[英]Error when uploading an image to ImageField via Django Admin
Trying to upload a picture via the Django admin panel and I'm getting an error. 尝试通过Django管理面板上传图片,但出现错误。 The model is:
该模型是:
fs = FileSystemStorage(location='/media')
class Picture(models.Model):
picture_path = models.ImageField(upload_to=fs, blank=True)
hunter_ID = models.ForeignKey(User,
on_delete=models.CASCADE,)
bounty_ID = models.ForeignKey('bountyhunt.Bounty',
on_delete=models.CASCADE,)
winner = models.BooleanField(default=False)
example_pic = models.BooleanField(default=False)
def __str__(self):
return self.picture_path
and the error I'm getting is: 我得到的错误是:
TypeError at /admin/hunt/picture/add/
__str__ returned non-string (type ImageFieldFile)
Request Method: POST

Any ideas? 有任何想法吗?
As the error indicates, the issue id with your Picture
model's __str__
method. 如错误所示,
Picture
模型的__str__
方法的问题ID。 Instead of returning a string it is returning an ImageFieldFile
object. 而不是返回字符串,而是返回
ImageFieldFile
对象。
Change it to return a string - eg, 更改它以返回字符串-例如,
def __str__(self):
return str(self.picture_path)
or: 要么:
def __str__(self):
return self.picture_path.name
