Map integration not wokring
The following are the two lines I put in the head tag of my html <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&key=AIzaSyC_Ii8L8wy40S8pB-eUBg13MlIOGYHXx6Y"></script> <script src="{% static "js/mapscript.js" crossorigin="anonymous" %}"></script> The below is the script I use to load map into my html. In my html I have a div tag with ID equal to map_canvas. var map; function initialize() { console.log("Loading map"); var mapOptions = { zoom: 12, center: new google.maps.LatLng(55.85361568022353, -4.288761402220929) }; map = new google.maps.Map(document.getElementById('map_canvas'),mapOptions); } google.maps.event.addDomListener(window, 'load', initialize); The issue is that even if I added a API key and have a billing registered for google maps, map is not rendering after using the code above though this javascript code is hit. Can anybody give suggestions? -

ModuleNotFoundError: No module named 'pip._vendor.six'
I am doing some example from the book called Django for professionals. I am at the part where you have to run the django server with docker-compose command. However, I got an error like this: raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) I realised that I needed to download psycopg2 with pip3 but then I got this error: from pip._vendor.six import iteritems ModuleNotFoundError: No module named 'pip._vendor.six' I don't understand why I received this error since I followed every step on the book carefully. I am using virtualenv as well so i decided to open a new terminal and downloaded it there. Download was a success however when I download it in virtual environment I get an error. What do you guys think is the problem and how can I solve it? -

Django: It takes time for order_by() and count()
The following model object has about 300k rows in postgres, and I have set db_index=True for the published_at field. For some reason, order_by() takes a long time. (+100ms or so) Also, .count() takes a long time. (about 150ms). Why do these take so long even though the index is specified? class Video(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.CharField(max_length=300) thumbnail_url = models.URLField(max_length=1000) preview_url = models.URLField(max_length=1000, blank=True, null=True) embed_url = models.URLField(max_length=1000) embed_source = models.ForeignKey(EmbedSource, on_delete=models.CASCADE) duration = models.CharField(max_length=8) tags = models.ManyToManyField(Tag, blank=True, db_index=True) views = models.PositiveIntegerField(default=0, db_index=True) is_public = models.BooleanField(default=True) published_at = models.DateTimeField(default=timezone.now, db_index=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: ordering = ["-published_at"] def __str__(self): return self.title -
How to change the starting auto-generated-primary key id in a Django + PostgreSQL web application?
I have a web application build on Django using PostgreSQL database. In a few tables, I have auto-generated-IDs being used as primary keys. Due to some unexpected circumstances, I had to uninstall everything on the Linux server and again setup them on a different Linux server. I want to use all the data which I had stored earlier and taken dumps in csv files for each table before uninstalling. So, I've used copy function and and copied all columns data (including "id") into the new database. Now, when using the Django app which is trying to insert data into the tables, its throwing PRIMARY KEY ERROR saying that id already exists. So, what can I do now so that this Django+PSQL app uses id from some 1000 or 5000 rather than from 1 since the previous ones are already used? How to know this setup not to use 1 to 1000 as its already used. I don't think any screenshots are required for this. Kindly let me know if I have to make myself more clear. Thanks much in advance. -

Is @transaction.atomic cheap?
This is mostly curiosity, but is the DB penalty for wrapping an entire view with @transaction.atomic a negligible one? I'm thinking of views where the GET of a form or its re-display after a validation fail involves processing querysets. (ModelChoiceFields, for example, or fetching an object that the template displays.) It seems to me to be far more natural to use with transaction.atomic() around the block of code which actually alters a bunch of related DB objects only after the user's inputs have validated. Am I missing something? -
Is Django blocking requests.post data in production platform?

Docker-compose (and django): Can't get environment variables onto the services
I'm trying to write a small docker(-compose) deployment solution for a small Django application. Currently, the django-compose file, named docker-compose.dev.yaml looks something like this: version: "3" services: backend: build: context: ./backend dockerfile: Dockerfile command: python manage.py runserver 0.0.0.0:8000 ports: - 8000:8000 env_file: - dev.env The file dev.env looks like this: DEBUG=1 SECRET_KEY=We9ZyuSKsP9Mgvsrt74gExF8baWbGL # not important that this leaks DJANGO_ALLOWED_HOSTS=localhost However, when django tries to start, I get the following: #11 0.634 ALLOWED_HOSTS = os.environ.get("DJANGO_ALLOWED_HOSTS").split(" ") #11 0.634 AttributeError: 'NoneType' object has no attribute 'split' Basically, the environment variable is returning None, meaning the variables aren't getting onto the container. I tried, according to the docs, to do this: # ... environment: - DEBUG - SECRET_KEY - DJANGO_ALLOWED_HOSTS Without any luck. Any ideas? The repository behind the code is public, I invite you to try.

Apache server with django is saying: Access denied for user 'root'@'localhost'
I am trying to run a working Django server on Apache2.

This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host.

How to render choices in a Django field based on a condition

Update profile picture through clicking on picture itself Django
I'm trying to find some info online on how to update my user's profile picture on the profile page in the same way that social media applications do it, i.e. by clicking on the profile picture itself and getting asked for the file upload straight away. However, all I'm finding online is options to create a form to do that job, but then it's going to be an upload button that does the job, which is not the same. How do I get the image to be clickable, opening a file upload after I click it that would then update my model ImageField? -
Understanding flaky Django tests: Creation order affecting array order
I have a test in Django that looks something like this: class WebhookClientSerializerTestCase(TestCase): def test_serializes_agent_from_client(self): agent1 = factories.AgentUserFactory(email='dave@agently.com') agent2 = factories.AgentUserFactory(email='jim@agently.com') client = factories.ClientFactory(agents=[agent1, agent2]) schema = serializers.WebhookClientSerializer() # do some stuff data = schema.dump(client).data self.assertEqual(data['agents'][0]['email'], 'dave@agently.com') self.assertEqual(data['agents'][1]['email'], 'jim@agently.com') We create a entity called an Agent, then another, and run through some custom serializer logic. The serializer returns an array of serialized agent data. There are other tests defined within the same class. However, sometimes the agents come out in the wrong order. It fails with AssertionError: u'jim@agently.com' != 'dave@agently.com' I had assumed that when the entities were created, that it would be done sequentially. This test runs fine locally, but it fails in CI/CD sometimes, not always. We use the --parallel flag when running tests, but I don't see where or how the asynchronicity is messing with the order of the output array. Why does the order change, and how could I write this test more robustly? -
save() method for django_comments_xtd model
I am using Wagtail + Django_comments_xtd + Django. My_Django_App/models.py from wagtail.core.models import Page class PostPage(Page): ... from django_comments_xtd.models import XtdComment class PostComment(XtdComment): page = ParentalKey('PostPage', on_delete=models.CASCADE, related_name='rn_comments') def save(self, *args, **kwargs): if self.user: self.user_name = self.user.username self.page = PostDetail.objects.get(pk=self.object_pk) super(PostComment, self).save(*args, **kwargs) On Wagtail CMS, if I revise an existing post which has some comments already and publish the revised post again, I thought PostComment.save() should not be triggered any more. However, during my debug, I found it was triggered unexpectedly. I guess that I need to fine-tune PostComment.save() to achieve above intention. After some researches on StackOverflow, Identifying new Model Instance in Django Save with UUID pk In a django model custom save() method, how should you identify a new object? I realize that I might need to use PostComment._state.adding and force_insert within the save() to achieve my intention. Can anyone show me how should I fine-tune PostComment.save() ? -
django-filter: How to get the choices from related model?

Django caches user object
Our websites sometimes has around 600 authenticated users trying to register for an event in a timeframe of 5 min. We have a VPS with 1 CPU and 1GB ram. On these moments the site slows down and gives a 502 error. For that reason I'm using per-site cache with FileBasedCache. This works excellent and stress tests work fine. But, when people login, they're redirect to their profile. This is the code: class UserRedirectView(LoginRequiredMixin, RedirectView): permanent = False def get_redirect_url(self): return reverse("users:detail", kwargs={"membership_number": self.request.user.membership_number}) the user is redirect to an url with their membership_number class UserDetailView(LoginRequiredMixin, DetailView): model = User slug_field = "membership_number" slug_url_kwarg = "membership_number" Some users are reporting that they are redirected to someone else his/her profile after logging in. How does this work? How to prevent user specific parts of the website to be cached? e.g. users also see a list of events that are specific to the groups they are in. In other words, every user should see a different list. Any ideas? Best practices?
