Python/Django button to redirect user depending on the actual site
I've searched for the best idea to clearly implement a button that redirects a user to the post creation page depending on the current URL but I still don't have a good solution. I have 1 same template for 3 pages. Each page has 10 categories (subpages). Maybe example: urls.py: app_name = 'forum' 1 category path('category1/, View.as_view(), name = category1 2 category path('category2/, View.as_view(), name = category2 1 category post creation path('category1/create-post/', PostCreateView.as_view(my_id=11), name = category1-new-post 2 category post creation path('category2/create-post/', PostCreateView.as_view(my_id=12), name = category2-new-post If the user is on the first subpage/category and clicks the button then redirect him to {% url 'forum:category1-new-post' %} If the user is on the second subpage/category and clicks the button then redirect him to {% url 'forum:category2-new-post' %} and etc 28x times (3 pages x 10 categories) I've tried to write something like this: {% if request.resolver_match.url_name == 'category1' %} button with href '{% url 'forum:category1-new-post' %}' {% elif request.resolver_match.url_name == 'category2' %} button with href '{% url 'forum:category2-new-post' %}' and etc 28x times. The code above doesn't seem good. Writing 30 ifs is not the best idea and i don't know how to handle it. For each subpage/category post creation i have … -
NoReverseMatch at /main/insert_num/ Django
I'm trying to make to make a django web app which has a form that asks a user to input a phone number and stores that number in a postgres database. The following code is giving me the error: NoReverseMatch at /main/insert_num/ Reverse for '' not found. '' is not a valid view function or pattern name.

why does Django returns BadHeaderError when adding a new line in my 'Contact' page's 'message' field
Everything works except when I add a new line via 'enter' in the "Message" field. It goes through if I don't add new lines in the message textfield. What am i missing here? Tried to solve this problem for 2 days, nothing similar on google. I feel like there could be the problem of my views.py config: def success(request): return render(request, 'home/success.html') def contact(request): if request.method == 'POST': form = ContactForm(request.POST) if form.is_valid(): # send email code goes here sender_name = form.cleaned_data['name'] sender_email = form.cleaned_data['email'] sender_phone = form.cleaned_data['phone'] sender_message = form.cleaned_data['message'] subject = "Enquiry: {0}".format(sender_message[:50]) message = "New message from {0}\n phone number: {1}\n email: {2}\n\n{3}".format(sender_name, sender_phone, sender_email, sender_message) recipients = ['john.smith@gmail.com'] sender = "{0}<{1}>".format(sender_name, sender_email) try: send_mail(subject, message, sender, recipients, fail_silently=False) except BadHeaderError: return HttpResponse('Invalid header found') return HttpResponseRedirect('success') else: form = ContactForm() return render(request, 'home/contact.html', {'form': form}) Any ideas? -
Data not passing to django template on DetailView
I have a model that should show data on the home page but isn't. I think the problem has to do with fetching data from an external API that also shows on the home page. `models.py` class Stats(models.Model): confirmed = models.CharField(max_length=20) recovered = models.CharField(max_length=20) death = models.CharField(max_length=20) def __str__(self): return str(self.confirmed) `views.py` import services # API comes from services.py class IndexData(DetailView): template_name = 'pages/home.html' stats = Stats.objects.all() def get(self, request): article_data = services.get_data() return render(request, 'pages/home.html', article_data) home.html {% for s in stats %} {{ s.recovered }} {{ s.deaths }} {{ s.confirmed }} {% endfor %} It should show: But is showing: -
"django_site" does not exist on migration
Earlier today I was having some problems with conflicting migrations for various reasons. I decided to just destroy the entire DB and start from scratch (we're pretty early in the project there is no harm in resetting everything). However, when I tried to get things back up and running with manage.py migrate I get this error: File "/Users/travis/Documents/venv/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) psycopg2.errors.UndefinedTable: relation "django_site" does not exist LINE 1: ..."django_site"."domain", "django_site"."name" FROM "django_si... ^ The above exception was the direct cause of the following exception: Traceback (most recent call last): ... return self.cursor.execute(sql, params) django.db.utils.ProgrammingError: relation "django_site" does not exist LINE 1: ..."django_site"."domain", "django_site"."name" FROM "django_si... ^ This seems to be a very common error and the main solutions I have seen (and tried) are: add SITE_ID = 1 to base.py; in my case, it's already in there.

Record IP Address with Form Submission Django
I am trying to use the django-ipware pacakge to record the IP address of someone submitting a form submission via Django. The form is a ModelForm. Here's the model: # models.py from django.db import models class Upload(models.Model): email = models.EmailField() title = models.CharField(max_length=100) language = models.ForeignKey('about.channel', on_delete=models.CASCADE, default='Other') date = models.DateField(auto_now_add=True) file = models.FileField() ip_address = models.GenericIPAddressField() Here is the form: # forms.py class UploadForm(forms.ModelForm): class Meta: model = Upload fields = ['email', 'title', 'language', 'file'] labels = { 'email': 'E-Mail', 'title': 'Video Title', 'file': 'Attach File' } The business logic for getting the IP address is pretty simple, but I've tried placing it in different locations with no luck. Where should I place the logic so it will be submitted along with the other form data? # views.py from ipware.ip import get_real_ip ip = get_real_ip(request) -
django calendar make first day sunday
Currently my calendar is formatted with Monday being the first day of the week. What I would like is for the first day to be Sunday.

Most efficient database design (models) for tracking daily object rankings in huge database
I am designing a Django project that needs to be able to track 1 million+ products and produce daily rankings for which product had the most total number of sales. I need to store and reference this historical ranking data and be able to retrieve rankings for any day in the past. Therefore, my models.py looks like: class Product(models.Model): product_name = models.CharField(max_length=200, unique=True) updated_at = models.DateTimeField(auto_now=True) sub_description = models.CharField(max_length=500, default='') class Rank(models.Model): class Meta(object): unique_together = ['pub_date', 'product'] pub_date = models.DateField(db_index=True) product = models.ForeignKey(Product, on_delete=models.DO_NOTHING) total_sold = models.IntegerField() My plan is to run a django management command script each day. The script will create a new Rank object for each Product in the database every day. Here is a simplified version of the script logic: now = datetime.datetime.utcnow().replace(tzinfo=utc) for prod in Product.objects.all(): try: rank = Rank.objects.get(product=prod, pub_date=now) print("Already updated for ", str(now)) except Rank.DoesNotExist: rank_value = prod_api.get(prod) rank = Rank(product=prod, pub_date=now) rank.total_sold = rank_value rank.save() Because it is possible for a user to request daily rankings while the management command is only halfway through adding new Rank objects for today, the following annotates were a bit tricky for me. I am returning the most recently updated Rank object for each … -
Django how to change the admin panel template
I am trying to change what is displayed when I click on a model in the django admin. For example if I have the model Book and then I go into the admin panel and click book, it will give me all the fields that I created the model with. But I want to edit that page that shows all that data. For example, if I click on the "Book" model in the admin panel and see my fields to edit, I want to put another bit of fields on the bottom from another model. Or maybe I want to put like a "Similar Books" list. Is it possible to edit this page? -

After setting up cookiecutter for Django, I get a ConnectionRefusedError for sign-up and sign-in
I'm working on a project using cookiecutter, but for whatever reason, I can't sign in or sign up.

ValueError at /books/results/
"Field 'id' expected a number but got 'results'." I'm getting this error while trying to use search filter over a list of books. It was working fine until I changed the Class-based view to Function based view. This was the Class based view earlier using the default DetailView class: class BookDetailView(LoginRequiredMixin,DetailView): model = models.Book template_name='book_detail.html' login_url='login' This is the new Function based detail view I changed to: @login_required def book_detail(request,book_id): model =models.Book book=model.objects.get(id=book_id) template ='book_detail.html' owner =CustomUser.objects.get(username=book.owner) return render(request,template,{'book':book,'owner':owner}) Independently when I'm trying to go to detail view, its working fine. But when I try to search using the 'book_search' view, its throwing this error. Previously search functionality was also working fine. @login_required def book_search(request): template ='book_list.html' model =models.Book query =request.GET.get('q') results =model.objects.exclude(owner =request.user).order_by('-available','-id') if query: results =results.filter(Q(title__icontains =query)) paginator = Paginator(results, 9) page =request.GET.get('page') try: books =paginator.page(page) except PageNotAnInteger: books =paginator.page(1) except EmptyPage: books= paginator.page(paginator.num_pages) return render(request,template,{'books':books,'query':query,'page':page}) It has something to do with the result set that the search view is returning a list of books while detail view only require just one id. -
