Calculate Business Days in Django Annotate
I wanted to calculate business days in Django annotate. For example, if an event was generated 7 days back, and I wanted to know how many business days had passed. As per the example, 7 days includes [Monday - Sunday], and I only wanted to include [Monday - Friday], which means 5 business days. I've done this logic via some pythonic hack, but I wanted to do this in Django annotate() method. So I can filter the results based on business days. Here is an example of what I've done so far: table_values = Table.objects.all().annotate(issue_severity=datetime.utcnow() - Max("event__created")) for table in table_values: date = datetime.now(timezone.utc) - table.issue_severity dates = (date + timedelta(x + 1) for x in range(table.issue_severity.days)) table.business_days = sum(day.weekday() < 5 for day in dates) -
Where should validation logic go in this DJANGO project
I have an existing python program which verifies coordinates are correct - by that I mean they are in the correct place, not a simple range check. In my Django project I want someone to be able to send these coordinates in, and use my existing code to verify they are correct before saving them to the model. My question is, where does this logic go? Do I put it in the view and reject the HTTP request, if the coordinates are invalid? - this seems simplest to me? Or does this go in the model somewhere, and I prevent invalid coordinates from being saved to the database? I'm new to Django, so not sure what is a good practice / idea. An issue I see with writing a custom validator(?) is these coordinates come in pairs. -
Django pass url context via function
I have a urlpattern in the urls.py file defined as path('profile/<str:uname>/', views.UserProfile, name='UserProfile'), I need to do the following at the return of my function in my views.py file, return render(request, 'UserProfile') How do I pass the 'uname' parameter in this return correctly? P.S. I don't know if this is even possible. -
Prevent people from seeing other user profile pictures
I created a field to allow a user to upload a profile picture. In the template I check if the user is logged in and there is a profile image, otherwise I display a generic one. How can you prevent someone from guessing other filenames to see another users profile picture? {% if user.is_authenticated and user.profile.image %} <span class="avatar avatar-sm" style="background-image: url({{ user.profile.image.url }})"></span> {% else %} <span class="avatar avatar-sm" style="background-image: url('/media/profile_pics/default.png)')"></span> {% endif %} -
Django - Programatically access property of model class (getattr throws Attribute Error)
I am overriding a Model's save method so I can log changes made to certain fields: class Model(models.Model): name = ... price = ... ... __original_name = None __original_price = None def save(self, force_insert=False, force_update=False, *args, **kwargs): for field in [ 'name', 'price', ]: print(self.__original_name) # works original_value = getattr(self, f"__original_{field}") # throws Attribute Error # other logic ... self.__original_name = self.name self.__original_price = self.price super(Model, self).save(force_insert, force_update, *args, **kwargs) Error thrown: AttributeError: 'Model' object has no attribute '__original_name' The method works correctly if I don't loop over the fields and access each field independently with self.__original_field, but I am trying to refactor the code so I can easily start tracking other fields as needed. Is there a different built in method I can use to access the value programatically? (cant use self[f"__original_{field}"] cause it is not subscriptable) -

What is the best way to develop an Elastic Beanstalk Django application locally?
I have recently deployed my Django application on Elastic Beanstalk. I have everything working now, but I'm curious what the best way to develop locally is. Currently, after I make a change locally, I have to commit the changes via git and then run eb deploy. This process takes 1-3 minutes which is not ideal for making changes. The Django application will not run on my local machine, as it is configured for EB. -
Prevent Django health check endpoint logs from being sent to Sentry
I have a Django application with a health check endpoint that's using this repo. In the url_patterns I have added the following line: url(r'^ht/', include('health_check.urls')), The issue is that the health check is filling all the Sentry transaction limits. How can I exclude the health check endpoint in Sentry? -
How to save stripe webhook data to session variables in Django?
I am currently working on a 'success' page for my Django project (which uses Stripe to take payments). I would like to show their order total, with tax, on this page. My Stripe webhook is running and posting data, but for the life of me I can't use this data outside of the webhook's veiw. Normally, when I want to inform one view with data from another, I take advantage of Django's session variables. When I save the session variable, however, attempting to use it in my SuccessView returns 'None' rather than the value saved to it. Any help would be appreciated. Here is my relavent code: views.py def stripe_webhook(request): payload = request.body sig_header = request.META['HTTP_STRIPE_SIGNATURE'] event = None try: event = stripe.Webhook.construct_event( payload, sig_header, settings.STRIPE_WEBHOOK_SECRET ) except ValueError as e: # Invalid payload return HttpResponse(status=400) except stripe.error.SignatureVerificationError as e: # Invalid signature return HttpResponse(status=400) # Handle the checkout.session.completed event if event['type'] == 'checkout.session.completed': session = event['data']['object'] customer_email = session["customer_details"]["email"] line_items = stripe.checkout.Session.list_line_items(session["id"]) print(line_items) stripe_price_id = line_items["data"][0]["price"]["id"] price = Price.objects.get(stripe_price_id=stripe_price_id) total_paid_cents = line_items["data"][0]["amount_total"] total_paid_dollars = total_paid_cents / 100 request.session['total_paid'] = total_paid_dollars return HttpResponse(status=200) class SuccessView(TemplateView): template_name = "musicstudios/success.html" extra_context = sidebar_context def get_context_data(self, **kwargs): context = super(SuccessView, self).get_context_data(**kwargs) order_id = … -

Self-hosting multiple sites via one Django project + apache - Django Sites framework
I have a self-hosted (raspberry pi) website running on Django - one project with several apps all serving on one domain name. I'm more of a programmer than a server admin, but it works! Now, I'd like to break one of those apps out onto a second domain name, but still hosting from my pi. --I've looked into a lot of tutorials on how to do this as well as checked out answers like this one but the server-related instructions on everything I've found so far all go a bit over my head or don't seem to match up with my setup. --I've tried the Django Sites framework and I've also followed this tutorial. While I was able to get my site objects in the db, all requests seem just to go to SITE_ID=1, regardless of domain name. I've seen conflicting information here about whether or not SITE_ID should be present in settings.py, but whenever I remove it, I just get errors about it (even though I do have the CurrentSiteMiddleware installed as well as a custom middleware like indicated in that tutorial).

SecretManagerServiceClient raises 403 Permission denied CONSUMER_INVALID in Google App Engine but `gcloud secrets versions access` works

jango.db.utils.ProgrammingError: relation <relation_name> already exists
I am starting a project that is based on some already existing relational data. One problem is the data is not in the exact form I would want it. For example boolean fields are integers etc. What I though would be a good idea to start my project is the following: Download the data in the form they're provided (.csv). Create a database from the csv data, using pandas' dataframe.to_sql method. Create the django app and load the models from the database into models.py using manage.py inspectdb. Change all fields to whatever I want and remove the managed = False in each class Meta subclass of my models class. That's it. Now my project would turn to a normal project like all others. It would keep the data from the tables, but it would allow me to alter the schema however I want (*). The fact that I used dataframe.to_sql method made the data's form even more problematic, for example there are not foreign keys but just varchars or integers. So I had to turn this fields to ForeignKeys manually. The issue I am facing is that whenever I try to apply the migrations I get this error: django.db.utils.ProgrammingError: relation … -

How to properly config a django application on cpanel
Before now, the main domain was serving a WordPress website but I needed to replace that with a new django application. I was able to successfully deploy the Django application to cPanel, and the application was served on a subdomain without any problems. But when I edit the application url to point to the main domain, the homepage renders without the static files. Initially, I thought it was a static file issue until I tried to access other pages, but all I keep getting is a 404 page that is being served by the old WordPress. Somehow the old wordpress website is conflicting with the django app. I'm not sure why the old wordpress is still trying to serve the new django pages except the homepage, even though static files are also missing on the homepage.
