示例1: index
# 需要导入模块: from eulexistdb.query import QuerySet [as 别名]
# 或者: from eulexistdb.query.QuerySet import only [as 别名]
def index(request):
qs = QuerySet(using=ExistDB(), xpath='/tei:TEI', collection='docker/texts/', model=RocheTEI)
# Make titles unique (maybe there is a better method?)
qs = qs.filter(chapter='1')
qs = qs.only('title', 'title_en', 'author')
return render_to_response('browser/index.html', {'tei_documents': qs}, context_instance=RequestContext(request))示例2: ExistQueryTest
# 需要导入模块: from eulexistdb.query import QuerySet [as 别名]
# 或者: from eulexistdb.query.QuerySet import only [as 别名]
