I am trying to save the base64 encoded image in the django rest framework. First of all, we make a code to insert the base64 encoded image into the imagefield and test it, and the following error appears.
binascii.Error: Incorrect padding
What I don't understand is that I've used the same code before and there was no such error. Can you help me? Here is my code.
serializers.py
from rest_framework import serializers
from .models import post, comment
class Base64ImageField (serializers.ImageField) :
def to_internal_value (self, data) :
from django.core.files.base import ContentFile
import base64
import six
import uuid
if isinstance(data, six.string_types):
if 'data:' in data and ';base64,' in data :
header, data = data.split(';base64,')
try :
decoded_file = base64.b64decode(data)
except TypeError :
self.fail('invalid_image')
file_name = str(uuid.uuid4())[:12]
file_extension = self.get_file_extension(file_name, decoded_file)
complete_file_name = "%s.%s" % (file_name, file_extension, )
data = ContentFile(decoded_file, name=complete_file_name)
return super(Base64ImageField, self).to_internal_value(data)
def get_file_extension (self, file_name, decoded_file) :
import imghdr
extension = imghdr.what(file_name, decoded_file)
extension = "jpg" if extension == "jpeg" else extension
return extension
class commentSerializer (serializers.ModelSerializer) :
class Meta :
model = comment
fields = '__all__'
class postSerializer (serializers.ModelSerializer) :
author = serializers.CharField(source='author.username', read_only=True)
image1 = Base64ImageField(use_url=True)
image2 = Base64ImageField(use_url=True)
image3 = Base64ImageField(use_url=True)
image4 = Base64ImageField(use_url=True)
image5 = Base64ImageField(use_url=True)
comment = commentSerializer(many=True, read_only=True)
class Meta:
model = post
fields = ['pk', 'author', 'title', 'text', 'image1', 'image2', 'image3', 'image4', 'image5', 'tag1', 'tag2', 'tag3', 'tag4', 'tag5', 'comment']
