动态上传字段参数 [英] dynamic upload field arguments

问题描述

如果我有跟踪客户端艺术的基本模型：

if I have basic model for keeping track of client art:

class ArtEntry(models.Model):
    client = models.CharField(max_length=50, choices=CLIENT_CHOICES)
    job_number = models.CharField(max_length=30, unique=False, blank=False, null=False)
    filename = models.CharField(max_length=64, unique=False, blank=False, null=False)
    descriptor = models.CharField(max_length=64, unique=False, blank=True, null=True)
    date = models.DateField(("Date"), default=datetime.date.today)
    post_type = models.CharField(max_length=64, choices=POST_CHOICES)

，此模型的最后一个字段是文件上传字段：

and the last field of this model is a file upload field:

    upload = models.FileField(upload_to='documents/*/**/***')

可以动态填充upload_to参数，以便* =输入'客户端'数据，** =输入'job_number'和 * ='post_t ype'选择？

is it possible to populate the "upload_to" argument dynamically, so that * = the input 'client' data and ** = the input 'job_number' and * = the 'post_type' choice?

推荐答案

当然可以。只需查看 upload_to ：

Sure. Just check the docs for upload_to:

这也可能是一个可调用的，如函数，这将被称为
来获取上传路径，包括文件名。

This may also be a callable, such as a function, which will be called to obtain the upload path, including the filename.
