Kaget: Kawan Budget

README

Wallets hold the main source of everything.

A wallet can have two different types of balance-holding:
- CASH wallet
- DIGITAL wallet
Able to update the wallet name
Deletion will delete all data referencing the wallet, such as budgets and records (cascade)

Budgets are the main purpose of this app. Planning and maintaining a budget with ease.

Able to refund the balance to its source wallet
A budget is allocated based on the wallet’s origin. If the wallet is CASH, then the budget will act like the wallet, and vice versa.
Deletion will delete all data referencing the budget, such as records.
- A budget only deletable when its freshly created—not used. Which means no records for this budget at all.
- Deletion will roll back all unallocated budget to the wallet origin.
A budget will be archived when there is no balance can be used (0).
- The balance and used balance will be reset to 0 and the budget will become archived
- Able to reactivate the archived budget for next cycle from fresh state while previous record still intact
- When archived, no activity can be performed within this budget: delete, add balance, and refund.

A central place to record your cash flow.

A record will have several properties and use the polymorphic table to provide the flexibility
- source_type → WALLET, BUDGET, BUDGET_ITEM
- record_type → INCOME, EXPENSE, LOAN, DEBT, DEBT_REPAYMENT, DEBT_COLLECTION
A record can have a sub-item
- Each sub-item will only have a note and amount
Deletion will delete all data that reference the record, such as record sub-item (CASCADE)
- Deletion will roll back the amount to the respective source.

Track internal fund movement between wallet and budget.

A transfer will have two records for each transfer. One is for incoming funds and the other is for outgoing funds.
A transfer can record a transfer fee.
A transfer will save the source and destination data as a snapshot to prevent errors when either the source or destination is deleted.
A transfer can not be deleted.
