Question

我将在下面发布我的模型，但请注意我到处都使用'u'前缀，并且我添加了魔术编码行作为我文件的第二行。我正在使用django 1.9和python 2.7

MODEL

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from django.db import models
from django.utils.translation import ugettext_lazy as _

class Organisaatio(models.Model):
    organisaation_nimi = models.CharField(
        verbose_name=_(u"Organisaation nimi"),
        max_length=128,
        null=True,
        blank=True,
        help_text=_(u"Organisaatiosi nimi"),
        )

    organisaation_koko = models.IntegerField(
        verbose_name=_(u"Organisaation Koko"),
        null=True,
        blank=True,
        help_text=_(u"Arvio organisaatiosi jäsenmaräästä"),
        )

    kuvaus = models.TextField(
        verbose_name=_(u"Tehtävän kuvaus"),
        blank=True,
        default="",
        help_text=_(u"Kuvaile tehtävää"),
        )

    kesto = models.DecimalField(
        verbose_name=_(u"Tehtävään käytetty aika"),
        max_digits = 3,
        decimal_places=2,
        null=True,
        help_text=_(u"Arvioi tunneissa, kuinka kauan tehtävään käytetään keskimäärin aikaa"),
        )

    kertaa = models.IntegerField(
        verbose_name=_(u"Kertaa per kuukausi"),
        null=True,
        blank=True,
        help_text=_(u"Arvioi kuinka monta kertaa kuukauden aikana tehtävä tehdään")
        )


    def __unicode__(self):
        return self.organisaation_nimi

运行makemigrations命令后，它开始创建make文件：

 Migrations for 'app':
  0002_auto_20170809_1628.py:
    - Create model Kysymys
    - Add field kertaa to organisaatio
    - Add field kesto to organisaatio
    - Add field kuvaus to organisaatio
    - Alter field organisaation_koko on organisaatio
    - Alter field organisaation_nimi on organisaatio

然后吐出一个unicode错误：

django.utils.encoding.DjangoUnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 21: ordinal not in range(128). You passed in 
<django.utils.functional.__proxy__ object at 0x109ba0ad0> (<class 
'django.utils.functional.__proxy__'>)

我很困惑，因为我已经断言文件顶部的编码，而且我在任何地方都使用了u前缀。

谢谢你的时间！

Answer 1

尝试更换你的＆＃39; ...＆＃39;与b＆＃39; ...＆＃39;

我使用django自动创建我的迁移（使用makemigrations），它往往默认为此。

运行makemigrations时出现DjangoUnicodeDecodeError
