DateTime and Date Converters

[captaincolonelfox]

I was trying to create such dataclass

@dataclass
class GetByDate:
    class Meta:
        namespace = NAMESPACE

    date: datetime = field(
        default=None,
        metadata={
            "name": "Date",
            "type": "Element"
        }
    )

But when I trying to proceed request with date in it I got a warning:

/xsdata/formats/converter.py:123: ConverterWarning: No converter registered for `<class 'datetime.datetime'>`
  warnings.warn(f"No converter registered for `{data_type}`", ConverterWarning)

And maybe it would be nice to have datetime converter which will try to parse from most common datetimes formats such as

for datetimes:

• %y-%m-%dT%H:%M:%S
• %y-%m-%d %H:%M:%S
• ...and so on

for dates:

• %y-%m-%d
• %d-%m-%y
• ...and so on

And by default it can serialize datetimes to %y-%m-%dT%H:%M:%S or a local time format.
So a user can specify in a serializer config which format he wants to have

I have avoided mapping the xs:date, xs:dateTime, xs:time to python datetime for some time now because of all the possible formats, but it's definitely in my todos.

For now there is a way to register a custom converter see here and the full script here

Awesome, will look forward for this changes!

because of all the possible formats

Not sure if it will be useful for you, but you can do try: ... except: continue on a list of different formats and return the first succeeded

And thank you, I didn't know you can implement your own converter. I guess I will do it for now

Hey @captaincolonelfox

Take a look here, I added support for custom date/time formats and standard iso 8601 xml date/times

It will be included in the next release
