django.contrib.gis.geos throws SegFault
Following the example code snippet from the django-documentation https://docs.djangoproject.com/en/3.1/ref/contrib/gis/geos/#django.contrib.gis.geos.Polygon, I get a Segfault when iterating over the LinearRing of a Polygon. >>> from django.contrib.gis.geos import Polygon, LinearRing >>> ext_coords = ((0, 0), (0, 1), (1, 1), (1, 0), (0, 0)) >>> int_coords = ((0.4, 0.4), (0.4, 0.6), (0.6, 0.6), (0.6, 0.4), (0.4, 0.4)) >>> poly = Polygon(ext_coords, int_coords) >>> [c for c in poly] [<LinearRing object at 0x7fa81326d610>, <LinearRing object at 0x7fa81326d810>] >>> [c for c in poly[0]] Segmentation fault (core dumped) Why does this code throw a segfault? How can I get the code to run? Originally, I got this error with Python 3.6.7 and Django 3.0.9. I upgraded to Python 3.8.2 in the hope that this is just a compatibility issue between Python 3.6.7 and Django 3.0.9: But upgrading and setting up a new virtualenv did not solve the error. Since the crash happens when iterating over a LinearRing of a Polygon, I tested if looping through just a LinearRing throws an error: >>> from django.contrib.gis.geos import Polygon, LinearRing >>> ext_coords = ((0, 0), (0, 1), (1, 1), (1, 0), (0, 0)) >>> int_coords = ((0.4, 0.4), (0.4, 0.6), (0.6, 0.6), (0.6, 0.4), (0.4, 0.4)) >>> ls1 = … -
Deployment of Django on Heroku Server Error (500) - Static file problem supposedly
I have deployed my django project on Heroku (a very basic project without database). The homepage is working but I have a Server Error (500) when I ask for a page with an imag from my Django project. When I ask a page with an image from internet, it is working fine. So my deduction is that the static files are not properly served but I don't find what it is wrong in my coding.

Is there a specific way of adding apps in Django
I read from a post that Django uses INSTALLED_APPS as a list of all of the places to look for models, management commands, tests, and other utilities. Say I have an app called blog which I would like to add to INSTALLED_APPS, which of these two is advisable: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'blog.apps.BlogConfig', ] OR INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'blog', ] Both method seems to work fine for me as a beginner. -

Stripe keep the current discount of a subscriber
I am currently working on a django project and I integrated stripe to manage monthly subscriptions and renew automatically. Everything is working fine but a problem persists. I have a page to change payment information for a subscriber. For the sake of simplicity, when his card is updated, I recreate a new subscription and delete the old one. If, for example, he has a reduction of 3 months and he has 1 month left, how to take his current reduction voucher and reintegrate it into the new subscription without restarting the period from zero? here is the subscription creation code, when the user registers for the first time, it integrates the promo code ID if there is one. It works very well : obj_sub_created = stripe.Subscription.create(customer=stripe_customer.id,coupon = discount_code,items=[{"plan": offer.stripe_plan_id when a subscriber changes their credit card, I cancel their subscription and recreate a new one. At this moment of the code, I know if there is a current and valid reduction. So I try this: stripe.Subscription.delete(subscription_id) obj_sub_created = stripe.Subscription.create(customer=stripe_customer.id,items=[{"coupon": discount}]) The discount variable is a copy / paste json of what stripe returns to me. But it does not work. Would you have a solution to resume a promotion where … -

How to pass detailView pk to FormMixin in Django?

So I use get_context_data to get current detailView pk and pass it to the form and then inside my form class I used kwargs.pop to get the pk the do some queryset.

Gunicorn --workers 3 --preload
We are running a django web application via Gunicorn + NGNIX (on a linux server). We find that the jobs we are executing via APScheduler are being executed 3 times each (which is undesirable). We solved the problem on our local computers, however, the problem remains when being run via Gunicorn. This was the most informative thread: Make sure only one worker launches the apscheduler event in a pyramid web app running multiple workers Our problem (which would sound simple for someone with more experience than we have) is that we want to execute the following code: env/bin/gunicorn module_containing_app:app -b 0.0.0.0:8080 --workers 3 --preload, we are unsure about two things: We have a domain "example.com", should we adjust the code to be env/bin/gunicorn module_containing_app:app -b example.com --workers 3 --preload or does it not matter? We are trying to find the env/bin/gunicorn folder/path with no luck. We are also trying to understand what to replace module_containing_app:app with. We understand that this could seem like a simple problem, but we have very little experience thus far with gunicorn. Any help would be appreciated as we want to understand. Thank you -

Two 'POST' in Django REST framework, one HTTP 401
I have thwo POST in my Django Rest App: addRestaurant() { this.storeState.pictures = [] let endpoint = `/api/restaurant/`; let method = "POST"; let config = { maps: this.$route.params.maps, adress: this.$route.params.adress, name: this.$route.params.name }; apiService(endpoint, method, config) .then(data => { console.log("Restaurant added!" + data); this.addReview(); }) .catch(err => console.log(err)); }, addReview() { let endpoint = `/api/restaurant_review/`; let method = "POST"; let config = { maps: this.$route.params.maps, review_author: 1 } apiService(endpoint, method, config) .then(res => { this.review_id = res.id; }); }, So after addRestaurant() is done, addReview() is triggered. My issue is that the first API call is successful but I get an error for the second one like "Authentication information were not provided". I've changed my authentication to token authentication and since I've implemented this, I have this issue.

In my site's main page with the listview of all the posts, I am able to get the ajax and the upvote request to work, but only for the top post. No matter if I click on an upvote button from another post, it would only register the effect on the top post. Where did I go wrong? Below is my code. models.py User = settings.AUTH_USER_MODEL #this is the user model class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) #many to one relationship where many posts can be tied to one user content = models.TextField(blank=True, null=True) date_posted = models.DateTimeField(default=timezone.now) image = models.ImageField(upload_to='trade_images', blank=True, null=True) upvotes = models.ManyToManyField(User, blank=True, related_name='upvotes') total_upvotes = models.IntegerField(default='0') def get_absolute_url(self): return reverse('main:post-detail', kwargs={'pk': self.pk}) #returns the url for individual posts def __str__(self): return self.content class Upvote(models.Model): user = models.ForeignKey(User, related_name='upvoted_user', on_delete=models.CASCADE) post = models.ForeignKey(Post, related_name='upvoted_post', on_delete=models.CASCADE) def __str__(self): return str(self.user) + ':' + str(self.post) views.py # list of all posts class post_list_view(ListView): model = Post template_name = 'main/home.html' context_object_name = 'posts' # this is called from the html as 'for post in posts' … -
Django - 404 page handler template cannot load css when settings.DEBUG is set to False
I created a 404 page handler template and I want to add styles to it, but when I try to load the css file when settings.Debug is False, it logs this to the chrome console: Refused to apply style from 'http://localhost:8000/static/errors/404.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. But when settings.Debug is True, it loads the css file without logging any errors 🤔 Setup: If debug is set to true, the errors/404 route will display the 404 page. If debug is set to false, django will use the errors.handlers.handle404 handler to handle 404 errors. I'm telling django to use the handler in this file. I did this because django does not display the 404 page when debug is set to True, it loads the debug page with information on why the error happened Project folder: errors = Name of the app root = Name of the project Working Directory -- root ---- manage.py ---- root --------- __init__.py --------- asgi.py --------- settings.py --------- urls.py --------- wsgi.py ---- errors --------- migrations -------------- __init__.py --------- static -------------- errors ------------------- 404.css --------- templates -------------- errors ------------------- 404.html --------- __init__.py --------- apps.py --------- handlers.py …
