使用Django将上传文件重命名为admin [英] Rename file on upload to admin using Django

问题描述

当通过admin上传文件时，我在Django 1.6中使用了一个函数来重命名我的文件，但这在Django 1.8中不起作用.有人知道在1.8中是否仍有可能吗?

I have used a function in Django 1.6 to rename my files when they are uploaded through admin, but this does not work in Django 1.8. Anyone know if it is still possible to do this in 1.8?

class Entry(models.Model):

    def path_and_rename(path):
        def wrapper(instance, filename):
            ext = filename.split('.')[-1]
            # get filename
            if instance.pk:
                filename = "%s-%s.%s" % (instance.pub_date.year,instance.issue, ext)
            else:
                # set filename as random strin
                filename = "%s.%s" % (uuid.uuid4(), ext)    
            # return the whole path to the file
            return os.path.join(path, filename)
        return wrapper


    name = models.CharField(max_length=500)
    pub_date = models.DateTimeField()
    issue = models.PositiveIntegerField()  

    pdf = models.FileField(blank=True, upload_to=path_and_rename('uploads/pdf'))

调用函数 upload_file 时，可以在此函数中重命名文件.

When function upload_file gets called, you can rename the file in this function.
