Django reload data from model.py
Im working on a Django project and I want to dynamically load images to the page. the images are create each 10 mins. The problem is that when I do f5 or crl f5 to reload the page and check the new image is not there, then I check the list of images and also is not updated, only when I crtl+s the models.py file the page get the new image (no changes are made). This is how i get the list of images in the folder: models.py file: class ItemsFolder(): files_folder=os.listdir('C:/Users/Documents/TestImages/') class Folder(Page): ##other variables## files_folder=ItemsFolder().files_folder and my template.hmtl {% for card in page.files_folder %} <div class="col-md-4 d-flex align-items-stretch"> <div class="card mb-3 text-center"> <a href="{{ card.url }}"> <picture> <img src="{% static card %}" alt="{% static card %}"class="lazy card-img-top"> </picture> </a> </div> </div> {% endfor %} -

Images being left untracked
I've added plenty of pictures up to now but I never had an issue loading them until now. It seems no matter what picture I add to my project it just gets left as untracked/doesn't load... I tried the command echo -e "a\n*\nq\n"|git add -i as I seen in a post and the picture went from untracked to "Added" but it still didn't seem to fix my problem . I'm loading the image through background-image: url({% static 'dentist/img/bg-img/tooth.jpg' %}); I cleared my browser data restarted my editor and everything . The image is in the static folder under dentist/img/bg-img so i'm pretty sure my code is correct -
Django Url map with parameter
I am trying to create a web app, that allows you to access one item by a url like items/<str:id> and edit that item via items/<str:id>/edit. Everything worked fine since I tryed to create a form action with that url: <form action="{% url 'items' item_id 'edit' %}" method="POST"> (this form is contained into edit.html, which is the template rendered by my edit function) Of course the solution I came up with did not work at all, but I am wondering if there is a correct way to achieve this kind of form action. How would you do this? my edit function (views.py): def edit(request,id): item = get_item(id) if item is not None: if request.method == "POST": print(request.POST["content"]) return render(request, "webapp/edit.html", { "item_id": id }) Error returned: NoReverseMatch at /webapp/it1/edit/ Reverse for 'webapp' with arguments '('it1', 'edit')' not found. 1 pattern(s) tried: ['webapp\\/(?P<id>[^/]+)$'] I hope I'm making myself clear, I'm new to django. -
Data is being changed to FLOAT or leading zeros being DROPPED from the uploaded file
I am trying to upload file using a Django front end page on the server. When I see the uploaded file on the server or display it on Django front end page, I see that zip codes are either becoming float or leading zeros from the zip codes are being removed. Case 1. Conversion to FLOAT. Input Data:- Jhon,, Jeff, 0011, Berry, 012, Output Data:- Jhon Jeff 11.0 Berry 12.0 Case 2. Leading zeros being removed. (Note in case 2, there are no null zip code rows.) Input Data:- Jeff, 0011, Berry, 012, Output Data:- Jeff 11 Berry 12 Since in the US, zip codes should contain leading zeros and a three digit zip code is invalid. It is crucial for me to keep the zeros. Is there any solution to this problem? On html page. I am simply using following options. <form method="post" enctype="multipart/form-data" action="{% url "my_upload_url" %}"> <input type="file" id="browse" name="myfile"> <button id="upload" type="submit">Upload</button> </form> On back-end I am receiving the uploaded file using below. myfile = request.FILES.get('myfile', None) Any help will be great since I am not able to find workaround to this issue. Thanks. -

Django reverse lookup to get latest
I have a model structure as below, ACTIVE_STATUS = ['waiting', 'loading', 'starting', 'running', 'stopping'] INACTIVE_STATUS = ['stopped', 'finished', 'failed', 'lost'] ALL_STATUS = ACTIVE_STATUS + INACTIVE_STATUS class Task(models.Model): name = models.CharField(max_length=20) class Job(models.Model): task = models.ForeignKey(Task, related_name='jobs') timestamp = models.DateTimeField(auto_now_add=True) status = models.CharField(choices=zip(ALL_STATUS, ALL_STATUS), max_length=20) How can I annotate the "latest timestamp and its status" into Task queryset?

Django : enable CORS
I'm hosting an API on heroku. I try to use my API whith react native. I heard about CORS that I have to enable before using my API. I tried to do that.

Pytest and Django, proper method for creating module scoped fixtures
pytest module scoped fixtures that use the django test database are perplexing us. We want a fixture, that creates an entry in the database, once per test module. This works, but it's very clunky: import pytest @pytest.fixture(scope='module') def site(django_db_setup, django_db_blocker): with django_db_blocker.unblock(): address = models.Address.create(..) site = models.Site.create(address=address, ..) yield site with django_db_blocker.unblock(): site.delete() address.delete() We've noticed that django_db_setup is required, because if this fixture is the first one called, the test database won't be set up and the fixture will be created in the non-test database! For complicated objects that have more than one or two related models, the fixture becomes very ugly. Is there a better way to do this? -

Django annotate queryset with counting its members by condition
I have a model: class Event(models.Model): start_date = DateTimeField() end_date = DateTimeField() I want to count all events which are of the same day and include this count as annotation field daily_events to the each member of queryset. I want to solve this on database side for speed. My code so far: from django.db.models import F, Q, DateTimeField, Count from django.db.models.functions import TruncDate events = Event.objects.all() events = events.annotate( daily_events=Count('pk', filter=Q(start_date__date=TruncDate(F('start_date'))))) for event in events: print(event.daily_events) For example I have 4 events, and first 3 at the same day, so desired output should be: 3 3 3 1 but current output is wrong: 1 1 1 1 Any advices? -

dynamic, scheduled push notifications using Celery (Django)

Django, how to set a filter based on a queryset?
I have a queryset given by three different models: class Sottocategoria(models.Model): name = models.CharField('Nome del sottoprodotto', max_length=30) class A(models.Model): codice_commessa=models.ForeignKey() prodotto=models.ForeignKey() sottocategoria=models.ForeignKey(Sottocategoria) class B(models.Model): quantity=models.ForeignKey() price=models.DecimalField() sottocategoria=models.ForeignKey(Sottocategoria) Now I have set the following for loop: for sottocategoria_id, totale in (B.objects.values_list('sottocategoria__id').annotate(totale=(Sum(F('quantity') * F('price')))): .... I have the need to filter sottocategoria__id in the models B, that are present in the model A. Ad example If I have in the model A sottocategoria equal to {'abc','abcd','abcdf'} and model B sottocategoria equal to {'abc','abcd','abcdf', '1234'}, in my for loop I want to filter only {'abc','abcd','abcdf'}.
