不能在Django本地化蟒蛇HTMLCalendar

Question

更新：研究了一下這個問題後，（ASCII解決錯誤，但現在返回ValueError異常），我發現，這是一個記錄的缺陷（issue #3067），因此無法解決，直到錯誤解決在Python 2.7.3

我試圖定位在Django和Python HTMLCalendar做了一個日曆，沒有結果。日曆是用code from Elving Uggedal製作的，但似乎無法對其進行本地化。

下面是代碼：

models.py

import calendar 
from datetime import date 
from itertools import groupby 

from django.utils.html import conditional_escape as esc 

class EventCalendar(calendar.LocaleHTMLCalendar): 

    """ 
    Event calendar is a basic calendar made with HTMLCalendar module. 
    """ 

    def __init__(self, events, *args, **kwargs): 
     self.events = self.group_by_day(events) 
     super(EventCalendar, self).__init__(*args, **kwargs) 

    def formatday(self, day, weekday): 
     if day != 0: 
      cssclass = self.cssclasses[weekday] 
      if date.today() == date(self.year, self.month, day): 
       cssclass += ' today' 
      if day in self.events: 
       cssclass += ' filled' 
       body = ['<ul>'] 
       for event in self.events[day]: 
        body.append('<li>') 
        body.append('<a href="%s">' % event.get_absolute_url()) 
        body.append(esc(event.title)) 
        body.append('</a></li>') 
       body.append('<ul>') 
       return self.day_cell(cssclass, '%d %s' % (day, ''.join(body))) 
      return self.day_cell(cssclass, day) 
     return self.day_cell('noday', '&nbsp;') 

    def formatmonth(self, year, month): 
     self.year, self.month = year, month 
     return super(EventCalendar, self).formatmonth(year, month) 

    def group_by_day(self, events): 
     field = lambda event: event.meeting_date.day 
     return dict(
      [(day, list(items)) for day, items in groupby(events, field)] 
     ) 

    def day_cell(self, cssclass, body): 
     return '<td class="%s">%s</td>' % (cssclass, body) 

views.py

from django.shortcuts import render_to_response, get_object_or_404 
from django.utils.safestring import mark_safe 
from django.template import RequestContext 
from django.utils import translation 

from e_cidadania.apps.spaces.models import Meeting, Space 
from e_cidadania.apps.cal.models import EventCalendar 

def calendar(request, space_name, year, month): 

    # Avoid people writing wrong numbers or any program errors. 
    if int(month) not in range(1, 13): 
     return render_to_response('cal/error.html', 
            context_instance=RequestContext(request)) 

    place = get_object_or_404(Space, url=space_name) 
    next_month = int(month) + 1 
    prev_month = int(month) - 1 

    meetings = Meeting.objects.order_by('meeting_date') \ 
           .filter(space = place, 
             meeting_date__year = year, 
             meeting_date__month = month) 

    cur_lang = translation.get_language() 
    print 'DEBUG:LANG: %s' % cur_lang 
    cur_locale = translation.to_locale(cur_lang)+'.UTF-8' #default encoding with django 
    print 'DEBUG:LOCALE: %s' % cur_locale 
    cal = EventCalendar(meetings, settings.FIRST_WEEK_DAY, cur_locale).formatmonth(int(year), int(month)) 

    return render_to_response('cal/calendar.html', 
           {'calendar': mark_safe(cal), 
           'nextmonth': '%02d' % next_month, 
           'prevmonth': '%02d' % prev_month, 
           'get_place': place}, 
           context_instance = RequestContext(request)) 

我使用LocalizeHTMLCalendar嘗試，它應該返回一個本地化的HTMLCalendar ，但使用它作爲基類時，它將在日曆mo中返回一個ASCII解碼錯誤dule（文件中聲明瞭utf-8編碼）。

我也嘗試覆蓋語言環境數組day_name，day_abbr，month_name和month_abbr，這在日曆渲染結束時爲空。

例子：

from django.utils.translation import ugettext_lazy as _ 

calendar.day_name = [_('Monday'), _('Tuesday'), _('Wednesday'), _('Thursday'), _('Friday'), _('Saturday'), _('Sunday'), ] 

我似乎無法找到一種方法來定位這個日曆。有任何想法嗎？

有趣的是，我昨天剛剛做了這個，偶然發現了你的問題。

這裏就是我得到了過去的障礙，不好意思有點複雜：

設置：

LANGUAGE_CODE   = 'en-us' 
FIRST_DAY_OF_WEEK  = 0  # 0 is Sunday 
# Convert to calendar module, where 0 is Monday :/ 
FIRST_DAY_OF_WEEK_CAL = (FIRST_DAY_OF_WEEK - 1) % 7 

# figure locale name 
LOCAL_LANG    = LANGUAGE_CODE.split('-')[0] 
LOCAL_COUNTRY   = LANGUAGE_CODE.split('-')[1].upper() 
LOCALE_NAME    = LOCAL_LANG + '_' + LOCAL_COUNTRY + '.UTF8' 

我認爲這是上面的回答。你使用的是Ubuntu/Debian嗎？除非'.UTF8'在那裏，否則我無法實現它。我還需要下面的utf8 python頭文件。繼續...

觀點：

# -*- coding: utf8 -*- 
class kCalendar(calendar.LocaleHTMLCalendar): 
    def __init__(self, *args): 
     # some customization I did ... 
     calendar.LocaleHTMLCalendar.__init__(self, *args) 
     # super didn't work, can't remember why... 
# more customization here... 

kcal = kCalendar(date, settings.FIRST_DAY_OF_WEEK_CAL, 
    settings.LOCALE_NAME) 
calhtml = kcal.formatmonth(date.year, date.month) 

而且，我需要安裝一些區域設置「包」，因爲我已經吹走用而言localepurge一切。這裏是Ubuntu的腳本：

add_lang_pack.sh：

#!/usr/bin/env bash 

if [ "$#" -eq 0 ]; then 
    echo -e "\nUsage: `basename $0` <locale, eg: en_US>\n" 
    exit 1 
fi 

sudo /usr/share/locales/install-language-pack $1 

if grep -q "$1" /etc/locale.nopurge 
then 
    # code if found 
    echo -e "\n** not adding $1 to /etc/locale.nopurge, is already there.\n" 
else 
    sudo sh -c "echo $1 >> /etc/locale.nopurge" 
    sudo sh -c "echo $1.UTF-8 >> /etc/locale.nopurge" 
fi 

sudo dpkg-reconfigure locales 

希望有所幫助。

這可能是完全不相干的，但在沒有其他想法的情況下，嘗試將

# -*- coding: UTF-8 -*- 

爲你的模塊文件的第一行。
