get_object_or_404(), handler404, Http404 response. How do these things works?
Could you help me with something in Django, please?

How to attach user to request object
I'm using JWT for authentication in a django rest framework. It works like this: Creating a JWT token token = jwt.encode(payload, os.environ.get('SECRET'), algorithm='HS256') Sending the JWT token as a cookie with the httponly flag response.set_cookie(key='jwt', value=token, httponly=True) To verfiy that user is logged in any view I look for the cookie and decode it. The problem is that it wont use permission classes for the request object. I would like to know how I can do that. -

Django. Error writing database from csv via custom commands

Django SearchRank not taking full text search operators into account
I'm trying to add a new endpoint that does full text search with AND, OR, NOT operators and also tolerates typos with TriagramSimilarity. I came across this question: Combine trigram with ranked searching in django 1.10 and was trying to use that approach but SearchRank is not behaving as I'd expect, and I'm confused about how it works. When my code looks like the basic implementation of full text search the negative filter is working fine @action(detail=False, methods=["get"]) def search(self, request, *args, **kwargs): search_query = request.query_params.get("search") vector = SearchVector("name", weight="A") query = SearchQuery(search_query, search_type="websearch") qs = Project.objects.annotate( search=vector, ).filter( search=query, ) return Response({ "results": qs.values() }) But I need to implement this using SearchRank so I can later do some logic with the rank score and the similarity score. This is what my code looks like annotating for rank instead of using the tsvector annotation: @action(detail=False, methods=["get"]) def search(self, request, *args, **kwargs): search_query = request.query_params.get("search") vector = SearchVector("name", weight="A") query = SearchQuery(search_query, search_type="websearch") rank = SearchRank(vector, query, cover_density=True) qs = Project.objects.annotate( rank=rank, ).order_by("-rank") return Response({ "results": qs.values() }) And the response looks like: The rank given to the document named "APT29 Attack Graph" is 1.

How to link an automatically updating model object with Django Template Language
I'm making a blog, on the index page I have a list that links every single blog post with some details about it <ul> {% for post in object_list %} <li><a href="{% url 'article_detail' pk=post.pk %}">{{ post.title }}</a> - {{ post.author.first_name }} {{ post.author.last_name }}<br/> {{ post.summary }}</li> {{ post.adventure_date }}<br/> {% endfor %} </ul> </div> Now what I want is on the home page to have a featured article section that will automatically update with the two most recently posted articles without having to manually change the code every time the posts are added. I'm struggling to come up with a solution to this, I'm thinking that I would create another variable in my model that was like featured = BooleanField(default=True) But I'm not sure how the true or false would be automatically updated without me going into django admin and manually checking the boxes each time it needed updated -
How to run tasks in django?
I have a Dynamic programming algorithm that takes 2 arrays as an input and returns an array as an output (The arrays are fetched from my django model). I usually just write the algorithm in the view Example: #Model class input(models.Model): arr1 = ArrayField(models.CharField( null=False, max_length=200), blank=False) arr2 = ArrayField(models.CharField( null=False, max_length=200), blank=False) #View @api_view(['GET','POST']) def process(request): arr1 = ... # fetch arr1 arr2 = ... # fetch arr2 def my_algorithm(arr1 , arr2 ): ... ... return arr3 arr3 = process(arr1,arr2) ... ... return Response("Success") There is a tool called celery that does asynchronous task queue/job but it doesn't support windows anymore. What's the alternative or how can i execute the algorithm as a task and call it in the view? -

Offline deployment of python scypy and django
I've got a django/pandas/scipy application. I need to deploy them on a Windows Server 2012 machine without Internet access. So, I can't make a pip install in that machine. Furthermore, to install numpy, scipy and more, some of the libraries need to compile some libraries like openblas and more, so deployment is a nightmare. You need too many things to do for this deployment. Docker is not an option. I've got a VM right now, but I want to get rid of it. Is there any posibility to encapsulate a python - scipy to make a deployment on a machine without making it a real nightmare? -

Can I somehow tell the template processor to validate sensorname first and then values|json_script:xxx? -
Django project - JS not loading after moving it out of HTML to own file in static folder
Here is my folder organization When i had the JS directly in the HTML file, everything worked as expected. Since I moved it to a spots.js file, it doesn't load or appear in the network tab, but i can reach it by going to file location in the server. I am in Debug mode. In my settings.py I have: STATIC_URL = '/users/static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] STATIC_ROOT = os.path.join(BASE_DIR, 'var', 'static') In my urls.py, I have: urlpatterns = [ path('', home, name='users-home'), path('register/', RegisterView.as_view(), name='users-register'), path('profile/', profile, name='users-profile'), path('select-spots/', select_spots, name='select-spots'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) In my views.py I have: @login_required def select_spots(request): spots = [] with open('spotscsv.csv') as csvfile: reader = csv.DictReader(csvfile) for row in reader: spots.append({ 'name': row['name'], 'latitude': float(row['latitude']), 'longitude': float(row['longitude']), }) return render(request, 'users/select_spots.html', {'spots': spots}) And in my select_spots.html, I have: {% extends 'users/base.html' %} {% load static %} <script src="{% static 'myapp/spots.js' %}"></script> I have tried so many different variations but it still doesn't load on page. Do you know why not? I tried changing the spots location, i tried collecting static, I tried different code. -

Python - Creating two models with 1-1 relationship in a same model.py file (hierarchy problem) in Django
Hey I'm facing this problem when I want to create 1:1 relationship IDK if I'm missing something here or what am I doing wrong here in one app.model.py I'm trying to create 2 models like below : class Manager(models.Model): user_id = models.ForeignKey('BeautySalon.Salon',on_delete=models.DO_NOTHING) #FK businessL_id = models.BooleanField(default = False, blank = False) salon_id = models.ForeignKey(Salon,on_delete=models.DO_NOTHING) #FK class Salon(models.Model): # name, manager_id--Manager, city_id--City, address, tell, description, starting hour , closing hour, PTG, rank--Rank name = models.CharField(max_length=200) manager = models.ForeignKey(Manager,on_delete=models.DO_NOTHING) # FK city = models.ForeignKey(City,on_delete=models.DO_NOTHING) #FK address = models.TextField(null = False, max_length = 1000) tell = models.CharField(max_length=24) description = models.TextField(null= False, max_length = 1000) strHour = models.TimeField() clsHour = models.TimeField() PTG = models.BooleanField(default = False, blank = False) rank = models.ForeignKey(Rank,on_delete=models.DO_NOTHING) #FK but when I try to make migrations I get this error Field defines a relation with model 'Salon', which is either not installed, or is abstract.

Using class-based views save a form with 2 related models (via foreign key)
WANT TO DO using CreateView I launch an hmtm page containing a form. This page has had two embedded forms sent in like {{address}} and {{ship}}. The ship model has a foreign key linking it to the address table address_id. I can do this easily using function-based views, but I want to do it via class-based. I create my models, then I do something like this in the view that launches the html page: context = { 'address_form': AddressForm(), 'ship_form': ShipForm(), ) } return render(request, 'app/registration.html', context) The html looks sommething like this: ` {{ address_form }} {{ ship_form }} <input type="submit" value="Register"> ` When I click on submit, the form does connect to the database BUT it tries to save the ship form but it fails because it doesn´t have the address_id and of course, the reason is that the address_form could not be saved first, and this is what is blocking my progress. I know I can do ´some´ manipulation inside the CreateView that launched the html page, like in here def form_valid(self, form): # This method is called when valid form data has been POSTed. but there is no way I can reach the address form, it … -
Django approach for simple app structure?
I'm back to coding after almost 20 years working as a manager. Decided to play with python as I like the language started with some simple desktop apps and now I want use django and do some web development. I'm creating a series of small apps to help me with daily stuff at the company (time management, reading logs, creating slides based on those logs etc. Now question is: Django has a "front end" section and an "Admin" section. If I'm creating that kind of apps what approach should I go for? Develop everything in the Admin area or do that in the front area and save the admin if I need to create some configurations and stuff? I will use authentication for it in case this can be a issue. No access if you dont have an user and password that will be created by me. No self registering Guidance how to add an app to django the best way to suit my needs without loosing the power of the framework
