OperationalError at / no such column:core_item.brands_id
I am having a tricky database problem. I have a set of categories that display on the nav bar, once you click on those categories, there is a filter called brand, and this brand filter is supposed to take you to a page where they have products under that category (e.g. makup) and display those items.

How to get the result of a textfield in django?
i am making a python editor, and i have a model called NewJax. In this model, i have a field called space. The space field executes the python code i typed in there. for example, if i did print('hello') in the space field, it should take me to a detail page, and return the result. Which is hello. but when it takes me to the details page for now, it results in None. Could you someone please let me know, how this should execute? models.py class NewJax(models.Model): title = models.CharField(max_length=60) description = models.TextField(max_length=140) space = models.TextField() user = models.ForeignKey(User, on_delete=models.CASCADE) date_created = models.DateTimeField(default=timezone.now) class Meta: ordering = ['-date_created'] verbose_name_plural = "New Jax" def __str__(self): return str(self.title) forms.py class CreateNewJaxForm(forms.ModelForm): class Meta: model = NewJax fields = ('title', 'description', 'space') widgets = { "title": forms.TextInput( attrs={ 'class': 'form-control', 'placeholder': 'name your jax' } ), 'description': forms.Textarea( attrs={ 'class': 'form-control', 'placeholder': 'add a brief description for jax', 'rows': 4, } ), 'space': forms.Textarea( attrs={ 'class': 'form-control', } ) } views.py def create_new_jax(request): if request.user.username == "Assasinator": logout(request) return redirect('banned_user') if request.method == "POST": form = CreateNewJaxForm(request.POST or None) if form.is_valid(): title = form.cleaned_data.get('title') description = form.cleaned_data.get('description') space = form.cleaned_data.get('space') obj = form.save(commit=False) … -
Django+Rest and later React without Docker?
I would like to ask an advice... I did the project with Django+Rest... But never thought about adding to them React... But I would like to do React... I did it, but it runs as a local version... So I have Django which runs as https and React which runs as http://localserver:3000... Which is not really good... I went through about 6 or 7 tutorials... But they all using Docker... To use Docker I have to restructure the project completely... When I structured project first time I didn't think about React. Now generally the structure is like this: -files and folders for Djago -frontend files and folders for React -in the root of the server: /etc... files and folders for gunicorn and nginx So the question is: Is it possible to serve React, only by tuning gunicorn and nginx, without changing the site itself... So url will be something like this: https://address/home/django_url https://address/home/React_url Similar to Rest api, which I run like so:https://address/home/api/Rest_url Or so React will be as frontend based on the Django as backend... I'm kind of confused about if I can do it and how... -

Since locker and user are unique identifiers for the member, My model structure is … -
open_note() missing 1 required positional argument: 'docid'
I appreciate that this question has been asked multiple times before, and I have looked at basically all of the answers and the official documentation for django, but I still can not figure out why I am getting the Exception Value of: open_note() missing 1 required positional argument: 'docid'. I am trying to get the page to display the selected document from the database, when it loads it should show the title and the content, along with an edit and delete button (neither of which function yet, but they're not important right now). The request url is http://localhost:8000/notes/open-notes/?docid=1, and it leads to the error mentioned above. If I change my urls.py path to path('open-notes/<int:id>/', views.open_note, name='open-notes'), then the error I get instead is Reverse for 'open-notes' with no arguments not found. 1 pattern(s) tried: ['notes/open\\-notes/(?P<id>[0-9]+)/$'] which I assume is because the id isn't actually an int and needs converting in the views.py, or I need to use a different converter in the urls.py. Or equally entirely possible, I've misunderstood the other answers in which case I apologise for asking the same question that already has an answer I should be able to implement. I am relatively new to django and … -
How to use for loop counter with a nested if loop?
I created a for loop with a nested if statement for counting specific types of customers in my Django project. What I need is the final number of the for loop counter. I try: {% if forloop.last %} {{ forloop.counter }} {% endif %} But it displays nothing. But when try just {{ forloop.counter }} it displays 2 number. One of them is what I want but the other one is all for loops I think. How can I solve this problem? list.html {% for customer in customer_list %} {% if customer.country.country_name == country %} {% if customer.risk_rating == "Low Risk" %} {% if forloop.last %} {{ forloop.counter }} {% endif %} {% endif %} {% endif %} {% endfor %} views.py def test_customer_list(request): current_user = request.user userP = UserProfile.objects.get_or_create(username=current_user) customer_list = Customer.objects.filter(company=userP[0].company) countries = Customer.objects.values_list('country__country_name', flat=True).distinct() country_links = Country.objects.filter() context = { 'customer_list': customer_list, 'countries': countries, 'country_links': country_links } return render(request, 'test.html', context) -
NoReverseMatch error on password reset. The error only occurs on remote server and NOT on the local server

Django class based views- handle redirect to the same view, add new context
After POST request I want to redirect user to the same view, adding something to the context. I have no idea how to do it. I tried using get_context_data(**kwargs) but I think I don't really understand the concept. If I do not add anything into context I simply redirect to the same view, which sounds dumb but works. Here's my code: (the class is "home.html" view) class FilteredZamTableView(LoginRequiredMixin, SingleTableMixin, FilterView): table_class = ZamTable template_name = 'home.html' paginate_by = 10 filterset_class = ZamFilter def post(self, request, *args, **kwargs): if request.POST.get('accept_zam'): try: ... return redirect('home') except Exception as e_msg: context = self.get_context_data(**kwargs) context['error'] = e_msg return render(response, "home.html", context) I get this error msg at self.get_context_data(**kwargs) django.urls.exceptions.NoReverseMatch: Reverse for 'home' with keyword arguments '{'e_msg': AttributeError("'FilteredZamTableView' object has no attribute 'object_list'")}' not found. 1 pattern(s) tried: ['$'] -

How is the UserAttributeSimilarityValidator supposed to be used in Django?
I am testing a REST API I wrote in Django, but this validator does not work as intended. I read the docs on this, but I need more than a description; I need a working example. I have it defined in settings.py as is the default. # my_app/settings.py AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, ... ] However, when I run the test, I get an unexpected and undesired success. # api/authentication/tests.py body = { 'username': 'frank', 'email': 'frank@example.com', 'password1': 'frank@example.com', 'password2': 'frank@example.com', } response = self.client.post(url, body, format='json')) self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST) > ./manage.py test Creating test database for alias 'default'...

String value for decimal field doesn't throw ValidationError in view but works fine in shell
I created test project to figure this out. Here is the form: class PaymentForm(forms.Form): amount = forms.DecimalField(max_digits=2, decimal_places=2, required=False) Everything works as expected in shell: >>> from testapp.forms import PaymentForm >>> f = PaymentForm({'amount': 'a'}) >>> f.errors {'amount': ['Enter a number.']} >>> f.is_valid() False But if I enter string value in a template and submit the form, it doesn't give any error messages at all and 'it is valid' is being printed. def add_payment(request): if request.method == 'POST': payment_form = PaymentForm(request.POST) if payment_form.is_valid(): print('it is valid') else: payment_form = PaymentForm() return render(request, 'testapp/add.html', {'payment_form': payment_form}) When i make the field required, the form gives the expected 'Enter a number' and the view - 'Required field' error message. Any ideas how to make it work? Is this how django forms supposed to work? Because i couldn't find anything by googling. -

defining all columns in django values just to get foreign key value
I am working on a Django app and I have a model containing about 60 columns with few ForeignKeys For e.g. class Company(models.Model): name = models.CharField(max_length=100) city = models.CharField(max_length=100) address = models.CharField(max_length=100) user = models.ForeignKey(User, on_delete=models.CASCADE) # and many more rows I need to show all data in DataTable. Company.objects.all().values() To get the username from user column, I need to call it as Company.objects.all().values('user__username') But this doesn't makes sense to me, Just to get the username, I will have to define all columns of Company model Company.objects.all().values('name', 'city', 'address', 'user__username') I was already getting 'name', 'city', 'address' with .values() But to get username, I have to define them explicitly. This is okay with small models, but this approach becomes tidious and error-prone with bigger models. I'm sure there must be a better way to do this that I dont know. Any help would be appreciated. -

How retrieve Discord messages to my website?
I currently have a Python/Django platform and a Discord community. I would like to get the messages of a channel to convert them into notifications on the site. Obviously I consulted the Discord doc but I really have trouble understanding.

I am scratching my head to stop the first triggering. settings.py CELERY_BROKER_URL = "redis://localhost:6379" CELERY_RESULT_BACKEND = "redis://localhost:6379" CELERY_BEAT_SCHEDULE = { "fill_db_daily": { "task": "agendanotification.tasks.fill_db_daily", "schedule": crontab(hour=0, minute=1), }, "articles_email_daily": { "task": "agendanotification.tasks.articles_email_daily_prod", "schedule": crontab(hour=0, minute=30), } } In tasks.py: @shared_task def fill_db_daily(): call_command("fill_db", ) @shared_task def articles_email_daily_prod(): call_command("articles_email_prod", ) -
500 error when deploying Django app to Heroku with no obvious error messages
I am trying to deploy my Django app via Heroku and keep receiving a 500 error. I'm new to Django so am not really sure what could be going wrong as I've followed a tutorial online pretty closely, but I've obviously mucked something up somewhere. I've looked at the logs and it doesn't really tell me anything... at least nothing that I can decipher. Thanks to anyone who's able to translate this into English. 2021-03-24T11:09:44.413513+00:00 heroku[web.1]: State changed from starting to up 2021-03-24T11:09:47.222339+00:00 heroku[router]: at=info method=GET path="/" host=thediamondseeker-2.herokuapp.com request_id=19a272b0-7efa-43d5-bbd1-8e28a70cb43a fwd="94.1.111.13" dyno=web.1 connect=1ms service=985ms status=500 bytes=410 protocol=https 2021-03-24T11:09:47.218908+00:00 app[web.1]: 10.29.126.3 - - [24/Mar/2021:11:09:47 +0000] "GET / HTTP/1.1" 500 145 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 11_2_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36" This is my settings.py """ Django settings for diamonds project.

Authorization Headers is missing using c# client
I am developing a RESTFUL API using django-rest-framework. And for Authorization I choose to use Token Authorization (not JWT). Below is what I tried: Using POSTMAN (Works) headers: Authorization: Token 329367424fd30a876ccff05dbc5a18d86fe7158c Using C# Client (no working) HttpClient client = new HttpClient(); client.DefaultRequestHeaders.Add("Authorization", "Token 329367424fd30a876ccff05dbc5a18d86fe7158c"); await client.GetAsync(<url>) // Authentication credentials were not provided. After I debug and override TokenAuthentication function, I realize that Authorization headers is being removed if requested from C# Client. I saw a lot of question are being asked related to this problem, and the solution is adding WSGIPassAuthorization On I am not sure where should I add above line wsgi.py import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'nusames_core.settings') application = get_wsgi_application() FYI: I am planning to use gunicorn as my webserver, also I need it work locally (I am not using venv) Question: is there any workaround for my local env in order to make it works on c# client, and is there any best practice for production env? -
