django app listening on localhost:8000 vs 0.0.0.0:8000
I have a Django app running on Google Kubernetes Engine.If I run the enter the pod , and run netstat -l command. It shows that the service is listening on localhost:8000 I ran the same service on Elastic Kubernetes service on AWS. There the service didn't respond to the outside requests when the container was listening on localhost:8000. I had to run python manage.py runserver 0.0.0.0:8000, so that container listens on all the network interfaces. On AWS , the output of netstat -l looks like this I want to understand, that Why the same app was running on the google Kubernetes engine, but not on EKS, and I had to specifically define to listen on 0.0.0.0:8000. Why the google Kubernetes engine listens to outside traffic , when the netstat -l shows that it is listening on localhost:8000 -
Getting error on terminating Django server using Threading and Schedule
I'm trying to use Schedule on the background using threads in my Django application as it was described in Oz123's answer, everything works fine without any problem, except when I'm trying to use commands from the terminal (e.g. python manage.py makemigrations or python manage.py runserver ) they will not end and finished until I'm sending keyboardInterupt. Then it will give me the following error: Traceback (most recent call last): File "/usr/lib/python3.8/threading.py", line 1388, in _shutdown lock.acquire() p.s.: for python manage.py runserver I have to send KeyboardInterupt two times. one for ending the server, then the second one will end the function and raise the mentioned error. My application is using one schedule in the background which is happening every hour to check a model for specific changes. So, there is no stop to this schedule and I want to run it until the server is running (forever). Is there any way to solve this problem? It is so much annoying to press KeyboardInterupt (CTRL + C) for ending every command. -

This is how it was working with my own file system My function to generate a pdf in views.py: def form_render_pdf_view(request, *args, **kwargs): pk = kwargs.get('pk') form = get_object_or_404(Post, pk=pk) template_path = 'form/pdf2.html' context = { 'form': form } # Create a Django response object, and specify content_type as pdf response = HttpResponse(content_type='application/pdf') response['Content-Disposition'] = 'filename="report.pdf"' # find the template and render it. template = get_template(template_path) html = template.render(context) # create a pdf pisa_status = pisa.CreatePDF( html, dest=response) if pisa_status.err: return HttpResponse('We had some errors <pre>' + html + '</pre>') return response And rendering the image in the html template <div> <img src="{{form.image.path}}"> </div> Now after uploading the files in a bucket it doesn't seem to work.

Pass Django Form to js
I am new to django and I want to write an easy Django application with Django 2.3 and Python 3.7. I am using in my view.py (if more of my code is needed, I can provide it): context["form"] = MyForm(request.POST, request.FILES) return render(request, "myhtml.html", context) My forms.py also looks very simple: class MyForm(forms.Form): name = forms.CharField() address = forms.CharField() I want to build in my application a button in which the form appears, but I do not want to hide the form by display: none; Is it possible to give the form over in a format that I can use JavaScript to build the form or do I always need to build the form in HTML and manipulate it afterwards with JS? Is it reasonable to return the Form as JSON.Response or does Django always return the Forms as HTML strings and not JS elements? -

What is the proper python/django way of formatting the URL?
Hello fellow programmers, I am working on a web app for cs50w course and my code is almost fully functional however, I noticed that when I use a specific function the URL not displayed properly.
