Django: request.GET.get('x') does not fetch selected item in dropdown. Error: None
I have the combobox countries (def trip_selector) dependent on the combobox trips (def trips). In the comboboxes I display the item correctly. If I click on the button I would like to print the selected item in the textarea (def result). The problem is that I can't extract the selected item in the trips combobox, I get the error: None. I use selected = request.GET.get('trips') also because trips is the name in select name="trips" id="id_trip" in the trips.html page. The selected item to print does not send data, it only displays it. I can't figure out why it doesn't work. Can you help me please? IMPORTANT: i specify one important thing in case you want to help me: I don't want to move selected = request.GET.get('trips') inside the def test1() function or inside the def result() function, at most create another function if necessary. def test1 is just one of many functions I'm going to create, so it's pointless to move selected = request.GET.get('trips') into each function test1, test2, test3, test4, etc. These functions will be displayed in textarea (def result) which must remain only a viewer because it will display various functions (and not just one). views.py from django.shortcuts … -
Dynamic filtering on the FastAPI site
I need to implement filtering on the site, I use MongoDB. The thing is, I have multiple arrays. old_fliters, where you use different values of all filters, there are arrays of filters, where available filters should be available, when I had only two age and brand filters, then the following logic worked if brand and age were selected: in the catalog by brand announcement and age in the catalog by brand announcement or age when the filters became more than two of these, the logic stopped working, please help solve a specific problem, what kind of logic should be used, but massive filters are presented in bold (available for selection), the old_fliters array for comparison with filters, that is, what is not in the filters array, but is in the old_fliters array on the frontend is obscured. Here is a good example: I choose a material from cardboard, the country is China, and with such logic as above, the age remains 0+, which either China or cardboard has, but if you cross all three filters, there are no such products. from math import ceil from fastapi import HTTPException, APIRouter, Query route_catalog_test = APIRouter() from database import my_collection from enum import … -
Is it possible to disable datatables' default custom search builder draw?
My Django webapp uses datatables with serverside processing and custom search builder. I am trying to change the URL to include the query parameters from the searchbuilder for bookmarking purposes. Using the ajaxSucesss settings.url object and the HTML history.pushState method, I can get the necessary parameters and append them to the URL. The issue is, each time an ajax request is made, datatabels adds a "&&" followed by a deafault draw to the request. Is there a way to disable the default datatables draw? In the Django html template: $( document ).on( "ajaxSuccess", function( event, xhr, settings ) { // collect everything in the URL after the "?" draw_string = settings.url.split("dt-json/?")[1] // split the original URL at the "&&" and keep only the first half. // the second half is the default dt draw let query_string = draw_string.split("&&")[0] // if the datatable is filtered. if (draw_string.split('&&').length === 2 && !draw_string.split('&&')[1].includes("draw=1&")) { // replace the string with the second draw query_string = draw_string.split('&&')[1]; } url_params = "/?" + query_string // and replace the URL with the new URL without reloading the page. history.pushState(null, "", url_params) } ); In views, to to process the ajax request: def query_string_to_dict(query_string_arg): # When adding params … -
No backend data is publishing from fullcalendar in Django
I am attempting to use the fullcalendar package with Django for calendar implementation. I am able to display the calendar, create and save a model to the database, but I am having issues bringing it into the template. I can bring in context event information, as for bringing it onto the actual calendar, I am missing the target and hitting a wall. My belief is how I am calling on the URL to bring back the JSON response data. All assistance is appreciated models.py class CalendarEvents(models.Model): id = models.AutoField(primary_key=True) type = models.CharField(max_length=50, choices=EVENT_CHOICES) name = models.CharField(max_length=145,null=True, blank=True) location = models.CharField(max_length=100, null=True, blank=True) start = models.DateTimeField(null=True, blank=True) end = models.DateTimeField(null=True, blank=True) urls.py path("calendar", view=apps_calendar_view, name="calendar"), path('calendar/all_events/', view=apps_calendar_all_events, name='calendar.all_events'), views.py def apps_calendar_view(request): all_events = CalendarEvents.objects.all() context = { "events":all_events, } return render(request,'apps/apps-calendar.html', context) def apps_calendar_all_events(request): all_events = CalendarEvents.objects.all() out = [] for event in all_events: out.append({ 'type':event.type, 'title': event.name, 'location':event.location, 'id': event.id, 'start': event.start.strftime("%m/%d/%Y, %H:%M:%S"), 'end': event.end.strftime("%m/%d/%Y, %H:%M:%S"), }) print(out) return JsonResponse(out, safe=False) apps-calendar.html <div class="col-xl-9"> <div class="card card-h-100"> <div class="card-body"> <div id="calendar"> </div> </div> </div> </div> <script> import { Calendar } from '@fullcalendar/core' import dayGridPlugin from '@fullcalendar/daygrid' const calendarEl = document.getElementById('calendar') const calendar = new Calendar(calendarEl, { plugins: [ dayGridPlugin // … -
Django intermediate many-to-many model
I wonder if I can create intermediate model for many-to-many field without specifying related_name but rather just put ManyToManyField on both Models. I was watching some tutorial on Django ORM and instructor explicitly said we can't use ManyToManyField on both Models (while I think that is true if Django creates own table, I am not sure if it is if we specify custom intermediate model). So this is the code: class Category(models.Model): products = models.ManyToManyField("Product", through="CategoryProduct") name = models.CharField(max_length=255, unique=True) class CategoryProduct(models.Model): category = models.ForeignKey("Category", on_delete=models.CASCADE) product = models.ForeignKey("Product", on_delete=models.CASCADE) class Meta: unique_together = ("category", "product",) class Product(models.Model): categories = models.ManyToManyField("Category", through="CategoryProduct") attribute_value = models.ManyToManyField("AttributeValue", related_name="products") name = models.CharField(max_length=255, unique=True) I tested it with dummy data and this code works for me: p = Product.objects.get(id=1) c = Category.objects.get(id=1) p.categories.add(1, 2, 3) c.products.add(1, 2, 3) -
Serialize list of a specific field of Many To Many relation in Django

Advanced Python Stopwatch
I'm thinking about creating an advanced stopwatch as a Python project. The way I want it to work is like this: Stopwatch Starts If stopwatch paused a "rest" stopwatch begins When stopwatch is started again initial stopwatch begins and the rest stopwatch is paused. This cycle continues until stopwatch time is ended. I haven't started writing this because I'm unsure of how it would work. I'm not sure how to manage the stopwatch times as they are pausing and starting. If it makes any difference I'm thinking of implementing this into a Django app. Thanks, Mitchell -

Django+Htmx: get the selected item of a combobox (created with Htmx) and print it?
I need to get the selected element of the combobox with function def trips. Then use it in the def result function which is used to print the selected item in textarea. The button request is only used to display the data (in the textarea). P.S: If you're wondering, the trip_selector function is that of the first combobox that is dependent. views.py def trip_selector(request): countries = Trip.objects.values_list('country', flat=True).distinct() trips = [] # no trips to start with return render(request, 'form.html', {"countries": countries, "trips": trips}) def trips(request): country = request.GET.get('country') trips = Trip.objects.filter(country=country) return render(request, 'trips.html', {"trips": trips}) def result(request): test_print_in_result = trips return render(request,"result.html", {"test_print_in_result": test_print_in_result}) In the other files everything is ok, I need help only in views.py UPDATE form.py {% extends 'base.html' %} {% block content %} <!-- First Combobox --> <label for="id_country">Country</label> <select name="country" id="id_country" hx-get="{% url 'trips' %}" hx-swap="outerHTML" hx-target="#id_trip" hx-indicator=".htmx-indicator" hx-trigger="change"> <option value="">Please select a country</option> {% for country in countries %} <option value="{{ country }}">{{ country }}</option> {% endfor %} </select> <!-- Second Combobox ???????

I am creating a project using several things : psycopg2 to query a SQL database pandas to model the data bokeh to create graphics django for the back-end bootstrap for the front-end I'm discovering the front-end, using the system of links in or tags to retrieve the CSS and JS elements needed to make bootstram work, as indicated on the offical website.
