Feature: integrate with django

[amandegar]

It is not an issue. Feature request:
I have an idea to integrate this module with django to integrate Apps seamless with jalali calendar system.
I am not sure but i would like to share my idea with you.

Define flag in setting to choose calendar system. JALALI_CALENDAR_SYSTEM = True
Check if this flag is true:

1. substitute Date and DateTime field with jDate and jDateTime
2. forward datetime call to jdatetime

It is a brainstorming but i`m working on a such solution for django follow DRY principal and hide complexity from developer.

Thanks
