我想在我的 django 应用程序中保存和过滤用户的对象。输入以下代码后，图像字段没有将任何图像上传到我的数据库，也没有在我的模板中返回任何图像。

class Fin(models.Model):
user=models.ForeignKey(User)
title=models.CharField(max_length=250, help_text='3 bedroom flat for lease')
main_view=models.ImageField(upload_to="photos",blank=True, null=True)
side_view=models.ImageField(upload_to="photos",blank=True, null=True)
address=models.CharField(max_length=200)
city=models.CharField(max_length=200)
state=models.CharField(max_length=200)
guideline=models.TextField(max_length=1000)
def __unicode__(self):
return self.title
class FinForm(ModelForm):
class Meta:
model=Fin
fields=('title','main_view','side_view', 'address','city','state','guideline')
exclude=('user')

def fincrib(request):
