While working on my website projects today I had the idea to use HTML/JS instead of a IP database to localize the dates and times shown on the websites.
Here are the snippets to use the JS snippets as filters for Django running on Google App Engine. You can use those filters on datetime objects.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 | # ./utils/localdatetimefilters.py
from time import mktime
from google.appengine.ext import webapp
def localdate(value, arg=None):
from django.conf import settings
from django.template import defaultfilters
if not value:
return ''
if arg is None:
arg = settings.DATE_FORMAT
content = '''<script type="text/javascript">document.write(new Date(%d).toLocaleDateString().replace(/\s[A-Z]{3}\+[0-9]{4}/, '').replace(/\s\([\s\w]+\)/, ''));</script><noscript>%s</noscript>''' % (
mktime(value.utctimetuple())*1000,
defaultfilters.date(value, arg)
)
return content
def localtime(value, arg=None):
from django.conf import settings
from django.template import defaultfilters
if not value:
return ''
if arg is None:
arg = settings.TIME_FORMAT
content = '''<script type="text/javascript">document.write(new Date(%d).toLocaleTimeString().replace(/\s[A-Z]{3}\+[0-9]{4}/, '').replace(/\s\([\s\w]+\)/, ''));</script><noscript>%s</noscript>''' % (
mktime(value.utctimetuple())*1000,
defaultfilters.time(value, arg)
)
return content
def localdatetime(value, arg1=None, arg2=None):
from django.conf import settings
from django.template import defaultfilters

return ''
if arg1 is None:
arg1 = settings.DATE_FORMAT

arg2 = settings.TIME_FORMAT

mktime(value.utctimetuple())*1000,
defaultfilters.date(value, arg1),
defaultfilters.time(value, arg2)
)
return content
register = webapp.template.create_template_register()
register.filter(localdate)
register.filter(localtime)
register.filter(localdatetime)
# ./main.py (Request handler)
from google.appengine.ext import webapp
from google.appengine.ext.webapp import template
def main():
webapp.template.register_template_library('utils.localdatetimefilters')

So many equal rows in code! What about DRY principle?
