Django ManyToMany Creating Duplicate Relationship for Self Referential Attribute
I've got a model that looks something like this: class Session(models.Model): sub_sessions = models.ManyToManyField("self") Now when I do something like: session_1 = Session.objecte.get(id=1) session_2 = Session.objects.get(id=2) session_1.sub_sessions.add(session_2) What happens is that a relationship is created such that session_2 is in session_1's sub_sessions field, but session_1 is also in session_2's sub_sessions field. I imagine this makes sense at some level being a ManyToManyField relationship, but it's really not what I want. I only want session_2 to be in session_1's sub_sessions field, but not the other way around. I suppose I can instead create a ForeignKey relationship, but it'll just break a few of my current coding implementations and I'd really love to have some sort of a way to make this work. Thanks! -

How to combine two views in django?
I want to insert another view into a view. Basically I'm using Django filter package and value output directly populates template without my need to writing any view class. I want to insert another html into the current template. Something like this: {% include 'countsnippet' %}, but this gives me error template doesn't exists. Alternatively I've tried using {% include 'countsnippet.html' %} but this doesn't calls the views and fields remains empty. What approach I can use to include another view? This is my countsnippet html. {% block content %} <p> INFT : {{ inft }} </p> {% endblock %} I've already made view for countsnippet and its url looks like this: url(r'countsnippet/$', countsnippet, name='countsnippet') I've though about quite a number of times and I feel It would be really interesting to find out how to combine multiple pages into one and make something complex. Although I wasn't ever able to figure out any solution for that. -

Getting a count per hour for the past week
I have a model of Photos taken. I am building a heatmap with Javascript of when photos were taken of the last7 days. I am showing it per hour. My Photo Model has a timestamp DateTime field. How would I make a list like this showing total photos per hour per day for the past week? The javascript expects an array like this: const heatmapDataSource = [ [0, 0, 3], [6, 23, 3], .... ]; heatmapDataSource[0][0] is the day of the week (Today (Tuesday) 0, last week Wednesday (6) - Today is always 0 heatmapDataSource[0][1] is hour (0 == 24:00 and 23 == 23:00 etc) heatmapDataSource[0][2] is the count value for that hour Hope this makes sense! -
Django view: get the count of rows in all tables in a MySQL database
I can get the count of rows in all tables in a MySQL database with this sql query: SELECT SUM(TABLE_ROWS) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '<database>'; Is there a way to get the same with the model query API in a django view? One way would probably be using the raw() manager method, but I wonder if there is a more elegant solution. -

Django QuerySet Limit hits database too many times?
I've recently stumbled upon a massive bottleneck on a production website only after updating from Django 1.11 > 2.1 Here is my simple slice of code; pages = Page.objects.filter(cat="news_item").order_by('-created')[:2] This in turn, creates around ~30 queries, around the number of pages under that specific filter. I have now implemented a somewhat hacky way to resolve the 32 queries which i'm not satisfied with. pages = [Page.objects.filter(cat='news_item').order_by('-created')[i] for i in range(0,2)] Speed is notably effected, a few other chunks of code used this method which caused >400 queries per page load - I have since adapted these to use a combination of the above code & Model.objects.raw Did something change in Django 2.0/2.1 that I missed or does the [:2] limit not work correctly? -

Django ecommerce: Adding Products with one to many relationship to Services into a Cart
I am trying to allow customers the chance to add products & services to a cart at the same time. Customers will add Products and then add a few Services related to each Product before checking out. It will be better if customers could add a few products in the cart at the same time. For example, a customer purchases flight tickets (Product) for a few routes and adds to that flight ticket a few other Services related to each route such as meal types, baggage allowance, etc. My question would be is it possible to use the following views.py code: views.py from cart.cart import Cart from shop.models import Product def add_to_cart(request, product_id, quantity): product = Product.objects.get(id=product_id) cart = Cart(request) cart.add(product, product.unit_price, quantity) def remove_from_cart(request, product_id): product = Product.objects.get(id=product_id) cart = Cart(request) cart.remove(product) def get_cart(request): return render_to_response('cart.html', dict(cart=Cart(request))) and modify it to work something like this: from cart.cart import Cart from shop.models import Product, Service def add_to_cart(request, product_id, quantity, service_id): product = Product.objects.get(id=product_id) service = Service.objects.get(id=service_id) cart = Cart(request) cart.add(product, product.unit_price, quantity, service, service.unit_price) I am a beginner and am unsure how to go about solving this problem of adding products with one to many relationship to services to a … -

I am trying to register users with UserCreationForm fields ( username , password, password ) and I would like additional input fields on the register form such as location and gender. With the below code, on the register page its giving me a select id drop down of all user and location and gender input fields. Is there any way I can get all the fields on the same page.( username , password, password2 , location, gender ) models..py class UserProfile(models.Model): user = models.OneToOneField(User, related_name='profile', on_delete=models.CASCADE) location = models.CharField(max_length=140) gender = models.CharField(max_length=140) def __str__(self): return 'Profile of user: {}'.format(self.user.username) view.py class register_user(CreateView): model = UserProfile template_name = 'Mel/register.html' success_url = 'list' fields = '__all__'
