SAVE CHECKED STATE OF CHECKBOX AFTER CLOSING THE WEBSITE
I'm working on a django project in which i have a list of checkboxes. I'd like to know how do i save the fact that the checkbox has been checked after i close the website? the checkbox's label are the values of a Model that i created. As database i'm using the default one given by django, sqlite3. here's a little snippet of my code: <ul class="list-group list-group-flush"> <div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckDefault"> <label class="form-check-label" for="flexCheckDefault"> {{project.description}} </label> .... </ul> -
Make, migrate model programmatically, and reload / repopulate django application's new settings / configurations
I am making a model programmatically using the following code: modelObj = type(m.get("name"), (models.Model,), m.get("attrs")) After that I am trying to run the makemigrations, migrate, and autoreload command using the following code. def migrate_and_reload(): management.call_command("makemigrations") lm = MigrationRecorder.Migration.objects.filter(app=modelObject._meta.app_label).last() management.call_command("migrate", modelObject._meta.app_label, lm.__dict__.get("name"), "--database==test") from django.utils import autoreload autoreload.restart_with_reloader() But: And, get the Message from autoreloader that the server port is already use If I comment the autoreloader then Migration is not run into the database. However, Makemigration works and a migration file is created in the app's migration folder) My basic goal is to register the dynamic model programmatically, make respective migrations (handle any errors if there), migrate it to Db, and reload the server I will prefer not to reload the server, but seems like I have no other options to reload all the settings or populate the configurations in Django 3.0.3. Any help is welcome -
Django use rowspan in DataTables

DJANGO datetime wrong on template even after timezone setup

Django map model data to external data
I want to map data from the https://developer.microsoft.com/en-us/graph/graph-explorer api as a data source to have the additional required data on the model.

I could not find anything on this topic, besides maybe abusing the from_db() method as an override, if this even works. TLDR; I want data from an external API on my local model -

Facial Recognition using django
I am using django to access client webcam so that facial recognition process can be done. Right now I am using django channels to transfer the frame to the server and then return the annotated frame back to the same page. const FPS = 3; chatSocket.onopen = () => { console.log(`Connected to socket`); setInterval(() => { chatSocket.send(JSON.stringify({ 'message': getFrame() })); }, 1000 / FPS); } this message is then decoded and converted to a frame so as to use Opencv and facial detection, once the predictions are made, the data is returned back to the same page using the same websocket. This process is working fine, but the final page lags way too much , is there any other option to transfer the data in real-time? -
