Django - adding gamification features
I have a medium size Django REST app that I'm looking to add gamification features to. The application in question is a school webapp where students can create mockup quizzes, participate in exams that teachers publish, and write didactical content that gets voted by other students and teachers. I want to add some gamification features to make the app more interesting and to incentivize participation and usage of the various features: for example, each student will have a personal "reputation" score, and gain points upon completing certain actions--a student may gain points when completing a quiz with a high score, when submitting some content, or when receiving upvotes to such content. The tricky part is I want to be able to have this logic be as separate as possible from the existing codebase, for various reasons: separation of concerns, ability to plug the engine in/out if needed, ability to easily deactivate features for certain groups of users, etc. What I'm looking for here is some software engineering advice that's also Django-specific. Here's a high level description of what I'm thinking of doing--I'd like some advice on the approach. create a new gamification app. Here I will have models that describe … -

Django NoReverseMatch after deleting object
Im hard stuck here, everything is connected via pk, and on group of accounts can see only their data whiel an other group can see all data from the other group. But I have a model where ONLY the staff group can add update and delete while the other group can only update. While it works fine and all when the staff group deletes all 'teachers' in that case I get no reverse match error. The thing is, In the view the staff needs to see everything compact in their template like the school and teacher and so on. right now I either have atleast two type of teacher and the template works or the school is sorted normaly while the teachers are all shown under every school template hope you get what I mean. I only need something that dont break if a FK is deleted so that if staff makes a new teacher everything works template <ul> <li>{{Ansicht.Lehrer_FK.Leitung_der_Klasse}}</li> <a href="{% url 'LehrerAktualisierenVerwaltung' Ansicht.Lehrer_FK.pk %}" >Lehrer Aktualisieren</a> <a href="{% url 'LehrerEntfernenVerwaltung' Ansicht.Lehrer_FK.pk %}" >Lehrer L&ouml;schen</a> </ul> form class LehrerAktualisierenVerwaltung(LoginRequiredMixin, UpdateView): model = LehrerTabelle fields = '__all__' template_name = 'SCHUK/LehrerAktualisierenVerwaltung.html' context_object_name = 'LehrerAktualisierenVerwaltung' def get_success_url(self): return reverse('Dashboard') url path('LehrerAktualisierenVerwaltung/<int:pk>/', LehrerAktualisierenVerwaltung.as_view(success_url="Dashboard"), … -
How to build Django external URLs with differing protocols
I am soliciting and parsing user content for all types of URLs (starting with http|https|ftp as well as only www.xxx.xxx), e.g. http://www.foo.bar and www.google.com and https://guardian.co.uk. At a later stage I am presenting these URLs back in a template and want to create links that go straight to those destinations: <a href="//{{resource.text}}" target="_blank" role="button">{{resource.text}}</a> However, if I don't prefix with // I get relative URLs (which obviously isn't working), but if I do add the prefix and create absolute URLs, I'm up the creek as the protocols differ between the various URLs. Is there a way to tell Django to treat the URLs naively and let the browser sort out the context? -

Django: How can I use inlineformset to save multiple forms that all share the same FK as another object being created on the same form page?
I have two models Animal and Gene_Animal_Bridge. I have a form page that allows a user to add a new animal to the database and attach any genes that they have. The genes are stored in Gene_Animal_Bridge which contains the FK of the animal it belongs to, and the FK of the Gene that is stored in the GeneInfo Model. Everything works fine but when it comes to iterating over the formset, only 1 gene will be saved and any other gene forms added on the page won't save.

Django: Get count of specific values by month in queryset
my model is like so: class Project(models.Model): name = models.CharField(max_length=1000, null=True, blank=True) date_created = models.DateTimeField(auto_now=True) status = models.CharField(max_length=1000, null=True, blank=True) The status field has about 5 different options (won, lost, open, pending, cancelled). I need to know how to get the number of projects with x status in each month in a given time range query. I was able to get the sum total of projects each month with the following annotation: Project.objects.all().annotate(month=TruncMonth('date_created')).values( 'month').annotate(total=Count('pk'), ).order_by('date_created') However, I am looking for an output like this: [{date: 'January 2020', total: 30, won: 10, lost:10, open: 10, pending: 0, cancelled: 0}, {date: 'February 2020', total: 30, won: 10, lost:10, open: 10, pending: 0, cancelled: 0}, {date: 'March 2020', total: 30, won: 10, lost:10, open: 10, pending: 0, cancelled: 0}] Ideally I would like the keys within the final output to be dynamic (i.e. if a new status is added, we won't need to hardcode a new key into the query) but I don't know if this is possible or not.

Django CheckConstraint not enforcing check on model field
I am using Django 3.2. Backend database used for testing: sqlite3 I have a model Foo: class Foo(models.Model): # some fields ... some_count = models.IntegerField() class Meta: models.constraints = [ models.CheckConstraint( check = ~models.Q(some_count=0), name = 'check_some_count', ), ] I also have a unit test like this: def test_Foo_some_count_field_zero_value(self): # Wrap up the db error in a transaction, so it doesn't get percolated up the stack with transaction.atomic(): with self.assertRaises(IntegrityError) as context: baker.make(Foo, some_count=0) When my unit tests are run, it fails at the test above, with the error message: baker.make(Foo, some_count=0) AssertionError: IntegrityError not raised I then changed the CheckConstraint attribute above to: class Meta: models.constraints = [ models.CheckConstraint( check = models.Q(some_count__lt=0) | models.Q(some_count__gt=0), name = 'check_some_count', ), ] The test still failed, with the same error message. I then tried this to check if constraints were being enforced at all: def test_Foo_some_count_field_zero_value(self): foo = baker.make(Foo, some_count=0) self.assertEqual(foo.some_count, 0) To my utter dismay, the test passed - clearly showing that the constraint check was being ignored. I've done a quick lookup online to see if this is a known issue with sqlite3, but I haven't picked up anything on my radar yet - so why is the constraint check … -

How to assign function to button in Django
I am designing a website based on django. I want to update the user information and delete the user if wanted in the same page. I created updating and it works properly. But when I address the delete user function to same html file , the button that I want it to delete user also updates just like the other button. I need both buttons to work for their own purposes.

Django class based view: saved value not loading correctly in a select field
I have a Django 3.2 application running in a production environment, with around 10 simulatenous users. In some of my forms, the saved value for a select field is not loading correctly in the form edit view. This happens after the system is running for a while. If I restart the service, the value loads correctly again on the select field. Some additional information: Django 3.2 / class based views Python 3.8.10 Django default cache system Postgres 12.11 Ubuntu 20.04.4 More than enough RAM and disk space. The model for which the value doesn't load correctly has ~ 130k objects. Sometimes it loads with a void value, sometimes a completely wrong value. Thanks in advance for any hints! best alan
