django-hordak 1.0.0

Double entry book keeping in Django

Double entry book keeping in Django.

The initial priority is to ensure the model layer works reliably. Ultimately the intention is to integrate this with swiftwind to provide an accounting & billing system for a communal household. This interface should be intuitive and suitable for non-experts.

Installation

Installation using pip:

pip install django-hordak  # Release coming soon

Tested against:

• Django >= 1.8, <= 1.10

• Python 2.7, 3.4, 3.5, nightly

• Postgres 9

Hordak may work with Postgres 8, but this is not tested for.

It may also be possible to run Hordak on a non-Postgres RDBMS if one skips the *_check_* migrations, as these are Postgres-specific. However, this is not recommended as it could lead to database inconsistency.

Design

The core models consist of:

• Account - Such as ‘Accounts Receivable’, a bank account, etc. Accounts can be arranged as a tree structure, where the balance of the parent account is the summation of the balances of all its children.

• Transaction - Represents a movement between accounts. Each transaction must have two or more legs.

• Leg - Represents a flow of money into (debit) or out of (credit) a transaction. Debits are represented by negative amounts, and credits by positive amounts. The sum of all a transaction’s legs must equal zero. This is enforced with a database constraint.

Additionally, there are models which related to the import of external bank statement data:

• StatementImport - Represents a simple import of zero or more statement lines relating to a specific Account.

• StatementLine - Represents a statement line. StatementLine.create_transaction() may be called to create a transaction for the statement line.
