Django Search Form Errors When Adding to_form_field
Whenever I try to add to_form_field to subject and membership form fields, I get the following errors: ValueError: invalid literal for int() with base 10: 'Programming' ValueError: invalid literal for int() with base 10: 'Free' Field 'id' expected a number but got 'Programming'. Field 'id' expected a number but got 'Free'. URL without to_form_name: http://127.0.0.1:8000/courses/?name=&min_views=&max_views=&min_date=&max_date=&expertise=&subject=1&membership=1 URL with to_form_name: http://127.0.0.1:8000/courses/?name=&min_views=&max_views=&min_date=&max_date=&expertise=&subject=Programming&membership=Free I would like to be able to pass the actual string rather than the number in the URL for SEO purposes. When I leave to_field_name out of forms.py, there is no error and my search form filtering works. But it puts numbers in the URL which is undesirable. Views.py: class CourseListView(ListView): model = Course def get_queryset(self): qs = super().get_queryset() self.form = form = CourseForm(self.request.GET) if form.is_valid(): title_contains_query = self.request.GET.get('name') view_count_min = self.request.GET.get('min_views') view_count_max = self.request.GET.get('max_views') date_min = self.request.GET.get('min_date') date_max = self.request.GET.get('max_date') skill_level_query = self.request.GET.get('expertise') subject_query = self.request.GET.get('subject') membership_query = self.request.GET.get('membership') if title_contains_query: qs = qs.filter(title__icontains=title_contains_query) if view_count_min: qs = qs.filter(visited_times__gte=view_count_min) if view_count_max: qs = qs.filter(visited_times__lte=view_count_max) if date_min: qs = qs.filter(created_at__gte=date_min) if date_max: qs = qs.filter(created_at__lte=date_max) if skill_level_query: qs = qs.filter(skill_level=skill_level_query) if subject_query: qs = qs.filter(subject=subject_query) if membership_query: qs = qs.filter(allowed_memberships=membership_query) return qs def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = … -

How to update extended user profile in Django with one-to-one link?
I am trying to figure out how to extend the User model using a One-to-One relationship in Django. I'm creating a user Profile to hold extra information about the User. However, I am new to Django and do not understand how I update this user Profile. I want to add a UserProfileSerializer to the serializers file to update the Profile, how do I do this? And how do I call this in my views file? The closest information I can find is: def update_profile(request, user_id): user = User.objects.get(pk=user_id) user.profile.bio = 'Lorem ipsum dolor sit amet, consectetur adipisicing elit...' user.save() However, I do not understand how I can reference the user_id through my serializer class, or how I can pass through user_id from a request. Below is the User model serializer and views, and the Profile model. The profile model class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) pin = models.CharField(null=True, max_length=4, blank=True) birth_date = models.DateField(null=True, blank=True) security_question_1 = models.CharField(null=True, max_length=100, blank=True) security_question_2 = models.CharField(null=True, max_length=100, blank=True) security_question_3 = models.CharField(null=True, max_length=100, blank=True) # post_save is the signal received when a save event occurs in the User model @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): … -

Overwrite Django model __init__ method
The Ingredient model of my Django project has an IntegerField which declares if this ingredient stock is managed by weight, units, or litters. Although the database has its integer value I have to display its name. And instead of looping over every ingredient and setting its value, I thought it was better to overwrite the __init__ method of the Python class, but I don't get how. models.py: class Ingredient(models.Model): def __init__(self): super(Ingredient, self).__init__() if self.cost_by == 1: self.cost_by = 'Units' elif self.cost_by == 2: self.cost_by = 'Kilograms' elif self.cost_by == 3: self.cost_by = 'Litters' #...etc... So far I tried with this, but I'm getting the following error: __init__() takes 1 positional argument but 0 were given Which argument should I pass? -
Yet another: URL resolves, but in a Django template URL NoReverseMatch(es)
I have a Python3.7, Django3.0 situation involving a URL that Exception Type: NoReverseMatch Exception Value: Reverse for 'create' not found. 'create' is not a valid view function or pattern name. Your assistance in this matter is appreciated. After reading a gobsmack of other questions similar to mine, I'm guessing there is a typo I just can't see. Maybe you can see it :D Many mahalos. library(app)/urls.py: from django.urls import path from . import views app_name = 'library' urlpatterns = [ path('', views.IndexView, name='index'), path('create/', views.CreateLibraryView, name='create'), ] mycastle(project)/urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('library.urls')) ] The views are wholly unremarkable: def IndexView(request): library_list = Library.objects.all() return render(request, 'library/index.html', {'library_list': library_list}) def CreateLibraryView(request): library_list = Library.objects.all() return render(request, 'library/create.html', {'library_list': library_list}) and a base template that just wants to connect in a meaningful way: <div class="page-header"> {% if user.is_authenticated %} <a href="{% url 'create' %}" class="top-menu"> <i class="fa fa-rocket"></i> Create a new library! </a> {% endif %} If I take the {% url 'create' %} line out - all the URLs resolve properly and happiness abounds. -
Can you set the value of a third option URL path() dictionary with a URL template tag parameter in django?
I need to pass an extra param to a url, but don't want to add it to the url pattern. Reading the django docs, I came across this, which is a bit like: urlpatterns = [ path('blog/<pk>/', views.year_archive, {'foo': 'bar'}), ] Sounds like what I need, but is there a way to set the value of 'bar' with a url tag, something like: data-url="{% url 'name_of_view' pk=obj.id foo=obj.bar %}" or... data-url="{% url 'name_of_view' obj.id obj.bar %}" or... ??? Also tried things like: path('blog/<pk>/', views.year_archive, {'foo': <bar>}), path('blog/<pk>/', views.year_archive, {'foo': self.bar}), #don't know why I think that would work Of course none of that works. I can pass 'obj.bar' through its own url pattern which is easy enough, but this breaks some other dependent code. Looking for another way, and the third option url dictionary seems promising if I can get it to work but so far can't set the value from the template. -
Getting error TemplateDoesNotExist at / when loading home page template - Django + Bulma, Sass
I'm a Django beginner and have been trying many solutions to this with no luck. Trying to use Sass to customize the Bulma framework in a Django site.

How to send scraped data into postgresql database
I have a python file in my Django project which scrapes 10 names from a website. I want to store these 10 names in a postgresql database. Below is the python file. import requests import urllib3 from bs4 import BeautifulSoup import psycopg2 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) session = requests.Session() session.headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36"} url = 'https://www.smitegame.com/' content = session.get(url, verify=False).content soup = BeautifulSoup(content, "html.parser") allgods = soup.find_all('div', {'class': 'god'}) allitem = [] for god in allgods: godName = god.find('p') godFoto = god.find('img').get('src') allitem.append((godName, godFoto)) print(godName.text) How do I need to approach this, I've made a class in models.py named GodList. But as soon as I try to import it I cannot run the scrape script anymore. Am I aproaching this wrong? I have the postgresql database connected to Django and it works.

INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'demo', 'app', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ROOT_URLCONF = 'demo.urls' TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['/usr/local/lsws/Example/html/demo/app/templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] Can anyone help me?! -
cached function vs non-editable field django
I have a model Submission, users submit numbers to my server and I store them. I'm interested if the numbers are even. I can think of two solutions. creating a non-editable field and calculating it when I'm saving my Submission method. creating a cached function in the Submission model that would see if the number is even. I am also interested in statistics such as knowing how many people have submitted even numbers etc. Could you please tell me which choice is best practice in what case and for what reasons? P.S. I've simplified the problem, it's not exactly if the numbers are even, my problem is if the user has picked the correct answer(s) from a test.
