Visual Studio Code - Python Interpreter path does not work for me
as i already tried for hours by myself, i could not find out, what i am doing wrong. I am doing the Tutorial of Django on Youtube, which can be found on the following URL: https://www.youtube.com/watch?v=rHux0gMZ3Eg After craeting a virtual environment and starting a project in Virtual Studio Code, he tries to add the python path into the VSCode. In the video he is then able to use Python from the terminal inside the VSCode. However, around minute 19 you can find that in the video. If i do it by myself, nothing is happenning and i am also not able to use Python on the VSCode then. I did not figure out, what i am doing wrong, since i am exactly doing it like in the video. Does anyone have an idea, what i am doing wrong here? Thanks to anyone having an idea. Here are screenshots of what i have done for adding the path. enter image description here enter image description here enter image description here -

Django: why does my custom filter not find an existing item in the array?
I am a beginner in Django. Right now i am working on my first project: reservation of sits for cinema event. The html map of sits is based on the array of cols and rows, provided from the Hall model. There is also an Invoice model, which stores the information about reserved places, based on this event. Based on this, i am trying to disable the html-map checkboxes of the sit places, which are already reserved. Here is my code: views.py def event_map(request, slug, event_id): selected_event = Event.objects.get(pk=event_id) movie = selected_event.film hall = selected_event.hall time = selected_event.get_time_slot_display() date_event = selected_event.get_week_day_display() sits = list(range(0, hall.hall_sits)) cols = list(range(0, hall.hall_cols)) hall_information = generate_hall_information(hall.hall_name) reserved_places = list() invoices = Invoice.objects.all().filter(event=selected_event) for invoice in invoices: reserved_places += invoice.invoice_details.split(',') reservation_form = Reservation() if request.method == 'POST': print(request.POST) form = Reservation(request.POST) if form.is_valid(): post = form.save(commit=False) post.invoice = request.user post.event = selected_event post.save() return render(request, 'pages/event_map.html', { 'movie_name': movie.name, 'hall': hall, 'time': time, 'date': date_event, 'sits': sits, 'cols': cols, 'hall_information': hall_information, 'reservation_form': reservation_form, 'reserved_places': reserved_places, 'test': reserved_places }) event-map.html <div class="theatre-map event-map-grid hall-{{ hall }}" id="theatre-map-target"> {% for sit in sits %} {% if sit|if_in_list:reserved_places %} <label class="res" id="{{ sit }}" disabled=""></label> {% else %} <label … -

django-social-auth redirect to different url based on params
I am using social-auth-app-django to enable OAuth2 from google. My application has two types of users and both are given an option to use google auth. Now after these users register using google, I want to redirect to some page where they add additional information based on the type of user. I am not able to figure out a way how to identify them based on the type of user. I am looking for a way where I can send extra parameter to google and then google return that parameter. This way I can identify the user type. I am simply providing the following in django template. <a href="{% url "social:begin" "google-oauth2" %}"><button>Google</button></a> Edit: One way I am thinking is of having two redirect URL configured in google. Then I can simply add function for these two redirect URL and my problem will be solved. I am not able to figure out how to add that redirect URL in the request to google. -

Form action is not calling the required function from views.py in Django
I am new in Django and doing my first project in it. I had made a form in my index.html file and that form took an image, and sent it to a predictImage function in views.py file. The predictImage function applied YOLO model on the image and returned the image with labels to the same index.html page. This was working fine and I was getting the required results. After the submit button was clicked, I was getting redirected to index.html/predictImage where the results were being shown. (I had conditions added in my index.html to show the results) Then, I decided to add a Users Model and made a Login page for me, user was required to login before he could upload the image. For this, I added sessions as well. Now, I created a Photo model, to store every photo that every user uploads. All of this was successfully made but now, when I tried to do the same thing again, i.e., upload the image and submit it, it didn't work and it instead redirected me to index.html I tried to debug this, and I found out that I was not even going to views.predictImage when I clicked the submit … -

how can i use audio file in pydub through django
Well, i have a code that creates and saves audio and i need to instert in that code a silence cutting system views.py def audio(request): if request.method == 'POST': cu = request.user.customer.pk users = get_object_or_404(Customer, pk=cu) js = get_object_or_404(JsonMap, user_id=users.id) audio = request.FILES['data'] name = audio.name name = name.replace(':', '-') song = Song.objects.create() audio_cut_logic = SoundCutter() song.js = js song.name = name song.audio_file = audio song.save() return render(request, 'action.html', {'file_url': js}) models.py def remove_sil(self, file, format="wav"): sound = AudioSegment.from_file(file, format=format) non_sil_times = detect_nonsilent(sound, min_silence_len=50, silence_thresh=sound.dBFS * 1.5) if len(non_sil_times) > 0: non_sil_times_concat = [non_sil_times[0]] if len(non_sil_times) > 1: for t in non_sil_times[1:]: if t[0] - non_sil_times_concat[-1][-1] < 200: non_sil_times_concat[-1][-1] = t[1] else: non_sil_times_concat.append(t) non_sil_times = [t for t in non_sil_times_concat if t[1] - t[0] > 350] return sound[non_sil_times[0][0]: non_sil_times[-1][1]] i tried to create sound.audio_file through my function song.audio_file = audio_cut_logic.remove_sil(audio) then i tought i need to create that audio file firstly and then use my func song.audio_file = audio song.audio_file = audio_cut_logic.remove_sil(song.audiofile) but all i got is: AttributeError: 'AudioSegment' object has no attribute '_committed'
