How can I mix __str__ and @property?
I have question: I have some property decorator on model in Django: @property def replace_name(self): if not self.name: if self.pay: return self.registration_number else: return self.number else: return self.name When I get my data on page - If I do not use NAME.It means that when I enter data I leave field Name empty it returns me ID of model!But I want that it will return me registration_number! How I understand on this involves this method: def __str__(self): return f'{self.name}' Now it looks like this!But I have idea to added here: def __str__(self): return f'{self.name}{self.registration_number}{self.number}' After I added this it returns me what I want!This data!But!The problem is that @property does not working!It is returns me all data !How to mix this 2 methods to have normal working code?Can anybody explain!I know this way in str add is not correct!Please help! -

Django: right-align output in admin listview
How can I output a DecimalField right-aligned in Django admin listview? It makes much more sense to have column of, say, prices, right-aligned. I tried this: django align right cannot align, but it doesn't work, presumably, because it doesn't change the output behaviour. -
how to check if I got the right function
I have a model that has 2 foreign keys, therefore I also have a function in view which has to get one of 2 different functions. That's what I want to verify and I wonder how it is possible? models.py class HotelFacilities(models.Model): name5 = models.ForeignKey(HotelSingleRoom, related_name='name', on_delete=models.CASCADE, blank=True, null=True) name_5 = models.ForeignKey(HotelDoubleRoom, related_name='name_2', on_delete=models.CASCADE, blank=True, null=True) views.py @login_required def hotel_facilities(request, id): if request == 'HotelSingleRoom.objects.get(id=id)': hotel = HotelSingleRoom.objects.get(id=id) else: hotel = HotelDoubleRoom.objects.get(id=id) form = HotelFacilitiesForm() if request.method == "POST": form = HotelFacilitiesForm(request.POST) if form.is_valid(): data = form.save(commit=False) data.name5 = hotel data.save() return redirect('hotel:photos', data.id) context = {'form':form,} return render(request, 'hotel/facilities.html', context) I just tried this and of course it is not working... :) -
Django overriding the save method gives error
Disclaimer, I'm still new to a lot of concepts in Django so patiance please. So what I'm trying to do is the value of name from Counter model, assign it to the value of code from Order model. In the counter, I run a function that checks if the code year is 2020, then it gets me a value and concatinates that to make up the name of the Counter. Now when I run this code, it all fills up and instead of getting a value for the code, i get this as the value: django.db.models.query_utils.DeferredAttribute object at 0x04388250> Furthermore, I did some debugging, and when I ran a debug line on the save method in the Order model, it gave me this: queryset = {NameError}name 'queryset'is not defined. But I'm not sure what I need to do exactly. Any help would be appreciated, thanks. class Order(model.Models): code = models.CharField(unique=True) code_year=models.IntegerField def save(self, *args, **kwargs): self.code = Counter.name super().save(*args, **kwargs) class Counter(models.Model): name = models.CharField(max_length=10) value = models.IntegerField def save(self, *args, **kwargs): if Order.code_year == 2020: try: c_2020 = Order.objects.latest('id').id + 1 except Order.DoesNotExist: c_2020 = 1 self.value = c_2020 temp_value = f"P - {c_2020} - 2020" self.name = temp_value … -

How to cache a dictionary in Django?
I am using Django as my Webframework. I have a method that takes really long ~10 sec to complete. It returns a Dictionary which I then display in the templates. This method is called on a POST request after a button click. When the user reloads the page the View gets a GET request and all the results from before dont get displayed anymore. How can I somehow cache the Dictionary so I can even display it on a get request when the user once did the POST request? -

(python) Github Actions test selenium copy paste
I am testing my python application with e2e tests and use github actions as part of my CI. Normal selenium tests work totally fine. I added a click to copy functionality and want to test it via a unit test. So far I am using pyperclip to do this: import pyperclip link = pyperclip.paste() assert link == "target link" Locally on my machine (OSX) everything works fine. Unfortunately, I am not able to get this library working with ubuntu on github actions. I get this error: Pyperclip could not find a copy/paste mechanism for your system. Please see https://pyperclip.readthedocs.io/en/latest/introduction.html#not-implemented-error for how to fix this. I've checked the page but I am not able to get it working. Does someone know a way how to access the clipboard in github actions? -

How should I manage my images for my django app
Here I am once again asking a question that might seem stupid: I am new to web development. So far I've made some practice projects with Django and I've deployed two projects so far as github pages but they were simple static websites (no django). Now I'm making a web application for my mom's business with Django. I don't know what I should do with all the images I need for the website. In the past I have uploaded all jpg and png images to imgur and copied the link in my static websites html But now I have more images and I am going to pay for a server for them application. I have two types of images: Images that will always appear on the page. Because that's part of the design Images that the admin can upload when creating a new post for the page So my question is: Should I have all images in the statics folder for my application? And call them like this: <img src="{% static 'website/images/home-slider/myimage.css' %}"> And for the other images should I save a similar path in the database? I just have no idea if things should be done different for production -

How can I create a form with unknown number of columns and rows?
I don't know if I will be able to explain this very well, so please bear with me, and I will update where/when needed as much as I can. I have a Django app that is designed to take in data from users for products that we need to configure. The products are split into main categories of main products, which are then further split by customer. Main products have default settings, and customer products have SOME of these settings changed, plus some others not listed by the main product. Each customer may have multiple variations of the product too. Example of products: Main Product A | |-> Customer A Product A1 |-> Customer A Product A2 | |-> Customer B Product A1 |-> Customer B Product A2 Main Product B | |-> Customer A Product B1 |-> Customer A Product B2 | |-> Customer B Product B1 |-> Customer B Product B2 What I need/want, is a table for staff to enter the needed settings for a given customer, without the app knowing how many settings are needed, and how many customer products there are, in advance. Example: Setting Product A1 + Low Power TRUE Delayed Start 5 seconds … -

Why decorator @property return id in Django
In my models.py I have @property decorator - but it returns me id of model. I wrote method in this decorator but it is does not work: @property def replace_name(self): if not self.name: if self.middle_name: return self.full_name if not self.middle_name: return self.address My html template: {{ object.person.replace_name }} What does it wrong here?
