Slow spatial join on a single table with PostGIS
My goal is to calculate if a building have at least one shared wall with a building of another estate. I used a PostGIS query to do so but it is really slow. I have tweaked this for two weeks with some success but no breakthrough. I have two tables: Estate (a piece of land) CREATE TABLE IF NOT EXISTS public.front_estate ( id integer NOT NULL DEFAULT nextval('front_estate_id_seq'::regclass), perimeter geometry(Polygon,4326), CONSTRAINT front_estate_pkey PRIMARY KEY (id), ) CREATE INDEX IF NOT EXISTS front_estate_perimeter_idx ON public.front_estate USING spgist (perimeter); Building CREATE TABLE IF NOT EXISTS public.front_building ( id integer NOT NULL DEFAULT nextval('front_building_id_seq'::regclass), type character varying(255) COLLATE pg_catalog."default", footprint integer, polygon geometry(Polygon,4326), shared_wall integer, CONSTRAINT front_building_pkey PRIMARY KEY (id) ) CREATE INDEX IF NOT EXISTS front_building_polygon_idx ON public.front_building USING spgist (polygon) TABLESPACE pg_default; CREATE INDEX IF NOT EXISTS front_building_type_124fcf82 ON public.front_building USING btree (type COLLATE pg_catalog."default" ASC NULLS LAST) TABLESPACE pg_default; CREATE INDEX IF NOT EXISTS front_building_type_124fcf82_like ON public.front_building USING btree (type COLLATE pg_catalog."default" varchar_pattern_ops ASC NULLS LAST) TABLESPACE pg_default; The m2m relation: CREATE TABLE IF NOT EXISTS public.front_estate_buildings ( id integer NOT NULL DEFAULT nextval('front_estate_buildings_id_seq'::regclass), estate_id integer NOT NULL, building_id integer NOT NULL, CONSTRAINT front_estate_buildings_pkey PRIMARY KEY (id), CONSTRAINT front_estate_buildings_estate_id_building_id_863b3358_uniq UNIQUE … -
Authorization: Any Benefit of OAuth2 for First-Party Web and Mobile Clients
I would like to know whether there is any security benefit to using OAuth2 for authorization where all clients are developed, owned and controlled by the API developer/owner/controller; as opposed to using token authentication per Django Rest Framework's Token Authentication. My understanding OAuth is that it was created for the purpose of delegated authorization - allowing third party applications access to your user's data without knowing the user's credentials. It seems to now have become a standard, even where delegation is not required. I do not understand why. Is there any benefit at all where delegation is not required? My setup will be a Django Rest Framework API with a web SPA client and mobile clients. Permissions are associated with user accounts. Users login with email and password. I do not think that this is an opinion question, because I'm not asking which is better, I will make that decision myself, I'm just trying to understand whether there is actually any security benefit at all to the OAuth option. This question might be somewhat open-ended but hopefully is within an acceptable margin since I'm restricting the considerations to security considerations. Developer effort etc are not necessary to discuss. -
Django form for user input to database
I am attempting to have a form which users can create new orders. The user gives the order a name, submits the form and then auto populates the creation date and user who created it. Additionally, I want the form to be on the same page as the contents of the database, so that a list of all orders can be displayed underneath. When the form is submitted, the page should refresh to show the new entry. I need a bit of help tying all this together. At the moment, I am not getting the form displayed on the site for the users to fill in. models.py from django.db import models from django.contrib.auth.models import User from django.forms import ModelForm class Order(models.Model): order_name = models.CharField(max_length=100, unique=True, null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, related_name='Project_created_by', on_delete=models.DO_NOTHING) def __str__(self): return self.order_name class Ce_Base(models.Model): ce_hostname = models.CharField(max_length=15) new = models.BooleanField() location = models.TextField() order_reference = models.ManyToManyField(Order) class OrderForm(ModelForm): class Meta: model = Order fields = ['order_name'] views.py from django.shortcuts import render from django.contrib.auth.decorators import login_required from .models import Order from .models import Ce_Base from .forms import OrderForm @login_required def home(request): context = { 'order': Order.objects.all() } return render(request, 'orchestration/order_create.html', context) @login_required def orderprocessing(request): … -

Django & Ajax - "Like" button, how to make it work for mutliple posts on a page?

Whats a good pattern for a web-application for serving files?
I am working on an angular Web-Application where it's possible to view pdf-files in a pdf-viewer in the browser. The Web-Application is also consuming a REST-Service in Django. In the Database the information of the pdf-files is stored. The Web-App is calling the REST-API to check where the files are stored. As I am still in the Proof-Of-Concept Phase of the project, the PDF-Files are currently stored in the assets folder of the angular web, which of course is not what I want in the end. When the Files or the Directories change, the Database should be updated automatically (or via a trigger in the app). I have two questions: Is there an obvious way to serve the files in this combination? i.e. an apache server? I imagine there are built in solutions in dedicated file servers to detect changes of the watched directory. For a partly solution would it be reasonable to write a script on the django site, which does the file-serving, the updating and also providing the REST-API? -
Django: form not showing up in rendered template

How to access one Django Project Database from another Django Project?
I am trying to access one Django Project Database value from another Django Project. So far I have tried making REST API on both the applications and it is working somewhat well on the local server. However, I am concerned that when I will be deploying both the projects on the server it will create some lag to access over the API. Moreover, if one server/application is down for maintenance, the other will be inaccessible. Is it possible to directly access the other app database without using API as it will be much more faster and reliable? Thanks. -

Using Django ORM to sum annotated queries
I am using Django in combination with a TimescaleDB to process energy data from pv installations. Now I would like to calculate, how much energy multiple plants have generated within a given timebucket (usually per day). The plants writing the new values in a table which looks like that: customer datasource value timestamp 1 1 1 01.05.22 10:00 1 1 5 01.05.22 18:00 1 2 3 01.05.22 09:00 1 2 9 01.05.22 17:00 1 1 5 02.05.22 10:00 1 1 12 02.05.22 18:00 1 2 9 02.05.22 09:00 1 2 16 02.05.22 17:00 Now what I would like to have is, get the overal daily gain of values (so, for each day: Last Entry Value - (minus) First Entry Value) for each customer (which means, sum the daily generated energy values from all datasource which belong to the customer). In the above example that would be for customer 1: Day 01.05.22: Daily Gain of Datasource 1: 5 - 1 = 4 Daily Gain of Datasource 2: 9 - 3 = 6 Overall: 4 + 6 = 10 Day 02.05.22: Daily Gain of Datasource 1: 12 - 5 = 7 Daily Gain of Datasource 2: 16 - 9 = 7 Overall: …
