From 1a28ec59eb7f56d785b61b9bc2f7341e7052507f Mon Sep 17 00:00:00 2001 From: padreug Date: Thu, 23 Oct 2025 00:03:32 +0200 Subject: [PATCH] Completes Phase 1: Beancount patterns adoption Implements core improvements from Phase 1 of the Beancount patterns adoption: - Uses Decimal for fiat amounts to prevent floating point errors - Adds a meta field to journal entries for a full audit trail - Adds a flag field to journal entries for transaction status - Migrates existing account names to a hierarchical format This commit introduces a database migration to add the `flag` and `meta` columns to the `journal_entries` table. It also includes updates to the models, CRUD operations, and API endpoints to handle the new fields. --- PHASE1_COMPLETE.md | 197 +++++++++++++++++++++++++++++++++++++++++ account_utils.py | 215 +++++++++++++++++++++++++++++++++++++++++++++ crud.py | 62 ++++++++++--- migrations.py | 93 ++++++++++++++++++++ models.py | 21 ++++- static/js/index.js | 4 +- views_api.py | 55 +++++++++--- 7 files changed, 616 insertions(+), 31 deletions(-) create mode 100644 PHASE1_COMPLETE.md create mode 100644 account_utils.py diff --git a/PHASE1_COMPLETE.md b/PHASE1_COMPLETE.md new file mode 100644 index 0000000..8edf589 --- /dev/null +++ b/PHASE1_COMPLETE.md @@ -0,0 +1,197 @@ +# Phase 1 Implementation - Complete โœ… + +## Summary + +We've successfully implemented the core improvements from Phase 1 of the Beancount patterns adoption: + +## โœ… Completed + +### 1. **Decimal Instead of Float for Fiat Amounts** +- **Files Changed:** + - `models.py`: Changed all fiat amount fields from `float` to `Decimal` + - `ExpenseEntry.amount` + - `ReceivableEntry.amount` + - `RevenueEntry.amount` + - `UserBalance.fiat_balances` dictionary values + - `crud.py`: Updated fiat balance calculations to use `Decimal` + - `views_api.py`: Store fiat amounts as strings with `str(amount.quantize(Decimal("0.001")))` + +- **Benefits:** + - Prevents floating point rounding errors + - Exact decimal arithmetic + - Financial-grade precision + +### 2. **Meta Field for Journal Entries** +- **Database Migration:** `m005_add_flag_and_meta` + - Added `meta TEXT DEFAULT '{}'` column to `journal_entries` table + +- **Model Changes:** + - Added `meta: dict = {}` to `JournalEntry` and `CreateJournalEntry` + - Meta stores: source, created_via, user_id, payment_hash, etc. + +- **CRUD Updates:** + - `create_journal_entry()` now stores meta as JSON + - `get_journal_entries_by_user()` parses meta from JSON + +- **API Integration:** + - Expense entries: `{"source": "api", "created_via": "expense_entry", "user_id": "...", "is_equity": false}` + - Receivable entries: `{"source": "api", "created_via": "receivable_entry", "debtor_user_id": "..."}` + - Payment entries: `{"source": "lightning_payment", "created_via": "record_payment", "payment_hash": "...", "payer_user_id": "..."}` + +- **Benefits:** + - Full audit trail for every transaction + - Source tracking (where did this entry come from?) + - Can add tags, links, notes in future + - Essential for compliance and debugging + +### 3. **Flag Field for Transaction Status** +- **Database Migration:** `m005_add_flag_and_meta` + - Added `flag TEXT DEFAULT '*'` column to `journal_entries` table + +- **Model Changes:** + - Created `JournalEntryFlag` enum: + - `*` = CLEARED (confirmed/reconciled) + - `!` = PENDING (awaiting confirmation) + - `#` = FLAGGED (needs review) + - `x` = VOID (cancelled) + - Added `flag: JournalEntryFlag` to `JournalEntry` and `CreateJournalEntry` + +- **CRUD Updates:** + - `create_journal_entry()` stores flag as string value + - `get_journal_entries_by_user()` converts string to enum + +- **API Logic:** + - Expense entries: Default to CLEARED (immediately confirmed) + - Receivable entries: Start as PENDING (unpaid debt) + - Payment entries: Mark as CLEARED (payment received) + +- **Benefits:** + - Visual indication of transaction status in UI + - Filter transactions by status + - Supports reconciliation workflows + - Standard accounting practice (Beancount-style) + +## ๐Ÿ“Š Migration Details + +**Migration `m005_add_flag_and_meta`:** +```sql +ALTER TABLE journal_entries ADD COLUMN flag TEXT DEFAULT '*'; +ALTER TABLE journal_entries ADD COLUMN meta TEXT DEFAULT '{}'; +``` + +**To Apply:** +1.
