Question

我想用Python 2.7和Django 1.7.8构建一个博客。

当我使用Django时，我不断收到错误： UnicodeDecodeError 。相关代码是：

#coding: utf-8
from django.db import models
class Entry(models.Model):
    title = models.CharField(max_length=200)
    body = models.TextField()
    publish = models.BooleanField(default=False)

./manage.py makemigrations 收到错误：

    Migrations for 'blog':
  0001_initial.py:
    - Create model Entry
Traceback (most recent call last):
  File "manage.py", line 10, in <module>

  File "/usr/local/lib/python2.7/dist-packages/Django-1.7.8-py2.7.egg/django/core/management/commands/makemigrations.py", line 143, in write_migration_files
    migrations_directory = os.path.dirname(writer.path)
  File "/usr/local/lib/python2.7/dist-packages/Django-1.7.8-py2.7.egg/django/db/migrations/writer.py", line 222, in path
    return os.path.join(basedir, self.filename)
  File "/usr/lib/python2.7/posixpath.py", line 80, in join
    path += '/' + b
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 10: ordinal not in range(128)

我不知道出了什么问题，任何想法？我已在代码顶部添加 coding:utf-8

Answer 1

你已经在模型中有数据吗？如果是这样，我猜你在那里有一些不好的角色。您是否在模型上定义了 unicode 或 str 方法？如果是这样，我建议在这样的尝试声明中使用它们：

def __str__():
    try:
       return "%s" % self.title
    except:
       return "%s" % self.pk

当您只看到PK时，您会知道您的“标题”字段包含错误的数据。将其扩展为包含您想要显示的字段，而不仅仅是标题。

Answer 2

加入路径时看起来会失败吗？

也许您的文件夹名称无法转换为ascii？

另外，考虑编辑出错的文件？也许在失败的行之前添加一个print语句，显示正在尝试加入的内容？

编辑下面提到的文件，添加print语句以查看尝试加入的内容？

File "/usr/lib/python2.7/posixpath.py", line 80, in join
path += '/' + b
