Question

我写了一个视图，将我的文件保存在存储中并保存到数据库中，我想传递文件路径进行下载，但是我遇到了问题。我的查看功能：

def xmlFile(request):
all = request.POST
data = dict(all)
username = User.objects.get(username=request.user)
xml = xmlFirst.dataToXml(data)
with open('web/data/Fuzzy'+ str(username.username)+'1.xml','w') as myfile:
    myfile.write(xml)
    xmlFile = XmlFile(username= username, upload='Fuzzy'+ str(username.username)+'1.xml',filename='Fuzzy'+ str(username.username)+'1.xml')
    xmlFile.save()
xmlLink = XmlFile.objects.first()
a = xmlLink.upload.path
context = {'data':a}
return render(request, 'xmlFile.html', context)

我的设置

MEDIA_URL = '/data/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'data')

我的xmlFile.html模板

<!DOCTYPE html>
<html>
<body>
    <a href="{{MEDIA_URL}}{{data}}" download="FuzzyMirab1.xml">{{data}}</a>
</body>
</html>

和我的模型：

class XmlFile(models.Model):
id = models.AutoField(primary_key=True)
username = models.ForeignKey(User)
filename = models.CharField(max_length=1000, default="")
upload = models.FileField(upload_to="data", default="")

def __unicode__(self):
    return "{}, {}".format(self.username, self.filename)

当我单击它时，它会转到http://localhost:8000/home/yelesee/Desktop/Mirab/Mirab/data/FuzzyMirab1.xml

我该如何解决。

我已经编辑了MEDIA_ROOT ='/ data /' 并在localhost：8000 / data / FuzzyMirab1.xml中发送正确的根目录却说找不到文件

使用文件io加载保存文件
