python - Heroku 上 Django 中的编码错误

Question

我看到一些主题，人们说使用此命令来解决问题

heroku config:add LANG=en_US.UTF-8

我已经这样做了，但仍然遇到编码问题，就像这样

UnicodeEncodeError at /admin/controladoria/orgao/2/

'ascii' codec can't encode character u'\xe7' in position 23: ordinal not in range(128)

如果我尝试运行上面的命令，这就是我得到的......

daniel@daniel-VirtualBox: (dev *) $ heroku config:add LANG=en_US.UTF-8
Setting config vars and restarting rocky-hollows-8072... done, v11
LANG: en_US.UTF-8
daniel@daniel-VirtualBox: (dev *) $ heroku run bash
Running `bash` attached to terminal... up, run.7893
~ $ python
Python 2.7.6 (default, Jan 16 2014, 02:39:37) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.getdefaultencoding()
'ascii'

在我的机器上，编辑了 sitecustomize.py

Python 2.7.5 (default, Mar 11 2014, 21:42:34) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.getdefaultencoding()
'utf-8'

这应该发生吗？我知道如果我将默认编码放入 sitecustomize.py 中，我就不会遇到问题。

这在 Heroku 上应该如何发生？一旦我无法在 Heroku 上更改 sitecustomize，我该如何解决这个问题？

老问题，但我发现了同样的问题。

我的解决方案:我发现我的heroku的python Wax 2.x。

一切都很顺利，因为我告诉 heroku 使用 python 3.x(作为我的开发环境)。

为此，只需在项目的根目录中添加一个 runtime.txt 文件，然后选择正确的运行时:

python-3.4.3

如下所示:https://devcenter.heroku.com/articles/python-runtimes
