swingtix-bookkeeper 0.0.6

你好，世界

你需要一个django项目。如果你手边没有，你可以做一个空的 django tutorial的第一步。之后， 编辑<；yourproject>；/settings.py将“swingtix.bookkeeper”添加到已安装的应用程序并运行：

$ python manage.py syncdb

然后您就可以开始使用shell进行探索：

$ python manage.py shell

首先，我们创建几个帐户：

>>> from swingtix.bookkeeper.models import BookSet, Account

>>> book = BookSet(description="my book")
>>> book.save()

>>> revenue  = Account(bookset=book, name="revenue", positive_credit=True)
>>> revenue.save()
>>> bank     = Account(bookset=book, name="bank",    positive_credit=False)
>>> bank.save()
>>> expense  = Account(bookset=book, name="expense", positive_credit=False)
>>> expense.save()

然后您可以使用它们：

>>> book = BookSet.objects.get(description="my book")
>>> revenue = book.get_account("revenue")
>>> bank    = book.get_account("bank")
>>> expense = book.get_account("expense")

#Someone pays you can advance.  Yay!
>>> bank.debit(120.00, revenue, "our first sale")
(<AccountEntry: 120 >, <AccountEntry: -120 >)

#but now you have to do some work.  The local coffee shop has free wifi..
>>> bank.credit(2.20, expense, "coffee")
(<AccountEntry: -2 >, <AccountEntry: 2 >)

>>> bank.balance()
Decimal('117.80')
>>> expense.balance()
Decimal('2.20')
>>> revenue.balance()
Decimal('120.00')
