bootstrap padding from sidebar
I am creating a site from scratch using Django and bootstrap. I've created a sidebar as a Django template and used {% include 'website/components/sidebar.html' %} to include it on all pages. but for each new page, the padding between the sidebar and any other content is not aligned. How do add a margin all the way around so that any content is central to the space between the sidebar and the edge of the screen? The sidebar is using some custom CSS and the rest of the site is using bootstrap. I've wrapped the content of the next page in container-fluid but I'm not sure about the approach. -

Increment Integer Field in Django
I am creating a simple blogging application and would like users to be able to like a post. In terms of scalability I've decided it would be best to have likes as a separate table made up of pointers to both the user and post. I have managed to enable the post request adding a like to the model however the likes field in the post model is not incrementing. I've tried using a simple likes += 1 technique in the serializer but that made no changes and have now used an F string but still no changes are being made. I am still fairly new to Django and suspect it may be because I'm trying to update a field on a different model within a CreateAPIView serializer but I'm not sure. This is what I have so far # views.py class LikeView(generics.CreateAPIView): permission_classes = [ permissions.IsAuthenticated, ] queryset = Like.objects.all() serializer_class = LikeSerializer def like(self, request, format=None): serializer = self.serializer_class(data=request.data) if(serializer.is_valid()): user_id = serializer.data.get('user_id') post_id = serializer.data.get('post_id') l = Like(user_id=user_id, post_id=post_id) l.save() # likes field not updating with this post = Post.objects.get(id=post_id) post.likes = F('likes') + 1 post.save() return Response(LikeSerializer(l).data, status=status.HTTP_200_OK) return Response(serializer.errors(), status=status.HTTP_400_BAD_REQUEST) #models.py class Post(models.Model): id = … -

Checkbox ALWAYS returns False/ not in request.POST - Django

Why Django doesn't see change when I add/remove a field from my models? [closed]
I removed a ForeignKey from a model and I guess the migration wasn't applied properly. It was three days ago and others migrations were applied since then. The problem is that now I'm unable to recreate the same ForeignKey because Django doesn't see the change in models.py when I comment or uncomment the field. I assume it thinks the migration is already applied but it's not because my code complains the relation doesn't exist. What is the best way to solve this issue ? class Account(TimestampedModel): name = models.CharField(max_length=50, null=True) # exchange = models.ForeignKey(Exchange, on_delete=models.CASCADE, related_name='account', null=True) # ForeignKey I cant recreate I have tried to specify the name of the application when calling makemigrations but it doesn't help. -
Deploy Django Project Using Pyinstaller
I have a django project, that works similar to Jupyter Notebook, in terms of Being a program launched offline in localhost on a web browser, moreover my webapp has an opencv webcam pop-up, that will be launched when you press a button. I want to deploy my django project, so it can be launched by just clicking a file in Windows. According to what I read, There are two possible solutions: Install Python Interpreter with Dependencies on client computer first, and using a bat file, to launch the django server. Containerizing the Django project with Python and its dependencies, either using Docker or perhaps an exe file? Which solution is better? I would prefer the second one personally, but I’m confused how to do so. Can it be done as simple as using pyinstaller or not? Here are my dependencies for reference: Django pillow django-object-actions django_user_agents django-cleanup opencv-python imutils cmake dlib face-recognition -

Best way to deploy multiple client websites by Wagtail
I want to create wagtail website for my clients. The webistes will be identical and have same features, but the templates should be different. Every time I upate a feature to a new version, all websites will get the latest version automatically. By this approach, I don't need to deploy new feature versions (or base website version) to my clients separtely. I just need to deploy onec & all clients will get the latest website version. I will use 'Multi-instance' feature of Wagtail which seems to fit to my requirement. https://docs.wagtail.org/en/stable/advanced_topics/multi_site_multi_instance_multi_tenancy.html On this page, they mention 'Multi-instance' feature of Wagtail. Quote: "multiple sites share the same, single set of project files. Deployment would update the single set of project files and reload each instance." https://www.accordbox.com/blog/add-bootstrap-theme-wagtail/ Say, I want to have 2 different blog templates in this tutorial. The blog temlate file is 'post_page.html', and is a project file, so it will be deployed once and all website will get the same template, in the 'Multi-instance' feature of Wagtail. So my question is: How can I deploy one blog template (post_page.html) to one client website, & another blog template to another client website? -

Purpose of using an API
I'm learning API. So, I have a Django app, in development (I'm building it).I can also render my data (or user's data POST through forms) with urls.py, views.py and my template files.

How can I do this complex Django queryset correctly?
Let's say I have these three models: class Author(models.Model): name = models.CharField(max_length=64) class Book(models.Model): author = models.ForeignKey( Author, blank=True, null=True, on_delete=models.SET_NULL ) name = models.CharField(max_length=64) class Store(models.Model): books = models.ManyToManyField(Book) name = models.CharField(max_length=64) I don't know the author of some books. In these cases, the author is null. When I query Store, I would like to know how many books each store has and sort them. So my queryset is something like this: Store.objects.all().annotate(books_count=Count('books')).order_by('-books_count') Now, what if I want to count only the books that have an author? I tried this queryset, but it is clearly not correct: filter = Q(books__author__isnull=False) Store.objects.annotate(books_count=Count(filter)).all().order_by('-books_count') Does anyone know the correct way to do this query? -
