Loading HTML into <div> element in Electron app, then loading subsequent links into same <div>
I'm developing an app for basic student management. I have an Electron app with a main content <div>, and I have jQuery load the response from "http://127.0.0.1:8000" (localhost). I'm running Django (back-end is being made in Python) for my back-end, and since it's a local app, there's no need to change the request to an actual website. Once the jQuery loads the initial page, with the login and such, I need subsequent links (the login button, home button, any link that's shown on the app) to be loaded into the main content <div> instead of redirecting the entire Electron app to that URL. I've tried running it in a web browser as opposed to in the Electron app, and everything works as intended. My code in the Electron app for loading the app: <div id="content" class="bg-light"> <div id="app-container"> <div id="page" style="z-index: 10;"></div> <script> // load page using jQuery $("#page").load("http://127.0.0.1:8000"); </script> </div> </div> I expect the content to update with the response from a link, instead of the Electron app's URL being redirected to it. Thanks in advance guys! -
Chrome err_connection_reset on lte connection
So I have very weird problem. So I have website and when I'm connected through wifi everything is fine, chrome and mozilla are loading my website. But when I switch to LTE internet my website is working fine only on mozilla. Chrome is throwing ERR_CONNECTION_RESET error. I tried turning off firewall and restarting server, but it doesn't change anything. Website was made in django. On the other hand when I'm connecting directly to ip, it's working (I see 404 from apache, but that's becouse it's configurated to work with domain). I'm using also certbot, but it's not looking like certbot fault. It's rather something connected with domain conguration. I'm using OVH services both for server and domain. In domain I added only ip4 and ip6, dns servers were left in default configuration. -
Difference between different ways to create celery task
I am very confused by looking at different ways of creating a celery task. On the surface they all work the same So, Can someone explain what is the difference between these. 1. from myproject.tasks import app @app.task def foo(): pass 2. from celery import task @task def foo(): pass 3. from celery import import shared_task @shared_task def foo(): pass I know by a little bit of googling that the difference between the 1nd and 3rd one is shared_task is used when you don't have a concrete app instance. Can someone elaborate more on that and when is the second one is used? -

Why is my ModelChoiceField showing three forms instead of two and why is it not reading my choices?
First of all, I have two model forms fused into one form and they are supposed to show topic name and question type, but for some reason, three forms are showing up and the first one is not showing choices where the second one is showing up two times, and I don't want the second one which is the one with the choices showing up in it because my CSS are not applied on it.

Django: Method Not Allowed (POST):
I am trying to create an event in FullCalendar by passing a timestamp into the url of a Django CreateView. However, after pressing submit on my form I keep getting a blank page and the error: Method Not Allowed (POST): /fullcalendar/ambroses-calendar/ html: dayClick: function(date, jsEvent, view) { if($('#calendar').fullCalendar('getView').type != 'month') { $("#occDiv").load("{% url 'edit_occurrence_short' 1234567898765 %}".replace(1234567898765, (new Date(date)).getTime())).dialog({ autoOpen: false, modal: true, bgiframe: true, width: 800 }); $("#occDiv").dialog('open'); } urls.py url(r'^occurrence/add/(?P<date>\d+)/$', ShortCreateOccurrenceView.as_view(), name='edit_occurrence_short') Views.py: class ShortOccurrenceMixin(CalendarViewPermissionMixin, TemplateResponseMixin): model = Occurrence pk_url_kwarg = 'occurrence_id' form_class = ShortOccurrenceForm class ShortCreateOccurrenceView(ShortOccurrenceMixin, CreateView): template_name = 'schedule/edit_occurrence_short.html' def form_valid(self, form): occurrence = form.save(commit=False) start = datetime.datetime.fromtimestamp(self.kwargs.get('date', None)/1000.0) end = start + datetime.timedelta(hours=1) occurrence.start = start occurrence.end = end occurrence.save() return HttpResponseRedirect('home') Models.py: class Occurrence(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE, verbose_name=_("event")) title = models.CharField(_("title"), max_length=255, blank=True) description = models.TextField(_("description"), blank=True) start = models.DateTimeField(_("start"), db_index=True) end = models.DateTimeField(_("end"), db_index=True) cancelled = models.BooleanField(_("cancelled"), default=False) original_start = models.DateTimeField(_("original start"), auto_now=True) original_end = models.DateTimeField(_("original end"), auto_now=True) created_on = models.DateTimeField(_("created on"), auto_now_add=True) updated_on = models.DateTimeField(_("updated on"), auto_now=True) Forms.py: class ShortOccurrenceForm(forms.ModelForm): class Meta(object): model = Occurrence fields = ('title', 'event') -
Deeping in M2M Queries
I have the following queryset which retrieves publications of the followers of the current user. followers is a M2M field of User to itself (many users to many users). Publication.objects.filter(user__in = self.request.user.followers.all()).order_by('created') As a recommendation system, I want to retrieve by a similar query the publications of followers of followers of a user, or followers of followers of followers of [...nsteps] of him. How can I do that? The idea would be something like this: Publication.objects.filter(user__in = self.request.user.followers.all().followers.followers).order_by('created') If possible, a would like to not evaluate querysets or evaluate as less of them as possible for efficiency.
