I would like to upload files and images using django-channels but i don't have any idea where to start. Seems like there is not much documentation about websockets and file/image uploads. Any ideas?
I also faced the same problem and I solved it by uploading the the Image/File in S3 bucket. we just need to decode the base64 code and upload the file and return the URL to websocket. We can also provide preview of the image by providing the file type.
def file_upload(self, data):
# Convert decode the base64 data
file = base64.b64decode(data['data']['content'].split(',')[-1])
filename = data['data']['filename']
type = data['data']['type']
AWS_ACCESS_KEY_ID = getattr(settings, "AWS_S3_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = getattr(settings, "AWS_S3_SECRET_ACCESS_KEY")
bucket_name = getattr(settings, "AWS_STORAGE_BUCKET_NAME")
conn = boto.connect_s3(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
bucket = conn.get_bucket(bucket_name)
k = Key(bucket)
k.key = getattr(settings, "AWS_CHAT_DIR") + '/' + filename
k.set_metadata('Content-Type', type)
k.set_contents_from_string(file)
url = 'https://' + getattr(settings, "AWS_BUCKET_URL") + '/' + k.key
message = url
content = {
'command': 'new_message',
'message': self.message_to_json(message)
}
return self.send_chat_message(content)
