问题描述
我具有以下输入
"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA7YAAAISCAIAAAB3YsSDAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAA5JxJREFUeNrsnQl4FEX6xqcJJEAS7ivhBkMAQTSJ4h0QEQ+I90rAc1cOL3QBXXV1AV1dVwmrsCqQ9VwJ6HoC7oon0T8iEkABwRC5IeE+kkAIkPT/nfmSmprunskk5CDw/p55hu7qOr76api8........"
我想将此文件保存在文件字段中。我该怎么办?
I want to save this file in file field. What can I do?
models.py
class SomeModel(models.Model):
file = models.FileField(upload_to=get_upload_report)
created = models.DateTimeField(auto_now_add=True)
modified = models.DateTimeField(auto_now=True)
我正在尝试这样做
def get_file(data):
from django.core.files import File
return File(data)
并将返回文件保存到模型实例
and save return file to model instance
somemodel.file = get_file(image_base64_data)
但它会出现以下错误
AttributeError at /someurl/
'File' object has no attribute 'decode'
推荐答案
import base64
from django.core.files.base import ContentFile
format, imgstr = data.split(';base64,')
ext = format.split('/')[-1]
data = ContentFile(base64.b64decode(imgstr), name='temp.' + ext) # You can save this as file instance.
使用此代码段解码base64字符串。
Use this code snippet to decode the base64 string.
