Python - Convert PDF to HTML through stream instead of path
I am trying to convert a PDF file to HTML by using PDF2HTML: pdf_path = "path\to\pdf_file.pdf" subprocess.run(["pdf2htmlEX.exe",pdf_path]) This works well. However, I would like pdf_path be a Stream instead of a path on my server. My use case is a Django App that lets users upload a PDF file and it converts it to an HTML page without saving anything on a server. I tried converting the uploaded PDF file to a BytesIO and then to a stream and trying to pass that: from PyPDF2 import PdfFileReader, PdfFileWriter # Request.FILES is from the Django Form file_memory = request.FILES # BytesIO file file_handle_file = file_handle.file pdf = PdfFileWriter() pdf_file = PdfFileReader(file_handle_file) page = pdf_file.getPage(0) pdf.addPage(page) pdf.write(open("output.pdf","wb")) subprocess.run(["pdf2htmlEX.exe",pdf]) But this returns a argument of type 'PdfFileWriter' is not iterable error. The pdf.write does write the pdf to storage and if I use subprocess.run to get that file (so using path again), it does work. Also, opening a Stream doesn't work: outputStream = open("test.pdf", "wb") output.write(outputStream) outputStream.close() subprocess.run(["pdf2htmlEX.exe",outputStream]) Is it even possible to pass a pdf file from memory to pdf2htmlEX instead of a path? I've also looked at making it a base64 (base64.b64encode(file_handle_file.getvalue()).decode()), but also to no avail. Many thanks everyone! -

Cannot test many-to-many references in Django
I want to test m2m reference that I've created. In models, it's like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return self.user.username class List(models.Model): name = models.CharField(max_length = 4) user = models.ManyToManyField(Profile) def __str__(self): return f'{self.name} by {self.user.__str__()}' @receiver(post_save, sender = User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user = instance) @receiver(post_save, sender = User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() My test looks as follows: def test_create_list(self): self.create_user("test_user") # returns User.objects.create_user extended_user = Profile.objects.get(pk = 1) l = List.objects.create( name = "2019" ) l.user.add(extended_user) self.assertEqual(l.__str__(), f"2019 by {extended_user.__str__()}") This results in a failed test: Expected :'2019 by hay.Profile.None' Actual :'2019 by test_user' Why this hay.Profile.None comes up?

Deploying Django code (which needs Selenium) to heroku - Python
I have a website made using Django, click a button on the website triggers a scraper to start. This scraper uses selenium. I have added the following two build packs needed for selenium to my heroku app: 1) https://github.com/heroku/heroku-buildpack-chromedriver 2) https://github.com/heroku/heroku-buildpack-google-chrome chrome_options = webdriver.ChromeOptions() chrome_options.binary_location='/app/.apt/usr/bin/google-chrome' os.environ.get("GOOGLE_CHROME_BIN", "chromedriver") browser=webdriver.Chrome(executable_path=os.environ.get("GOOGLE_CHROME_BIN", "chromedriver"),chrome_options=chrome_options) But yet it fails to find the chromedriver and throws the error chromedriver needs to be in PATH, how to fix this issue? Where is the chromedriver executable? -
Testing extended user profile returns false positives in Django
I have an extended user profile, done like this: from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return f'{self.user.username} 123' @receiver(post_save, sender = User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user = instance) @receiver(post_save, sender = User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() And I want to test it: from models import Profile from django.contrib.auth.models import User def test_create_profile(self): base_user = self.create_user("test_user") self.assertTrue(isinstance(base_user, User)) extended_user = Profile.objects.last() self.assertTrue(extended_user.__str__(), "test_user") As you can see, __str__() should return '{self.user.username} 123', so for this example, test_user 123. But, those tests are passing fine. What can I do? -
Want to Pass a Message to the User and Make him redirect to index page on Invalid Login credentials
In Views.py, I've Queried the login credentials of the user who registered on a web page. On Invalid Credentials, He must return to Index page or must be given a url / button to return to index page. Here's the current code that's not working: def user_login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username,password=password) if user: if user.is_active: login(request,user) return HttpResponseRedirect(reverse('index')) else: return HttpResponse('Account Not Active') else: return HttpResponse('Invalid Login Details Supplied!') return HttpResponseRedirect(reverse('index')) else: return render(request,'basicapp/login.html') It's only showing the statement 'Invalid login Details Supplied!' to the user for wrong credentials without changing the webpage link (Link getting unchanged is certain) Can't figure out how to place a button / url in html file in case of such scenarios. Any Hint on Redirect + Message display? A redirect after a few seconds of message display is also fine without a button / url. -

Django-Rest-Framework Custom User not Hashing Password (Serializer Issue)

Django: return messages in form.clean()
Suppose I have a CreateView that uses a ModelForm to add a new calendar event. Sometimes, when adding a new calendar event, another calendar event has to be added before the new event to be able to successfully validate the new event (which happens in the ModelForm.clean() method). I think the only place this other event can be added is in the clean method, just before the validation which validates the new event. Am I right that this is the only place I can do this? I want to let the user know that this happened using Django messages, but of course I don't have access to the request object in the ModelForm. That makes me think I have to add this event in another place. Which method of CreateView is suited for this purpose? I'm sorry in advance for my English and if my question isn't worded good enough. Thanks in advance. -
Websocket related errors when working with Django Rest Framework and Vue
I'm working with Django 2, Django Rest Framework, Vue and Docker on a rather simple CRUD SPA. The basic CRUD functions are already working properly, but I'm constantly getting a long list of errors in the browsers developer console. These are the errors: WebSocket connection to 'ws://localhost:8000/sockjs-node/960/pxv3l3z5/websocket' failed: Error during WebSocket handshake: Unexpected response code: 200 POST http://localhost:8000/sockjs-node/960/mf1pj0yr/xhr_streaming?t=1558372142795 403 (Forbidden) WebSocket connection to 'ws://localhost:8000/sockjs-node/124/3qg4rd5f/websocket' failed: Error during WebSocket handshake: Unexpected response code: 200 EventSource's response has a MIME type ("text/html") that is not "text/event-stream". Aborting the connection. They all seem to be related with a web socket issue, but I'm not actively using websockets. The app just issues a couple of requests to the Django Rest Framework backend. So I really don't know what is causing these errors. Maybe I configured something wrong? -
Use custom UserCreationForm with GeoDjango admin (OSMGeoAdmin)
Django==2.2.1 GDAL==2.3.2 django-username-email==2.2.4 I have a simple Django application with a custom user model based on django-username-email's AbstractCUser, which removes the username from the user model, using e-mail address instead.
