Django的图像上载不能上传日本命名的图像

Question

上传日本命名的图像时我收到的错误是：在45-48位置ASCII”编解码器无法编码的字符：在范围内（128）

序数不以英文字符命名时，图片可以完美上传。此外，奇怪的是，我遇到的错误只是当我上传到服务器。日文命名不会在部署服务器上传，但在开发过程中工作正常。

我的模型：

class Tenant_Post(models.Model): 
    user = models.ForeignKey(User,on_delete=models.CASCADE,null=True) 
    name = models.CharField(max_length=255,null=True) 
    image = models.FileField(upload_to='image/tenant/',null=True) 
    posted_on = models.DateTimeField(auto_now_add=True, auto_now=False) 
    last_modified_on = models.DateTimeField(auto_now_add=False, 
    auto_now=True) 

    def __unicode__(self): 
     return self.name 

我的观点：

@login_required(login_url='/') 
def new(request): 
    if request.method == 'POST': 
     print request.POST 
     form = TenantForm(request.POST or None, request.FILES or None) 
     if form.is_valid(): 
      instance = form.save(commit=False) 
      instance.user = request.user 
      instance.save() 
      print 'success' 
      return HttpResponseRedirect(reverse('tenant:all')) 
     else: 
      print 'fail' 
      return render(request,'tenant/new.html',{'form':form,}) 
    else: 
     form = TenantForm() 
     return render(request,'tenant/new.html',{'form':form,})

Answer 1

我还没有与日本语言测试，但它与其他一些语言就像葡萄牙的特殊人物：

添加这对您的settings.py

DEFAULT_FILE_STORAGE = 'app.models.ASCIIFileSystemStorage' 

而且你app.models.ASCIIFileSystemStorage

# This Python file uses the following encoding: utf-8 
from django.db import models 
from django.core.files.storage import FileSystemStorage 
import unicodedata 

class ASCIIFileSystemStorage(FileSystemStorage): 
    """ 
    Convert unicode characters in name to ASCII characters. 
    """ 
    def get_valid_name(self, name): 
     name = unicodedata.normalize('NFKD', name).encode('ascii', 'ignore') 
     return super(ASCIIFileSystemStorage, self).get_valid_name(name) 

Answer 2

加编码UTF-8则可以接受大多数语言 也到模板html使用字符集utf-8

# -*- coding: UTF-8 -*- in at the top the file 

<meta charset="utf-8"/> in html templates 

编辑： 请阅读官方文档或添加此行

from __future__ import unicode_literals

Answer 3

你的错误是由os.stat(path)通话，这意味着你的文件系统不支持日文字符（实际上它可能只支持ASCII或一些拉丁-XXX或凸起windows-yyy编码）。

这里主要有两种解决方法：要么将系统配置为在任何地方使用utf-8（无论如何IMVHO都是一个理智的事情），要么确保只对文件系统使用系统编码（或者简单的ascii）名字等（参见leeeandroo的回答）。
