Django rest framework - Base64 image field

fields.py

import base64

from django.core.files.base import ContentFile
from rest_framework import serializers


class Base64ImageField(serializers.ImageField):
    def from_native(self, data):
        if isinstance(data, basestring) and data.startswith('data:image'):
            # base64 encoded image - decode
            format, imgstr = data.split(';base64,')  # format ~= data:image/X,
            ext = format.split('/')[-1]  # guess file extension

            data = ContentFile(base64.b64decode(imgstr), name='temp.' + ext)

        return super(Base64ImageField, self).from_native(data)

Thanks man! Exactly what I needed

How about using uuids for file names? https://gist.github.com/lensraster/24de2ba061989d70ff4e#file-fields-py

from DRF 3.0, from_native is changed to to_internal_value http://www.django-rest-framework.org/topics/3.0-announcement/

What if i want to make the image optional?, if i don't provide the image it gives error "no file is attached"

Hi please explain where do i use this code?

This is my serializers.py
class Image64Serializer(serializers.ModelSerializer):
class Meta:
model = SampleImage64
fields = ('id', 'image64')

This is models.py
class SampleImage64(models.Model):
image64 = models.ImageField(upload_to('images'))

And when I want to fetch that file? I get "http://some-ip/api/users/17/Raw%20content"

Wuau this method is to convert base64 to image, thank you again, you save my day and my life :D

@s2krish Thanks man! Your comment was useful for me!

You can find a more up-to-date (compatible with 3.x) base64 image field in the following Stack Overflow answer.

Django REST Framework upload image: “The submitted data was not a file”

I have made this field optional. I want to pass null value to the field but its showing error

@kevin-brown thanks, man! You save my day!
