Question

如何只显示他们上传的用户文件（不是全部）我使用的是python 2.7和django 1.7和django allauth。以下是我的模特。如果有人能指出我正确的方向，谢谢你。

models.py

def hashed_uploads_dirs(instance, filename):
    return os.path.join(instance.md5, filename)

class File(models.Model):
    f = models.FileField(upload_to='.')
    md5 = models.CharField(max_length=32)
    created_at = models.DateTimeField(auto_now_add=True)
    def was_published_recently(self):
        return self.created_at >= timezone.now() - datetime.timedelta(days=1)
    was_published_recently.admin_order_field = 'created_at'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

    def __unicode__(self):
        return self.f.name

    @models.permalink
    def get_absolute_url(self):
        return ('file-add', )

def save(self, *args, **kwargs):
    self.slug = self.file.name
    super(File, self).save(*args, **kwargs)



def delete(self, *args, **kwargs):
    """delete -- Remove to leave file."""
    self.file.delete(False)
    super(File, self).delete(*args, **kwargs)

Answer 1

您需要修改文件类以将外键存储到用户。它应该看起来像

...
from django.contrib.auth.models import User
class File(models.Model):
    f = models.FileField(upload_to='.')
    md5 = models.CharField(max_length=32)
    created_at = models.DateTimeField(auto_now_add=True)
    user = models.ForeignKey(User, related_name='uploaded_files')
...

上传文件时，您还必须在保存文件之前设置用户。然后，当您拥有User实例时，您可以使用user.uploaded_files获取所有上传的文件。

在文件中创建一个新字段：user = models.ForeignKey(User)

然后你可以做

file.user = request.user
file.save()

在处理文件上传的函数
