How to create collapsible cards in bootstrap in django template?
I have a table of these collapsible cards with dynamic content in them. The code I have taken from bootstrap looks like this: <p> <a class="btn btn-primary" data-toggle="collapse" href="#multiCollapseExample1" role="button" aria-expanded="false" aria-controls="multiCollapseExample1">Toggle first element</a> <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#multiCollapseExample2" aria-expanded="false" aria-controls="multiCollapseExample2">Toggle second element</button> <button class="btn btn-primary" type="button" data-toggle="collapse" data-target=".multi-collapse" aria-expanded="false" aria-controls="multiCollapseExample1 multiCollapseExample2">Toggle both elements</button> </p> <div class="row"> <div class="col"> <div class="collapse multi-collapse" id="multiCollapseExample1"> <div class="card card-body"> Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident. </div> </div> </div> <div class="col"> <div class="collapse multi-collapse" id="multiCollapseExample2"> <div class="card card-body"> Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident. </div> </div> </div> </div> Problem But as you can see, each collapse is controlled by this attribute multiCollapseExample1. In my django template, when I use this, on clicking any of the close button, only the first card collases because it has a static value of 1. How can I give it a dynamic value so every card opens and closes correctly? Reason I am asking is because … -

How to display friend requests using Django-friendship
I'm trying to implement friendship model in my django project using django-friendship. How do I display the friend requests in the template and what should I pass through the view.

Using Django built in forms and functionality to allow CRUD for anon and registered users
I need to expose Django admin forms to anon or registered users. It seems quite overhead to reproduce the same forms that are found from Django Admin site. For example creating instances for models with foreign keys to other models and to post both at the same time. You need to built all the UI functionality such as Add another, Remove javascript and also table view etc. Can't figure out why since Django seems to have a solution? Is it possible to reuse built in forms? -

Virtual environment packages installation error
I am working on AWS Console Ubuntu server.First of all pip default packages are not installing with pip and whenever we try to install packages in virtual environment,those packages are installing in global.Those packages are not showing while we list pip using pip list command. I tried several times by uninstalling and installing virtual environment as well as pip,but somehow all packages are installing in global not in virtual environment. Expected output is that Pip will list all the installed packages in virtual environment. -
Django: put offline a post after an event
I'm trying to put offline the posts after an event, a definite date. I've developed a simple model for test my aim and inside the model I've put a function(named is_expired) that, ideally, must define if a post is or not is online. Below there is the model: from django.db import models from django.utils import timezone import datetime class BlogPost(models.Model): CHOICHES = ( ("Unselected", "Unselected"), ("One Month", "One Month"), ("One Year", "One Year"), ) title = models.CharField( max_length=70, unique=True, ) membership = models.CharField( max_length=50, choices=CHOICHES, default="Unselected", ) publishing_date = models.DateTimeField( default=timezone.now, ) def __str__(self): return self.title @property def is_future(self): if self.publishing_date > datetime.datetime.now(): return True return False @property def is_expired(self): if self.membership == "One Month": def monthly(self): if publishing_date + datetime.timedelta(days=30) >= datetime.datetime.now(): return True if self.membership == "One Year": def yearly(self): if publishing_date + datetime.timedelta(days=365) >= datetime.datetime.now(): return True return False class Meta: ordering = ['-publishing_date'] For show a list of all expired posts I use this simple template: {% for p in posts_list %} {% if p.is_future or p.is_expired %} <div class="container my-4 bg-primary"> <h3><a class="text-white" href="{{ p.get_absolute_url }}">{{ p.title }}</a></h3> <h5>Data di pubblicazione: {{ p.publishing_date|date:"d - M - Y | G:i:s" }}</h5> {% if p.is_expired %} <p>Expired? … -
Correctively Django query datetime for data/object one hour from now
i am filtering Django query to getting updatetime last one hour from now, The model has a DateTimeField. this is for getting all updatetime that update one hour ago, i've tried using datetime.now() - timedelta(hours = 1), and using range(min,max) onehours = datetime.now() - timedelta(hours=1) queryset = TbDevice.objects.filter(updatetime__gte=onehours).order_by('-updatetime') this codes should return updatetime from last hour ago, but actually the queryset return all data with "date" is today -
Error overriding get method in Django Rest
I am new to Django Rest Framework. In my work I was suggested to work in an existing project and learn the Rest Framework on the fly. So I was writing an api to display the vehicle-list with both the get_queryset method and the get method. I could make the get_queryset() method work, but the get() method isn't working (I'm assuming some kind of syntax error). The working code : class VehicleList(ListAPIView): permission_classes = (AllowAny,) serializer_class = FleetVehicleSerializer def get_queryset(self): domain = self.request.META.get('HTTP_DOMAIN', None) if domain is None: raise Exception("Domain is missing in request header") qs = FleetVehicle.objects.using(domain).all() return qs Not working code: class VehicleList(ListAPIView): permission_classes = (AllowAny,) serializer_class = FleetVehicleSerializer def get(self, request): domain = self.request.META.get('HTTP_DOMAIN', None) if domain is None: raise Exception("Domain is missing in request header") vehicles = FleetVehicle.objects.using(domain).all() return Response({'a': vehicles},status=status.HTTP_200_OK, content_type = 'application/json' ) The output is supposed to be a json, I am testing the api in postman. Can anyone help me with the possible syntax error?
