Best way to use ProxyPass to replace certain pages of static site
I have a legacy static site that I host on apache. Over time I have needed to add dynamic features to that site so I installed Django and configured it via WSGIDaemonProcess but my understanding was that it would need to be in a subfolder (ie. /django-stuff/*). But now there are some legacy pages (ie. /legacy-important-page.html) that were in the root folder that I would like to replace with a dynamic route. I know that I can use ProxyPass to reroute a single url (ie. ProxyPass "/legacy-important-page.html" "https://www.example.com/django-stuff/legacy-important-page") or use a redirect. But is there a way to have Apache configured to check if a static file exists, otherwise use a dynamic route? Or another way to accomplish what I'm looking for? If there is another web server that accomplishes it I would be open to that as well. -
How to set StaticLiveServerTestCase to work with websockets
I am currently creating a test using behave and StaticLiveServerTestCase to spin up a runserver, and for some reason I can't connect to my websocket url I am not sure if channels are supported in StaticLiveServerTestCase and if there is a manual way to do this.

How to call function in another python project from django views?
I have a python project which will open connection, and will update database forever until connection is closed (will run in infinite loop as long as connection is alive). Now this has to be initialized from django views once the user lets say clicks start in the UI. It works perfect if I just import those functions in the views. But the problem is if django is stopped it destroys all the objects as well meaning it stops background database update work as well. How make the background work independent of django but the initialization should happen from UI ? Flow is like this : Start the Django Server Ask User to Initiate by clicking start button Call the function which will run forever to update database (independent of django server) Even django is closed background update should happen Help me to solve the above problem.

Nginx Bad Request (400) only with domain name not with IP (gunicorn and django)

Behave failed on websocket test
I am currently working on test with behave, everything is working as intended but when I try to connect to a websocket I can't seem to connect and it returns 404. I have read at [https://github.com/behave/behave-django/issues/16][1] that I have to set up a channel backend.

Problem listing out 3rd level of data from my models effectively (Django)
I need to create a monitoring/summary view for the last 7 days of assurance data we collect on a daily basis. I have 3 models: Customer Equipment (The Customer's equipment) Stats (Daily data on performance, i.e. uptime percentage) In the views I'm filtering out the active customers and passing this to the template based on active equipment (remotes), and I'm also passing on the calculated date range (today's date -7 days). In the view I was easily able to list out the customer (name, parent's name) and the equipment data (serial number, installation date). But for the next level I'm really banging by head against the wall how to retrieve the Stats (uptime percentage) based on date and serial number of the equipment without some ugly nested for loops that runs the same query multiple times and makes the load take very long. The solution so far: for remote in remotes</br> # remotes bassed from the view <tr> <td>{{remote.parent}}</td> <td>{{remote.serial}}</td> <td>{{remote.install_date}}</td> for date in dates # dates passed from the view for stat in remote.stat_set.all|dictsortreversed:"date"|slice:":8" if date == stat.date: <td>Output the {{stat.percentage}} value</td> endif endfor endfor </tr> endfor I've made a hack with combining django and javascript in the template/html, … -

Django - How to run consecutive forms?
I have a user registration form that asks for user information and also asks a question: "Are you a PSMC member?" The options are: rank = [ ('Supporter', 'Supporter (non-member)'), ('Anak', 'Anak'), ('Uso', 'Uso'), ('Chief', 'Chief'), ] If Supporter is selected, then the registration form proceeds and saves user info, etc. This part works fine. However, if Anak is selected, I want it to take the user to another form that asks additional questions. In my forms.py, I have class RegisterForm which is the main registration form for all users. I also have class AnakRegisterForm which is what I want it to continue on to. I used Django's AuthenticationForm based off what I read from their website (but I could be wrong). I know the issue is in views.py register function. Specifically: if rank == 'Anak': anak_register(response) During my debug session, after it moves response to anak_register function, it gets a bunch of scrambled information. I'm pretty lost, any help would be appreciated. Here is my code: forms.py class RegisterForm(UserCreationForm): email = forms.EmailField( initial='', required=True, help_text='Please enter a valid email address' ) rank = forms.ChoiceField( label='Are you a PSMC member?', choices=SavBlock.models.User.rank, initial=False, required=True, help_text='Member accounts will be validated with your … -

I realize that this question has been asked before, but I'm struggling for explanation as to why I'm getting the following error: ValueError: The view django.contrib.auth.logout didn't return an HttpResponse object. It returned None instead. I'm following exactly what Django has in their docs here when it comes to logging out: https://docs.djangoproject.com/en/3.2/topics/auth/default/#how-to-log-a-user-out class LoginPage(TemplateView): template_name = "users/login_page.html" def get_context_data(self, *args, **kwargs): context = super().get_context_data(*args, **kwargs) context['login_form'] = LoginUserForm(data=self.request.POST or None) return context def get(self, request): context = self.get_context_data() return self.render_to_response(context) def post(self, request): context = self.get_context_data() form = context['login_form'] if form.is_valid(): user = form.get_user() login(request, user) return HttpResponseSeeOther(reverse("questions:mainpage")) return self.render_to_response(context) def logout_user(request): logout(reqeust) return HttpResponseSeeOther(reverse("users:login")) user_urls = ([ path("register/", uv.RegisterPage.as_view(), name="register"), path("login/", uv.LoginPage.as_view(), name="login"), path("logout/", uv.logout, name="logout") ], 'users') urlpatterns = [ path('admin/', admin.site.urls), path("", include(question_urls)), path("users/", include(user_urls)), ] -
Serving static images in Django development
this is a commonly asked question so I am not sure why I can't get this to work. Foremost, here is the file structure of my project: -blog -templates - - about.html -media -static - -css - -img - - profile_pic - -js ... I have gone through the process of configuring my settings.py to serve static files during development by adding the following: STATIC_URL = '/static/' and STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static',), ] into my settings.py file. In my about.html, I place the {% load static %} tag at the top of the page, then I attempt to load my image by calling the tag like so: <img class = "card-img-top" src="{% static 'img/profile_pic'%}" alt="My profile picture"> Nothing appears. The logs state "GET /static/img/profile_pic HTTP/1.1" 404 1671 So the file isn't loading at all. Could this be a problem with my filepaths? -
