I couldn't play the audios that were uploaded to admin
I created a new class in my model.py file: class Audio(models.Model): ..... audio_object = models.FileField(default='') And I uploaded my audios to my admin page. However, the audios don't play and I right-clicked to a new browser, it shows "Page Not Found" saying "The current path, appname/“/media/nameoftheaudio.mp3”, didn't match any of the URLconf defined in projectname.urls. I reviewed the answers from Django MEDIA_URL and MEDIA_ROOT but it didn't solve my problems. In my urls.py, I already have: from django.conf import settings from django.conf.urls.static import static urlpatterns += staticfiles_urlpatterns() urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) And in my setting.py, I have: STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'assets'), ) MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') Another piece of information is the audios I uploaded to another class work fine! And that is the first class model I created in this project. I can't detect what do I lack for this Audio class. I am using Django 3.0.4 Thank you!! -
Django enclosing substring in string with anchor tags with href attribute
Right now im using regex to search for the substring in a given string then enclosing it in anchor tags with href that is in jinja template pattern = re.compile(rf"({substring})",re.IGNORECASE); anchoredString = mark_safe(re.sub(pattern, "<a href=\"{% url 'url' substring %}\">"+substring+"</a>"),string))) The tags work fine but when I click on the link, it tries to redirect me to the literal "{% url 'url' substring %}" not the "url" path that I defined in my urls.py. Is there a better way of doing this? -
Django/AJAX - New data is not getting rendered after first jQuery AJAX call (i.e. on subsequent calls)
I have tried to set the cache property to false on the AJAX request, but it did absolutely nothing. I am implementing a JS calendar and when you click on any day, it opens a popup overlay that also includes another calendar. This second calendar is opened via ajax, and everything seems to be working on the first call which renders: Then, upon closing the overlay and clicking another date on the calendar, I always get the first overlay, no matter how many times I click. The AJAX call $.ajax( { type:"POST", url: "/teachers/teacherDayAgenda/", data:{ 'event_date': dateClicked }, dataType: 'json', cache: false, success: function( eventData ) { var lessonEvents = []; var lesson = {}; for (var key in eventData) { if (key=="eventDefault") break; lesson = {}; lesson['title'] = "Lesson with "+eventData[key]['teacher_name']; lesson['start'] = formatDate(moment(eventData[key]['timeslot_start']).toDate()); lesson['end'] = formatDate(moment(lesson['start']).add(40, 'm').toDate()); lessonEvents.push(lesson); } console.log(eventData); $('#teacher_schedule').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'agendaDay,listWeek' }, defaultDate: eventData['event0']['click_event_date'], navLinks: true, eventLimit: true, events: lessonEvents }); $("#teacher_schedule .fc-agendaDay-button").trigger("click"); /*$('td').removeClass('AddEventPopup_open'); */ } }); The View: @login_required def teacherDayAgenda(request): """ Ajax request for popup overlay, changes to student schedule, see day agenda of availability of teachers """ if request.method == 'POST': click_event_date = request.POST['event_date'] studentid = … -

Hoe to change the position of pagination on django?

Static properties not changing in Django
I have a website that I am working on and I wanted to change the css a bit to fit the content (change height of a container). However, after applying the changes when I reload my page, the change does not appear in the website. I'm pretty sure I have linked the static files in the right way since not doing so would not render my website as expected. I have tried doing the same changes to a separate copy not linked with django, and it worked. Anyone know whats going wrong? -

Django: Is annotating twice with same lookup a bad practice?
I want to annotate a queryset to filter with this annotation. In some cases, my queryset might already have the annotation set. What happens if I annotate my queryset twice (same lookup, and same values): Does it perform unnecessary jobs on the DB side? Example: queryset = MyModel.objects.annotate(my_annotation=F("some stuff")).filter(my_annotation="some other stuff") # a bit later queryset = MyModel.objects.annotate(my_annotation=F("some stuff")).filter(my_annotation="some other stuff") If yes, how can I check the already annotated lookups without evaluating my queryset? -

Passing request to messages.error in TemplateView Class
I'm replacing my view defs with classes. I first tried a View: class DiscoverView(View): def get(self, request): page_name = 'discover' try: page = Pages.objects.get(name='discover') except (Pages.DoesNotExist, Pages.MultipleObjectsReturned): messages.error(request, 'Page is not configured: ' + page_name) return redirect('MS_Home') context = { 'page': page, } return render(request, 'base/discover.html', context) This worked fine. I next decided to do a TemplateView with an intervening parent class to try to stay dry. class PageView(TemplateView): def get_context_data(self, *args, **kwargs): context = super().get_context_data(**kwargs) page_name = kwargs['page_name'] try: page = Pages.objects.get(name=page_name) except (Pages.DoesNotExist, Pages.MultipleObjectsReturned): messages.error(self.request, 'Page is not configured: ' + page_name) return redirect('MS_Home') context['page'] = page return context class AboutView(PageView): template_name = 'base/about.html' def get_context_data(self, *args, **kwargs): kwargs['page_name'] = 'about' context = super().get_context_data(**kwargs) return context The normal path works. When the exception is thrown, it dies on the message.error: context must be a dict rather than HttpResponseRedirect. If I take out self.request in the messages.error() call, it complains about a missing parameter so I'm pretty sure it doesn't like self.request. How should I pass request to messages.error()? -

Nginx isn't Serving Django Static Files Correctly Because of Trailing Slash
Currently, I have a Django web app being served by Gunicorn. Gunicorn does not serve static file requests so I am using Nginx in front of Gunicorn to serve static file requests. I am able to containerize the app fine with Docker and can successfully serve application requests but Nginx cannot serve the static file requests correctly because Django appends a trailing slash to static file requests. After running the Docker container with Django, Nginx, and Postgres services, I navigate to the home page of the web app and the first request is fine. HTTP Request 200 The rest of the incoming requests after navigating to the home page of the web app are static file requests all with 404 error codes. HTTP Request 404 The 404 error codes indicate that the server cannot find the static files but I can verify that my static files are stored in the correct location and are present. The 404 error codes are happening because Django static file requests append a trailing slash to the request. So, after reading the Nginx documentation, I discovered that Nginx treats all static file requests with trailing slashes as requests for directories and thus searches for an … -
Is sometimes single complicate query worse than two separate query?
I just came into the article on Django that says, when the amount of data is so huge it's better to split it and send them separately. I'm not really sure about this, because as far as I know, DBMS itself is so optimized and the networking is what causes the greatest portion of the latency. Are there really any cases like this? -
Django: Can't redirect to list page after clicking Submit button
Sorry for the long-ass post. I have a problem with my "update_fisher" view. It doesn't redirect to the "list_fishers" view after clicking the "Submit" button.

requests.post from python script to my Django website hosted using Apache giving 403 Forbidden
My Django website is hosted using Apache server. I want to send data using requests.post to my website using a python script on my pc but It is giving 403 forbidden. import json url = "http://54.161.205.225/Project/devicecapture" headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36', 'content-type': 'application/json'} data = { "nb_imsi":"test API", "tmsi1":"test", "tmsi2":"test", "imsi":"test API", "country":"USA", "brand":"Vodafone", "operator":"test", "mcc":"aa", "mnc":"jhj", "lac":"hfhf", "cellIid":"test cell" } response = requests.post(url, data =json.dumps(data),headers=headers) print(response.status_code) I have also given permission to the directory containing the views.py where this request will go. I have gone through many other answers but they didn't help. I have tried the code without json.dumps also but it isn't working with that also. How to resolve this?
