Error when adding date to titles in recipes

[anthonyliu]

Hi! I am a complete newbie, so please bear with me if I am making any silly mistakes.

I am trying to customize the built-in recipes by adding the date to the title. By following the instructions in the Calibre manual, I added "import time" and put " + time.strftime('%d %b %Y')" in the title line (these are the only changes I made to the recipe).

So the recipe looks something like this:

#!/usr/bin/env  python

__license__   = 'GPL v3'
__copyright__ = '2008, Kovid Goyal <kovid at kovidgoyal.net>'
'''
economist.com
'''
from calibre.web.feeds.news import BasicNewsRecipe
from calibre.ebooks.BeautifulSoup import Tag, NavigableString
from collections import OrderedDict

import time, re

class Economist(BasicNewsRecipe):

    title = 'The Economist' + time.strftime('%d %b %Y')

But when I hit the Add/Update Recipe botton, I got the following error message:

calibre, version 0.9.7
ERROR: Unhandled exception: <b>UnicodeDecodeError</b>:'utf8' codec can't decode byte 0xd4 in position 20: invalid continuation byte

I've been having this problem for months, and all your input and assistance will be very appreciated! Thank you!

Use

from calibre import strftime

rather than time.strftime

It is working now. Thank you!

Hi, can you tell me what I am doing wrong in the below script? I believe I followed the explanations above. I am trying to make the title show as follows: The Economist - 2012 Dec 22. In the recipe I changed only the below line:


title = 'The Economist - ' + from calibre import strftime('%Y %b %d')

[kovidgoyal]

You need

title = 'The Economist' + time.strftime('%d %b %Y')

Thanks a lot and Happy New Year!!!
