python - Redisco ListField unicode 保存错误但验证为真

Question

class Article(models.Model):
       title = models.Attribute()
       tags = models.ListField(unicode)

 new = Article(title='what ever')
 new.tags = [ u'Niña', u'Niñb' ]

 new.is_validate()
 >>> True

 new.save()

加载时:

Article.objects.all()

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 0: ordinal not in range(128)

在 redis-cli 中:

redis 127.0.0.1:6379> GET "Article:tags:5omv5reh"
(error) ERR Operation against a key holding the wrong kind of value

那么是什么原因造成的呢？

Answer 1

所以经过尝试，unicode字符串应该总是被编码并保存为字符串。 get时总是decode。代码来了:

class Article(models.Model):
       title = models.Attribute()
       tags = models.ListField(str)

 new = Article(title='what ever')
 new.tags = [ u'Niña'.encode('utf-8'), u'Niñb'.encode('utf-8') ]

 new.is_validate()
 >>> True

 new.save()

打印时:

 articles = Article.objects.all()
 for i in articles:
     print i.decode('utf-8')
