Django Storages (GCP) returns NULL if the app is deployed in Cloud Run
I am using Django Storages to upload images on GCP's cloud storage bucket and I accomplished this on localhost by following these steps - Created a private bucket on Cloud Storage. Created a service account with Storage Admin privileges and also generated a JSON key. Installed Django Storages for GCP and Pillow. Created relevant environment variables like GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GS_BUCKET_NAME. Wrote a POST & GET request and it works like a charm on local machine. However, when I deployed this on Cloud Run I am able to upload the images but I get NULL instead of the image's Authenticated URL in response while fetching the image via GET request. As, Cloud Run uses Compute Engine Default Service account So I decided to give it a Cloud Storage Admin permission and then I tried again but still no luck. How can I make this work? -

Django-How can I upload image to a Model, without that field being present in the ModelForm
I am trying to build an image steganography application and for the encoding part I have a form with two fields, one for image and one for the message that is to be encoded. The encoding part takes place in a views.py, but I do not seem to manage how to upload the encoded image in the ImageModel in order to use it later for the decoding part. 1. If I include image_e in the form as a hidden field, I get an error that it needs to be submitted 2. If somehow the form is being submitted, the model contains only the two fields present in the form, 'image' and 'message', and for 'image_e' i get None or the default if i have that option 3. Right now, if I fill the form I get the defaults for all the fields I actually only need 'image_e' stored, but I thought that if I inherit all of the fields from the model it would be easier. I am a beginner in Django and this is my first more complex application. models.py class Image(models.Model): image = models.ImageField(upload_to='images', default='default.png') message = models.CharField(max_length=200, default=1) image_e= models.ImageField(upload_to='encoded', blank=True) forms.py class EncodeForm(forms.ModelForm): #method= forms.CharField(label='How would … -
