How to query a relationship that spans three models in Django?
I have the following models: class Station(models.Model): name = models.CharField(max_length=166) number = models.CharField(max_length=2) class Exercise(models.Model): exercice = models.CharField(max_length=166) series = models.CharField(max_length=2) reps = models.CharField(max_length=2) station = models.ForeignKey(Station) class Workout(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE) day = models.CharField(max_length=1, verbose_name="Dia") exercises = models.ManyToManyField(Exercise) I then created a table that presents the exercises for each workout using the following view: def planodet(request, id): plan = Workout.objects.get(id=id) exercises = plan.exercises.values() But when I loop through exercises I can't fetch the Station name. How can I access this? I've tried Station.objects.filter(name=exercises[0]) But to no success. -

How to get both pk and a form input on submit in Django
Am using Django to create a system that records available stock of a shop, and records the sales made. I have a 'Sell Item' button on every available item, so that the seller uses the button to record that a sale was made. So am requesting the pk(through the url) of the item on which the button was clicked(to know which item is being sold), and I also have a form where the seller will input the quantity being sold, so that I get how many items are being sold(Am trying to get this using the GET method). But am getting errors that quantity is None since am unable to get the quantity. This is my template: <td> <form action="{% url 'stock:sell' pk=item.pk%}" method="GET"> <input type="number" id="quantity" value="1" size="5"> {% csrf_token %} <button type="submit" name="submit">Sell</button> </form> </td> This is my url: path('sell/<pk>/', sell, name='sell'), And this is my views: def sell(request, pk): if request.method == 'GET': quantity_sold = request.GET.get('quantity') item = Item.objects.get(id=pk) if quantity_sold > int(item.quantity): messages.danger(request, "Not enough stock to sell that quantity!") else: item.quantity -= quantity item.save() return HttpResponseRedirect(reverse('stock:show_stock')) Am getting the quantity to make sure that only available quantity can be sold, and then to update to … -

Sending Javascript fetch to Django
I am struggling to send fetched json to Django, not sure if I am doing it in the correct way. I am trying to fetch API response with GET, then inside the fetch send each element to Django with POST, to populate my database (views and everything are already set up). API search request provides multiple Json responses, so I am trying to loop it. My code is as following: s_button.addEventListener('click', function(e){ var x = document.querySelector('#search'); var searching = "&search=" + x.value // fetches by search fetch(website + searching, requestOptions) .then(response => response.json()) .then(result => { var list = result; for (let i = 1; i < 10; i++) { console.log(result.results[i].name) //here it changes table based on id from html htmlname = "number" + i.toString(); // sets name to fetched name and id to fetched id document.getElementsByClassName(htmlname)[0].innerHTML = result.results[i].name; document.getElementsByClassName(htmlname)[0].id = result.results[i].id; console.log("REQUEST:") //this suppose to send to POST but it gives error! $(document).ready(function() { $.ajax({ method: 'POST', url: '', data: {'yourJavaScriptArrayKey': result.results[i], 'csrfmiddlewaretoken': '{{ csrf_token }}'}, 'dataType': 'json', success: function (data) { //this gets called when server returns an OK response console.log("it worked!"); }, error: function (data) { console.log("it didnt work"); } }); }); } id = result.results[0] }) … -

How do I get "the least frequent" item on a table by filtering with data from another table

This is what I've got so far: class SentenceViewSet(viewsets.ModelViewSet): serializer_class = SentenceSerializer permission_classes = (permissions.IsAuthenticatedOrReadOnly,) def get_queryset(self): queryset = Sentence.objects.all() state = self.request.query_params.get("state", None) if state is not None: # Get all records for this state records = Record.objects.filter( speaker__birth_city__state__abbreviation=state ) # Get sentence with the lowest number of records queryset = queryset.filter( id=records.values("sentence") .annotate(dcount=Count("id")) .order_by("dcount")[0]["sentence"] ) else: queryset = queryset.order_by("text") return queryset Unfortunately, this will only return sentences I have already recorded.

Upgrade PostgreSQL from version 9.6 to version 11 using Django 1.11 and Heroku
I have a monolithic application using Django 1.11 and Postgres 9.6 deployed on Heroku, I'm using Heroku Postgres Instances. Heroku is asking to upgrade to newer versions because Postgres 9.6 will be deprecated soon. I've tried 2 times to upgrade my production DB to version 10 and 11 and after deployed and connected to my application everything start going bad. Almost all query plans are taking a lot of time compared to the same plans in version 9.6, which is currently working very well. I've notices some errors due to pgbouncer connection after deployed with the new upgraded DB. pgbouncer cannot connect to serverSSL connection has been closed unexpectedly I'm using pgbouncer to handle DB connections on my application and also I'm using Heroku connection pool technology to deal connections on Postgres server too.I can see the detachment of the old pool and the attachment of the new one and seems to be working fine. Also, I've seen a bunch of SET operations taking almost 30 secs, not sure if it's just because everything starts to go so bad after the upgrade. Also even query plans with 1 step of INDEX call is taking almost 600 secs in a low … -

Create Django Serializer with default fields in Meta and query params

What python http server to use?
I'm looking to build a python script that will listen to requests on mysite.com/@username then will get the username and internally fetch this user's pictures from instagram, then do some processing on the images, save them locally so they don't have to be fetched again and return the urls of these new processed images. I have a basic idea of how to do it but I'm not sure if I should use something like Django, Flask or just simply http-server. This is something only I'll use so that's why I wonder if I might be overthinking it.
