为什么django使用ascii而不是utf-8? [英] why is django using ascii instead of utf-8?

问题描述

在我的sqlite3数据库中以管理员身份添加数据(具有非ascii字符)时，出现以下错误:

When adding a data (with non ascii characters) as administrator in my sqlite3 database I get the following error :

Exception Type: UnicodeEncodeError at /admin/Project/vin/add/
Exception Value: 'ascii' codec can't encode character u'\xe2' in position 2:        
ordinal not in range(128)

我无法真正找出问题所在，因为在所有不同的设置中它都是用utf-8编写的，而ascii仅出现在错误中.

I can not really figure out what's wrong since it's written utf-8 in all the different settings... and ascii appears only in the error.

我把它作为解释

vin模型

class Vin (models.Model):
    nom_vin =models.CharField (max_length = 20)
    millesime = models.IntegerField() 
    quantity = models.FloatField()
    appelation = models.ForeignKey(Appelation)
    def __str__(self):
        return self.nom_vin

推荐答案

尝试:

class Vin (models.Model):
    nom_vin =models.CharField (max_length = 20)
    millesime = models.IntegerField() 
    quantity = models.FloatField()
    appelation = models.ForeignKey(Appelation)
    def __unicode__(self):                        #You have __str__
        return self.nom_vin
