在我的settings.py中添加了以下内容
print(BASE_DIR)
print(MEDIA_URL)
print(MEDIA_ROOT)
打印以下内容
d:/OneDrive/!code_projects/!django_projects/mgTut
/media/
d:/OneDrive/!code_projects/!django_projects/mgTut/media/
但是当我启动服务器时，我看到了这个错误
FileNotFoundError: [Errno 2] No such file or directory: 'd:\\OneDrive\\!code_projects\\!django_projects\\mgTut\\media\\media\\images\\profile_image\\0C0A8604_1_mKlAyCG.JPG'
我不太确定从哪里开始。我的media_root应该被替换，但它似乎不是什么时候被调用。
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR + '/media/').replace('\\', '/')
我的models.py类：
class UserProfile(models.Model):
user = models.OneToOneField(User)
description = models.CharField(max_length=200, default='')
city = models.CharField(max_length=50, default='')
state = models.CharField(max_length=2, default='')
website = models.URLField(default='')
phone = models.IntegerField(default=0)
avatar = models.ImageField(upload_to=b'media/images/profile_image',
default='media/images/profile_image/Profile_Blank.PNG')
avatar_thumbnail = ImageSpecField(source='avatar',
processors=[ResizeToFill(100, 100)],
format='JPEG',
options={'quality': 60})
def __str__(self):
return '%s - %s' % (self.user, self.description)
profile = UserProfile.objects.all()[0]
print(profile.avatar_thumbnail.url) # > /media/CACHE/images/982d5af84cddddfd0fbf70892b4431e4.jpg
print(profile.avatar_thumbnail.width) # > 100

更新：它与ImageKit提供的URL隔离。打印profile.avatar_thumbnail.url就是错误。
尝试添加替换它，同样的问题。
print(profile.avatar_thumbnail.url.replace('\\', '/')) # > /media/CACHE/images/982d5af84cddddfd0fbf70892b4431e4.jpg
print(profile.avatar_thumbnail.width.replace('\\', '/')) # > 100
