Guarde la imagen base64 en el campo de archivo django

Agradeceríamos tu ayuda para compartir nuestras crónicas acerca de las ciencias informáticas.

Solución:

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.

Utilice este fragmento de código para decodificar base64 string.

import base64
from django.core.files.base import ContentFile

image_data = requestData['user']['image']
format, imgstr = image_data.split(';base64,')
print("format", format)
ext = format.split('/')[-1]

data = ContentFile(base64.b64decode(imgstr))  
file_name = "'myphoto." + ext
user.image.save(file_name, data, save=True) # image is User's model field

es un hilo antiguo, pero esto puede ser útil:

import base64
from django.core.files.base import ContentFile


def base64_file(data, name=None):
    _format, _img_str = data.split(';base64,')
    _name, ext = _format.split('/')
    if not name:
        name = _name.split(":")[-1]
    return ContentFile(base64.b64decode(_img_str), name='.'.format(name, ext))

y puedes usarlo como:

from my_app.models import ImageModel, FileModel

image = ImageModel.objects.create(base64_file(img_base64_str))

# or even base64 files, with custome name
file = FileModel.objects.create(base64_file(data=img_base64_str, name="custome_name"))

y también si necesita archivos codificados en base64 para la prueba, aquí tiene:
