How to display object info only if model boolean is true
I'm working on a site that allows book submissions/suggestions. Anyone can submit book suggestions via a form on the site. However, I only want to display books on my index.html page that are approved by an admin. I have three boolean options in my models.py: Needs Attention Approved Rejected Needs Attention is checked by default. This lets admins know no one has addressed this submission. Once an admin addresses the submission they can uncheck Needs Attention and then check Approved or Rejected. In my index.html how can I display ONLY submissions that are checked Approved (via the Approved boolean)? -

How to pass context when testing deletion of an instance?
I've got a couple models, Car and CertifyRequest. When a Car instance is created, modified or deleted I need to create a CertifyRequest, which in turn needs to be manually approved. The CertifyRequest instance contains the time it was created. I've tested creating and modifying by injecting context={"now": …} into a CarSerializer instance, but I can't figure out how to do the equivalent when deleting: Delete requests are never passed to the serializer, so I can't access the context in the same way. I can override destroy in the ModelViewSet and use get_serializer_context within it, but I can't seem to pass the serializer to the ModelViewSet instance. I do not want to use a horrible hack like an optional query parameter. -
Cannot access ManyToManyField with through attribute on Django template
Here is a snippet for my ManyToManyField with through attribute models. I'm trying to access a stores's sponsored_stores on Django template, but it doesn't work. I've already tried Store.objects.first().sponsored_stores.all() in Django shell, and it returns a list of sponsored stores. So, I went to Django template to get the sponsored stores on a template file and I tried {{ store.sponsored_stores.all }}, however it returns an empty queryset. Did I put a wrong command on the template level? models.py class Store(TimeStampedModel): sponsored_stores = models.ManyToManyField( 'self', through='Sponsorship', symmetrical=False, related_name='sponsored_store_of_store') class Sponsorship(TimeStampedModel): sponsor_giver = models.ForeignKey(Store, related_name='sponsor_giver', on_delete=models.CASCADE) sponsor_receiver = models.ForeignKey(Store, related_name='sponsor_receiver', on_delete=models.CASCADE) score = models.IntegerField(default=0) class Meta: ordering = ('-score', ) -
Can I take a parameter from the url and use it in a class based view to set field on a form
I am creating a form in my django app. My app has a user, a user can have many transactions and a transaction can have many sales. I'm trying to create a form to add sales to the DB. I'm trying to pass a parameter in the URL (transaction_id) and use it in the Django class-based view CreateView to set the corresponding (foreign key) field in the form. Is it possible to do this and if so how could I apply it. Class based create view below class SaleCreateView(CreateView): model = Sale fields = ['amount_sold', 'total_price_sold', 'note'] def form_valid(self, form): URL below path('sale/new/<int:pk>', SaleCreateView.as_view(), name='sale-create'), Link below {% url 'sale-create' transaction.id %} Sale form below <div> <form method="POST"> {% csrf_token %} <fieldset class ="form-group"> <legend class="border-bottom mb-4">Enter Sale</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class ="btn btn-outline-info" type="submit">Enter</button> </div> </form> </div> -

How do I insert a javascript variable into a model in Django?
I'm trying to save the longitude and latitude of a user to a model to use with various API's for things like traffic and weather and what not. I get the users latitude and longitude by using the navigator.geolocation that is in html5. What is the best way to save this info to a UserProfile model? I've tried setting up a form to use but can't get anything to work with the check box I have that enables geolocation. I've also thought of using ajax but don't know how to pass the data to the model in django. <script type="text/javascript"> $(document).ready(function(){ $('input[type="checkbox"]').click(function(){ if($(this).prop("checked") == true){ getLocation() } else if($(this).prop("checked") == false){ console.log("Location services are disabled"); } }); }); function getLocation() { if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(showPosition); } else { console.log("Geolocation is not supported by this browser."); } } function showPosition(position) { console.log("Latitude: " + position.coords.latitude + " Longitude: " + position.coords.longitude); var latlon = (position.coords.latitude + ','+ position.coords.longitude) console.log(latlon) }; This is what I'm using to get the location of the user, it's in a profile.html page I have set up for the user.

How to access through model in django
I'm trying to manage sponsored stores of each store. There is sponsored_stores field in Store model and it has through attribute to connect the field to Sponsorship model. I need it to be done since I need score field between a sponsor store and a sponsored store. models.py class Store(models.Model): sponsored_stores = models.ManyToManyField( 'self', related_name='sponsored_stores_of_store', blank=True, through='Sponsorship', symmetrical=False) class Sponsorship(TimeStampedModel): sponsor_giver = models.ForeignKey(Store, related_name='sponsor_giver', on_delete=models.CASCADE) sponsor_receiver = models.ForeignKey(Store, related_name='sponsor_receiver', on_delete=models.CASCADE) score = models.IntegerField(default=0) I'm trying to access score field through sponsored_stores, so I tried something like store.sponsored_stores.sponsorship.score. I know it's not working, but I can't figure out how I can access score field from sposored_stores. -
Handle POST request query param from browsable API in Django Rest Framework
I have a requirement of having a query param in a POST request with the JSON payload in the body. Now in django-rest-framework I have been able to do that by overriding the perform_create method of ModelViewSet in my view class, but what I can do to have it appear in browsable API. I tried django-filter and its backend but they are geared towards filtering(obviously) in a GET request. I don't want to filter but want to just use that query param as a parameter to run celery tasks during perform_create. This is how my viewset looks right now. Don't worry about the run_flow method its selinon thing that I am using, it will run celery tasks based on my flow. class AbcViewSet(viewsets.ModelViewSet): queryset = Abc.objects.all() serializer_class = AbcSerializer filterset_fields = ('fk_field', ) def perform_create(self, serializer): query_param1 = self.kwargs.get(self.request.query_params.get('param', None)) ...schedule salary using the query_param1 and save the model... my request for this will be like http://127.0.0.1:8000/abc/?param=xyz If you notice above I want to be able to fill thatparam using browsable API. Trying to search I have a feeling it will involve creating some kind of HTML view rendering for the param but If its more easier available from browsable … -

Is it even possible what I'm trying to do with Django?
I'm setting up a Heroku site to deploy a Django app for a school project. The problem is with static files using whitenoise in Django. Quick context: My app consists of a form that takes 4 values that I use for quick math calculation inside a script. The aim of this script is to perform the calculations, draw a plot using matplotlib and save it in the static folder of my django app replacing the old one if it already exists. This static file is used to display in a html page on the site. Locally It works like a charm updating the plot each time I submit a new form. But when I try on Heroku it throws an "[Errno 2] No such file or directory: '/Users/jeff/Desktop/trydjango/src/static/yield_curve.png'" when I submit the form. Here's the settings.py I have concerning static files: STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'),] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' My directory look like this : src |-- /TER |-- -- /settings.py |-- /graph |-- /static/... |-- /staticfiles/... |-- /manage.py I would like for my site to refresh the image each time I submit a form using the new 'yield_curve.png' I saved in the static … -

So my question is: How do I ensure that my django app is running on python 3 and Django 2.2? Do I have to start gunicorn differently? In case readers haven't used Digital Oceans "one-click Django droplet" : It utilizes gunicorn, NGINX, and ubuntu. Thank you! ` -

Django Tutorial Part 1: incorrect path causing (404)
I have setup part 1 of the django tutorial and am receiving the following error when trying to access the polls app:[HTTP Error Message] I'm using Django 2.2, Python 3.7, Apache 2.4.6, mod-wsgi 4.6.5. I was able to complete the tutorial using the built in web server, but I started running into problems when I added Apache and mod-wsgi into the mix. Here is my code: proto/urls.py: from django.contrib import admin from django.urls import include, path urlpatterns = [ path('polls/', include('polls.urls')), path('admin/', admin.site.urls), ] polls/urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), ] polls/urls.py from django.http import HttpResponse def index(request): return HttpResponse("Hello, world. You're at the polls index.") The only thing changed in the settings.py was the TIMEZONE. Everything else is set to defaults. Something seems to be up with the urls and path matching. The url I used (proto.slc.venturedata.com/polls/) should match the 'polls/' path, but the error message says that the path is empty. In experimenting I found that I didn't receive an error if I modified proto/urls.py by replacing the 'polls/' path with an empty path: ''. urlpatterns = [ path('', include('polls.urls')), path('admin/', admin.site.urls), ] Am I missing something? -
(nginx + gunicorn) small server instance drops/timeouts connections on +60 simple API requests / second. Can it be improved?
I'm setting up the first production architecture for my Django-based app. I'm using nginx + gunicorn + remote postgres database setup. After performing simple API load tests with https://loader.io I've found out that when increasing the number of clients sending api requests over 60 clients/second for 30 seconds-long test the tool shows errors that the connections timeout. When using double server setup with a load balancer I can double the clients/second number but I would expect a single 3vCPU /1 GB ram setup to be able to handle more than 30 requests/second - am I right? I've tried a lot of differente gunicorn / nginx config parameters but nothing seems to help. This is the content of my /etc/nginx/nginx.conf file: user www-data; worker_processes auto; pid /run/nginx.pid; worker_rlimit_nofile 100000; events { worker_connections 4000; multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; server_names_hash_bucket_size 512; include /etc/nginx/mime.types; default_type application/octet-stream; ## # SSL Settings ## ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE ssl_prefer_server_ciphers on; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; gzip_vary on; gzip_types text/plain text/css application/json …
