Python automation or Python for web?
I have a doubt: Is it recommended to learn Python for the web and Python Automation at same time? Or is it better to focus on just one area? I'm a programming beginner :D ------------------------------------------------------------- -
Store for loop queryset into one
I currently have an array with multiple objects. The for loop does a queryset based upon the array objects using a for loop of a model. search_post = ["1990", "2023"] for query in search_post: vehicle_result = Vehicle.objects.filter( Q(title__icontains=query) | Q(details__icontains=query) | Q(year__icontains=query) | Q(notes__icontains=query) ) print('vehicle_result: %s' % vehicle_result) The issue I'm having is when the array has multiple items it's going through the for loop for each object and it's outputting each objects result. Only the last object result is retained if I call this variable elsewhere in the code. Example Output: vehicle_result: <QuerySet [<Vehicle: BMW>]> vehicle_result: <QuerySet [<Vehicle: Toyota>, <Vehicle: Mercedes>, <Vehicle: Honda>]> I want to store/combine them all into one variable - prevent losing all the results (right now only the last one is retained I guess because the variable is overwritten) How can I achieve? -

how to render URL patterns in Django with multiple apps
I am trying to build a booking system, using Django. I have multiple apps and rendering the urls patterns has been difficult to understand and i have found the documentation little help when you have multiple apps. Here is my core app urls: urlpatterns = [ path('admin/', admin.site.urls), path('', include('review.urls'), name='review_urls'), path('accounts/', include('allauth.urls')), path('bookings/', include('booking.urls'), name='booking_urls'), ] The booking app urls: urlpatterns = [ path('booking', views.customer_booking, name='booking'), path('display_booking', views.display_booking, name='display_booking'), path('edit_booking/<booking_id>', views.edit_booking, name='edit_booking'), ] I am trying to render my edit_booking view: def edit_booking(request, booking_id): booking = get_object_or_404(Booking, id=booking_id) if request.method == "POST": form = BookingForm(request.POST, instance=booking) if form.is_valid(): form.save() return redirect('display_booking') form = BookingForm(instance=booking) context = { 'form': form } return render(request, 'edit_booking.html', context) where it is being called: <a href="/edit_booking/{{ booking.id }}"> <button>Edit</button></a> I tried adding bookings/ into my edit button but this is requesting a page with bookings/bookings/edit_booking/7. without it, it is just requesting the endpoint edit_booking/7 -
Docker-Compose - Frontend service cannot use endpoint from backend
Context I am currently working on a multi-container project involving react, django, and (eventually) several datastores all containerized and tied together with docker-compose. This is all developed within vscode devcontainers. The host operating system is Windows 11. Problem I can make requests to my Django API via the browser (and Django's API web interface). However I cannot make requesets to the API via the frontend service. Using the javascript fetch api, I am unable to make requests to any of the following localhost:8000 (NOTE: Many tut's say this should function just fine) 0.0.0.0:8000 (NOTE: This will at least throw a NS_ERROR_CONNECTION_REFUSED error, which is still unsolvable) host.docker.internal:8000 192.168.99.100:8000 172.24.0.2:8000 What I've Tried Proper CORS configuration with Django Ensuring all appropriate ports are exposed and forwarded within docker Re-implementing the entire project and basing it off of some other halfassed tutorial.

How to break a long line of html code into multiple lines as "\" will do in python and C/C++
Suppose that I have the following code, <p>aaa<a>bbb</a>ccc</p> the rendered web page will be like this However, when the text "aaa", "bbb", "ccc" becomes pretty long, I want to split this single line into multiple lines for readability, like <p> aaa <a> bbb </a> ccc </p> But the rendered web page will be like There are whitespaces between two blocks of text. How can I make these lines work as the single line mentioned before. In python or C/C++, I can simply use "\" to notify the consecutive lines should be treated as a single line. Is there a similar funtionality in html file? Besides, as I'm using django template system, I tried the django official tag "spaceless". According to django's doc, "spaceless" tag should remove the whitespace between html elements. But in this case, the whitespace between two blocks of text remains. I get pretty puzzled about this. Thanks for any help! I tried to ask chatgpt, github copilot and search on google. But I found no functionality in html that can make consecutive lines work as a single line. A similar functionality to "\" in python and C/C++ which inform compiler to treat consecutive lines as a single … -
Django Passkeys and NextJs
I would like to create an app based on Django and NextJS 13 that uses an authentication system using Passkeys. I have seen that there is a django package for passkeys but it seems not to work properly, or at least following the documentation it is not explained correctly with implement the system if you use an external framework like NextJS. I am therefore looking for a solution that will allow me to use passkeys as my login system. -
How to add permissions from URL path parameter to DRF ViewSet?
I have an app that uses url paths like the following: account/<ACCOUNT_PK/project/<PROJECT_PK>/ When using Django permissions, the permissions of the last parameter (in this case project) are checked, but also want to ensure permissions are checked for Account too. curl -s -u test:password \ -H 'content-type: application/json' \ -X POST -d '{"name": "new_project", "account": 3}' \ 127.0.0.1:8000/account/3/project/ In this example I need to check permissions for both the data given in the request, and the parameters in the URL. I have solved this by creating a valid_account method for the serializer class, and also a custom permission inherited from rest_framework.permissions.BasePermission, but it is very dependent on paths not changing. Is there an option that I'm missing or third party package that can do this? I have tried different permissions classes, or adding app.change_account to permissions_required in the ProjectViewSet, but only get errors. -

django simple history customising Base Class
I would like to start tracking changes made to a model using django-simple-history. I have a big model but would only need to track the history of a couple fields. I could use the exclude_fields parameter, but as the model gets larger, I do not want to manually keep on adding items that need to be excluded. I would like the basemodel history returns to be only the selected fields (bonus if history is only saved when one of these two fields changes, but not required). I have the following big model where I need to start tracking 2 fields: class Organisation(models.Model): .... lots of other fields balance = models.DecimalField( max_digits=15, decimal_places=2, default=Decimal('0.00')) costs = models.DecimalField( max_digits=15, decimal_places=2, default=Decimal('0.00')) history = HistoricalRecords() # only want to save history on fields balance and costs # basemodel that needs to be saved by history class OrganisationHistoryTrackedFields(models.Model): balance = models.DecimalField( max_digits=15, decimal_places=2, default=Decimal('0.00')) costs = models.DecimalField( max_digits=15, decimal_places=2, default=Decimal('0.00')) -

Accessing MySQL database with Django
Apologies in advance if this type of question already exists with a solution. I have been trying to get this solved for about 2 weeks now. So I had a Django project, which initially used the default Django database : SQLite3. I was able to access that database using /admin with the localhost, with 'admin' as password and username. I shifted the database to MySQL and everything was transferred properly, but I am not sure how to access the data using the /admin now. What should I enter in the username and password section? I have tried every possible combination with 'admin', database name, username, hostname and password which is provided in the settings.py when you change database. For reference, this is what the database section of my settings.py looks like DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'project', 'USER': 'root', 'PASSWORD': 'mysql-password', 'HOST': 'localhost', 'PORT': '3306', } } -

Problems with Django Websockets
