Where does the smartselect URLS belong?
I'm trying to set op SmartSelect in my django project so I can chain dropdown menu's. I do not understand how/where the urls belongs for the installation? urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^chaining/', include('smart_selects.urls')), ) This is what their official installation guide says. Though this is either and old version of Django or i'm doing something wrong as I have not seen any URLS file written this way before and VScode does not recognize it. What am I doing wrong? -

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).

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? -
Modelos Django. Relaciones [closed]
La idea es que hayan dos modelos, Grupo y Jugador. Mi objetivo es que hayan distintos Grupos y que cada grupo tenga jugadores, cada jugador puede pertenecer a más de un grupo. Dentro de un grupo, el jugador tiene cierto puntaje, pero dentro de otro grupo, el jugador puede tener otro puntaje distinto. 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) Lo que me está costando es cómo aclarar que el jugador tiene una cantidad x de partidas ganadas en el grupo A y también tiene una cantidad "y" de partidas ganadas en el grupo B. -
Django - Loop and Return in JS or in Python?
In general, if making a Post call from JS to the backend, how to best handle a loop while keeping the UI interactive? For example, if I have a function to update multiple files, should I loop the Ajax calls in Javascript, and wait for each file edit function return at once to display on the web page? Wouldn't this risk losing data/interrupting the process if the web page is closed? On the flip side, sending all the data to the backend would remove that risk, but since only 1 Return can happen, the UI wouldn't be ideal/dynamic. Are database writes/reads the solution to this conundrum, or am I missing something? Cheers. -

Django lookup by JSONField array value
Let's say I have MySQL database records with this structure { "id": 44207, "actors": [ { "id": "9c88bd9c-f41b-59fa-bfb6-427b1755ea64", "name": "APT41", "scope": "confirmed" }, { "id": "6f82bd9c-f31b-59fa-bf26-427b1355ea64", "name": "APT67", "scope": "confirmed" } ], }, { "id": 44208, "actors": [ { "id": "427b1355ea64-bfb6-59fa-bfb6-427b1755ea64", "name": "APT21", "scope": "confirmed" }, { "id": "9c88bd9c-f31b-59fa-bf26-427b1355ea64", "name": "APT22", "scope": "confirmed" } ], }, ... Any way I can filter all of the objects who's actors name contains '67', for example? Closest variant I have is that I got it working like that: queryset.filter(actors__contains=[{"name":"APT67"}]) But this query matches by exact actor.name value, while I want to to accept 'contains' operator. I also have it working by quering with strict array index, like this: queryset.filter(actors__0__name__icontains='67') But it only matches if first element in array matches my request. And I need that object shall be returned in any of his actors matches my query, so I was expecting something like queryset.filter(actors__name__icontains='67') to work, but it's not working :( So far I have to use models.Q and multiple ORs to support my needs, like this - search_query = models.Q(actors__0__name__icontains='67') | models.Q(actors__1__name__icontains='67') | models.Q(actors__2__name__icontains='67') | models.Q(actors__3__name__icontains='67') queryset.filter(search_query) but this looks horrible and supports only 4 elements lookup(or I have to include more … -

But whenever I edit the data to update it, a new entry is created in database models.py class User(AbstractUser): pass def __str__(self): return self.username class Detail(models.Model): """ This is the one for model.py """ username = models.ForeignKey(User, on_delete=models.CASCADE, null=True, default="") matricno = models.CharField(max_length=9, default="") email = models.EmailField(default="") first_name = models.CharField(max_length=200, default="") last_name = models.CharField(max_length=255, default="") class Meta: verbose_name_plural = "Detail" def __str__(self): return self.first_name+ " "+self.last_name views.py @login_required(login_url="signin") def details(request): form = Details() if request.method == "POST": form = Details(request.POST) if form.is_valid(): detail = form.save(commit=False) detail.username = request.user detail.save() return redirect(success, pk=detail.pk) else: form = Details(initial={"matricno":request.user.username}) return render(request, "details.html", {"form":form}) def success(request,pk): return render(request, "success.html", {"pk":pk}) def updatedetails(request, pk): detail = Detail.objects.get(id=pk) form = Details(instance=detail) if request.method == "POST": form = Details(request.POST, instance=detail) if form.is_valid(): form.save() return redirect(success, pk=detail.pk) return render(request, "details.html", {"form":form}) urls.py from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path("details/", views.details, name="details"), path("success/<int:pk>/", views.success, name="success"), path("edit/<int:pk>/", views.updatedetails, name="updatedetails"), ] The template used for rendering out the form to input user details goes as follows <!DOCTYPE html> <html lang="en"> <head> … -
Get values of Enum fields from Django Queryset
I have a model with an enum column, e.g. from django_enum_choices.fields import EnumChoiceField class Service(Enum) MOBILE: "MOBILE" LAPTOP: "LAPTOP" class Device(models.Model): service = EnumChoiceField(Service) ... Is it possible to get get the query results with the enumerated column being the value of the enum? For example: If I do: query = Device.objects.values("service") print(query) I get: <QuerySet [{'service': <Service.MOBILE: 'MOBILE'>}, {'service': <Service.MOBILE: 'MOBILE'>}, {'service': <Service.LAPTOP: 'LAPTOP'>}]> I wish to get: <QuerySet [{'service': 'MOBILE'}, {'service': 'MOBILE'}, {'service': 'LAPTOP'}]> I get errors when I run: query = Device.objects.values("service__value") or query = Device.objects.values("service.value") I want to something like how we can get value of an enum field by saying mobile_service = Service.MOBILE # <Service.MOBILE: "MOBILE"> mobile_service_as_string = mobile_service.value # "MOBILE" The errors: django.core.exceptions.FieldError: Cannot resolve keyword 'value' into field. Join on 'service' not permitted. django.core.exceptions.FieldError: Cannot resolve keyword 'service.value' into field. Choices are: service, .. -
Django Selenium Parsing Data
How can return WebDriver=auth in function parameters? I have a task.py file in which, first, in the login function, I use Selenium to log in to my personal account, then the form_fill function receives the Url parameters in which the form is filled, and the WebDriver and returns the data and the driver. I'm trying in views.py to first call the login function for authorization and return the WebDriver to another form_fill function. task.py def login(url): driver = webdriver.Chrome(service=service,options=options) driver.maximize_window() driver.get(url) driver.find_element(By.ID,"login").send_keys(LOGIN) driver.find_element(By.ID,"password").send_keys(PASSWORD) driver.find_element(By.ID,'bind').click() return driver def form_fill(url_pars,driver,name_flat): driver.get(url_pars) driver.find_element(By.ID,"epd_field").click() codplat=driver.find_element(By.CLASS_NAME,"home_right").text driver.find_element(By.XPATH,'//span[contains(text(),"name_flat}")]'.format(name_flat)).click() driver.find_element(By.CLASS_NAME,"js-find-btn").click() driver.find_element(By.CLASS_NAME,"js-more-btn").click() driver.find_element(By.CLASS_NAME,"btn-close-pop").click() return [driver,codplat] views.py class AuthView(TemplateView): template_name="mos_sel/login.html" def get_context_data(self, **kwargs) : context=super().get_context_data(**kwargs) # login(URL_LOGIN) return WebDriver in auth auth=login(URL_LOGIN) return context views.py class PaymentListView(AuthView,ListView): template_name='mos_sel/parse_list.html' model=Flat context_object_name='fields' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['name_flat']=Flat.objects.get(pk=self.kwargs['pk']).name_flat # How get WebDriver in parameters call form_fill function forma_fill=form_fill(GET_USLUGA_URL,auth,context['name_flat'].upper()) return context login.html {% extends "base.html" %} {% block content %} <h3>Enter for authorization</h3> <a href="{% url 'AuthView' %}"><button type="button" class="btn btn-success">Enter</button></a> {% endblock content %} parse_list.html {% extends "base.html" %} {% block sidebar %} <h5>{{name_flat}}</h5> {% for field in fields %} {{field.cod_platelshika}} {{field.period_oplaty}} {{field.summa}} {% endfor %} {% endblock sidebar %} I want get WebDriver in function fill_form parameters -
Render multiple models with pk in a single view
I'm trying to pass lesson.price, and lesson.invoice_id from Lesson model and student.student_id from Student Model into the single view so that I can display them in a template. However, Lesson model has a field "student" which has a foreign key to User, not to Student model. You will see my code for view class is wrong since I have no clue how to get a proper student object with a primary which is used for lesson object. How could I get a proper student object with lesson_id primary key in view class? class User(AbstractUser): '''User model for authentication and lessons authoring.''' class Role(models.TextChoices): ADMIN="ADMIN",'Admin' STUDENT="STUDENT",'Student' TEACHER="TEACHER",'Teacher' id = models.AutoField(primary_key=True) username = models.CharField( max_length=30, unique=True, validators=[RegexValidator( regex=r'^@\w{3,}$', message='Username must consist of @ followed by at least three alphanumericals.' )] ) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) email = models.EmailField(unique=True, blank=False) gender = models.CharField(max_length=255) address = models.TextField(default='') baseRole = Role.ADMIN role = models.CharField(max_length=50, choices=Role.choices) created_at = models.DateTimeField(default=timezone.now, blank=True) updated_at = models.DateTimeField(default=timezone.now, blank=True) def save(self, *args, **kwargs): self.role = self.baseRole return super().save(*args, **kwargs) def __str__(self): return self.first_name+" "+self.last_name class Student(User): student_id = models.CharField(max_length=10, default=uuid.uuid4) baseRole = User.Role.STUDENT student = StudentManager() class Lesson(models.Model): lesson_id = models.AutoField(primary_key=True) lesson_name = models.CharField(max_length=255) student = models.ForeignKey(User,on_delete=models.DO_NOTHING,related_name='studying', unique=True) teacher … -
Is it possible to pass command line arguments to a decorator in Django?
I have a decorator that is supposed to use a parameter that's passed in from the commandline e.g @deco(name) def handle(self, *_args, **options): name = options["name"] def deco(name): // The name should come from commandline pass class Command(BaseCommand): def add_arguments(self, parser): parser.add_argument( "--name", type=str, required=True, ) @deco(//How can I pass the name here?) def handle(self, *_args, **options): name = options["name"] any suggestions on this?
