DEBUG = False causing 500 errors and unable to force logging everything to console in Django
I am trying to troubleshoot a 500 error, as whenever I set DEBUG = False in Django, I receive a 500 error. I attempted to set ALLOWED_HOSTS = ['*'] I attempted to setup LOGGING to debug and force logging to console with a loop. However, it does not work, so there is a good chance it is not doing what I think it should be doing.

Strange server outages when using Django Channels
I’m trying to write multiplayer chat using Django Channels. I followed the tutorial on https://channels.readthedocs.io/en/latest/index.html. Everything works okey on my local server, I continued with deploying but then I got some strange bug. When I tried to test to chat with other users with the help of my friends programmers (on real server), I ran into this thing: sometimes(!) when there are more than 8-9 users, messages stop coming back: they reach server, being saved the Database, being send to channels, BUT actually do not come from channels back to consumers and that’s why aren’t sent back to users of the chat! I have no idea what to do :(( Could anybody please help me with this? -
Attach A ReportLab Pdf To A Model
After logging in, my users complete a four forms and a pdf is generated containing the data from the forms. I can successfully do this and save the pdf, but dont know how to attach the generated pdf to the user. I usually save form data in an if request.method == 'POST': statement in the view.py file, but the pdf isnt being sent through POST, it is instead generated and saved within a function called after if request.method == 'POST': so I guess i need a way to attach it to the users pdf model within that function? Also, the questionnaire is quite large so I broke it into four separate forms and four seperate models each with a one-to-one relationship with the user. Is this good practice or should I create one large model and break it up using four separate forms? utils.py def generate_questionnaire_pdf(request): # get user user = request.user # create pdf pdf = SimpleDocTemplate(settings.MEDIA_ROOT+'\pdfs\\questionnaire_pdfs\\user_%s.pdf' %user.id) [..cont..] pdf.build(elems, onFirstPage=partial(pageSetup, title=title, user=user), onLaterPages=pageSetup) form.py class QuestionnairePdfForm(forms.ModelForm): class Meta: model = QuestionnairePdf fields = ['questionnaire_pdf'] model.py class QuestionnairePdf(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) questionnaire_pdf = models.FileField(upload_to='pdfs\\questionnaire_pdfs') view.py def final_question(request): if request.method == 'POST': form = FinalQuestionForm(request.POST, request.FILES, instance=request.user.finalquestion) if form.is_valid(): … -

My django app font from Digital Ocean spaces are not working
I have a django app on a live server, the static files are hosted on Digital Ocean spaces. The static files are working well but the fonts are not.

I even embedded the @font-face rule in the html template and connected the font files with the django static files template url but its still not working.
