Order states

Orders are often queried by one of more possible states they can be in. Below is a chart of all the possible states.

State:	open	closed	upcoming	active	inactive
start date	Any	Past	Future	Up through today	Future
end date	Future	Past	Future	Today forward	Past
canceled	No	Coerced	No	No	Coerced
comparison	and	and	and	and	or

Legend:

• canceled = No means that if the order is canceled it cannot be this state.
• canceled = Coerced means that the order will automatically be in this state by virtue of the fact it is canceled.
• comparison describes how the start date and end date of the order are compared. For instance, an open order can have any start date and an end date in the future. An inactive order can have a start date in the future or an end date in the past.

QuerySet filtering

Corresponding to the table above, orders have custom QuerySet functions for each of the states. For instance, Order.objects.open() or Order.objects.active().
