Django find all rows matching 2 columns criteria
Imagine the model Event like this name email A u1@example.org B u1@example.org B u1@example.org C u2@example.org B u3@example.org B u3@example.org A u4@example.org B u4@example.org I would like to find all emails that contains name A and B. In the example ["u1@example.org", "u4@example.org"] Today I'm doing emails = [ e["email"] for e in models.Event.objects.filter(name__in=["A", "B"]) .values("email") .annotate(count=Count("id")) .order_by() .filter(count__gt=1) ] It's not working because I'm also getting duplicates of emails containing only one name (like u3@example.org). -
How I get data from a Input to run a function in Django
i following a django tutorial and i have troubles getting the data from a input in my HTML. This is the code from the tutorial: views.py def buscar(request): if request.GET["prd"]: producto = request.GET["prd"] articulo = Escucha.objects.filter(user__icontains=producto) return render(request, "Producto/resultados_busqueda.html", {"articulo": articulo, "query": producto}) else: mensaje = "Nos has introducido nada" return HttpResponse(mensaje) HTML: <html lang="en"> <head> <title>Busqueda de producto</title> </head> <body> <form action="/buscar/" method="get"> <input type="text" name="prd"> <input type="submit" value="Buscar"> </form> </body> </html> And this is the code I try to run: views.py def suma(request): if request.get["first"]: first = request.GET["Primer"] second = request.GET["Segundo"] variable = first + second return render(request, "resultado.html", {"variable": variable}) else: mensaje = "lo siento" return HttpResponse(mensaje) HTML (pruebas.HTML) <html lang="en"> <head> <title>Document</title> </head> <body> <form action="/pruebas/" method="get"> <input type="text" name="first"> <input type="text" name="second"> <input type="submit" value="suma"> <p>Resultado: {{ variable }}</p> </form> </body> </html> And the problem I get is: AttributeError at /pruebas/ 'WSGIRequest' object has no attribute 'get' Y really don't know what's the problem, for me the two codes are similar. -

Django / Python: Sorting QuerySet by field on first instance of foreignkey relation
I have the following 2 models, a Lesson model, that can have multiple start / end dates - each with their own Date model. class Lesson(models.Model): name = models.Charfield() (...) class Date(models.Model): meeting = models.ForeignKey( Lesson, verbose_name="dates", on_delete=models.CASCADE, ) start_date = models.DateTimeField( blank=True, null=True, ) end_date = models.DateTimeField( blank=True, null=True, ) For our project we need to order the Lessons by the start_date of their earliest Date instance. So far example, if I have the following data: MEETING A: DATE_1a: 2022-11-01 --> 2022-11-02 DATE_2a: 2022-12-10 --> 2022-12-11 MEETING B: DATE_1b: 2022-11-03 --> 2022-11-04 DATE_2b: 2022-11-05 --> 2022-11-06 Then the queryset should return [<MEETING A>, <MEETING B>] based on the start_date values of the DATE_1a/b instances. (2022-11-01 is earlier than 2022-11-03, al other Dates are ignored) However, what I thought would be a relatively simply query has proven to be a rather evasive problem. My initial approach of the default order_by method used all Date instances attached to a Meeting (and worse, returned a separate Meeting result for each Date instance) qs.order_by(F("dates__start_date").asc(nulls_first=True)) However -I could not conceive of a query to do what we need to happen.

Django displaying a static image through a variable from models that is in a JSON object

How to include the JSON Schema definition of a JSONField inside the OpenAPI schema generated by drf-spectacular?
By default, when using drf-spectacular to generate the OpenAPI schema, the JSONField will be typed as object or array. However, I have a JSON Field which is validated against a JSON Schema and I'd like this JSON Schema to be included on the OpenAPI schema. I couldn't find this specific scenario described on the docs of drf-spectacular, but however, I tried modifying it using @extend_schema but with no success. The model looks like this: Car(models.Model): name = models.CharField() data = models.JSONField("Car Data", validators=[JSONSchemaValidator(limit_value=my_schema)]) On the generated OpenAPI schema, this is represented as: data: type: object additionalProperties: {} nullable: true title: Car Data I'm not including a sample on how it should look because I'm seeking answers where this is possible in some pre-defined way. -
base.html only showing the context data in the home page
I have a ListView for my homepage that displays extra data using the get_context_data method. It works, but only in the url of the HomeView, the homepage, not in other templates after I extend the base.html file. Everything else in base appears, the only thing that doesn't is the context data. HomeView class HomeView(ListView): model = Product context_object_name='products' template_name = 'main/home.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) news = News.objects.all() ... context.update({ 'news' : news, ... }) return context base.html {% load static %} <body> <div class="navbar"> <a id="title" href="{% url 'home' %}">home</a> </div> ... <div class="side-bar"> <div class="article"> <h3>News</h3> {% for new in news %} <p>{{ new.title }}</p> {% endfor %} <a href="{% url 'news' %}"><p>See more</p></a> </div> </div> {% block content %}{% endblock %} ... </body> home.html {% extends 'main/base.html' %} {% block content %} <div> {% for product in products %} <p>Some text..</p> {% endfor %} {% endblock content %} Does this mean that I have to add a get_context_data method to every single view I have? Isn't that too repetitive and hard to change? -
Django models relation
The idea is that there are two models: Group and Player. My objective is that there are different Groups and each group has players. Each player can belong to one or more groups. Inside a group, each player has some points accumulated, but the same player can have different points accumulated in another group. class Player(models.Model): username = models.CharField(max_length = 200) won_games = models.IntegerField(default=0) class Point(models.Model): player = models.ForeignKey(Player, on_delete=models.PROTECT, related_name='points') val = models.IntegerField() group = models.ForeignKey(Group, on_delete=models.PROTECT, related_name='points') class Group(models.Model): id = models.CharField(max_length = 200) players = models.ManyToManyField(Player,related_name="groups") points = models.ManyToManyField(Point) I am confused because I don't know how to make that a player has "x" points in group A (for example) and also has "y" points in group B. I want to be able to show the data of a group, for each group, show its members and their points. -

Setting an initial value of an extra field on a ModelForm from an UpdateView
I have a form which is a modelform with two extra fields. In my model, it includes a PointField which is made up of an easting and northing (the X & Y components of the Point). On my modelform, I do not display the PointField and instead display two DecimalFields for the easting and northing: class QuoteForm(forms.ModelForm): easting = forms.DecimalField() northing = forms.DecimalField() class Meta: model = Quote fields = ('desc', 'client', 'contact', 'amount', 'easting', 'northing', 'note') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['note'].required = True self.helper = FormHelper() self.helper.form_method = 'post' self.helper.add_input(Submit('submit', 'Save Quote') ) For my CreateView I include a form_valid that takes the easting and northing and turns them into a point and updates the PointField record. For my UpdateView, I want to go backwards from the PointField and populate the Easting and Northing DecimalFields on my form. I am stuck on how to "pass" this information to my form. I tried a get_form in my UpdateView like this, but it fails: class QuoteUpdateView(PermissionRequiredMixin, UpdateView): permission_required = 'jobs.update_quote' redirect_field_name = 'dashboard' model = Quote form_class = QuoteForm template_name = "jobs/quote_form.html" template_name_suffix = '_form' def get_form(self, form_class=None): form = super().get_form(form_class) quote = self.object pt = quote.ptgeom pt.transform(2953) form.fields['easting'] … -

Join two queryset in Django ORM
I'm writing a view that returns this: [ { "field_id" : 1, "stock" : [ { "size" : "M", "total" : 3 } ], "reserved" : [ { "size" : "M", "total" : 1 } ] }, { "field_id" : 2, "stock" : [ { "size" : "M", "total" : 2 }, { "size" : "PP", "total" : 2 } ], "reserved" : [ { "size" : "PP", "total" : 1 }, { "size" : "M", "total" : 2 } ] } ] For this result, I used values and annotation(django orm): reserved = Reserved.objects.all().values("size").annotate(total=Count("size")).order_by("total") stock = Stock.objects.filter(amount=0).values('size').annotate(total=Count('size')).order_by('total')) It's ok for me, but I would like put the reserved queryset inside stock. Like this: [ { "field_id" : 1, "stock" : [ { "size" : "M", "total" : 3, "reserved": 1 } ], }, { "field_id" : 2, "stock" : [ { "size" : "M", "total" : 2, "reserved": 1 }, { "size" : "PP", "total" : 2, "reserved": 0 } ], } ] It's possibile?

AAC/ADTS to WAV in Flutter/Django
My Team and I are building a speech-to-text application for a specific purpose. The frontend is in Flutter and the backend is in Django I am using the flutter_sound package for Flutter and the only Codec it supports for recording audio is Codec.aacADTS and I am able to save the file using .aac or .adts On the backend (Django), we're using the Speech Recognition Library and when using the .aac or .adts file with this, it gives an error: ValueError("Audio file could not be read as PCM WAV, AIFF/AIFF-C, or Native FLAC; check if file is corrupted or in another format") We tried using another .wav file and speech recognition works. So, do I need to convert the .aac/.adts file to a .wav file? How should I do it, and should it be on the frontend or the backend? Any library/code snippets to help me with that?

django - different save methods for user actions and admin action
I have some items connected to users. When every item is added, timestamp is created through inheritance of BaseModel on auto_now field. By mistake when i added new field and populated i updated timestamps. I resolved timestamps with some custom migrations and copy data methods in django. What i wonder - is there possibility to override save method on admin to do only update_fields (so in other words with that i would not update update_at timestamp), while on user actions i want to retain original django save method which would update timestamp. So basically is it possible to have two different save methods? I know that i can override save method - but i don't know if i can have two save methods at the same time. -

comparing two (same) functions with same id <function ... at 0x7f490f225900> returns False in Django Middleware
I've created a middleware that modifies one argument for a view in process_view method. As this should do that to one particular view only, I'm comparing callback argument with the view function like this: from third_party_app import view_func class ModifyCodeKwargForViewFuncMiddleware(MiddlewareMixin): def process_view(self, request, callback, callback_args, callback_kwargs): if callback is view_func: raw_code = callback_kwargs["code"] normalized_code = utils.normalize_code(raw_code) return view_func(request, normalized_code) return None This works correctly on my development server; callback is view_func is True But it doesn't work on the server on heroku. I've logged callback and view_func right before comparing it and I noticed that their identifiers are the same (also on the heroku server), which is even weirder: class ModifyCodeKwargForViewFuncMiddleware(MiddlewareMixin): def process_view(self, request, callback, callback_args, callback_kwargs): logging.warning(f"callback is `{callback}`") logging.warning(f"imported view_func is `{view_func}`") logging.warning(f"callback is view_func {callback is view_func}") if callback is view_func: raw_code = callback_kwargs["code"] normalized_code = utils.normalize_code(raw_code) return view_func(request, normalized_code) return None The log entries look like this: callback is `<function view_func at 0x7f490f225900>` imported view_func is `<function view_func at 0x7f490f225900>` callback is view_func False How is this possible and how can I make it work? -

Django project on AWS not updating code after git pull
stackoverflowers. I am a Django newbie and I am having an issue. It's my first time ever deploying a Django project on AWS. I am running Postgres, Redis, Nginx as well as my project on Docker there. So everything is working fine, but when I change something on my local machine, push changes to git and then pull them on the AWS instance, the code is not refreshing at all. Only the static files are updating automatically (I guess because of Nginx). Here is my docker-compose config: version: '3.9' services: redis: image: redis command: redis-server ports: - "6379:6379" postgres: image: postgres environment: - POSTGRES_USER= - POSTGRES_PASSWORD= - POSTGRES_DB= ports: - "5432:5432" web: image: image_name build: . restart: always command: gunicorn project.wsgi:application --bind 0.0.0.0:8000 env_file: - envs/.env.prod ports: - "8000:8000" volumes: - ./staticfiles/:/tmp/project/staticfiles depends_on: - postgres - redis nginx: image: nginx ports: - "80:80" - "443:443" volumes: - ./staticfiles:/home/app/web/staticfiles - ./nginx/conf.d:/etc/nginx/conf.d - ./nginx/logs:/var/log/nginx - ./certbot/www:/var/www/certbot/:ro - ./certbot/conf/:/etc/nginx/ssl/:ro depends_on: - web Can you please tell me what to do? Please keep in mind I really am a newbie so if you would be kind to explain it I would be forever grateful! Thanks in advance! I tried deleting everything from docker and … -
Django model gives "TypeError: Object of type UUID is not JSON serializable" error on object create [closed]
I have created a django model as below : class ProjectHistory(models.Model): uuid = models.UUIDField(default=uuid4, editable=False) history = JSONField(default=dict, blank=True, null=True) version = models.PositiveIntegerField(default=0) sequence = models.PositiveIntegerField(default=0) project = models.ForeignKey(Project, related_name='projecthistory', on_delete=models.CASCADE) def Meta(self): unique_together = ("sequence", "project") def save(self, *args, **kwargs): sequence_list = ProjectHistory.objects.filter(project=self.project) self.sequence = sequence_list.count() + 1 super(ProjectHistory, self).save(*args, **kwargs) When I create the object for ProjectHistory model as below : sequence_list = ProjectHistory.objects.filter(project=project) projecthistory = ProjectHistory.objects.create(project=project, history=old_manifest) I see the following error : [29/Nov/2022 18:40:34] INFO [views.py:30] ProjectManifest GET begin [29/Nov/2022 18:40:34] INFO [views.py:203] Subtitle GET success 8 [29/Nov/2022 18:40:34] INFO [views.py:88] ProjectManifest GET end [29/Nov/2022 18:40:34] "GET /project/6e4f263f-3ed3-472c-8311-9202d29a4c4f/ HTTP/1.1" 200 8281 [29/Nov/2022 18:40:39] INFO [views.py:97] ProjectManifest POST begin: 6e4f263f-3ed3-472c-8311-9202d29a4c4f USER DATA : None [29/Nov/2022 18:40:39] INFO [views.py:133] ProjectManifest POST get project [29/Nov/2022 18:40:39] INFO [views.py:143] Project POST has a workspace : 119d535e-1bb0-4e95-b946-4d3ac4d16e0f but no workspacemember [29/Nov/2022 18:40:39] INFO [views.py:147] False - Workspace object (2) - None - None The history : {'fps': 24, 'text': {}, 'asset': {}, 'title': 'Your Video - 6e4f263f3ed3472c83119202d29a4c4f', 'width': 1080, 'height': 1920, 'images': {}, 'videos': {}, 'effects': {}, 'filters': {'preset': ''}, 'version': 1.0, 'bg_color': '00000000', 'duration': 0, 'elements': {}, 'subtitles': {}, 'user_uuid': None, 'audio_only': False, 'created_at': '2022-11-29 16:24:06', 'updated_at': '2022-11-29 16:24:06', 'subtitle_url': … -
Celery 4.4 + Redis - long ETA tasks, default_timeout
We are using Celery (celery==4.4.7) along with Redis broker We have some long ETA tasks with some tasks having ETA of now + 7 days. We were getting issues of the celery tasks being executed multiple times and during debugging we found that the reason is because default_timeout is 1 hour I looked here: celery tasks with long eta (8+ hours) are executed multiple times in a row when eta is reached and https://docs.celeryq.dev/en/4.4.0/getting-started/brokers/redis.html#visibility-timeout We want to increase the default_timeout to 7 days or a bit longer to 8 days. app.conf.broker_transport_options = {"visibility_timeout": 864000} Are there any negative consequences of doing this?
