Celery object has no attribute on_after_configure when trying to start the Celery workers
I want to start the Celery server but whenever I try to do so with celery -A app.tasks worker --loglevel=INFO I get AttributeError: 'Celery' object has no attribute 'on_after_configure'. The code below is defined in the root of the Django project, in a file called tasks.py. app = Celery("tasks", broker="redis://localhost") os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings") @app.on_after_configure.connect def setup_periodic_tasks(sender, **kwargs): sender.add_periodic_task( crontab(hour=23, minute=55), monthly_analytics.s(), ) sender.add_periodic_task( crontab(hour=23, minute=57), calc_average_rating.s(), ) sender.add_periodic_task( crontab(hour=5, day_of_month=1), per_view_payouts.s() ) -
Stripe Checkout - Capturing email and save it in django
My use case requires me to save the users email to a django session. However I don't want them inputting their email twice - in stripe checkout and in my django form. Ideally I want to grab the email they input when making their payment and save that to my django session. Here is my stripe payment.html: <a href="#" id="buy_now_btn" class="btn btn-primary">Buy Now</a> <script src="https://js.stripe.com/v3/"></script> <script> const buy_now_button = document.querySelector('#buy_now_btn') buy_now_button.addEventListener('click', event => { fetch('/checkout/') .then((result) => { return result.json() }) .then((data) => { var stripe = Stripe(data.stripe_public_key); stripe.redirectToCheckout({ // Make the id field from the Checkout Session creation API response // available to this file, so you can provide it as parameter here // instead of the {{CHECKOUT_SESSION_ID}} placeholder. sessionId: data.session_id }).then(function (result) { // If `redirectToCheckout` fails due to a browser or network // error, display the localized error message to your customer // using `result.error.message`. }); }) }) </script> here is my view: def payment(request): return render(request, 'main/payment.html') From what I've seen in my attempts to solve this, it seems stripe obfuscates the info put in at checkout, so I am not sure it is even possible. -

How can I change my project path on Django?
I have a Django project on an ubuntu server v20.04 with apache2. Whenever I run on local, I have to change the TEMPLATES Dir as follow: 'DIRS': ['templates'], Before deploying to the server I am rechanging again: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['/home/crawl/templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] There was no problem when I was using CentOs. After I move to ubuntu I have a path problem. I also add my WSGI and config file.

django cache expensive calculation into database
So I have models like this. class User(CoreModel, AbstractBaseUser, PermissionsMixin): email = models.EmailField( unique=True, verbose_name=_('email'), help_text=_("user's email address"), max_length=255 ) username = models.CharField( verbose_name=_('username'), help_text=_("display name"), unique=True, db_index=True, max_length=32, validators=( MinLengthValidator(2), UnicodeUsernameValidator ) ) avatar = models.ImageField( verbose_name=_('avatar'), help_text=_("user avatar"), upload_to='avatars/', default='avatars/default.jpg', ) is_verified = models.BooleanField( default=False, verbose_name=_('verified'), help_text=_("whether the user's email is verified") ) @property def space_used(self): output_field = models.DecimalField() aggregate = self.upload_set.aggregate( space=Coalesce( models.Sum('size'), models.Value(0), output_field=output_field ), ) return aggregate.get('space') class Upload(CoreModel): size = models.DecimalField( editable=False, verbose_name=_('size'), help_text=_("size in bytes"), max_digits=19, decimal_places=10, db_index=True ) name = models.CharField( blank=True, verbose_name=_('name'), help_text=_("upload name"), max_length=100, validators=( MinLengthValidator(2), ) ) parent = models.ForeignKey( to='uploads.Folder', verbose_name=_('folder'), on_delete=models.CASCADE, null=True, db_index=True ) owner = models.ForeignKey( to=settings.AUTH_USER_MODEL, verbose_name=_('owner'), on_delete=models.CASCADE, editable=False ) file = models.FileField( verbose_name=_('file'), help_text=_("raw file"), upload_to='uploads/' ) As you can see, the space_used property is an expensive operation. If the number of uploads per user increases, then more time will be taken to calculate. Actually, I use this property a lot via my serializers. So, what would be a better approach to improve performance? Have a db field called space_used and update it whenever an upload is created or deleted? Or is there any other better implementation? I don't want to use cached_property because … -
Django REST framework test case order
I want to test the APIs of a Django app. For example I have these APIs: /user/register/ /user/login/ I wrote test.py like this: class UserTest(APITestCase): def test_register(self): # ... # self.assertEqual( ... ) def test_login(self): # ... # login with registered user (test_register function) The test_register works properly but test_login does not work. The user that I created in test_register not exists in database when test_login running. How can I keep the state of database in test process? And how can I set the running order for test class? -
Filter recipients based on ingredients in a panty
so I am trying to create a filter in Django which will be able to return all recipes based on what ingredients a user has in their pantry. So for example: if a user has tomatoes, onions and cabbages in their pantry, the filter should return all recipes with the three listed recipes. I do know this will be a many to many relationship but am confused how to get started and filter recipes based on the multiple ingredients in the pantry. Any help would be appreciated. Thank you -
Trigger a function in Javascript when the Django database get altered
I want a clients browser to run a Javascript function when a row in my Django database gets altered. I am using Django 3.2 and I have hosted my website in Linode using apache2. In simple terms, I want my web browser, to continuously run the query Order.objects.filter(pk=20).first().paid where paid is a boolean value. As soon as the value changes from false to true I want my Javascript to run a specific function. How should I approach this situation, I would like if someone could explain to me a concept and the logic behind this method a what technologies should I use behind this. Do I need to use WebSockets? If so how do I continuously query the database to check for the change? Any help is greatly appreciated! -
How do I upload (image) file to Django server via http?

After uploading the image is stored on server and everything works great. Now I want to create a new object from API client (Android app). How do I send POST request, that contains cookies, basic string fields (artist_id/description/...) and image field? How exactly image field looks like, "image" : "BYTE_ARRAY_OF_IMAGE_FILE"?

Jquery can't add class to dynamicly added nav-link
I have a JQuery code that adds a nav-link dynamicly to a nav-item. The problem is this nav-link doesn't change to active when clicked. I tried to dynamicly give it the active class but it doesn't take it. it seems after the page reloads everything is rest and it's always the first nav-link that takes the active class. Here's the navbar code : <div class="collapse navbar-collapse mt-5 h-100 justify-content-between" id="navbarsExampleDefault" > <ul class="navbar-nav accordion" id="SideBar"> <li class="nav-item"> <a class="nav-link" href="{{index}}">home</a> </li> <li class="nav-item"> <a class="nav-link" href="{{list}}" >list</a> </li> <li class="nav-item"> <a class="nav-link dropdown-toggle" href data-toggle="collapse" data-target="#A" aria-controls="collapseOne" > A </a> </li> <ul class="collapse" id="A" data-parent="#SideBar" > <li class="nav-item"> <a class="nav-link" href="{{B}}" >B</a> </li> <li class="nav-item"> <a class="nav-link" href="{{C}}" >C</a> </li> </ul> And for JQuery here's what I'm doing $('#A').append( '<li class="nav-item">' +'<a class="nav-link" href="{{dynamic_link}}?id=1" >Dynamicly Added</a>' +'</li>') ; $( document ).on( 'click', '.collapse li', function ( e ) { $( this ).addClass( 'active' ).siblings().removeClass( 'active' ); It's of course wrapped inside $(documen).read(). I also tried to wrap it inside $(window).load() but same problem. If you can spot the problem I'd appreciate your guidance. -

When creating a package, how do I manage migrations of a weak dependency?
I have a Django app that I would like to package and offer the community through Pipy. Its only strong dependance is Django. It also integrates nicely with Django CMS and offers additional integration for Django CMS. I plan to offer this additional functionality only to projects with Django CMS installed. (This is what I call a weak dependency - will install and work without it, but work even bitter with it.) Specifically, some models are only defined if the base model CMSPlugin from Django CMS is installed. Is there a good/right way to manage migrations, though? I cannot include migrations of models depending on CMSPlugin in the package since users w/o a Django CMS installations will not be able to run it. If I omit the migrations depending on CMSPlugin users with Django CMS will create them on first installation. I fear, however, that on every update of the package those migrations will be lost on pip install upgrade when the package is overwritten. -

How to give priority to a certain field in SearchFilter fields in django rest framework?
I have a simple search api which search the db based on the query parameter provided to the search keyboard. It works fine, but it has some issues. For example, I have a category named Tv and home appliances. It has products like LG speakers and led tv. I have search qeury parameters for both category name and product name. When I search tv, speaksers products are coming in the first page while tv products are coming in the 5th page which I dont want. It is because, category name has Tv and Home. What I want is tv prodcuts to be appear in the first page while speakers to the other pages. For this I have to prioritise the product name field rather than category name. How to do that?? { id:1 category: TV and Home, product: 1500 W Speakers } { id:2 category: Tv and Home, product: Led Tv 32" } I want id:2 to be appeared first then, the id:1, if I search with Tv. class PrdouctSearchAPIView(ListAPIView): permission_classes = [AllowAny] queryset = Product.objects.all() print(queryset) serializer_class = ProductSerializer filter_backends = [SearchFilter,OrderingFilter] search_fields = ['name','brand__name','collection__name','sub_category__name', 'description','variants__color','category__name'] pagination_class = CustomPagination My local endpoint is: http://127.0.0.1:8000/api/productsearch?search=tv My model: class Product(models.Model): merchant …
