# Aplikasi Catat Jual-Beli Saham — Odoo 17 + Flutter
|
||
|
||
Backend Odoo ERP (Community 17) untuk mencatat pembelian & penjualan saham,
|
||
diakses dari aplikasi **Flutter** (Android).
|
||
|
||
## Arsitektur
|
||
```
|
||
Flutter app (Android) ──JSON-RPC──► Odoo 17 (Python)
|
||
│ custom addon: saat_invest
|
||
▼
|
||
PostgreSQL 16
|
||
```
|
||
|
||
## Stack
|
||
|
||
| Layer | Teknologi | Port |
|
||
|---|---|---|
|
||
| Backend | Odoo 17 Community (`odoo:17.0`) | `18069` (host) |
|
||
| Database | PostgreSQL 16 (`postgres:16`) | internal (5432, tdk di-publish) |
|
||
| Mobile | Flutter (Android) | — |
|
||
|
||
## Struktur proyek
|
||
```
|
||
saat-app/
|
||
├── docker-compose.yml # Odoo 17 + PostgreSQL 16
|
||
├── .env # RAHASIA: password (jangan commit)
|
||
├── addons/ # custom addon buatan sendiri (saat_invest)
|
||
└── README.md
|
||
```
|
||
|
||
## Cara menjalankan
|
||
```bash
|
||
cd /home/ardhi/Application/saat-app
|
||
docker compose config # validasi
|
||
docker compose up -d # start
|
||
```
|
||
|
||
Akses UI: http://localhost:18069 — login `admin` dengan password
|
||
`ODOO_ADMIN_PASSWORD` di `.env`.
|
||
|
||
## Troubleshooting
|
||
|
||
### `PermissionError: /var/lib/odoo/sessions`
|
||
|
||
Odoo 17 berjalan sebagai user dengan UID/GID `101`. Perbaiki ownership
|
||
named volume Odoo tanpa menghapus database atau filestore:
|
||
|
||
```bash
|
||
cid=$(docker compose ps -q odoo)
|
||
docker exec --user root "$cid" sh -c \
|
||
'chown -R 101:101 /var/lib/odoo && \
|
||
chmod 755 /var/lib/odoo && chmod 700 /var/lib/odoo/sessions'
|
||
```
|
||
|
||
Verifikasi bahwa user Odoo dapat menulis session:
|
||
|
||
```bash
|
||
docker exec --user odoo "$cid" sh -c \
|
||
'touch /var/lib/odoo/sessions/.write-check && \
|
||
rm /var/lib/odoo/sessions/.write-check'
|
||
```
|
||
|
||
Gunakan satu volume utama berikut pada `docker-compose.yml`; jangan membuat
|
||
mount terpisah untuk `/var/lib/odoo/session` (singular):
|
||
|
||
```yaml
|
||
volumes:
|
||
- saat_odoo_filestore:/var/lib/odoo
|
||
```
|
||
|
||
### `column res_lang.short_time_format does not exist`
|
||
|
||
Pastikan versi image Odoo sama dengan versi database. Database proyek ini
|
||
adalah Odoo 17, jadi gunakan:
|
||
|
||
```yaml
|
||
image: odoo:17.0
|
||
```
|
||
|
||
Jangan menjalankan database Odoo 17 dengan image Odoo 18 tanpa proses upgrade
|
||
major-version yang resmi.
|
||
|
||
### Tidak bisa login sebagai `admin`
|
||
|
||
Jika log menunjukkan `Login failed` dan user `admin` aktif, reset password
|
||
melalui ORM Odoo menggunakan nilai `ODOO_ADMIN_PASSWORD` dari `.env`:
|
||
|
||
```bash
|
||
set -a && source .env && set +a
|
||
docker compose exec -T -e RESET_PASSWORD="$ODOO_ADMIN_PASSWORD" odoo \
|
||
odoo shell -d "$POSTGRES_DB" --db_host=db --db_port=5432 \
|
||
--db_user="$POSTGRES_USER" --db_password="$POSTGRES_PASSWORD" --no-http <<'PY'
|
||
import os
|
||
user = env['res.users'].search([('login', '=', 'admin')], limit=1)
|
||
if not user.exists() or not user.active:
|
||
raise RuntimeError('Active admin user was not found')
|
||
user.write({'password': os.environ['RESET_PASSWORD']})
|
||
env.cr.commit()
|
||
print('Admin password reset')
|
||
PY
|
||
```
|
||
|
||
Setelah itu login dengan user `admin` dan password `ODOO_ADMIN_PASSWORD`.
|
||
|
||
## Status
|
||
- ✅ Odoo 17 container jalan (port 18069), DB PostgreSQL 16 healthy
|
||
- ✅ JSON-RPC aktif (uid `admin` verified) — endpoint yang akan dipakai Flutter
|
||
- ✅ **Addon `saat_invest` terinstal** (model saham, transaksi, portofolio + seed 5 saham IDX)
|
||
- ✅ **Portofolio auto-sync**: otomatis diperbarui tiap transaksi ditambah/ubah/hapus
|
||
(tidak perlu tombol manual; buka menu Portofolio selalu datanya segar)
|
||
- ✅ **Live harga pasar (cron)**: ambil & update harga dari Yahoo Finance (.JK)
|
||
tiap 6 menit SAAT jam bursa IDX (08:45–16:00 WIB). Update hanya bila berubah.
|
||
- ✅ End-to-end teruji: buat beli/jual → portofolio ter-update → hitung avg cost & realized/unrealized P/L
|
||
- ⏳ Aplikasi Flutter (login, catat jual/beli, portfolio, P/L)
|
||
|
||
## Install / upgrade addon saat_invest
|
||
```bash
|
||
cd /home/ardhi/Application/saat-app
|
||
set -a && source .env && set +a
|
||
# install pertama kali
|
||
docker exec -e PASSWORD="$POSTGRES_PASSWORD" saat-odoo odoo \
|
||
-d "$POSTGRES_DB" --db_host=db --db_user="$POSTGRES_USER" \
|
||
--db_password="$POSTGRES_PASSWORD" --no-http --stop-after-init -i saat_invest
|
||
# upgrade setelah ubah kode
|
||
docker exec -e PASSWORD="$POSTGRES_PASSWORD" saat-odoo odoo \
|
||
-d "$POSTGRES_DB" --db_host=db --db_user="$POSTGRES_USER" \
|
||
--db_password="$POSTGRES_PASSWORD" --no-http --stop-after-init -u saat_invest
|
||
docker restart saat-odoo
|
||
```
|
||
|
||
> Catatan Odoo: `<list>` view di Odoo 17 kadang bermasalah, pakai `<tree>`
|
||
> (kompatibel lintas versi) seperti yang sudah dilakukan.
|
||
|
||
## API untuk Flutter (via JSON-RPC `execute_kw`)
|
||
Semua melalui `POST /jsonrpc` dengan `{service:'object', method:'execute_kw'}`.
|
||
Login: `common.authenticate(db, user, pass)` → `uid`.
|
||
- List saham: `saat.saham search_read [domain] {fields}`
|
||
- Catat transaksi: `saat.transaksi create [{vals}]`
|
||
- List transaksi: `saat.transaksi search_read [domain] {fields}`
|
||
- **Rekalkulasi portofolio**: `saat.portofolio action_recalculate [[]]`
|
||
- Baca portofolio: `saat.portofolio search_read [domain] {fields}`
|
||
(sisa_lembar, avg_cost, total_beli_biaya, realized_pl, unrealized_pl, nilai_sekarang)
|
||
|
||
## Catatan keamanan
|
||
- `.env` berisi rahasia → **tidak boleh di-commit** (sudah di `.gitignore`)
|
||
- PostgreSQL tidak di-publish ke host, hanya akses antar-container
|
||
- Ganti `ADMIN_PASSWD` segera setelah setup awal
