以編程方式調用call_command（'dumpdata'）後忽略語言設置

Question

我目前以編程方式調用dumpdata以從我的django應用程序中導出數據。

from django.core.management import call_command 
# and various other imports not directly relevant 

response = HttpResponse(mimetype='application/json',) 
response['Content-Disposition'] = "filename=%s" % backup_name 
sys.stdout = response 
call_command('dumpdata') 

出口效果很好（如果稍微慢）但事後settings.LANGUAGE_CODE被忽略，所有的頁面恢復回原來的語言英語。任何想法爲什麼發生這種情況？

我使用了以下內容： - Python 2.7版 - Django的1.3 - 羅塞塔管理語言翻譯

Answer 1

這可能是由代碼在django.core.management.base.BaseCommand對象引起的。在代碼中的解釋是：

# Switch to English, because django-admin.py creates database content 
# like permissions, and those shouldn't contain any translations. 
# But only do this if we can assume we have a working settings file, 
# because django.utils.translation requires settings. 

來完成實際的語言切換是代碼：

from django.utils import translation 
translation.activate('en-us')
