TypeError: isoformat() takes no arguments (1 given)

[pawl]

I was getting the following error because of that line:
TypeError: isoformat() takes no arguments (1 given)

Using datetime worked, I converted my date object to datetime using: datetime.datetime.combine(, datetime.time(0))

Yeah, it should probably be cleverer and handle date objects.

Would line 282 in types.py look like this?:

def _unparse(self, value):
    if value is datetime.date:
        return value.isoformat()
    if value is datetime.date:
        return value.isoformat(' ')
    else:
        return value.isoformat(' ') # or maybe an error message?
