我正在使用django 1.5.11 for mongodb。 Serializer.data为listfield中给出的所有引用返回对象而不是id。 我以json格式发布数据，如下所示：
{
"author_id": ["5874a85b58c1d23a5343cc87","5874a85058c1d23a5343cc86"],
"title":"my book1"
}
print serializer.data给出：
{'author_id': [<Authors: Authors object>, <Authors: Authors object>], 'Cost': None, 'id': u'5874c75a58c1d23ec8adf40f', 'title': u'my book1'}
我期待serializer.data为：
{'id': u'5874c75a58c1d23ec8adf40f', u'author_id': [u'5874a85b58c1d23a5343cc87', u'5874a85058c1d23a5343cc86'], u'title': u'my book1'}
