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

Here is the code where the error occurs:

date_arrive = datetime.datetime.strptime(request.session.get('arrival'), '%m/%d/%Y'),\
date_depart = date_arrive + datetime.timedelta(days=request.session.get('nights')))).save()

And everytime Django reaches this view, it throws the error:

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

Here arrival is a valid datetime object and nights is an integer.

You should be able to solve this problem by making sure non-unicode/non-strings like integers and datetime objects are surrounded with a str(your_date_object_here).

When I encountered this error in Django I was able to fix it with both the following:

def __str__(self): 
    return str(self.datetimeobject) + " other string return info"

and

def __str__(self):
    return unicode(self.datetimeobject) + " other string return info"

Id suggest you include full listing of function call.

Seems that you try concatenating unicode and datatime object, that is not possible. You have to convert date_arrive to datetime or "datetime.timedelta(days=request.session.get('nights')" to unicode evidently, depending on type your function needs as date_depart argument.
