Django data handling in custom middleware

Django QuerySet not appearing in HTML file for PythonAnywhere Web App
I'm having a bit of trouble with this part of the DjangoGirls tutorial (about templates). Currently, my website is at chocoberrie.pythonanywhere.com. It's supposed to show a few posts inside the QuerySet, but the list is empty, and I don't know why (or how to fix it). 1) The QuerySet isn't loading at all in the HTML file. I followed the steps to import the Post model into views.py and add the QuerySet in the posts variable (the previous part of the tutorial). When I tried putting {{ posts }} in the HTML file (post_list.html), nothing appears in the QuerySet that loads on the page. 2) I don't know how to edit the database file on PythonAnywhere. This database file is supposed to be separate from the local db.sqlite3 on my computer (since db.sqlite3 is in the .gitignore file, it's not committed). I read about this here. I understand that this is useful to keep production changes from being displayed on the live website, but how I supposed to have this data on the PythonAnywhere side? What file am I supposed to edit on PythonAnywhere? Thanks for the help, I appreciate it! Here are my local files: urls.py from django.conf.urls import … -

Wagtail/Django App not serving images using DEFAULT_FILE_STORAGE storage backend
I have a wagtail app and using this guide I've managed to serve static files from an S3 bucket. I am trying to do the same thing for media files, however, changing DEFAULT_FILE_STORAGE and MEDIA_URL seems to have no effect on where uploads are stored, or the URLs rendered by templates.

Perform subqueries for each day in range
I building a 'airbnb clone' app on Django. The app has a flexible price system. Each landlord-user can save arbitrary number of prices which differ by priority and date range. Here is how it looks like (most of the fields skipped for the sake of simplicity): class PriceBlock(models.Model): price = models.DecimalField() priority = models.CharField(choices=PRIORITY_CHOICES) start_date = models.DateField() end_date = models.DateField() class Flat(models.Model): prices = models.ManyToManyField(related_name='flats') For example User created 3 PriceBlock instances with date values in some random month. p1 - has priority 1, price 100$ and dates from 1 to 3 p2 - has priority 2, price 200$ and dates from 2 to 5 p3 - has priority 3, price 300$ and dates from 4 to 6 To calculate price for flat from 1 to 6 days on this month we need to calculate price of PriceBlock with higher priority on each day. The problem is - I need calculate price for each flat in the ListView of all flats. Here's how I do it: class FlatQueryset(models.QuerySet): ... def with_block_full_price(self, start, end): days = get_days(start, end) # function returns list of days nums prices = {} for num, day in enumerate(days): prices[f'price_{num}'] = Subquery( PriceBlock.objects.filter(flats=OuterRef('pk')) .filter(start_date__lte=day, end_date__gte=day) .order_by('-priority') .values('price')[:1], … -

I have a custom User Model. I can successfully add user to it and want to add the relationship to a related model. It gives me no errors but does not link the user to the related field compusers in the company model. Basically I need it to after creating a user, also add the user to the related compusers field. This is the code I am trying in the view: self.object.compusers.add(self.object.id) The Model class Company(models.Model): user = models.ManyToManyField(settings.AUTH_USER_MODEL,related_name='compusers') name = models.CharField(max_length=265, blank=True) tel = models.IntegerField(blank=True, null=True) email = models.EmailField(max_length=265,blank=True) address = models.TextField(blank=True) postal = models.TextField(blank=True) regno = models.CharField(max_length=265,blank=True) vatno = models.CharField(max_length=265,blank=True) def __str__(self): return self.name def get_absolute_url(self): return reverse('nodisoapp:home') The View class AddStaffView(CreateView): form_class = forms.AddStaffMember success_url = reverse_lazy('nodisoapp:home') template_name = "scrty/addstaff.html" def form_valid(self, form): self.object = form.save(commit=False) self.object.password = get_random_string(length=8) self.object.save() self.object.compusers.add(self.object.id) return super(AddStaffView, self).form_valid(form) The form Class AddStaffMember(forms.ModelForm): usrtype = forms.ChoiceField(choices=[('Admin','Admin'),('Manager','Manager'),('Employee','Employee')],label="User Type: See below for descriptions" ) class Meta: model = get_user_model() fields = ("firstname","lastname","email","usrtype") labels = { "firstname": _("First Name"), "lastname": _("Last Name"), "email": _("E-mail"), } -
Django urls.reverse with argument
Stuck on this for a while: in Django pytest I am trying to do req = RequestFactory().get(reverse('app_name:app_view_name')) But I require the url to have '/[number]' at the end so that UpdateView will recognise the number and display appropriate form from model. In the browser the links and form submission all work fine, but I am unable to use reverse() in testing. I have tried: req = RequestFactory().get(reverse('app_name:app_view_name', args=[1])) and req = RequestFactory().get(reverse('app_name:app_view_name'), kwargs=['pk'=1]) but none of these work. I am simply trying to build the url with '/1' added at the end. Any help much appreciated.
