How to Save io.BytesIO pdfrw PDF into Django FileField
What I am trying to do is basically: Get PDF from URL Modify it via pdfrw Store it in memory as a BytesIO obj Upload it into a Django FileField via Model.objects.create(form=pdf_file) My issue is that when the create() method runs, it saves all of the fields except for the form. helpers.py import io import tempfile from contextlib import contextmanager import requests import pdfrw @contextmanager def as_file(url): with tempfile.NamedTemporaryFile(suffix='.pdf') as tfile: tfile.write(requests.get(url).content) tfile.flush() yield tfile.name def write_fillable_pdf(input_pdf_path, output_pdf_path, data_dict): template_pdf = pdfrw.PdfReader(input_pdf_path) ## PDF is modified here buf = io.BytesIO() print(buf.getbuffer().nbytes). # Prints "0"! pdfrw.PdfWriter().write(buf, template_pdf) buf.seek(0) return buf views.py class FormView(View): def get(self, request, *args, **kwargs): form_url = 'http://some-pdf-url.com' with as_file(form_url) as temp_form_path: submitted_form = write_fillable_pdf(temp_form_path, temp_form_path, {"name": "John Doe"}) print(submitted_form.getbuffer().nbytes). # Prints "994782"! FilledPDF.objects.create(form=File(submitted_form), name="Test PDF") return render(request, 'index.html', {}) As you can see, print() gives out two different values as the BytesIO is populated, leading me to believe the increase in size means there is actually data in it. Is there a reason it is not saving properly into my django model instance? -

Really struggling with this one. I have the following config: Django/DRF Boto3 Django-storages I am using an IAM user credentials with one set of keys. I have removed all other sets of keys including root keys from my account, to eliminate keys mismatch. Original bucket name was my-staging-bucket.

Django CheckConstraint: Elements of reverse ForeignKey lookup must not be empty
I've got these models: class Container(models.Model): ... class Meta: constraints = [ models.CheckConstraint(check=~Q(elements=None), name='container_must_have_elements'), ] class Element(models.Model): container = models.ForeignKey(Container), related_name='elements', on_delete=models.CASCADE ) I want to enforce the constraint that every Container object must have at least one Element referencing it via the foreign key relation. As you can see I already added a check constraint. However, the negation operator ~ on the Q object seems to be forbidden. I get django.db.utils.NotSupportedError: cannot use subquery in check constraint when I try to apply the generated migration. Without the negation operator the constraint seems to be valid (it only fails due to a data integrity error). Is there another way I can express this constraint so it is supported by CheckConstraint? (E.g. is there a way to check if the set of elements is not empty?) -
NoReverseMatch at /login - error with LOGIN_URL or reverse function?

I have a registration.html and a login.html templates inside path: templates > authentication Everything, including the registering function, works fine, but as I try to access to login template, the browser returns: NoReverseMatch at /login 'app' is not a registered namespace I bet the problem lies in the LOGIN_URL that I added in settings.py to enable authentication system (I am following a tutorial).

Making Django migrations backwards compatible with SQL-Server
We have a Django application that previously only used Postgres as its DB backend. Now a client would like to use the application with MS SQL-Server. Previously, a developer added a unique constraint on a text field. It's a small table, so the index doesn't overwhelm things, and of course Postgres thinks this is fine, so testing didn't detect any problems. We have an existing release (several releases back, in fact), that includes a migration to add that constraint. Let's say this was called app/migrations/0002_add_unique.py Now we get the request for SQL-Server compatibility. We added a site configuration option to let an installer specify the DB engine as well as the connect string, so you can pick MS SQL-Server rather than Postgres, but of course migrations breaks when it tries to create the database in SQL-Server. Migrations has to run in the correct order, so SQL-Server blows up trying to add the illegal constraint before it gets to the migration that either removes the constraint or changes the text field to a long varchar. We solved this in the current release candidate by modifying the old 0002_add_unique.py migration so that it doesn't add the uniqueness constraint. There is also a … -

Django - Cannot test request as authenticated user with django-allauth
I have a new django project (2.2), a custom user model and django-allauth to manage user registration (not via social, just with the email confirmation) and I'm trying to test some protected views. In the setUp method of the test I create a new user and create a new EmailAddress (from allauth.account.models) with verified and primary set to True. Next I try to login with: self.client.login(username=username, password=password) and I get True so everything is working so far and the user is logged. Now if I try to get any views that requires login I always get a 301 redirect to the login page! I looked around but didn't find a solution to my problem so far. Let me show you some code: user creation in setUp username = 'test@test.com' password = 'testtesttest' new_user = User.objects.create_user( username=username, email=username, password=password, ) new_user.save() new_user.is_active = True new_user.save() new_email_address = EmailAddress( user_id=new_user.id, email=username, verified=True, primary=True, ) new_email_address.save() login and test logged in logged_in = self.client.login(email=username, password=password) self.assertTrue(logged_in) # and this works as expected Now if I try to request a view that requires login: response = self.client.get("/protected") I get <HttpResponsePermanentRedirect status_code=301, "text/html; charset=utf-8", url="/protected/"> What am I doin't wrong?
