早上好，我非常感谢你的帮助，我开始使用Django，我正在制作一个Web应用程序，允许工作人员通过表单附加他们的文档（文件）。问题是，在按下提交带有附件的表单时，这些文件不会保存，但是Charfield类型的名称和其他字段会正确保存。保存文件的唯一方法是从管理门户附加它们，但其想法是每个用户都从一个用其ID生成的URL进入，该URL将通过电子邮件发送。此外，文件应该保存命名（DSR_“rut”-“name”-“filename（表单标签）"-0-“扩展名），但我仍然无法配置文件名示例的命名。文件，根据表单的标签。
models.py:

class Candidato(models.Model):
   nombre = models.CharField(max_length = 70, null=True, blank=True)
   rut = models.CharField(max_length = 10, primary_key=True)
   correo = models.EmailField(null=True, blank=True)
   centro_de_costo =models.CharField(null=True, blank=True, max_length =30, choices = cc)
   estado = models.IntegerField(null=True, blank=True)
   imagen = models.ImageField(upload_to=upload_directory_name, null=True, blank=True)
   certificado_antecedentes = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   hoja_de_vida_conductor = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   certificado_residencia = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   certificado_afiliacion_afp = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   certificado_afiliacion_salud = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   fotocopia_cedula_identidad = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   fotocopia_licencia_conducir = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   curriculum_vitae = models.FileField(upload_to=upload_directory_name, null=True, blank=True)
   ultimo_finiquito = models.FileField(upload_to=upload_directory_name, null=True, blank=True)`

   class Meta:
       verbose_name="candidato"
       verbose_name_plural="candidatos"

   def __str__(self):
       return self.nombre +" "+ self.rut

The file should be uploaded to upload_directory_name, but as I mentioned in the beginning, I'm     still missing the instance for the file name, based on the Label:

def upload_directory_name(instance, filename):
   ext = filename.split('.')[-1]
   filename = "DSR_%s_%s_0.%s" % (instance.rut, instance.nombre , ext)
   return os.path.join('uploads',filename)
