Add song to Playlist not working Django music App
I'm making a music streaming website (it's my first project on Django). I'm making the view to add a song to a specific playlist, but it is not working (I always get the error "failed to add song to playlist"), and the songs are not added to playlists. How can I fix it? HTML: {% if my_playlists %} <p style="">Add This Song To Your Playlist</p> {% for playlist in my_playlists %} <a class="left-panel-btn" id="D_{{playlist.playlist_id}}" onclick="sendPostRequestPlaylistSong(this)">{{playlist.playlist_name}}</a><br> {% endfor %} {% else %} <p style="">You don't have any Playlist.</p> <a class="create-p" onclick="$('#divId').css({display: 'none'}); document.getElementById('modal-wrapper-playlist').style.display='block'"><i class="fas fa-plus"></i> Create Playlist</a> {% endif %} javascript function: function sendPostRequestPlaylistSong(el) { // alert("Song ID: "+song_id_for_playlist+" | Playlist ID: "+el.id); var data = song_id_for_playlist + "|" + el.id; $.ajax({ "url": "{% url 'music:addSongToPlaylist' %}", "type": "POST", "data": { 'data': data, 'csrfmiddlewaretoken': '{{ csrf_token }}' }, success: function(response) { alert("Song added to your playlist"); location.reload();}, error: function(xhr, status, error) { alert("Failed to add song to playlist.");} }); var div = $("#divId"); div.css({ transition: "0.3s", display: "none" }); } views.py: def addSongToPlaylist(request): user = request.user if request.method == "POST" and user.is_authenticated: data = request.POST['data'] if data: song_id, playlist_id = data.split("|") song_id = song_id[0][2:] playlist_id = playlist_id[1][2:] currPlaylist = Playlist.objects.filter(playlist_id=playlist_id, user=request.user).first() … -
Django+Heroku testing: how to connect to a test database? ('permission denied to create database')
I have been doing my first deployment with django (ever), and I am using Heroku CLI. I get this message when trying to run tests: "Got an error creating the test database: permission denied to create database" I tried first just by running tests. Then I tried to specify the current database as a test option (giving same parameters). I also tried to specify Sqlite as a test database. I am expecting to have a temporal database for testing, or to use the current database for it. I have found an option that creates a custom connection to a postgress database made for only testing purposes. It seems too complicated to be a common problem. I also saw something in heroku pages called dynos database (a temporal one for testing in Ruby), but could not find it in the add ons on the page, nor when trying to do it from the command line (it says its only for command line deployment). Implementing something like what pasted bellow would be ideal as it makes a database temporaly only for testing (found in Ruby section): https://devcenter.heroku.com/articles/heroku-ci-parallel-test-runs { "addons": [ "heroku-postgresql:in-dyno", "heroku-redis:in-dyno" ] } There is an option in NOD.js that looks … -
Complex Django query related to Prefetch, Subquery and OuterRef
I have this queryset below. queryset = Contract.objects.select_related( "company", "user", "user__profile", "user__profile__address", "user__profile__address__living_country", "compensation__currency", "job", "benefit", "payment_details", "working_country", "work_permit", ).prefetch_related( Prefetch( "partner_fee__partner__partner_countries", queryset=CountryPartner.objects.annotate(contract_id=OuterRef("id")).all() ) ) I have to annotate that contract_id to filter that CountryPartner. But it is not possible to use OuterRef there. It always needs Subquery of django.models. Ideally, I want to do this sql query in Django ORM: select cc.id, cc.email, cc.residency_type, dc.country_id from core_contract cc inner join public.core_partnerfee cp on cc.id = cp.contract_id inner join public.core_partnerprofile c on cp.partner_id = c.id inner join public.dicts_countrypartner dc on c.id = dc.partner_profile_id where dc.country_id=cc.working_country_id and dc.residency_type=cc.residency_type and dc.partner_profile_id=c.id order by cc.id; If I use Subquery inside CountryPartner filter it is going to take CountryPartnerId, not Contract ID. See below pls. Prefetch( "partner_fee__partner__partner_countries", queryset=CountryPartner.objects.annotate(contract_id=SubQuery(Contract.objects.filter(id=OuterRef("id")))) ) So, how to be? Django ORM is not able to do this? -

Can't get route to redirect to login page if user isn't authenticated in React/Django app
I’m using React for my frontend and Django for the backend, both are new to me and I've been spending a ton of time on this issue without solving it, so I'm really hoping someone might know the answer. When I visit my site at http://localhost:4000/ without being logged in, I see a black screen with the text "Loading…” (refer to protected_route code below), instead of being redirected to the login page. This happens when I navigate to any protected routes while not logged in. Currently my only routes that are not protected are the login and register pages, which if I manually go to those they work correctly. After I login, the JWT tokens are correctly stored to the httpOnly cookies, but I do see the “Loading…” page until I manually refresh the page, then I see my protected routes. I was thinking maybe the authentication check is firing too quickly and the state isn't ready yet and it gets stuck on the "Loading..." screen? But I'm unsure how to fix that if it's the case... I'll post the relevant code below, but I'll also share the github repo here. Here’s the browser/server consoles when going to a page … -
What is a better way to push updates to a .exe file on Client Machine? (Exe created by pyinstaller)
Context For a bit of a context I am a self taught developer who is currently working as a freelancer on Fiverr. I work using the Django and the React Framework. I develop different kinds of Automation Softwares for my clients, most of Initially, I used to deliver source code to my clients and they used to install Python and than the libraries to get the program working on their side and as you all can guess this method was very inefficient. So, I learned a trick to convert my django code into .exe format using Pyinstaller. So, now all the clients have to do is to doouble click the exe file which launches the web app in their browser. Problem But now I am facing another problem. As, I am now dealing with some repeating clients who are often contacting me to add features. But now the problem is that every time I update their web apps to add new features they all have to manually install the new version and than shift all the data manually to the newer version which is a big problem ofcourse. So, some of them are asking me to do something so that … -

Python Django Annotations over multiple relationships

What am I doing wrong here? Is it finally possible to achieve this? -

1 out of many calls to overridden django `Model.save()` generates a pylint `unexpected-keyword-arg` error - how do I satisfy it?
I implemented and have been using this model (super)class I created for years, and it is completely stable on an active site. I just made a small minor tweak to some completely unrelated portion of its code, and checked my work (on my machine) with the latest superlinter. Our CI tests on github currently use an old superlinter and it has never complained, so I was surprised to see a linting error on code I haven't touched in years. My model class has an overridden save() method, which adds a few extra arguments that it pops off kwargs before calling super().save(). I have a number of calls to save inside the class, and the linter is fine with thos extra arguments everywhere else, except in 1 spot (an override of from_db): @classmethod def from_db(cls, *args, **kwargs): # Instantiate the model object rec = super().from_db(*args, **kwargs) # If autoupdates are not enabled (i.e. we're not in "lazy" mode) if not cls.get_coordinator().are_lazy_updates_enabled(): return rec # Get the field names queryset_fields = set(args[1]) # field_names # Intersect the queryset fields with the maintained fields common_fields = set(cls.get_my_update_fields()).intersection(queryset_fields) # Look for maintained field values that are None lazy_update_fields = [fld for fld in common_fields … -

django-channels integration tests with pytest?
I am trying to create a simple live-server style test fixture for pytest for testing with django-channels. I came up with the simplest solution: import pytest @pytest.fixture(scope="function") def channels_live_server(request): from channels.testing import ChannelsLiveServerTestCase class MyChannelsLiveServerTestCase(ChannelsLiveServerTestCase): @property def url(self): return self.live_server_url server = MyChannelsLiveServerTestCase() server._pre_setup() yield server server._post_teardown() When used, the web server starts in the background and serves the web pages just fine... except it is using "production" settings, which means the database used is NOT the test database. Any ideas how to fix this? I do realize, that multiprocessing at some later stage is using Popen and starts the server using spawn context. I am on macOS, if that matters. -

how should index.html be served with django gunicorn and nginx?
my webapplication entirely dockerized and is written with a django and gunicorn backend and an nginx frontend. nginx is needed as a proxy and to serve static files. nginx has access to the static files via mounted volume from django. I would like the entire frontend not as django templates. i'm not understanding if index.html can be directly managed by nginx like this first configuration. (first nginx.conf) or if the request should regardless firstly reach django and then, ascertained that the wanted file is a static file (index.html), be redirected with the url changed in /static/... so that can be caught by nginx. (second nginx.conf). Thanks for everyone that will eventually help me.

Wrong path for my default image Django app
i'm making a music streaming website with Django and i want to display the playlists in the homepage. All is working exept for the palylists in which i didn't upload an image. I set a playlist default image but the browser doesn't find the default image because of the wrong path. How can i fix it? (Probably it's an easy thing but i'm new to Django...) html: {% for playlist in my_playlists %} <a href="{% url 'music:playlist' playlist.playlist_id %}"><img src="{{ playlist.image.url}}" alt="playlist image"></a> {% endfor %} models.py: class Playlist(models.Model): playlist_id = models.AutoField(primary_key=True) user = models.ForeignKey(User, on_delete=models.CASCADE) playlist_name = models.CharField(max_length=50, default="name") image = models.ImageField(upload_to="playlist_images/", validators=[FileExtensionValidator(allowed_extensions=['jpeg', 'jpg', 'png'])], default="images/music-placeholder.png") plays = models.IntegerField(default=0) songs = models.ManyToManyField(Song, related_name='playlist') slug = models.SlugField() views.py: def homepage(request): songs = Song.objects.all() user = request.user if user.is_authenticated: my_playlists = Playlist.objects.filter(user=user) return render(request, 'homepage.html', {'songs': songs, 'my_playlists': my_playlists}) setting.py: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') I got this error: Not Found: /media/media/images/music-placeholder.png but the path should be this /media/images/music-placeholder.png: -
How can I output a selection of Blog objects in a ListView in Django searched via ForeignKeys of two other different models?
I have three models like this: 1: class Blog(models.Model): title = models.CharField() published = models.DateField() ... 2: class AuthorList(models.Model): blog = models.ForeignKey(Blog) author = models.ForeignKey(User) lastTimeEdited = models.DateTimeField() ... 3: class CommentsList(models.Model): blog = models.ForeignKey(Blog) commentAuthor = models.ForeignKey(User) commentPosted = models.DateTimeField() ... My class based ListView looks like this: class DashboardView(LoginRequiredMixin, ListView): model = Blog template_name = 'app/dashboard.html' paginate_by = 5 def get_queryset(self) -> QuerySet[Blog]: user = self.request.user author = #HERE I want a queryset of all blogs, where the requested user is one of the authors. commentator = #HERE I want a queryset of all blogs, where the requested user is one of the commentators. blogs = author|commentator return blogs.order_by(#HERE I want to order them by the lastTimeEdited-Field or the commentPosted-Field) So I want to list all the blogs that the user has to do with in one way or another. I also want to order them by the lastTimeEdited value if the user is an author or by the commentPosted value if the user is a commenter. How can I do that? I've already looked for the solution in other posts, but couldn't find the right solution for my problem. -
Django timeslots not showing up in form
I am trying to build a Django booking system where I am trying to implement the logic that if a timeslot is booked for a certain day, that timeslot should not be clickable (disabled). And beside the timeslot it should read (booked). This is my implementation. But my logic is not working. No timeslots are showing up. Can anyone help me point out the problem here? Thanks! My models.py: class Timeslot(models.Model): start_time = models.TimeField() end_time = models.TimeField() slot_text = models.CharField(max_length=100) def __str__(self): return self.slot_text class Appointment(models.Model): name = models.CharField(max_length=100) phone = models.CharField(max_length=20) email = models.EmailField() date = models.DateField() timeslot = models.ForeignKey(Timeslot, on_delete=models.CASCADE) booked_on = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.name} - {self.date} - {self.timeslot.slot_text}" My views.py: def check_availability(date): timeslots = Timeslot.objects.all() booked_timeslots = Appointment.objects.filter(date=date).values_list('timeslot', flat=True) available_timeslots = [(timeslot, timeslot.id not in booked_timeslots) for timeslot in timeslots] return available_timeslots def book_appointment(request): available_timeslots = [] form_data = {} if request.method == 'POST': name = request.POST.get('name') phone = request.POST.get('phone') email = request.POST.get('email') date = request.POST.get('date') timeslot_id = request.POST.get('timeslot') form_data = { 'name': name, 'phone': phone, 'email': email, 'date': date, 'timeslot': timeslot_id, } if 'check_timeslots' in request.POST: if date: available_timeslots = check_availability(date) else: messages.error(request, 'Please select a date to check available timeslots.') elif 'book_appointment' in …
