#UPDATE: October 30, 2015 Django 1.8, Ubuntu Server 14.04, literati.nyc
#1 note that by the time automatic notifications were immplemented,
#I used crontab to schedule some recurrent events
#files with the name like 'task8am.sh' load a module through django shell
#in order to render templates I used a Django shortcut - render_to_string
#while testing I found that this does not work and return an error.
#Nevertheless, I was able to troubleshoot it and edited some code in
#/usr/local/lib/python3.4/dist-packages/django/utils/translation/trans_real.py
#It seems that check_for_language and get_language_bidi methods are not
willing
#to accept None values. I hope it will be resolved in the following
versions of
#Django, but for now, here is my patch
#256 def get_language_bidi():
#257 """
#258 Returns selected language's BiDi layout.
#259
#260 * False = left-to-right layout
#261 * True = right-to-left layout
#262 """
#263 base_lang = get_language()
#264 if base_lang is None:
#265 return False
#266 base_lang = get_language().split('-')[0]
#267 return base_lang in settings.LANGUAGES_BIDI
