Restrict new form creation on frontend in Django
How can I restrict new form creation using Django formset? For eg. I want to present an "Add row" button to the user which will duplicate a set of input fields, AND, when the number of rows reaches 10, I want to give a prompt to the user that no more rows can be created. For eg., in the image below, if the user clicks on "+" one more time, it should either do nothing or prompt the user that max number of rows reached or something like that. -

Insert cv.imshow in a frame in Django
I need to encapsulate rtsp streaming in Django page. I'm actually using openCV, to take a frame and show it using StreamingHttpResponse().

How can I present data from a model that inherits across multiple web pages?
I'm making a form divided into several pages (like a wizard form), I could not implement it and reviewing, Wizard is not what I need, so I divided it into pages.

How do I show that information that has already been saved? views.py class step7(ListView): model=Presupuestos template_name='Presupuestos/new-estimate-7-preview.html' context_object_name='presupuestos' queryset=Presupuestos.objects.all() models.py class Presupuestos(models.Model): cliente= models.ForeignKey(Clientes, on_delete=models.SET_NULL, null=True) carro=models.ForeignKey(Carro, on_delete=models.SET_NULL, null=True) mano_obra=models.ForeignKey(ManoObra, on_delete=models.SET_NULL, null=True) parte=models.ForeignKey(Parte, on_delete=models.SET_NULL, null=True) garantia=models.CharField(max_length=255,default=0) pago = models.ForeignKey(Pagos, on_delete=models.SET_NULL, null=True) foto = models.ForeignKey(Foto, on_delete=models.SET_NULL, null=True) tecnicos=models.ForeignKey(Tecnicos, on_delete=models.SET_NULL, null=True) #detalle=models.ForeignKey(Detalle, on_delete=models.SET_NULL, null=True) def __str__(self): return f'{self.cliente} {self.carro}{self.mano_obra} {self.parte}{self.garantia}' \ f'{self.pago}{self.foto}{self.tecnicos}' new-estimate-7-preview.py <div class="invoice-title"> {% if presupuestos %} <h4 class="float-end font-size-16">Estimate #0001 <span class="badge bg-success font-size-12 ms-2">Paid</span></h4> <div class="mb-4"> <strong>LOGO</strong> </div> {% for presupuesto in presupuestos %} <div class="text-muted"> <p class="mb-1"><i class="uil uil-envelope-alt me-1"></i> {{presupuestos.cliente}}</p> <p class="mb-1"><i class="uil uil-phone me-1"></i> {{presupuestos.carro}}</p> </div> {% endfor %} {% endif %} </div> -
dealing with long form submission times
When a user creates a post it is broken into two forms one with the details one with the images. However if the user is uploading a lot of images the form can take a few minuets to submit leaving the user waiting at the create a post screen. Is there any way I can return the first form and then have the image upload and compression work in the background? Or is there a better way to handle this if postForm.is_valid(): PostFormID = postForm.save(commit=False) PostFormID.author = request.user PostFormID.save() if len(request.FILES.getlist('images')) == 0: return redirect('post-detail', PostFormID.pk , PostFormID.slug) else: for f in request.FILES.getlist('images'): postImages = PostImagesForm(request.POST, request.FILES) if postImages.is_valid(): instance = postImages.save(commit=False) instance.post_id = PostFormID.id instance.images = f instance.save() return redirect('post-detail', PostFormID.pk, PostFormID.slug) -
Query Performance Optimization in Django
I am creating a Blog website in django and while creating a page for specific blog posts I came across a problem in querying the data using the ORM. I have a model for Post which is related to another model comments where all the comments are captured. The comments model have following fields -> class Comment(models.Model): comment = models.TextField(null=True) Created_date = models.DateTimeField(auto_now_add=True) Updated_date = models.DateTimeField(auto_now=True) post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments_post') user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='comments_user') def __str__(self): return self.comment Now while Querying the single blog post there could be N number of comments and for each comment there is a user assigned who has written the comment. So I want to find the user details such (name, email or phone number) for the user for each comment. The Query that I have executed is -> post = Post.objects.select_related().prefetch_related('images_set','comments_post').get(id=post_id) Now when I try to use {{post.user.email}} and if there are 3 comments for the post, the ORM will query 3 times to the DB to find the email for each user. But if I use {{post.user_id}} it will query only once as it preloads the user_id as it is available in comments table. Is there any way I can make … -

How to pass two PK through urls in Django?
I've created a function that adds the user to an event, that is working fine but, i'm having problems with the one that removes the users from the event, I didn`t figure out how to get the attendant so that the owner can remove it. By now, I have this: views.py (Function that adds the user to the event) @login_required def request_event(request, pk): previous = request.META.get('HTTP_REFERER') try: post = Post.objects.get(pk=pk) Attending.objects.create(post=post, attendant=request.user) messages.success(request, f'Request sent!') return redirect(previous) except post.DoesNotExist: return redirect('/') (Function that removes users from the event, handled by the event owner) @login_required def remove_attendant(request, pk, id): previous = request.META.get('HTTP_REFERER') try: post = Post.objects.get(pk=pk) attendant = Attending.objects.get(id=attendance_id) Attending.objects.filter(post=post, attendant=attendant).delete() messages.success(request, f'User removed!') return redirect(previous) except post.DoesNotExist: return redirect('/') Urls.py path('post/(?P<pk>[0-9]+)/remove_attendant/(?P<attendance_id>[0-9]+)$', views.remove_attendant, name='remove-attendant'), Any help or comment will be very welcome! thank you!!! -

Django 3.2.1 KeyError in admin panel "django/db/models/fields/related_descriptors.py", line 173
I have models set up like the following: class A(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=50) def __str__(self): return self.name class B(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) a = models.ForeignKey(A, on_delete=models.CASCADE) def __str__(self): return self.a.name class C(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) b = models.ForeignKey( B, on_delete=models.CASCADE, related_name="c_name" ) def __str__(self): return self.b.a.name When I access C in the admin panel, I'm getting the following error: KeyError: 'a' File "django/db/models/fields/related_descriptors.py", line 173, in __get__ rel_obj = self.field.get_cached_value(instance) File "django/db/models/fields/mixins.py", line 15, in get_cached_value return instance._state.fields_cache[cache_name] I can't seem to find anything that explains why this would fail. I have looked at the underlying data (via psql) and the foreign keys are pointing to the right models etc. -

But its showing raw html and css tags ! What's the solution ? -
Making SQS boto3 base class python
Need a help with writing base class for Amazon SQS boto3 client. The idea is that we will have three classes, one parent and two child. In the parent class there are all base functionality to connect to AWS SQS and child will be with custom body and URLs. (because there will be different body and URLs from each other) So I don't understand where need to create send function in the main class or in a child? And the basic structure of the classes, there is no information for this case on the internet, please help. What I have done at the moment: import boto3 import logging from abc import ABC, abstractmethod from django.conf import settings logger = logging.getLogger(__name__) class BaseQueueController(ABC): """" Base controller for Amazon SQS """ def __init__(self): self.sqs = boto3.client('sqs', region_name=settings.AWS_REGION, aws_access_key_id=settings.AWS_SQS_ACCESS_KEY_ID, aws_secret_access_key=settings.AWS_SQS_SECRET_ACCESS_KEY, endpoint_url=settings.AWS_SQS_ENDPOINT_URL, ) @abstractmethod def send(self): pass class FirstChild(BaseQueueController): """" SQS 1st """ pass class SecondChild(BaseQueueController): """" SQS 2nd """ pass
