How to set up a callable for Django Imagefield's >> default << parameter
So I have a Model that contains a couple hundred instances and I now added an imagefield logo. As I don't want to upload each and every logo via the admin manually, I want to set up a callable that returns the correct file path so I can just push all logos to media/company_logos. # models.py def logo_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return f'company_logos/{instance.symbol}' class Company(models.Model): symbol = models.CharField(max_length=50) logo = models.ImageField(upload_to='company_logos/', default=logo_directory_path(instance=symbol, filename=f'{symbol}.png')) This returns an error at instance=symbol saying Type 'str' doesn't have expected attribute 'symbol' Another approach was logo = models.ImageField(upload_to='company_logos/', default=f'company_logos/{symbol}') which returns a URL as src="/media/company_logos/<django.db.models.fields.CharField>" I am not quiet sure how to set this up as I cant fully understand the official docs. My desired outcome is to have a URL for default like so: company_logos/IBM.png with field symbol being the corresponding part (I tried it via f-string). -

import module in Django
I have a project with structure like on this picture. Folders structure Where 'backend' folder is Django project folder. I need to import module from another folder 'main' inside Django app file, i.e. import main.Text_Generator in backend.app.views file. I tried: from ...main.Text_Generator import *. This raise an error: "attempted relative import beyond top-level package" And from main.Text_Generator import *, also error "No module named 'main'" What is the correct way to do such import? -
How save edit form in multilanguage project
I'm studying Django from the book Django 2 by Examples. I'm trying to improve a project which starts in chapter 10. Now, I'm trying to add multilingualism with the help of "django-parler". In general I did it, but it seems to me that there are better ways. Views are implemented as classes that are inherited from mixins. If a language other than the default language is selected on the page, the form still comes with the value of laguage_code field equal to default. I tried unsuccessfully to change this field in the form_valid method. The form was still saved with the default language. The only option that works for me is this, by it looks like kludge: def form_valid(self, form): language = translation.get_language() _course = form.save(commit=False) try: course = Course.objects.get(pk=_course.id) except Course.DoesNotExist: course = Course() course.owner = self.request.user course.set_current_language(language) cd = form.cleaned_data course.subject = cd['subject'] course.title = cd['title'] course.slug = cd['slug'] course.overview = cd['overview'] course.save() return redirect(reverse('courses:manage_list')) Maybe someone knows a more elegant way to implement this? I will be grateful. -
POST from Python file to Database in Django
I am developing an application in Django which uses machine learning. For now, I have trained the model and have created a list in views.py .

Django View Not Being Called from Template Form
This is my first time using Django (and I'm a beginner in web development in general), so I'm making a very simple project. It's a "daily check-in" app, where every day I click a button to check in, and I can view the history to see days I checked in or missed. The page is very minimal right now: My problem is I can't get the buttons to connect to their functions. Following along the official documentation, my current understanding is that the Django way to handle input is to wrap elements in a <form> that POSTs to a view, which is mapped in urls.py. Snippet of home.html: <div id="buttons-container"> <form action="{% url 'checkin-checkin' %}" method="post" style="display: inline;"> {% csrf_token %} <input type="button" value="Check in"> </form> <form action="{% url 'checkin-history' %}" method="post" style="display: inline;"> {% csrf_token %} <input type="button" value="View history"> </form> </div> Snippet of views.py: def home(request: HttpRequest) -> HttpResponse: # query DB to see if user is checked in... checked_in = True # hard-coded for now return render(request, "checkin/home.html", context={ "title": "Daily Check-in", "checked_in": checked_in, }) def checkin(request: HttpRequest) -> HttpResponse: print("called checkin") return home(request) # temp, just to return something def history(request: HttpRequest) -> HttpResponse: print("called history") … -

Handle HEAD request method using gunicorn and django
Is there a way to force gunicorn to pass the handling of "HEAD" request method to a drf application? Currently, I have a view which looks similar to the code below :- @api_view(["POST", "GET", "DELETE", "PUT", "PATCH", "HEAD"]) @renderer_classes([ProxyRender]) def my_proxy_view(request, path=""): return proxy_dispatch( urljoin(settings.PROXY["ENDPOINT"], path), request, ) However, when sending a "HEAD" request to the endpoint it seems like gunicorn or Django is the one handling the response, not my view as invoking my view should yield a head result of the service behind. $ curl -I "http://localhost:8000/proxy/some-endpoint" HTTP/1.1 200 OK Server: gunicorn Date: Sat, 20 Aug 2022 15:29:57 GMT Connection: close Content-Type: application/json Allow: HEAD, POST, PUT, DELETE, GET, PATCH, OPTIONS X-Frame-Options: DENY Content-Length: 106 Vary: Cookie X-Content-Type-Options: nosniff Referrer-Policy: same-origin -
Get gzip file from endpoint, extract data and add to database improvements
I currently have a script that fires a request to an API endpoint which returns a csv.gzip file - which roughly contains 75,000 rows and 15 columns. I download this files to the webserver disk storage, unzip the file to .csv and then loop through every row and add the data into my database. Finally deleting the files saved to disk. The process currently takes between 5 and 10 minutes to complete. I'm sure there is areas of improvement but not sure how to implement them. Some of them is: Save csv data to variable rather than on disk. Bulk import the data into my database. I'm sure there are other improvements to be made, so any advice would be appreciated. response = oauth.get(realm) content = ET.fromstring(response.content) coded_string = (content.find('.//pricefile')) decoded_string = base64.b64decode(coded_string.text) with open('test.csv.gzip', 'wb') as f: f.write(decoded_string) with gzip.open('test.csv.gzip', 'rb') as f_in: with open('test.csv', 'wb') as f_out: shutil.copyfileobj(f_in, f_out) with open('test.csv') as f: reader = csv.reader(f) next(reader) for row in reader: pricing.objects.update_or_create( product_id=row[0], date=datetime.now(), defaults={ 'average_price': Decimal(row[1] or 0), 'low_price': Decimal(row[2] or 0), 'high_price': Decimal(row[3] or 0), ... }) os.remove('test.csv') os.remove('test.csv.gzip') -

Django & Celery: How to start a thread in AppConfig() only once?

How can I make the thread start only once even with Celery? -
CSRF_token is not valid in djnango Ajax multiple request from same page
I'm trying to perform a OTP-based login in my project. So I have a form with email and password field in the login form and when I submit it through AJAX request I check for the email and password in the database, if the values are correct then I will send an OTP through email and display a new OTP field on the same page for Entering the OTP for verifications. Till now everything is working fine but after entering the OTP when I try to re-submit the form, I got an error csrf_token is not valid.

Models.py: class productsdefinition(models.Model): Products = models.CharField(max_length=Lenght200, default='NA') Status = models.CharField(max_length=Lenght10, choices=Utilities_CSP.PRODENG_CHOICES) Tester = models.ForeignKey(tester, on_delete=models.CASCADE, null=True) Board = models.ForeignKey(board, on_delete=models.CASCADE, null=True) TestProgram = models.CharField(max_length=Lenght200, default='') ProgramLoad = models.ForeignKey(ProgramLoad, on_delete=models.CASCADE, null=True) ListProgramEG = Utilities_CSP.ExtractProgEG() Probecard = models.CharField(verbose_name='Probe Card',max_length=Lenght200, choices=ListProgramEG, null=True) ProgramEG = models.CharField(verbose_name='Program EG',max_length=Lenght200, choices=ListProgramEG, null=True) forms.py: class ProducDefForm(forms.ModelForm): global tempfield i = 0 tempfield = [] for var in list(vars(productsdefinition()).keys()): if i <= 1: pass elif var == "Date_added": pass elif var == "LastModified": pass elif var.find("_id") != -1: var = var.replace("_id","") tempfield.append(str(var)) else: tempfield.append(str(var)) i = i + 1 class Meta: model = productsdefinition fields = tempfield def __init__ (self, *args, **kwargs): super(ProducDefForm, self).__init__(*args, **kwargs) ListProbecard = Utilities_CSP.ExtractProgEG() self.fields['Probecard'].choices = ListProbecard So my field ProgramEG work fine, when i try to put the list (of choice) to ensure that the field Probecard work, it don't work, it tell me "Select Choice in not valid,...." Do you have any idea where can be the erorr ? In the Table of the DB ? -
Django Excell structure
I need to make an webapp that is based on excell. There should be two kind of groups one for the user which can edit and view data and one for staff which can also create data to work for the user. Each of them have restricted view, user should only see their data while staff should see everything what every user had done or other staff member changed. I cant wrap my head around about those restrictions. my login is like that class Einloggen(LoginView): template_name = 'SCHUK/Einloggen.html' fields ='__all__' redirect_authenticated_user = True def get_success_url(self): if self.request.user.groups.filter(name='Personalverwaltung').exists(): return reverse('Dashboard') else: return reverse('Schulverzeichnis', args=[self.request.user.pk]) but when it comes to display data for the staff, there I hit a wall. class Dashboard (LoginRequiredMixin, ListView): model = SchulverzeichnisTabelle template_name = 'SCHUK/Dashboard.html' context_object_name = 'Dashboard' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['Schulverzeichnis'] = SchulverzeichnisTabelle.objects.all() return context while I can list everything with Foreignkeys the data that staff creates is not listed bc a foreignkey only show one entry when I use a mtm field I get this in my template <QuerySet []> reading docs and all you cant read individual entries from a mtm only what mtm has stored How can I show each … -
