Django query api: complex subquery
I wasted lots of time trying to compose such query. Here my models: class User(Dealer): pass class Post(models.Model): text = models.CharField(max_length=500, default='') date = models.DateTimeField(default=timezone.now) interactions = models.ManyToManyField(User, through='UserPostInteraction', related_name='post_interaction') class UserPostInteraction(models.Model): post = models.ForeignKey(Post, related_name='pppost') user = models.ForeignKey(User, related_name='uuuuser') status = models.SmallIntegerField() DISCARD = -1 VIEWED = 0 LIKED = 1 DISLIKED = 2 And what i need: Subquery is: (UserPostInteractions where status = LIKED) - (UserPostInteractions where status = DISLIKED) of Post(OuterRef('pk')) Query is : Select all posts order by value of subquery. I'm stuck at error Subquery returned multiple rows Elp!!)) -

Django OneToOneField post_save cant call int object
I want to extend my 'User' model with the 'Profile' model. To facilitate this I've created the following model. I wanted to have the linked 'Profile' model be automatically created with each new 'User' model. Based on some comments on stackoverflow / research on the internet (simpleisbetterthancomplex) I came with the following solution: from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver # Create your models here. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile') #Pushup related stats total_pushups = models.IntegerField(default=0) best_consecutive = models.IntegerField(default=0) week_streak = models.IntegerField(default=0) save = models.IntegerField(default=000) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() However, every time I run this (whether through unit tests or 'create superuser' - I have no vies yet, I'm practicing TDD) I get the following error: TypeError: 'int' object is not callable Does anyone here know what I am doing wrong? -

How to include a calendar management module easily within a Django project
I am developing a Python Django platform, using Django, html, and a bit a javascript. This platform aims to manage bookings. I am stuck on a calendar module which I could insert within my html pages. The calendar module would read schedule availabilties and redirect to a booking page when clicked on it. Ideally, I would like something similar to this website : https://www.doctolib.fr/medecin-generaliste/paris (class 'dl-search-result-calendar'). I know it might be coded in AngularJS and Ajax, although my knowledge of this 2 technos is very limited. My question is, what would be the easiest solution to insert such a calendar module, with booking redirect module ? Any help is welcome Thank you -

Call django rest framework CRUD methods from single page angular application
I'm trying to create a single page application that would enable to list, create, update and delete users without refreshing the page. I'm using Django Rest framework and AngularJS which seem to me a good idea for this. I want to use my html template so I created a UserListView class derived from TemplateView and defined the CRUD methods in the view.py by myself like this: class UserListView(TemplateView): template_name = "user_list.html" renderer_classes = [TemplateHTMLRenderer] def list(self, request): queryset = User.objects.all() serializer = UserSerializer(queryset, many=True) return Response(serializer.data) def create(self, request): serializer = UserSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def update(self, request, username=None): user = self.get_object(username) serializer = UserSerializer(user, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def destroy(self, request, username=None): user = self.get_object(username) user.delete() return Response(status=status.HTTP_204_NO_CONTENT) After that I created a template user_list.html like this: {% extends 'general_list.html' %} {% block ng_controller %}userCtrl{% endblock ng_controller %} {% block content %} {% verbatim %} <div class="table-responsive"> <table class="table"> <thead> <tr> <th>Username</th> <th>Password</th> <th>Role</th> <th>Calories per day</th> <th></th> </tr> </thead> <tbody> <tr ng-repeat="user in user_list"> <td>{{ user.username }}</td> <td>{{ user.password }}</td> <td>{{ user.role }}</td> <td>{{ user.calories_per_day }}</td> <td><button ng-click="delete(user)">Delete</button></td> </tr> </tbody> </table> </div> {% endverbatim %} <form ng-controller="userCtrl" … -

How to create a system using Django so that a naive user can edit the content of the Django website without using HTML code?
I have created a personal website for someone using Django (however it wasn't required since website is very simple, but it was their demand!). Now they want that they can edit the content of pages without editing HTML. They now want me to use Django-CMS, I again disagree as I don't think it is required (?) . What should I do to create a system so they can edit the webpage without messing with templates and HTML? The webpages contains few listings, say of 'Books', 'Recent Visits'... etc. I was thinking to create a model for each of them, and let them edit the database using admin, which will then be used by Django to create a dynamic page for their site. Do you think CMS would be a better choice (but then they don't really need me to do anything, they can do it by themselves!) ? I perhaps didn't put my problem properly, but if anyone can understand it, then please give me your suggestions. I can provide more details if anyone wants. -

Python calling methods with variables
I dont know if title is very accurate. I have 5 methods that are webscrapping different websites. Each function looks something like this: def getWebsiteData1(last_article): ty = datetime.today() ty_str = ty.strftime('%d.%m.%Y') url = 'http://www.website.com/news' r = requests.get(url) html = r.text soup = BeautifulSoup(html, 'html.parser') articles = soup.findAll("div", {"class": "text"})[:15] data = list() for article in articles: article_data = dict() if article.find("a").get('href') == last_article: return data else: article_data["link"] = article.find("a").get('href') article_data["title"] = article.find("a").get_text() data.append(article_data) return data So each function returns data that is a list of dictionaries. I have another method that calls this method. def CreateArticle(website_number, slug): website = Website.objects.get(slug=slug) last_article = website.last_article data = getWebsiteData1(last_article) //here i want to do something like data = website_number(last_article) but ofcourse this doesnt work if len(data) == 0: return "No news" else: for i in data: article = Article(service=service) article.title = i['title'] article.url = i['link'] article.code = i['link'] article.save() service.last_article = data[0]['link'] service.save(update_fields=['last_article']) return data[0]['link'] I want to be able to call CreateArticle(website_number) and tell this method which getWebsiteData method it should call, so i can have only one CreateArticle method and not for each webscrapper method another CreateArticle method. I hope my question is clear :D -
Is it possible to limit a StreamField to accept exactly two blocks?
The title says it all, I haven't been able to find any other information online. I'm wondering if it is possible for me to get secondary_links = StreamField([ ('Page', SerialisedPageChooserBlock())]) to accept exactly two blocks. -
Django Materialize.css Navbar
I'm working on a Django webapp and I'm using Materialize for CSS I have placed the Materialize file in the static folder in the app. I have issues with the Navbar that it works fine when in full-screen but when I resize the browser the hamburger icon for mobile navbar doesn't work. When clicked on it, it just goes to the /# page and doesn't openup from the side as it should. Do I have to make any change in the Django or Javscript files files? How can I fix this issue?
