hoelee 4693c9d684 feat(W4): daily full reconciliation — user/role drift repair + ReconcileLogs audit
- w4-body.js: ONE-DIRECTIONAL sync (NocoDB status = SOT, never reverse);
  drift matrix: missing user/role (provision w/ username lookup to avoid
  duplicates), dangling refs (adopt/recreate), disabled<->status, canonical
  base_path '/' + permission 16384, scopes vs calculateEffectiveGrants,
  username drift detect+log_only; verify-after-repair on every change;
  password never pushed on repair (方案 C); dry-run via ?dryRun=true
- gen_w4.js: daily 03:00 cron + webhook alist-w4-reconcile; API-import-safe
  (UUID node ids, no pinData, webhookId)
- ReconcileLogs table mktsb7le6fqr2u1 (add_reconcilelogs_table.py, idempotent,
  v2 API); FK column nc_jitu___Customers_id for bt-link writes (v2 ignores
  link column itself)
- test_w4_reconcile.js: 34 assertions / 12 mock worlds, ALL PASSED
- live-verified against production: dry-run (3 drifts + 1 error found),
  real repair (3 repaired, verify all passed, 4 log rows), idempotent rerun
- NocoDB 2026.08.x pitfalls documented (v1 col endpoints gone, row delete
  via body [{Id}]); n8n API import/activation pitfalls (activeVersionId)
- docs: W4-DESIGN.md new; DATABASE_SCHEMA 8 tables; N8N_WORKFLOWS, SETUP,
  PROJECT_STATE updated

n8n Setup — Environment Variables

W1/W2 通过一个 in-flow 的 "Load Env" Code 节点(webhook 之后第 2 步)读取全部 env, 下游所有节点引用 $('Load Env').item.json.VAR。secrets 不硬编码进 workflow。

读取方式(已实测确认)

  • Code 节点内:$env.VAR 可用(例 $env.NOCODB_URL)。✔
  • HTTP 节点表达式字段(url / header / body expression):$env 和 process.env 都不可用。✘
  • 所以用一个 Code 节点 "Load Env" 在 $env 里调取全部 env 输出到 $json, 下游 HTTP 节点用 {{ $('Load Env').item.json.VAR }} 取值。

关键点:

  • Load Env 必须接在 webhook flow 里(第 2 步),不在 flow 里的 Code 节点不会执行。
  • Load Env 必须透传传入的字段(customerId / customerProductId),否则下游丢数据。

Load Env 模板(实测可用)

// Step 2: read ALL env via $env (works in Code node), and pass through
// the webhook-derived fields so downstream keeps customerId.
const prev = $input.item.json;
return { json: {
  customerId: prev.customerId,
  eventType: prev.eventType,
  NOCODB_URL: $env.NOCODB_URL,
  NOCODB_TOKEN: $env.NOCODB_TOKEN,
  T_CUSTOMERS: $env.NOCODB_TABLE_CUSTOMERS,
  ALIST_URL: $env.ALIST_URL,
  ALIST_ADMIN_USERNAME: $env.ALIST_ADMIN_USERNAME,
  ALIST_ADMIN_PASSWORD: $env.ALIST_ADMIN_PASSWORD,
  ALIST_ADMIN_OTP: $env.ALIST_ADMIN_OTP || '',
} };

需要配置的 env(n8n 容器环境变量)

NOCODB_URL=https://nocodb.hoelee.com
NOCODB_TOKEN=<workspace token>
NOCODB_TABLE_CUSTOMERS=maqb9zgvza2te3k
NOCODB_TABLE_PRODUCTS=molyb3pxv81l75g
NOCODB_TABLE_RESOURCES=m6cm7tkxzd8m18c
NOCODB_TABLE_CUSTOMERPRODUCTS=mvyqbv8ao7u6bct
NOCODB_TABLE_ACCESSGRANTS=mxdx3yhfcyej3ao
NOCODB_TABLE_RECONCILELOGS=mktsb7le6fqr2u1
NOCODB_FK_RECONCILELOG_CUSTOMER=nc_jitu___Customers_id
NOCODB_LINK_PROD_RESOURCES=c4ko4x8kwi16swg
ALIST_URL=http://alist-serve-resource:5244
ALIST_ADMIN_USERNAME=hoelee
ALIST_ADMIN_PASSWORD=<admin 密码>

改完 env 必须重建 n8n 容器(不是 restart)。

导入步骤

  1. n8n → Import from File → W1-customer-provision.json / W2-customerproduct-sync.json。
  2. Webhook 节点 → Copy Webhook URL。
  3. NocoDB → 对应表 → 建 Webhook(After Insert + After Update)粘 URL:
    • Customers 表 → W1;CustomerProducts 表 → W2。

AList user 创建顺序(重要)

user/create 传空 role 会失败(admin or guest user can not be created,因 AList 把空 role 自动填成 guest 后拒绝)。必须先 role/create 建客户专属 role,再 user/create 传 role:[新roleId]。 详见 docs/API_INTEGRATION.md §9.7。

验证状态

  • ✅ W1 已实测跑通(create user 自动化成功)。
  • W2 待测(同 Load Env 模式已套用)。
