Django date YYYY-MM-DD

Question

I get date in format(YYYY-MM-DD)

Then I want to add timedelta

    mydate + timedelta(days=1)

and I get error

    coercing to Unicode: need string or buffer, datetime.timedelta found

Answer 1

mydate is a string. Try doing this:

from datetime import datetime
parsed_date = datetime.strptime(mydate, "%Y-%m-%d")

new_date = parsed_date + timedelta(days=1)

Answer 2

Data sent by the client will be sent as a Unicode and you have to parse it on server side

datetime.strptime(date, '%Y-%m-%d')

If it's part of a form, the data should be reformatted automatically when cleaned (though you might need to configure the field to accept the format you expect).

Answer 3

You have to convert your string date to python datetime :

>>> from datetime import datetime, timedelta
>>> dt_str = "2013/10/11"
>>> dt = datetime.strptime(dt_str, "%Y/%m/%d")
>>> new_dt = dt + timedelta(days=1)
>>> print new_dt
 datetime.datetime(2013, 10, 12, 0, 0)

If you now want to get the date as string:

>>> print new_dt.strftime("%Y/%m/%d")
 '2013/10/12'
