In Heroku don't display map when edit/update polys Heroku. But when I backup the database in docker the map is displayed without trouble Docker.

What are steps necessary to deploy django application to make it live using apache server?
I am host my locally build django app into live server in Digital Ocean using public IP. My VM is debian based. What i did is: Copy my "attendance" project into /var/www/. I created new conf file in: /etc/apache2/sites-available/attendance.conf. I enable it and disable 000-default.conf. In attendance.conf I put code like: <VirtualHost *:80> ServerAdmin admin@143.244.134.97 ServerName 143.244.134.97 ServerAlias 143.244.134.97 DocumentRoot /var/www/attendance ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined I enable apache 2 also. When I go to the browser I view only the files. It is like: [image seen in browser][1] Do I didn't edit properly for wsgi setup in apache2>(application.conf). OR What are the other possible solution to make my site live? -

Django "extra_context" not being passed to form renderer when using FormView
Django version 4.1 When I pass "extra_context" to my class-based view, it seems to get filtered out before being passed to the form renderer.

Poetry install doesn't seem to install the packages in the right place
So I'm having a problem for quite some time which I cannot get solved. Basically I took over a project which uses Poetry for package managing (It is a Django project). Adding packages with 'poetry add' and then installing them via 'poetry install' all works fine locally (I use a Docker container). But when pushing the changes to my server and then running 'poetry install' it says the packages are already installed. But when running the Django application, I get an internal server error saying the package doesn't exist. An example is given with the 'openpyxl' package. pyproject.toml ...

Django foreign key query returns records that are not in the database
I have a strange situation where Django seems to be giving me records that do not actually exist in the database when queried via a related_name on a foreign key. Here's a simplified example: Let's say I have a Person model and a Pet model, where each Pet has an owner, which is a foreign key on Person: class Pet(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name =models.CharField(max_length=50, null=False, db_index=True) owner = models.ForeignKey("Person", null=False, related_name="pets", on_delete=models.CASCADE) relationship = models.IntegerField(null=False, choices=PetRelationship.choices(), db_index=True) Now, I have the below function that retrieves a person's pets: def pet_tester(person): for pet in person.pets.filter(relationship=PetRelationship.FRIENDLY): pet_id = pet.id LOGGER.info(f"*************** pet.id = {pet_id}") LOGGER.info(f"******* Pet exists? = {Pet.objects.filter(id=pet_id).exists()}") ... Note that this is NOT a "minimal reproducible example". I can only reproduce it in my much larger application. For some reason (in the real app), the "exists" query is coming back as False. The output is like this: *************** pet.id = 123e4567-e89b-12d3-a456-426614174000 ******* Pet exists? = False If I query the actual database (Postgresql) directly (outside of Django), that pet ID sure enough does NOT exist. However, the person.pets.filter query is returning it just the same. I do not understand how this is even possible. It JUST retrieved the … -

Django template not displaying data from database
I am running into an issue where my database is information is displaying on one template, but I want certain parts to display on another page for a blog. When I click into physics-blog it will display my images and post title. For this, I have looped through the database. Works fine and perfectly. But when I click into one of them and want to show {{ physicsBlog.body }} it doesn't show anything. Which I can't wrap my head around because that works just fine in the other ListView template, but not in the DetailView template. Here is my code. models.py class physicsBlog(models.Model):title = models.CharField(max_length=250)blog_image = models.ImageField(null=True, blank=True)description = models.CharField(max_length=200)author = models.ForeignKey(User, on_delete=models.CASCADE)body = RichTextField(blank=True, null=True)date_created = models.DateField(auto_now_add=True)def __str__(self):return self.title + ' | ' + str(self.author) views.py class physicsBlogListView(ListView):model = physicsBlogtemplate_name = 'physics.html'ordering = ['-id']class physicsBlogDetailView(DetailView):model = physicsBlogtemplate_name = 'physics-blog-details.html' urls.py urlpatterns = [path('', views.home, name="home"),path('physics-blog', physicsBlogListView.as_view(), name="physics-blog"),path('physics-blog/<int:pk>', physicsBlogDetailView.as_view(), name="physics-blog-details"),path('crypto-blog', cryptoBlogListView.as_view(), name="crypto-blog"),path('crypto-blog/<int:pk>', cryptoBlogDetailView.as_view(), name="crypto-blog-details"),] -
