<slug> path converter not working, but literal <slug> in URL works
When I try to visit this URL: http://127.0.0.1:8000/slugtest/ I get 404 page.

Nginx Gunicorn powered server unable to access media in a separate postgresql server
Long story short, my BE dev left midway through setting up my apps' BE server and I'm trying to pick up the pieces to find out what is left to do. I'm by no means any form of a developer, so I apologize in advance for asking silly questions and if I am lacking any details needed to better understand my problem.

Question about sorting by date inside a database using Django
I have a database, in which it's possible to find products by their name. The DB has ID, category, name, amount and date defined, and I was trying to create a separate search field that would let me search those items by the date they were added. The models.py looks like this: class Expense(models.Model): class Meta: ordering = ('-date', '-pk') category = models.ForeignKey(Category, models.PROTECT, null=True, blank=True) name = models.CharField(max_length=50) amount = models.DecimalField(max_digits=8, decimal_places=2) date = models.DateField(default=datetime.date.today, db_index=True) def __str__(self): return f'{self.date} {self.name} {self.amount}' And views.py looks like this: class ExpenseListView(ListView): model = Expense paginate_by = 5 def get_context_data(self, *, object_list=None, **kwargs): queryset = object_list if object_list is not None else self.object_list form = ExpenseSearchForm(self.request.GET) if form.is_valid(): name = form.cleaned_data.get('name', '').strip() if name: queryset = queryset.filter(name__icontains=name) return super().get_context_data( form=form, object_list=queryset, summary_per_category=summary_per_category(queryset), **kwargs) I've added the "date" field under the "name", following it's structure, but I kept getting the 'datetime.date' object has no attribute 'strip' error. Is there a different format for defining the date? When I've also added it to the search field in forms.py, it was seen there as a string. I've also found a similar post from How to make date range filter in Django?, but it didn't explained … -
In Django, restrict user view using class based views
I have this url pattern: path("user/<int:pk>", MyAccountView.as_view(), name='my_account'), And this view: class MyAccountView(DetailView): model = CustomUser When the user is logged Django redirect to that URL. The problem is that any user can access other users. For example, if the logged user has pk 25, he can access the view of user with pk 26 by writing in the browser url box: localhost:8000/user/26 I want that each user can access to his user page only, so if user with pk 25 try to access the url with pk 26, the access should be denied. Can you point me in some direction of how this is done? The Django documentation is very confusing in this respect. Thanks. -
How to combine two methods for uploading file?
I have a Django application And I have a upload functionality. And I have two methods that shows the extracted text: def filter_verdi_total_number_fruit(self, file_name): self.extractingText.extract_text_from_image(file_name) regex = r"(\d*(?:\.\d+)*)\s*\W+(?:" + '|'.join(re.escape(word) for word in self.extractingText.list_fruit) + ')' return re.findall(regex, self.extractingText.text_factuur_verdi[0]) def filter_verdi_fruit_name(self, file_name): self.extractingText.extract_text_from_image(file_name) regex = r"(?:\d*(?:\.\d+)*)\s*\W+(" + '|'.join(re.escape(word) for word in self.extractingText.list_fruit) + ')' return re.findall(regex, self.extractingText.text_factuur_verdi[0]) But as you can see. There are some duplicate code. Like: file_name and: re.findall(regex, self.extractingText.text_factuur_verdi[0]) So I try to combine this two methods in one method: def combine_methods(self, file_name): self.filter_verdi_total_number_fruit(file_name) self.filter_verdi_fruit_name(file_name) and then I try to call the combined method in the views.py: if uploadfile.image.path.endswith('.pdf'): content ='\n'.join(filter_text.combine_methods(uploadfile.image.path)) But then I get this error: can only join an iterable Exception Location: C:\Users\engel\Documents\NVWA\software\blockchainfruit\main\views.py, line 50, in post Raised during: main.views.ReadingFile Question: how can I change this? -
Unable to do exception handling in Django forms
I have made a ModelForm in which the user is supposed to enter date and time. I want to make sure that the time is in the correct format so I wrote convert_to_time function so that it can raise a ValidationError when the format of time is wrong but it is not working. I seem that the Exception part is not working. I mean the control is never going inside the Exception part. Here is the ModelForm import datetime class BookingForm(forms.ModelForm): class Meta: model = Booking fields = ['check_in_date', 'check_in_time', 'check_out_time', 'person', 'no_of_rooms'] def clean(self): cleaned_data = super().clean() normal_check_in = cleaned_data.get("check_in_time") str_check_in = str(normal_check_in) format = '%H:%M:%S' try: print("vukwqa") #This gets printed in the terminal. datetime.datetime.strptime(str_check_in, format).time() except Exception: print("srhni") #This does not get printed in the terminal. raise ValidationError( _('%(value)s Wrong time format entered.'), code='Wrong time format entered.', params={'value': str_check_in}, ) Is it not possible to do exception handling in forms.py because if it were a normal python program the control does go inside the exception part. Is there a different way to do it? Can someone please help? -

Event loop is closed while runing Celery tasks

Create editable spreadsheet-like table in Django site
I am making a planning site that uses a spreadsheet-like table where every day is a row and every school subject is a column. The table rows are all the days of a year and the columns are all the school subjects. The table cells have to be editable and stylable, so you can add and remove and highlight homework. Basicallly just like google spreadsheets. You have to be able to instantly edit the cell upon clicking on it. These edits have to be saved to a database, so that other users can follow along with the edits. But how can I save everything onedit to the database? How can I create this spreadsheet functionality in a Django website? I already tried html tables with contenteditable. Or should I use input forms? Could anyone provide with an example for this? -
Problems with Django Templatetag `regroup`
When using the regroup templatetag I encountered a problem where a Queryset would produce an empty list ([]) as a result. A similar Queryset (e.g. a Set with the same columns and filters however one filtervalue differed) worked perfectly fine. My Query looks like this: GraZeichen.objects.filter(gtid__id=gtid).values("id", "findno").exclude(findno=None, formid=0).annotate(values_id=GroupConcat( "formid", separator=',')).annotate(values_en=GroupConcat("fombez_en", separator=',')) and my Template looks like this: {% regroup zeichen|dictsort:'values_de' by values_en as zeichen_by_val %} {% for valgroup in zeichen_by_val %} {{ valgroup.grouper }} ({{ valgroup.list|length }}) <div> {% for zeichen in valgroup.list %} <div> <a href="alink"> <img ...> </a> </div> {% endfor %} </div> {% endfor %} As I said it works perfectly fine for some gtids, but if I compare the printed Queryset of gtids where it worked with the ones where it did not I can see no difference. What are the cases, where regroup would return an empty list? -

How to show output from different methods?

So that I can show the filtering strings in a texfield.

Filter by property in Django Rest
I have a model with a class property, to calculate a field based on some foreign key of the model. class Company(models.Model): field_id = models.AutoField(db_column='_id', primary_key = True) ... @property def status(self): opportunities = list(self.opportunities.all()) #logic ... # return status I want to filter on that new field. I have read different points of view, and some of them says that is not possible directly in django ORM. I've found one solution but i don't know if exits one more efficient. My solution would be override the queryset in the viewset if the param is in the request. Filter by a list comprehension and getting de queryset again. My problem is that I need to get all objects, calculate the status field and iterate. def get_queryset(self): if 'status' in self.request.GET: status = self.request.GET['status'] queryset = models.Company.objects.all() objects=[obj.field_id for obj in queryset if obj.status == status] queryset = models.Company.objects.filter(field_id__in=objects) else: queryset = models.Company.objects.all() return queryset -

Django/React: Fetching API endpoint works fine from within the application, but returns 404 when request comes from outside
So I made an React + Django app and decided to seperate it, so the backend would work just as a rest API, and frontend would send requests to it. The goal was to facilitate hosting it. As a single app it works fine. API requests are returned like so [25/Oct/2022 14:31:21] ←[m"GET /spotify/current-song HTTP/1.1" 200 236←[0m But then I seperated the frontend, installed cors headers in django to accept traffic from the react app and most of it works fine. However: the api call to fetch info from spotify API gets a response [25/Oct/2022 14:31:41] ←[33m"GET /spotify/current-song HTTP/1.1" 404 2←[0m Not Found: /spotify/current-song, even though this is the very same endpoint that worked when the call came from within the app. The API call from react app: const getCurrentSong = async () => { const song = await fetch(`${BASEURL}spotify/current-song`); if (!song.ok || song.status == 204) { return defaultSong; } const songJson = await song.json(); setSong(songJson); document.body.style.backgroundImage = `url('${songJson.image_url}')`; }; useEffect(() => { const interval = setInterval(() => { getCurrentSong(); }, 1000); setAppBackground(); getRoomDetails(); return () => clearInterval(interval); }, []); Django project urls.py: urlpatterns = [ # other, irrelevant path('spotify/', include('spotify.urls')), ] And django spotify app urls.py: urlpatterns = [ … -

Problem with starting a Django project in current directory?
I am trying to start a django project in my current directory. Online I found this command as a solution: django-admin startproject . ^(Also the command used by my lecturer in one of his videos) However when I enter this into my terminal I get: CommandError: '.' is not a valid project name. Please make sure the name is a valid identifier. Edit: The command works fine if I give it a valid project name and creates a new directory with the project. The '.' from my understanding is meant to signify that the project should be started in the current directory, so I don't understand why it is treating it as a name -
