Question

我的mongodb使用utf-8，而django从中读取的数据不是unicode，也许是答案，但如何解决这个问题呢？

mongodb中的数据有一些中文。如果我使用另一个完全由字母或数字组成的表格，它将会很好用。

class Source(Document) :
    id              = IntField()
    url             = StringField()
    fetchTime       = StringField()
    domain          = StringField()
    xml_tpl_old     = StringField()
    xml_tpl_new     = StringField()
    source          = BinaryField()
    xmlResult       = StringField()
    xmlResult1      = StringField()

如果我使用源表（它有一些中文数据）

Source.objects.all()

django会给出消息


Traceback (most recent call last):
  File "E:/Django_project/mysite/mysite/test.py", line 49, in 
    unicode(Source.objects)

谢谢！

Answer 1

在你的python控制台中试试这个

>>>import sys
>>>sys.getdefaultencoding()

如果结果为＆＃39; ascii＆＃39;，则应更改默认编码。

Answer 2

在将数据保存到数据库之前，我使用base64编码。

mongoengine django和编码，'utf8'编解码器无法解码字节
