在上传照片时,使用 django 在服务器上使用唯一文件名重命名照片的最佳方法是什么?我想确保每个名称只使用一次.是否有任何 pinax 应用程序可以做到这一点,也许带有 GUID?
What's the best way to rename photos with a unique filename on the server as they are uploaded, using django? I want to make sure each name is used only once. Are there any pinax apps that can do this, perhaps with GUID?
推荐答案使用 uuid.要将其绑定到您的模型中,请参阅 DjangoFileField upload_to 的文档.
Use uuid. To tie that into your model see Django documentation for FileField upload_to.
例如在您的 models.py 中定义以下函数:
For example in your models.py define the following function:
import uuid import os def get_file_path(instance, filename): ext = filename.split('.')[-1] filename = "%s.%s" % (uuid.uuid4(), ext) return os.path.join('uploads/logos', filename)然后,在定义 FileField/ImageField 时,将 get_file_path 指定为 upload_to 值.
Then, when defining your FileField/ImageField, specify get_file_path as the upload_to value.
file = models.FileField(upload_to=get_file_path, null=True, blank=True, verbose_name=_(u'Contact list'))更多推荐
使用 django 强制执行唯一的上传文件名?
