Run function on loading DetailView in Django
I would like to execute a function immediately upon loading a DetailView. Specifically, I have a Market model, and when users land on a DetailView using that model, I want the current_price on the relevant market to be saved in the most_recent_price feature of the relevant user. Here's what I have right now, which isn't doing anything - I don't get any error message or anything, it simply doesn't get executed: class MarketDetailView(LoginRequiredMixin, DetailView): model = Market template_name = 'question.html' login_url = 'login' def set_current_price_for_user(self, **kwargs): pk = self.kwargs['pk'] market = Market.objects.get(pk=pk) user = request.user user.most_recent_price = market.current_price I feel like I'm missing something basic here. What am I doing wrong? -

How to generate coverage reports programmatically using Coverage.py?
At present, I am generating coverage reports via coverage.py, by giving the coverage command which would thus generate an HTML report.

Django Serve Special files like favicon and manifest
How can I serve a directory as the default in Django? I build a django/react application. Got it all set up with uWSGI. Static files for both react and django working (using whitenoise for multiple static directories). But files like /favicon.ico and /manifest.json in the index.html built from react return a 404 error because they don't exist. How can I get django to attempt to serve files in the same directory as index.html if everything else fails? Currently I serve index.html by doing the following in Django: In myproject/urls.py: urlpatterns = [ path('', index, name='index'), path('favicon.ico', favicon, name='favicon'), ...other-stuff ] In myproject/views.py index = never_cache(TemplateView.as_view(template_name='myproject/index.html')) favicon = never_cache(TemplateView.as_view(template_name='myproject/favicon.ico')) The index works, but favicon doesn't. So what about the other files that need to be served? How can I define those files (anywhere from 4-20 files) to be served by uwsgi? -

Deploying a Django Application (Apache, Passenger, Virtualenv)
Im stuck in deploying my working Django Application on a production PLESK server. The project can be started as a development server successfully by typing: httpdocs# cd mysite httpdocs/mysite# source myvenv/bin/activate httpdocs/mysite# export LD_LIBRARY_PATH="/usr/local/lib" httpdocs/mysite# python manage.py runserver <freyt.de>:8000 Then, if I point the browser to freyt.de:8000 I can see my app. Fine. Right now, I'm trying to call my app by Passenger from Apache. When checking with "passenger-config restart-app" it seems to run, but when curl freyt.de it shows me html with 403 Forbidden. So, I assume my Django app is not started successfully. This is my current folder structure: https://i.stack.imgur.com/8xNMG.png I already adjusted some topics in PLESK as follows: Apache Webserver: wsgi is activated I created a Service Plan and subscribed it with my domain freyt.de In the Service Plan under tab "Webserver" I added additional directives for HTTP as follows.

How to keep Celery running in Django (drf) + Redis + WSGI (EC2)
I don't think its a very new question. I just could not find the right answer. I am trying to use Celery for background tasks while implementing a backend with the Django Rest Framework. I have a Redis server. Celery is working as expected with celery worker -A my_project --loglevel=info However, it does not work if I sop this command. How do I keep that running? I have found a blog with supervisor. I just want to know what is the standard (as well as easier) to do this. -
Formset not applying required=True
I use a formset, made of several forms, where each form contains a ModelChoiceField. However, while I wrote required=True for this field, I am able to post data although I do not select anything in it (when looking at the HTML source code, I can indeed check that required is not included in the select tag). Moreover, formset.is_valid() returns True contrary to what I expected. So far, I have managed to solve this by adding 'required' : 'required' in attrs (see below), but I guess it is not the usual way to achieve this. Here are my forms.py: class InitialForm(forms.Form): group = forms.ModelChoiceField(queryset=Group.objects.all(), required=True, label="Poule", widget=forms.Select(attrs={'class': 'select'})) nb_rounds = forms.IntegerField(min_value=1, max_value=5, required=True, label="Nombre de manches", initial=1, widget=forms.NumberInput(attrs={'class':'input', 'style': 'width:5ch'})) nb_teams = forms.IntegerField(min_value=2, max_value=5, required=True, label="Nombre d'équipes", initial=2, widget=forms.NumberInput(attrs={'class': 'input', 'style': 'width:5ch'})) class FinalForm(forms.Form): def __init__(self, *args, **kwargs): group = kwargs.pop('group') nb_rounds = kwargs.pop('nb_rounds') super(FinalForm, self).__init__(*args, **kwargs) self.fields['teams'] = forms.ModelChoiceField(queryset=Team.objects.filter(group=group), required=True, label="Equipe", widget=forms.Select(attrs={'class': 'select', 'required': 'required'})) for i in range(nb_rounds): self.fields['score_%i' % i] = forms.IntegerField(min_value=0, max_value=50, required=True, label="Score", initial=0, widget=forms.NumberInput(attrs={'class':'input', 'style': 'width:5ch'})) and views.py def initial_new_game(request): # GET request if request.method == 'GET': form = InitialForm() return render(request, 'initial_form.html', {'form': form}) # POST request else: form = InitialForm(request.POST) if form.is_valid(): request.session['group_id'] … -
Django: How do I upload an image to a folder named after the article slug
I defined two models Article, Article_photos. Photos present in each article is stored in the relevant Article_photos model. I intend to store multiple photos per article in this way. I want each photo to be uploaded to a folder by naming the folder in this manner: {slug}_images. This is Article model: class Article(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='Author') article_title = models.TextField() article_content = models.TextField() slug = models.SlugField(max_length=30, blank=True) ... def save(self, *args, **kwargs): self.slug = slugify(self.article_title) super(Article, self).save(*args, **kwargs) And the Article_photos model to store one or more photos: class Article_photo(models.Model): article = models.ForeignKey('Article', on_delete=models.CASCADE) photo = models.ImageField(upload_to='{}_images'.format(article.slug)) Now, when i'm running makemigrations, it's returning this error: AttributeError: 'ForeignKey' object has no attribute 'slug'.
