django - dynamic FilePathField question

Question

I have a model where the location of pdf directory I'm pointing to with my FilePathField is based on the "client" and "job_number" fields.

class CCEntry(models.Model):
    client = models.CharField(default="C_Comm", max_length=64)
    job_number = models.CharField(max_length=30, unique=False, blank=False, null=False)
    filename = models.CharField(max_length=64, unique=False, blank=True, null=True)
    pdf = models.FilePathField(path="site_media/jobs/%s %s", match=".*.pdf$", recursive=True

    @property
    def pdf(self):
            return "site_media/jobs/%s %s" % (self.client, self.job_number)

    def __unicode__ (self):
            return u'%s %s' % (self.client, self.filename)

    class Admin: 
            pass

I've tried to pass the client and job_number data to the pdf field dynamically by using a @property method on the model class, but either my approach or my syntax is fualty because the entire pdf field disappears in the admin. Any pointers on what I'm doing wrong?

Based on your subsequent post on similar functionality in the FileField (see last link below) And my inability to get any of the above to work, I'm gonna hazard a guess that it's not yet possible for the FilePathField field type.

I know that passing a callable works for most fields' 'default' parameters... https://docs.djangoproject.com/en/dev/ref/models/fields/#default ... as it appears to work for the upload_to param of FieldField (eg https://stackoverflow.com/questions/10643889/dynamic-upload-field-arguments/ ) andImageField` (eg Django - passing extra arguments into upload_to callable function )

Anyone interested in extending FilePathField to include this feature?
