Why GIthub Folder Button broken?
I git pushed my projected to my Github page, but a few important folder didn't seem to work and can't see the content. And even when I download all folders in zip file, still nothings contained in it. I mean, the start folder should contain all of my files and activated. The original folder has full content, so I have no idea what to do. Noghing errors thrown while I push those to Github. -

django-allauth accounts/signup gets [WinError 10061] No connection could be made because the target machine actively refused it
I know that there are a lot of answers to this issue say that I should probably try running my server on another port like so: python manage.py runserver 0.0.0.0:8080 I have tried that didn't fix it. I have turned off my windows Norton firewall: I have started PyCharm as administrator. The thing that make me think these solutions were not going to work for me was that other API endpoints work fine: http://localhost:8000/accounts/login/ works and http://localhost:8000/accounts/logout/ works too. But when I fill out the form and POST my data to http://localhost:8000/accounts/signup I get this error: OSError at /accounts/signup/ [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions Request Method: POST Request URL: http://127.0.0.1:8000/accounts/signup/ Django Version: 2.2.7 Exception Type: OSError Exception Value: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions Can someone please tell me what I am missing here? -
Edit existing instance of a model
I have created a form to create an instance of my car dealer model. Now I want to be able to click on an edit icon and be taken to a page with a form that is prepopulated with the attributes of the model instance.

Django include static CSS JS files - path included but not read
My project base directory is, then app and static dirs as below. I am trying to load CSS and JS.

django paginationated first page content different to root page content (with cache)
I am paginating content based on a random queryset and I seem to be getting inconsistent results between the paginated first page ?page=1 and the root page itself. So, I have my ListView like so: class Some1_ListView(ListView): model = Some_Model template_name = "test1.html" paginate_by = 12 context_object_name = "test1" queryset = Some_Model.objects.all().order_by('?')[:24] My urls is like so: urlpatterns = [ path('test1/', cache_page(500)(Some1_ListView.as_view()), name="test1" ), ] and the template is paginated according to the django docs, nothing special. Now, when I go to: localhost/test1 I get the first 12 objects. Now, When I move to the next page, onbiously, my url becomes: localhost/test1/?page=2 This renders fine aswell. Now, when I go back to localhost/test1/?page=1 I see that the results are not the same as localhost/test1/ So, localhost/test1/?page=1 != localhost/test1/ Since I was caching the URL, I was expecting these two to be the same. Can someone enlighten me as to why this is? and how do I get aorund it? Id like both these pages to show the same content (from cache). -
Recommendation on deploying a heavy Django + React.js web-application
I got to build a Django application recently that has a database and performs some floating-point operations( biopython, alpha-shapes and similar algorithms on crystallographic data from the database) upon request from the React.js frontend. I was wondering what would be the best way to deploy something like this long term and how the two codebases would communicate with each other ( runs well on localhost as of now ). I've come across a few suggestions like digital ocean for django and firebase for the frontend, and heroku of course. I have never, however, hosted a website that would go into production eventually, let alone two, and am a little at a loss as to how the two codebases would communicate with each other, how to preserve all the packages installed in django's virtual environment in deployment, how to transfer online the database to which the calls are made. I would appreciate any pointer to resources to read up on or an architecture suggestion very much. Thanks a ton! -

How to automatically translate models of a django webapp
I need to translate an ecommerce webapp built with Django-Oscar. I got the system language translated, so now I'm focusing only in translating the product names, product descriptions and the categories names. There are hundreds of products, and new ones will be added. So using the method where I have to manually insert translations in the .po files doesn't look like a good idea. I am considering to use the google translation API. I have watched a tutorial just with python. I would like to know if this is suitable for Django? Will this make the app slow? Are there better alternatives? Success Jaime -
Django: 404 URL not found when linking to a new url via the homepage
so I'm new to Django and have been having an issue adding a new page to my website. The home page and blog detail page are working fine. The issue arises when I try to link to an "About me" page.

Django IntegrityError with uuid as primaryKey
Okay so here is the behaviour explained. 1. I create a new Post object via admin panel. 2. Object is saved. 3. Create one more Post object after that. 4. Get error django.db.utils.IntegrityError: duplicate key value violates unique constraint "lp_post_pkey" DETAIL: Key (id)=(5de7b062-14b2-42ef-a9ee-95bbb17ccf3b) already exists. I have read duplicate key value violates unique constraint in django . The problem is probably the same that my primary key sequence in the table i'm working with has become out of sync. And the solution to that was to set the current Primary Key from maximum +1. But i'm using uuid's for my primary key, that probably isn't the solution for me. So, how can i sync my primary keys if the problem really is at that? Btw, when i reset the local server i can repeat the steps from 1-4. As well, i've noticed when i'm doing a manage.py makemigrations even when i have nothing to migrate, my uuid fields keep altering to new ones. Can the problem be somehow related? models.py class SubscriberModel(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4(), unique=True, editable=False) email = models.EmailField() subscribed = models.DateTimeField(default=timezone.now()) ip_addr = models.CharField(null=False, max_length=250, default="") objects = models.Manager() def __str__(self): return "{%s}/EMAIL\{%s}/\Subscribed On/\{%s}/\From this IP" % … -
Juggling customer data in Django
I want to build a web app with Django which should be multi-client capable. Now I'm facing the question of how to juggling with the customer data. Of course, I want to make sure information from one client does not leak to the other, but what is the best way to do it? Does Django provide any permissions or something else for this job or should I store the client in all db tables and work with queries instead? What is the state of the art approach for this use case? I'm new to web dev, so please be indulgent. :) -

Sidebar disappears permanently upon resizing
I have a problem with the responsiveness of a website I am currently creating. The problem occurs upon resizing (in chrome and firefox): I have a sticky sidebar (sb1) that I want to show whenever screen width is > 1024 and another that I want to show when the screen width is < 1024 (sb2). I can get sb1 to hide and s2 to show when it is < 1024. However, once I resize the window again, so that it is > 1024, sb1 doesn't show. Curiously, the same thing doesn't happen to sb2 upon resizing. As sb2 works, I won't provide the code for that, but I am using the script below. I have tried to get this to work using media queries and javascript. Here is the HTML: <div id="sticky-sidebar-demo" class="toc-sidebar"> <div class="sidebar__inner"> <h4> table of contents </h4> <div class="js-toc"></div> </div> </div> CSS: #sticky-sidebar-demo { float: left; width: 200px; will-change: min-height; } #sticky-sidebar-demo .sidebar__inner{ position: relative; transform: translate(0, 0); transform: translate3d(0, 0, 0); will-change: position, transform; } .inner-wrapper-sticky { overflow: hidden; } I've tried @media only screen and (max-width: 1024px) { #sticky-sidebar-demo { display: none; }} hoping that that would hide the sidebar (sb1) when the screen was … -

Stripe API requests being split sent across two Stripe accounts
We have a Django project that needs to use two different Stripe accounts (for compliance reasons). One Stripe account ("SA1") is for SaaS billing and our second Stripe account ("SA2") processes specific one-time payments using Stripe Connect. After we set this up, I'm seeing unexpected behavior where requests are being split sent between both accounts, rather than going to the intended SA1 account. Some API requests get sent to SA1 (what we want), some API requests are sent to SA2 (what we do not want). I will explain further: we have a view admin_billing where new customers save their card to create and save a new Stripe Customer and their Card. def admin_billing(request): """ Query customer table and adds a new card. :param request: :return: Billing rendering with template """ form = StripeAddCardForm(request.POST or None) if form.is_valid(): customer = Customer.objects.get_or_create_for_user(request.user) token = form.cleaned_data['stripeToken'] card = Card(customer=customer, stripe_card_id=token) try: card.save() except stripe.error.CardError as e: body = e.json_body err = body.get('error', {}) messages.error(request, err.get('message')) log.error("Stripe card error: %s" % (e)) except stripe.error.StripeError as e: messages.error(request, 'Please try again or report the problem') log.error("Stripe error: %s" % (e)) except Exception as e: messages.error(request, 'Please try again or report the problem') log.error("Error while handling … -
