How to map Leaflet drawn objects (polygons, points etc.) to PostGIS entries?
I have a Leaflet map, Django project that uses it (template) and a PostGIS as DB. I am looking for a way to synchronize my Leaflet map with the underlying DB including support for loading, editing and deleting of DB entries directly in the web browser. Currently I have a single test table in the DB (beside the typical Django ones) that can be recreated using the following SQL script: CREATE TABLE public.test_pois ( id int8 NOT NULL GENERATED BY DEFAULT AS IDENTITY, geometry public.geometry(point, 4326) NOT NULL, prop_name varchar(128) NOT NULL, prop_description varchar(1024) NOT NULL, CONSTRAINT test_pois_pkey PRIMARY KEY (id) ); CREATE INDEX test_pois_geometry_1b8e72a8_id ON public.test_pois USING gist (geometry); The Model is as follows: from django.db import models import django.contrib.gis.db.models as gis_models class POI(gis_models.Model): geometry = gis_models.PointField() prop_name = models.CharField(max_length=128) prop_description = models.CharField(max_length=1024) class Meta: db_table = 'test_pois' Using map.on('pm:remove', (layer) => { console.log('Deleting action detected', layer); /* TODO Ajax DELETE request here */ }); in my template gave me an insight of what is passed around during the deletion procedure: layer: Object { _initHooksCalled: true, _popupHandlersAdded: true, _leaflet_id: 385, … } _eventParents: Object { 386: {…} } _events: Object { dragend: (1) […], click: (2) […], keypress: (1) … -
javascript fetch is fired double
I have a simple function in javascript that fetch and URL and update the HTML page when it got a response like: function post_db(self) { // other code here async function postData() { const url = "fetchnewseq" const response = await fetch(url, { method: 'POST', headers: { 'X-CSRFToken': csrftoken, 'Content-Type': 'application/json' }, body: JSON.stringify(comandi_json) }); return await response.json() } postData().then((data) => { window.location.replace(data.url); }); } The post_db function is fired by a button like <button onclick="post_db(this)" class="btn btn-success">Conferma</button> On the backend I'm using Django and the view that manages that URL is def fetch_new_seq(request): json_ricevuto = json.loads(request.body.decode("utf-8")) print(json_ricevuto) messages.success(request, "Ricevuto") redirect_url = reverse('newSeq') return JsonResponse({'url': redirect_url}) For some reason, the fetch is fired two times as I'm seeing the function on the backed with the same results two times I can't understand why it happens tho as, the button is clicked just one I'm also seeing on the console of Mozilla Browser I got the error Uncaught (in promise) TypeError: NetworkError when attempting to fetch resource. -
Django+DjangoRestFramework+React(TS): React-Image component showing my images' size as 1295x0
In Django; I have Group, Class, Model and Product as, well, models. These are in a hierarchy of Group{Class{Model{Product}}}. So I made dropdowns which works like: Group Checkbox |-Inner Classes of Selected Group |-Inner Models of Selected Class |-Inner Products of Selected Model (<Image> element here) The Product models has an image field, which is returned succesfully from the response.json. I can open the image files, e.g. http://localhost:8000/media/images/p1111.png. Its width is smaller than 1295px and its height is bigger than 0px, ofc. But in website it does not show. Then I open Chrome DevTools. Component is there, in component's source code <div>s and <img> are there, but image's size is shown as 1295x0. I open image url, it's smth like, 256x256. I can (of course) make image width 500x500 using CSS, but what if the use inputs an image with different image ratio and size? That will make it look worse or make the image show partially, so both possibilities are bad. So, can I solve it by changing the React part? Or I'm gonna write a function to Django part? index.tsx: import React from 'react'; import ReactDOM from 'react-dom/client'; import './index.css'; import App from './App'; import reportWebVitals from './reportWebVitals'; … -

Issue with generating access token in Django using Zendesk API

Can I configure both ElasticSearch and ChromaDB in a single django application?
I have read the documenations https://docs.djangoproject.com/en/4.2/topics/db/multi-db/ but this page https://django-elasticsearch-dsl.readthedocs.io/en/latest/ describes how to use ElasticSearch. That doesn't seem to allow multi db with elastic search. I was also not able to find the settings for ChromaDB. I am trying to build an application that can use LLM via langchain and chroma db, but I have a data source in JSON that I want to store in elastic search. I am hoping to find a solution to use both elastic search for some models and chromadb for other models and potentially mysql for other models. Currently I am thinking two or three instances of Django applications with a shared vue application accessing the REST interfaces corresponding to the models. I would have one instance of django to handle user login and management and SSO for the other(s) -

Exception handling in Django/DRF
I want to check for correctness of request.data whenever there would be a POST request to 127.0.0.1:8000/api/v1/events/ Currently, I do have Event model class Event(models.Model): title = models.CharField(max_length=50) description = models.CharField(max_length=250) price = models.IntegerField(default=0) created_by = models.ForeignKey(User, related_name='created_events', on_delete=models.CASCADE) guests = models.ManyToManyField(User, default=None, blank=True) categories = models.ManyToManyField('Category', default=None) event_type = models.CharField(choices=EventType.choices, max_length=10) created_time = models.DateTimeField(auto_now_add=True) updated_time = models.DateTimeField(auto_now=True) start_time = models.DateTimeField(auto_now=True) seats = models.IntegerField(default=0) I want to check if the user is submitted the required fields in the right format. Also, whenever there would be a PATCH request 127.0.0.1:8000/api/v1/events/{pk}. Then, updated_time, event_type should not be in the request.data (meaning that they should not be updated). How can I make sure that everything is correct in the request.data? It can be done by checking request_keys = request.data.keys() actual_keys = self.serializer_class().get_fields().keys() result = [x for x in request_keys if x not in actual_keys] if result: return Response({'error': 'Invalid data'}, status=400) But the problem is that, I do need to check for different fields whenever the request.method is different, like, POST and PATCH, .get_fields() will return just all the fields in serializer. However, for PATCH I should not have updated_time, event_type fields. Also, I need to make sure that all the request.data fields … -

DJANGO: combobox doesn't print in textarea

Template is not saving Image to database
I am developing a website that allows users to upload projects with various details such as name, description, image, and deadline. However, I am facing an issue where, upon clicking the "Save Project" button, i get redirected to the homepage, but the image does not get saved in the database while everything else does. No error message is displayed. The problem may lie in the form and script sections since it has been able to save image, but after making adjustments to the form and adding script code, to make it look nicer, it stopped working.

Django: Problem with urlpatterns for a page after login
After login, i can't access the redirect page (home.html). The page is not found, because I misspelled the urlpatterns of the home page. I'm new to Django. In urlpatterns work fine correctly: index page, login page and logout page. But the home page doesn't. I believe the problem is the urlpatterns of the home. The page is located at templates/app1/home.html Project/urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('app1.urls')) App/urls.py from django.urls import path, include from . import views from app1.views import index from app1 import views urlpatterns = [ path('', index, name='index'), path('login/', views.sign_in, name='login'), path('logout/', views.sign_out, name='logout'), path('home/', views, name='home'), #ERROR HERE??? ] In views.py I don't have any home related functions. I only have the login/logout functions working correctly. How can I display the home correctly?
