I am trying to get the seving_url for a project that uses django-storages with google cloud storage for media files.
I am trying to serve the files with get_serving_url, but I get a silent failure here with no text logged in the exception.
The blobkey generates correctly from what I can see however the image = images.get_serving_url(blobkey, secure_url=True) raises an exception with no error text.
This is what I have done:
#storage_backends.py
class GoogleCloudMediaStorage(GoogleCloudStorage):
"""GoogleCloudStorage suitable for Django's Media files."""
def __init__(self, *args, **kwargs):
if not settings.MEDIA_URL:
raise Exception('MEDIA_URL has not been configured')
kwargs['bucket_name'] = setting('GS_MEDIA_BUCKET_NAME')
super(GoogleCloudMediaStorage, self).__init__(*args, **kwargs)
#this works fine
def url(self, name):
""".url that doesn't call Google."""
return urljoin(settings.MEDIA_URL, name)
#https://programtalk.com/python-examples/google.appengine.api.images.get_serving_url/_
#This does not work yet
def serving_url(self, name):
logging.info('serving url called')
if settings.DEBUG:
return urljoin(settings.MEDIA_URL, name)
else:
# Your app's GCS bucket and any folder structure you have used.
try:
logging.info('trying to get serving_url')
filename = settings.GS_MEDIA_BUCKET_NAME + '/' + name
logging.info(filename)
blobkey = blobstore.create_gs_key('/gs/' + filename)
logging.info('This is a blobkey')
logging.info(blobkey)
image = images.get_serving_url(blobkey, secure_url=True)
return image
except Exception as e:
logging.warn('didnt work')
logging.warn(e)
return urljoin(settings.MEDIA_URL, name)
I have appengine-python-standard installed and I have wrapped my application
#main.py
from antiques_project.wsgi import application
from google.appengine.api import wrap_wsgi_app
app = wrap_wsgi_app(application)
I also have this in my app.yaml
app_engine_apis: true
I have tried to generate the blobkey in different ways (with and without bucket) I have also tried secure_url = False and True So far nothing seems to work
EDIT: Got a traceback in the logs:
