我刚刚安装了Python成像库到我的virtualenv。这是我的models.py文件：

 从django.db导入模型
 
 LITERARY_TYPE =（
（'F'，'Fiction'），
（'N'，'Non-ficiton'），
）
 
 class Book（models.Model） 
 name = models.CharField（max_length = 200）
 author = models.CharField（max_length = 200，blank = True，null = True）
 slug = models.SlugField（unique = True） 
 literary_type = models.CharField（max_length = 1，choices = LITERARY_TYPE）
 description = models.TextField（blank = True）
 added = models.DateField（blank = True，null = auto_now_add = True）
 cover = models.ImageField（blank = True，null = True，upload_to ='/ media /'）
 
 def __unicode __（self）：
 return self .name 
  

这是我第一次使用Django中的文件字段。我的 upload_to 参数是否正确？还有其他问题吗？

解决方案

删除upload_to路径中的第一个斜杠，以便它显示为：
upload_to = 'media /'

In my admin I try to upload an image and after clicking save I get this error:

I just installed the Python Imaging Library to my virtualenv. This is my models.py file:

from django.db import models

LITERARY_TYPE = (
    ('F', 'Fiction'),
    ('N', 'Non-ficiton'),
)

class Book(models.Model):
    name        = models.CharField(max_length=200)
    author      = models.CharField(max_length=200,blank=True,null=True)
    slug        = models.SlugField(unique=True)
    literary_type   = models.CharField(max_length=1, choices=LITERARY_TYPE)
    description = models.TextField(blank=True)
    added       = models.DateField(blank=True,null=True,auto_now_add=True)
    cover       = models.ImageField(blank=True,null=True,upload_to='/media/')

    def __unicode__(self):
        return self.name

This is my first time working with file fields in Django. Is my upload_to parameter correct? Is something else the issue?

解决方案

Remove the first slash in your upload_to path so that it reads: upload_to='media/'
