2 个解决方案
#1
39
from django.core.files import File
user1=User(name='abc')
user1.pic.save('abc.png', File(open('/tmp/pic.png', 'r')))
You will end up with the image abc.png copied into the upload_to directory specified in the ImageField.
最终将图像abc.png复制到ImageField中指定的upload_to目录中。
In this case, the user1.pic.save method will also save the user1 instance. The documentation for saving an ImageField can be found here https://docs.djangoproject.com/en/dev/ref/files/file/
在这种情况下，user1.pic.save方法也将保存user1实例。保存ImageField的文档可以在这里找到https://docs.djangoproject.com/en/dev/ref/files/file/

from django.core.files import File
user1=User(name='abc')
user1.pic.save('abc.png', File(open('/tmp/pic.png', 'rb')))
Please Use 'rb' instead of 'r'. If you are using python3.
请使用'rb'而不是'r'。如果您使用的是python3。
