Django 1.5 UnicodeEncodeError在電子郵件中使用attach_alternative

Question

我正在將Django項目從1.3遷移到1.5。

發送電子郵件的一個應用程序現在在我的開發機器中不能工作。我得到這個錯誤：

UnicodeEncodeError在/ envia_activacion/ 'ASCII' 編解碼器無法編碼的字符的u '\ XF3' 在位置37：在範圍序數不（128）

Exception Type: UnicodeEncodeError at /envia_activacion/ 
Exception Value: 'ascii' codec can't encode character u'\xf3' in position 37: ordinal not in range(128) 

我的代碼是這個：

plaintext = get_template('emailing/activacion.txt') 
htmly = get_template('emailing/activacion.html') //html template with utf-8 charset 
d = Context({ 
    'code': code, 
    'version': sVersion, 
    'activacion': activacion, 
    'distribuidor': distribuidor, 
    'contacto': contacto, 
    'departamento': departamento, 
    'empresa': empresa 
      }) 

asunto = u'Código activación %s - V%s - Code: %s' % (nombre_destinatario, version, code) 
text_content = plaintext.render(d) 
html_content = htmly.render(d) 

msg = EmailMultiAlternatives(asunto, text_content, remitente, para, [remitente], headers={'Reply-To': remitente}) 
msg.attach_alternative(html_content, "text/html")//This is what makes it fail 

msg.send() 

這在django 1.3中工作，不知道在django 1.4。

調試，我看到失敗的文本是unicode：

> /usr/lib/python2.6/email/generator.py(178)_handle_text() 
-> self._fp.write(payload) 
(Pdb) s 
UnicodeEncodeError: UnicodeE...ge(128)') 
> /usr/lib/python2.6/email/generator.py(178)_handle_text() 
-> self._fp.write(payload) 
(Pdb) payload 
u'Apreciado cliente, le indicamos los c\xf3digos necesarios ...' 

我使用python 2.6.5。我已經查看了這個票看起來幾乎相同https://code.djangoproject.com/ticket/19107，但在Django 1.5補丁已經存在，我仍然得到這個錯誤。

我真的很感激任何幫助。謝謝

你的負載是一個unicode實例（注意，Django努力在內部只使用unicode），而它應該是str實例。這是您通過（最好是正確編碼）str的責任。這很容易FWIW：

# I assume you use utf-8 everywhere 
text_content = plaintext.render(d).encode("utf-8") 
html_content = htmly.render(d).encode("utf-8")
