How to match time range if to_date can be Null in Django?
I have two date, let's say from_date and to_date, and I have column with prices for that range. It looks like this in my models: class PriceList(models.Model): from_date = models.DateField(verbose_name="Start date") to_date = models.DateField(verbose_name="End_date", null=True) product = models.ForeignKey(Models, on_delete=models.CASCADE) price = models.DecimalField(verbose_name="EUR/h", max_digits=10, decimal_places=5) I know how to get record for the correct product in a period if a to_date is available, but I am not sure how to fetch it if it is Null, that means from from_date to forever (until changed). And, obviously, would like to have query that will work in both scenarios - if ther is a to_date and if it Null. -

How do I put extrenal link on blog title in Wagtail?
I made Blog-Index-Page on models.py, however I couldn't list it up in other pages, because Blog-Index-Page is a sheet of page so they cannot show on same page. and I want to put external links (URLs) on titles without my Blog-Detail-page. following is the BlogIndexPage on models.py☟ class BlogIndexPage(Page): template = "articles/blog_index.html" blog_title = models.CharField(max_length=100, blank=False, null=True) blog_url = models.URLField(max_length=200, default='DEFAULT VALUE') blog_thumbnail = models.ForeignKey("wagtailimages.Image", null=True, blank=True, on_delete=models.SET_NULL, related_name="+") blog_caption = models.CharField(max_length=100, blank=True, null=True) content_panels = Page.content_panels +[ FieldPanel("blog_title"), FieldPanel("blog_url"), ImageChooserPanel("blog_thumbnail"), FieldPanel("blog_caption"), ] def get_context(self, request, *args, **kwargs): context = super().get_context(request, *args, **kwargs) context["posts"] = BlogIndexPage.objects.live().public() return context I want to apply this class as a listing page, not as detail page.

Fullcalendar cannot display event after event has been created (Django and Javascript)
currently I cannot display event after event has been created. In fact, I cannot display event at all from database. Previously, I made something like this and it worked. views.py def calendar(request): all_events = Events.objects.all() context = { "events":all_events, } return render(request,'fullcalendar/calendar.html',context) calendar.html events: [ {% for event in events %} { title: "{{ event.title}}", start: '{{ event.start|date:"Y-m-d" }}', end: '{{ event.end|date:"Y-m-d" }}', id: '{{ event.id }}', }, {% endfor %} ], But right now, I wanted to insert the part which is in the calendar.html to script.js and I tried to use EventSources but I failed to make events display on fullcalendar. Does anyone know how to convert the part which is in calendar.html to script.js? The reason why I decided to use script.js is because if I put everything in HTML, it will get really long. Currently, my EventSources of script.js looks like this. script.js eventSources:[{ url: '/fullcalendar/calendar', method: 'GET', success: function(){ alert("GOT IT!!"); }, failure: function(){ alert("PROBLEM!!!"); }, } ], it seems I have done nothing but trust me I have searched all over the place and tried so many things but I still fail to make the event display on the fullcalendar.

Django: ValueError: Missing staticfiles manifest entry for 'jquery.twbsPaginationAlt.min.js'
Before marking as duplicate, note that I've checked all the similar questions that have been asked and it has not fixed my problem. I've deployed my Django App on Heroku in in one template where I reference a min.js file, it throws this error in question. My basic directory structure is this: myapp mysite dictionary static jquery.twbsPaginationAlt.min.js staticfiles settings.py: STATIC_URL = '/static/' # STATIC_ROOT = [os.path.join(BASE_DIR, 'staticfiles'), os.path.join(BASE_DIR, 'static/fonts')] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') if DEBUG: STATICFILES_DIRS = [os.path.join(BASE_DIR, 'mysite/static'), os.path.join(BASE_DIR, 'static/')] import django_heroku # handles staticfiles, database url, and secret key, can be overwritten as needed django_heroku.settings(locals(), secret_key=False, logging=False) So originally if STATICFILES_DIRS had any value, I would get an error of FileNotFoundError: [Errno 2] No such file or directory: '/tmp/build_6f3eb879/mysite/static' when running collectstatic on heroku. However, if it is not set, than the fonts I have in my dev environment do not load in properly (I also have fonts inside the base level static folder). This is how I reference the js file in my problem template, it works fine on dev: <script src='{% static 'jquery.twbsPaginationAlt.min.js' %}'></script> For convenience, here is what django-heroku does in terms of staticfiles: logger.info('Applying Heroku Staticfiles configuration to Django settings.') config['STATIC_ROOT'] = os.path.join(config['BASE_DIR'], 'staticfiles') … -

Optimize Serializer Performance in Django Rest Framework
I'm developing a web app using Django and Django Rest Framework and struggling with slow API responses which appear to be based on fetching data from related tables. Test case 1 runs very quickly because the fields are directly tied to the Host model. As soon as I introduce a many-to-many field, it slows down dramatically. Test case 1 - takes 250ms serializers.py class HostSerializer(serializers.Serializer): created = serializers.DateTimeField() last_updated = serializers.DateTimeField() name = serializers.CharField(); Test case 2 - takes 30s serializers.py class HostSerializer(serializers.Serializer): created = serializers.DateTimeField() last_updated = serializers.DateTimeField() name = serializers.CharField(); applications = serializers.SerializerMethodField(read_only=True) def get_applications(self, instance): return [item.name for item in instance.applications.all()] models.py class Host(models.Model): created = models.DateTimeField(auto_now_add=True) last_updated = models.DateTimeField(auto_now=True) name = models.CharField(unique=True, max_length=settings.MAX_CHAR_COUNT) ip_addresses = models.ManyToManyField(IPAddress, blank=True) open_ports = models.ManyToManyField(Port, blank=True) domain = models.ForeignKey('Domain', on_delete=models.CASCADE) applications = models.ManyToManyField(Application, blank=True) tls = models.ForeignKey(TLS, on_delete=models.CASCADE, blank=True, null=True) class Meta: ordering = ['name'] def __str__(self): return self.name def __repr__(self): return self.name def __eq__(self, other): if isinstance(other, Host): return self.name == other.name return False def __hash__(self) -> int: return hash(self.name) def __lt__(self, other): return self.name < other.name views.py class HostList(generics.ListAPIView): """ List all hosts for a given domain """ host_service = HostService() def get(self, request, domain_name, format=None): hosts = self.host_service.find_hosts_by_domain_name(domain_name) … -

How do I revoke JWT everytime a new token generated using django-graphql-jwt?
I am using django-graphql-jwt (https://django-graphql-jwt.domake.io/en/latest/index.html) to handle authentication for my Django Python Graphene application. Currently, everytime a new JWT generated, the previous JWT is still active as long as it does not pass its expiry time. I want to revoke/prevent access to previously generated JWT (even if the JWT is not expired yet) whenever I generate a new JWT. What I am thinking is utilizing the origIat inside the JWT payload and comparing it with something like a last_login attribute from the User model. I noticed though, that User.last_login is not updated whenever I am authenticating using JWT. Still finding how to do this problem properly and wondering if there is any of you already solving this problem before. Thanks! -

Django not creating a testdatabase when testing

How can I get my test setup to use the normal test_dabasename setup again? Im not sure what I have changed to make this happen and am totally stumped. -
