How do I fix overlarge button (or over-small panel header) in django-bootstrap3?
I have been working on a django project recently and am having problems with one of the templates. I am revising a dashboard to use bootstrap3 drop-down panels, but the toggle buttons are larger than the panel headers. I have tried the advice from a few other answers with no luck. This is my first time using bootstrap so I'm running from mostly basic django tutorials and a W3Schools series. I've tried advice from a few other answers and sites but only succeeded in getting myself confused. I did manage to get the panel header to expand, but that left my title right at the top of the header (instead of centered) and me completely confused, so I backtracked to the code I have here. My code looks like this: <div class="panel panel-default"> <div class="panel-heading"> <div class="pull-right"> <button data-toggle="collapse" data-target="#orders" class="btn btn-primary">+</button> </div> <h3 class="panel-title my-auto">Orders</h3> </div> <div class="panel-body collapse" id="orders"> {% for order in orders %} <p>{{order}} <a href="{% url 'view_order' order.id %}">View</a></p> {% empty %} <p>No outstanding orders. Time to get more business!</p> {% endfor %} </div> </div> And here is a screenshot of how it comes out: screenshot -

How to keep Django 2.2 migrations on Kubernets while developing?
I have a rather complex K8s environment that one of the Deployments is a Django application. Currently we are having a very hard time whenever I need to update a model that has already been migrated to a PostgreSQL database. Let's say for instance that I create an application named Sample, that has a simple table on the models.py. My development process (skaffold) builds the docker and apply it locally on the minikube, after this is done I connect to the pod via kubectl exec and execute the python manage.py makemigrations and python manage.py migrate, so far so good. After some time, let's say I need to create a new table on the models.py file of the Sample application, the skaffold builds the docker, kills the old pod, and create the new pod. So I connect as usual via kubectl exec and try to execute the makemigrations and migrate command, lo and behold, there's no migration to apply. And of course no change is made on the PostgreSQL. Upon further searching this, I believe that the reason for this is that since the docker is built without the Sample/migrations folder, and there's already a table (the original one) on the … -
Using Python 3.9 and Django 3.1.3 server crashes when re-launched
this is my first question at Stack overflow. I have been learning Python for about a month and Django for two weeks.

How to Preventing duplicate signals by using dispatch_uid
I am using a signal to send a notification to the Authors when a new activity such as a User clicking a like button to a post. I am having a side effect of using the signal which is when a user creates a new post and a user likes the post, the author receives 2 notifications instead of just 1. I have searched for several answers but they affected other sides of the project so I found on the Django documentation that using a dispatch_uid="my_unique_identifier" will fix these problem. https://docs.djangoproject.com/en/3.1/topics/signals/#preventing-duplicate-signals I have made a trial but it didn't work out. So here it is: Here is the Like model.py class Like(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) value = models.CharField(choices=LIKE_CHOICES, default='Like', max_length=8) updated = models.DateTimeField(auto_now=True) created = models.DateTimeField(auto_now=True) def __str__(self): return f"{self.post}-{self.user}-{self.value}" def user_liked_post(sender, instance, *args, **kwargs): like = instance if like.value=='Like': post = like.post sender = like.user dispatch_uid = "my_unique_identifier" notify = Notification(post=post, sender=sender, user=post.author, notification_type=1) notify.save() def user_unlike_post(sender, instance, *args, **kwargs): like = instance post = like.post sender = like.user notify = Notification.objects.filter(post=post, sender=sender, user=post.author, notification_type=1) notify.delete() def like_progress(sender, instance, *args, **kwargs): like = instance post = like.post sender = like.user dispatch_uid = "my_unique_identifier" if … -

The value of the Like button is Like Notification sent to the Author of the Post The same user clicks the Like button again. The value of the Like button is Unike Nothing happens What I want is the previously sent notification to be deleted Here is my Models.py related to the Post Model: class Post(models.Model): title = models.CharField(max_length=100, unique=True) author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='author') num_likes = models.IntegerField(default=0, verbose_name='No. of Likes') likes = models.ManyToManyField(User, related_name='liked', blank=True) Here is the views.py: class PostDetailView(DetailView): model = Post template_name = "blog/post_detail.html" def get_context_data(self, … -

How do I pass the correct request to the methods which is not HttpRequest but the DRF 3 Request I suppose. class AddInvoice(APIView): @staticmethod def process_request(request, *args, **kwargs): if isinstance(request, HttpRequest): return Request(request,parsers=[MultiPartParser, FormParser, JSONParser, DjangoMultiPartParser]) return request parser_classes = (MultiPartParser, FormParser, JSONParser, DjangoMultiPartParser, FileUploadParser) def dispatch(self, request, *args, **kwargs): response = None #request = AddInvoice.process_request(request, *args, **kwargs) if request.method == 'PUT': if request.path.rstrip('/') == '/invoice/digitize': response = self.digitize(request,*args, **kwargs) elif request.method == 'GET': if request.path.startswith('/invoice/isdigitized/'): response = self.isdigitized(request, *args, **kwargs) elif request.path.startswith('/invoice/get/'): response = self.get(request, *args, **kwargs) elif request.method == 'POST': if request.path.rstrip('/') == '/invoice': response = self.post(request, *args, **kwargs) if not response: response = Response(status=status.HTTP_406_NOT_ACCEPTABLE) if not getattr(request, 'accepted_renderer', None): neg = self.perform_content_negotiation(request, force=True) request.accepted_renderer, request.accepted_media_type = neg response.accepted_renderer = request.accepted_renderer response.accepted_media_type = request.accepted_media_type response.renderer_context = self.get_renderer_context() return response -
Django - ensure there is only one ACTIVE product per user
Having this model class Product(models.Model): user = models.ForeignKey(...) STATUS_ACTIVE = 'active' STATUS_CANCELLED = 'cancelled' STATUS_DRAFT = 'draft' STATUS_CHOICES = ( (STATUS_ACTIVE,'Active'), ... ) status = models.CharField(..., choices=STATUS_CHOICES) I'm trying to figure out how to make User model having only one product that is ACTIVE. User is allowed to have any number of CANCELLED and DRAFT products, but only one can be ACTIVE. I'm thinking about CheckConstraint but I can't figure out such query. -
How do I get images to show on my django app?
On my Django app, I am trying to make an eBay type of site that lets people post listings with pictures and bid on them. Everything works except posting an image. The image won't show and I do not know if it's the HTML or the python. If you have any questions let me know. Html code: {% extends "auctions/layout.html" %} {% block body %} <div class="container"> <h2>Create listing</h2> </div> <div class="container"> <form action="{% url 'submit' %}" method="POST"> {% csrf_token %} <div class="form-group"> <label for="exampleFormControlInput1">Title</label> <input type="text" class="form-control" id="exampleFormControlInput1" placeholder="Title of the lisiting..." name="title" required> </div> <div class="form-group"> <label for="exampleFormControlTextarea1">Description</label> <textarea class="form-control" id="exampleFormControlTextarea1" rows="5" placeholder="Description..." name="description" required></textarea> </div> <div class="form-group"> <label for="exampleFormControlSelect1">Category</label> <select class="form-control" id="exampleFormControlSelect1" name="category" required> <option>Fashion</option> <option>Tools</option> <option>Toys</option> <option>Electronics</option> <option>Home accessories</option> <option>Books</option> </select> </div> <div class="form-group"> <label for="exampleFormControlInput1">Initial Bid</label> <input type="number" class="form-control" id="exampleFormControlInput1" placeholder="Starting bid..." name="price" required> </div> <div class="form-group"> <label for="exampleFormControlInput1">Image link (optional)</label> <input type="text" class="form-control" id="exampleFormControlInput1" placeholder="https://blah-blah.jpg..." name="link"> </div> <button class="btn btn-outline-info" type="submit">Submit</button> </form> </div> {% endblock %} This is the python function for making listings: def create(request): try: w = Watchlist.objects.filter(user=request.user.username) wcount=len(w) except: wcount=None return render(request,"auctions/create.html",{ "wcount":wcount }) -
Shared configuration across python threads/modules
Something very simple (python!) gone very very bad: I have a Django service app - main thread create a selenium service and keeps its parameters (for all that it matters a string) in a global variable. Another thread that handles a request is required to access this global string with the shared service address (and actually pass it to another thread, but let's leave that for now). There seem to be no sane way to do that. Not without using shared memory or database. I suspect python has better means of sharing data across threads/modules? -
How do I get object in JavaScript/HTML from Django by ID?
I'm doing a small clinic project using Django. In one page of all html pages I would like to create big buttons in which I have data of specific appointment(id, title, doctor, patient, start hour, end hour). It looks like: APPOINTMENT BUTTON There are the fundamental files: models.py class Appointment(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=100, default=defaultTitle) description = models.CharField(max_length=480, null=True, blank=True) start_date = models.DateTimeField(null=True, blank=True, default=datetime.date.today) end_date = models.DateTimeField(null=True, blank=True, default=datetime.date.today) doctor = models.ForeignKey(User, on_delete=models.CASCADE) patient = models.ForeignKey(User, null=True, on_delete=models.SET_NULL, related_name='+', blank=True) def __str__(self): return self.title views.py def doctortoday(request): today = datetime.date.today().strftime("%d.%m.%Y") today_appointments = None if request.method == 'GET': today_min = datetime.datetime.combine(datetime.date.today(), datetime.time.min) today_max = datetime.datetime.combine(datetime.date.today(), datetime.time.max) try: today_appointments = Appointment.objects.filter(doctor=request.user, start_date__range=(today_min, today_max)) except: today_appointments = None context = { 'today': today, 'appointments': today_appointments } return render(request, 'doctortoday.html', context) If we click the appointment button then will show popup modal. At the moment there is only QuerySet - {{ appointments }}. POPUP MODAL And the my major problem - how can I display in the popup modal the specific appointment's data without refreshing page?
