Form will not show in Django
So I am trying to show a dropdown menu with Django 2.x (latest version) for an ecommerce site that allows you to select the quantity of an item before adding to cart but the quantity form is not showing.

How to pass multiple queries in url to Django
my urls.py setting is path('somepath', views.somefunc.as_view(), name='SomeFunc') SomeFunc takes POST and is supposed to take some query commands like localhost:8000/path/to/somepath?a=f&b=g When I print out the request itself, it seems like it's only reading POST /path/to/somepath?a=f and I cannot get anything from request.POST How do I read both a and b? This is Django2.0 by the way -

How to call Python functions from JavaScript in Django?
I've been struggling on this for a couple days. I've read through many posts, blogs, and watch video demo on Django projects, but nothing quite answers my problem. I have a Django webapp that uses a Python API to connects to a third-party service to analyze text data. The user writes into a text area, presses the button, then the text is sent to the service which returns a list of JSON objects. The API call to this service is a Python function. I'm trying to use Ajax to make an async call to the Python function using the text data as a param when the button is pressed. I'm not at this time trying to invoke my third-party service, yet. I'm just trying to see if I can get a response from Python sending input and receiving output. Most of the examples I've found involve creating a form and submitting it so the Django framework automatically calls it's Python functions. A form is not exactly what I'm trying to build, nor am I wanting to proceed to a new page to see the results or refresh the current one. <!-- index.html --> <html> <head> <title>Test Data</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> <script> … -

django test server error: connection refused. How to deploy apps locally to test?
This is the first time I've developed a web app using Django and one of my first major attempts at programming. I'm trying to deploy my project to the django test server- http://127.0.0.1:8000/ -but I get an error that says the connection is refused. I've looked through Django's documentation and and other websites about django deployment but I'm at a loss on how to troubleshoot this error. If someone can recommend a way for me to deploy django locally so I can test my web app using django test server or recommend another deployment service that is easy for new programmers to use that would be very appreciated.

Static_Root in settings.py redirecting to my static folder in app instead of base root
I am having a hard time deploying a project to heroku, because it says it cannot find the static files. My static files are in an app called 'social' in a folder called 'static', they aren't in the base directory where manage.py is. --p_12 (folder)- settings.py --social (folder) -static (folder) - css, images, javascript --manage.py The heroku docs says to put this in your settings.py: STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) So my question, how do I get this to point to my static folder in my social app. I've honestly tried for like an hour on this. Thanks for your help. -
Django DEBUG weirdness in IIS: DEBUG=False still runs in debug mode
Summary: My site is running in DEBUG mode even though settings are set to DEBUG = False. FYI, I've researched this and found some excellent responses and testing ideas in these related questions (none of which helped, even though logically they SHOULD have): django DEBUG=False still runs in debug mode and Heroku Django DEBUG Setting not applied IIS FastCGIHandler environmental variable: Name = DJANGO_DEBUG Value = False Note: Removing this environmental variable causes a 500 error regardless of setting in production.py. settings/production.py: Different scenarios tried in settings/production.py using env variable set to False in my FastCGIHandler: DEBUG = os.environ.get('DJANGO_DEBUG', False) RESULT: Site runs in Debug Mode DEBUG = bool(os.environ.get('DJANGO_DEBUG', False)) RESULT: Site runs in Debug Mode DEBUG = False (hardcode w/o env var) RESULT: Site doesn't work, returns 500 page and error tracking gives ValueError: Missing staticfiles manifest entry for 'images/favicon/manifest.json' which is a very bizarre and misleading error. Other actions taken: I've checked both the base.py and production.py files for any other references to DEBUG or to the DJANGO_SETTINGS variable and they are clear. I also searched other .py files that the IIS server interacts with (wsgi.py, manage.py). I have even tried setting DEBUG = False in the base.py … -
Django postgres SearchVectorField from foreign key

Django not collecting static files to S3 bucket but local directory, what's wrong with the config?
So I have my settings.py set up as so: STATIC_ROOT = os.path.join(BASE_DIR, 'my_dir/static/') STATICFILES_FINDERS = [ 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', 'django.contrib.staticfiles.finders.DefaultStorageFinder', ] AWS_ACCESS_KEY_ID = config('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = config('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = config('AWS_STORAGE_BUCKET_NAME') AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_LOCATION = 'static' STATIC_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION) STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage' While I have looked for problems, nothing looks out of the blue. Though running collectstatic still does it locally rather than uploading it to my S3 bucket. Is there a particular configuration I'm missing, or just something in general? I have the boto3 and storages installed. Django 2.0.3 Thanks. -

urlpatterns = [path('admin/', admin.site.urls),] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT) Please explain what is happening here in python.

use rest framework APIView to post item to cart
I have a use case of adding the items in a cart. In rest framework documentation, i saw an APIView where request.data is sent in the serialzer and checked if it is valid or not, if valid then return success response otherwise error. But without doing calculation like if item is present in the session or not how it gonna store the item to the cart table. I drew the logic(which I am totally unsure but has tried) but i could not align it in a rest framework way(APIView). Here is what I tried. class CartAPI(APIView): serializer_class = serializers.CartSerializer def get(self, request, format=None): reply = {} try: carts = Cart.objects.all() reply['data'] = self.serializer_class(carts, many=True).data except Cart.DoesNotExist: reply['data'] = [] return Response(reply, status.HTTP_200_OK) def post(self, request, format=None): reply = {} cart = Cart(request) product_id = request.data.get('product', None) quantity = request.data.get('quantity', None) try: product = Variation.objects.get(id=product_id) except Variation.DoesNotExist: pass isProductInCart = False for cart_item in cart: if cart_item.item.id == product.id: cart_item.quantity = quantity isProductInCart = True if not isProductInCart: # create and save new item in the cart cart_product = CartItem.objects.create(cart=cart) cart_product.item = product cart_product.quantity = quantity cart_product.save() reply['data'] = self.serializer_class(cart_product, data=request.data) return Response(reply, status.HTTP_200_OK) class Cart(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, …
