Django "NoReverseMatch: Reverse for 'ads.views.AdListView' not found" while doing Test
I implemented some tests to check the status code of some pages, but this one with the reverse function throws me the error: django.urls.exceptions.NoReverseMatch: Reverse for 'ads.views.AdListView' not found. 'ads.views.AdListView' is not a valid view function or pattern name. Reading the documentation and some answers on stackoverflow I'm supposed to use either the view function name or the pattern name inside the parenthesis of the reverse function, but none of them seems to work.

How to configure a server on raspian with django, apache2, mariasql, vhosts, pipenv
I am trying to set up a webserver, and have made some steps towards setting it up but I have hit a hurdle that maybe some one can help me with. I am getting the following error "This site can't be reached". Checking the connection Checking the proxy and the firewall. I have only done this setup once before and it was ages ago, but have exhausted my documentation at the time that I did it. And any scraps for information would be most helpful. Heres my setup and steps so far, some steps are for later e.g. certbot etc. What I am currently trying to do is show domain.co.uk in the browser after setting the /etc/hosts file.

Setting up VS Code for use with Django, Apache, virtualenv on a remote server
we have a django project on a development server which is running within a virtual environment. I was hoping to be able to use VS Code for development from my local PC, but I am not sure if I am able to or not. It seems like something that would make sense to do! I think I have managed to set the interpreter as the virtualenv on the server using UNC paths and have activated it, but when I try to run manage.py to create a new app, I get No module named 'django' which perhaps suggested the virtualenv hasn't activate properly? Is it possible to use VS Code in this way? thanks, Phil -

Min distance of one point to set of points Django ORM
I am trying to calculate minimum distances of one point to set of points. For example if there are 3 places A, B, C in the set and the wanted place is D, I want min(dist(A, D), dist(B, D), dist(C, D). Here is my place model: class Place(models.Model): latitude = models.FloatField(blank=False) longitude = models.FloatField(blank=False) Here is my query which seems not to work: places_with_distance = Place.objects.annotate( distance=( Subquery(places_set.annotate( distance_to_place_in_set=( Min( (F('latitude') - OuterRef('latitude')) * (F('latitude') - OuterRef('latitude')) + (F('longitude') - OuterRef('longitude')) * (F('longitude') - OuterRef('longitude')) ) ) ).values('distance_to_place_in_set')))).order_by('distance') The problem is that the distance gets calculated only for the first item of the places_set(e.g. only dist(A, D) but not dist(B, D), ...). Thanks! -

What is more flexible way to organize User authentication model in Django?
I've started working on a new project and I would like to know what is more flexible and changable (improvable) way to work with User model? At first I want to make my project oriented towards employees of the company to allow them manage products and other entities. And then I want to expand the project by letting customers to register in the system and buy stuff. But of course I want employees and customers to have different fields and restrict customers from having access to certain parts of the system. Django offers two ways of dealing with Users: it's either Substituting a custom User model or Extending the existing (default) User model. I can't decide what way to go to have two kinds of users in the future. -
My Django code (forms and models) works just fine, but It's definitely a bad choice for large amounts of data. Would appreciate suggestions
this code works just fine when registering users and adding them to the database. With additional code in the template, it also shows the users that their chosen username/email already exists pretty well. However I am mostly certain that this code's quality is very bad, since It woudn't work well with large databases, since I search for all the users and their usernames/email. Then again, I don't know how to add better validation. I decided to add these validators(passwords excluded) because, unique=True in models have no effect on the forms. What I mean is, before these codes, if I registered with the same username and email over and over, if the passwords matched, the last password that I entered got added to the database(user number stayed the same), but form was considered valid (I think) and It didn't show any errors to the user. This is the best I came up with, but I'm pretty sure it's a bad one. I am taking any suggestions, what other kind of validation can I add to fix the mentioned problem. I thought unique=True would fix things, but apparently it's not enough. Note that I am also a beginner and if this question … -
