面或 API 创建记录时自动生成。导入初始化数据时，如果不设置该字段，值将为空。

# ✅ CORRECT — explicitly set autonumber field values
- _id: "order_001"
  order_number: "ORD-20240101-0001"
  customer: "客户A"
  amount: 9800

- _id: "order_002"
  order_number: "ORD-20240101-0002"
  customer: "客户B"
  amount: 19800

# ❌ WRONG — omitting autonumber field, value will be null
- _id: "order_003"
  customer: "客户C"
  amount: 29800

Template Variables | 模板变量

Use template variables for workspace-dependent IDs:

Variable	Replaced With
${space_id}	Current workspace ID
${space_owner_id}	Workspace owner user ID

- _id: "${space_id}_default_config"
  name: "default_config"
  space: "${space_id}"
  owner: "${space_owner_id}"
  setting_key: "theme"
  setting_value: "blue"

Date Format | 日期格式

⚠️ CRITICAL: date and datetime field values MUST be valid date formats. Do NOT use arbitrary strings, descriptive text, or non-date values.

⚠️ 重要：date 和 datetime 类型字段的值必须是合法的日期格式，严禁使用任意字符串或非日期值。

JSON Format — Use EJSON $date | JSON 格式 — 使用 EJSON $date

[
  {
    "_id": "record_001",
    "name": "示例记录",
    "start_date": { "$date": "2024-01-15T00:00:00.000Z" },
    "submitted_at": { "$date": "2024-03-20T08:30:00.000Z" }
  }
]

YAML Format — Use ISO Date Strings | YAML 格式 — 使用 ISO 日期字符串

In YAML, js-yaml automatically parses ISO date strings as Date objects:

- _id: "record_001"
  name: "示例记录"
  start_date: 2024-01-15              # date type — date only
  submitted_at: 2024-03-20T08:30:00Z  # datetime type — date and time

Valid Date Formats | 有效日期格式

Field Type	JSON Format	YAML Format	Example
date	{ "$date": "2024-01-15T00:00:00.000Z" }	2024-01-15	Date only
datetime	{ "$date": "2024-03-20T08:30:00.000Z" }	2024-03-20T08:30:00Z	Date and time

⚠️ INVALID examples (will cause errors):

# ❌ WRONG — arbitrary strings, not valid dates
start_date: "today"
start_date: "next week"
start_date: "2024年1月"
start_date: "TBD"
start_date: "Q1 2024"

# ❌ WRONG — template expressions (not supported for date fields)
start_date: "{now}"         # {now} only works as defaultValue in field definitions
submitted_at: "{today}"

# ✅ CORRECT
start_date: 2024-01-15
start_date: 2024-01-15T00:00:00Z
submitted_at: 2024-03-20T08:30:00Z

Import Behavior | 导入行为

Seed data is imported at two points:

Trigger	Mode	Behavior
Service startup	onlyInsert	Only imports if records do NOT already exist. If any record by _id is found, the entire import is skipped.
Space initialized	upsert	Inserts new records, updates existing records (matched by _id).

On upsert, existing records preserve their original space, owner, created, created_by values; only modified and modified_by are updated.

Best Practices | 最佳实践

1. Always include _id: Every record must have a unique _id. Use ${space_id} prefix for workspace-scoped data.
2. Date fields MUST use valid date format: date fields use 2024-01-15 (YAML) or { "$date": "..." } (JSON). datetime fields use 2024-01-15T08:30:00Z (YAML) or { "$date": "..." } (JSON). Never use arbitrary strings.（日期字段必须使用合法日期格式，严禁使用任意字符串）
3. Use YAML for readability: YAML is easier to maintain than JSON for seed data.
4. Don't set auto fields: Do not include space, owner, created, created_by, modified, modified_by — they are auto-populated.
5. Always set autonumber fields: Autonumber fields do NOT auto-generate during import. You must provide explicit values matching the field's formula pattern (e.g., ORD-20240101-0001).（自动编号字段在导入时不会自动生成，必须手动设置值）
6. Idempotent IDs: Use deterministic _id values (not random) so repeated imports don't create duplicates.
7. Match object API name: The filename must exactly match the object's API name (e.g., orders.data.yml for the orders object).
8. Keep data minimal: Only include essential initial data (config, default options, system records). Don't use for large datasets.
