当尝试将Django模型转换为XML时，UnicodeEncodeError [英] UnicodeEncodeError when trying to convert Django models to XML

问题描述

我发现了一个python程序：导出Django数据库到xml文件，将django模型转换为xml表示。尝试运行程序时会收到这些错误。我的模型包含一些用法语编写的文本。

I found a python program: Export Django database to xml file that converts django models to a xml representation. I get these errors when trying to run the program. My models contain some text written in French.

Traceback (most recent call last):
  File "xml_export.py", line 71, in <module>
  writer.content(value)
File "xml_export.py", line 41, in content
  self.output += str(text)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 3:
ordinal not in range(128) 

推荐答案

看起来您的变量 text 包含一个非ASCII字符串。

It looks like your variable text contains a non-ASCII string.

请参阅：

>>> mystring = u"élève"
>>> mystring
u'\xe9l\xe8ve'
>>> str(mystring)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0: ordinal not in range(128)

所以，您首先需要将您的字符串编码为 UTF-8 ：

So, you first need to encode your string into UTF-8:

>>> str(mystring.encode("utf-8"))
'\xc3\xa9l\xc3\xa8ve'

或者，如果（如评论所示）文本可能包含除字符串之外的其他变量类型，请使用

Or, if (as the comments show) text may contain other variable types besides strings, use

self.output += unicode(mystring).encode("utf-8")
