Easy way to get base64 for the image to display in the template, eg: <img src="{{ post.get_cover_base64 }}">
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | import os
import base64
def image_as_base64(image_file, format='png'):
"""
:param `image_file` for the complete path of image.
:param `format` is format for image, eg: `png` or `jpg`.
"""
if not os.path.isfile(image_file):
return None
encoded_string = ''
with open(image_file, 'rb') as img_f:
encoded_string = base64.b64encode(img_f.read())
return 'data:image/%s;base64,%s' % (format, encoded_string)
# Example Usage
from django import models
from django.conf import settings
class Post(models.Model):
...
cover = models.ImageField(upload_to='images/%Y/%m/%d')
def get_cover_base64(self):
# settings.MEDIA_ROOT = '/path/to/env/projectname/media'
return image_as_base64(settings.MEDIA_ROOT + self.cover.path)
