Django angular database integration - javascript

I have a django project that uses postgresql. I am trying to use angular as a front end in my html pages. Which is the best approach to use the angular js controllers in the django project to connect to the django models and the database to perform basic operations like insert, delete, update etc?
Currently i just have static data that i defined in my angular controller. But i would like to know how to get the data from the database dynamically. Any advice will be helpful

As per my experience with Django and AngularJs, first you should make api in django to get the data from database. Afterthat, in single page application, you should make angularjs service for each api in controller. After rendering data, you can submit / modify your data either through api or through form submission(with form validation).

How to render a Django Serializer Template with React Js?

I've set up my api for a basic model in my Django project. I've defined my post and get methods and everything is working correctly. Now, I'm wondering how I can render my Django model using react js. Essentially, I'm wondering how I can use react js to assign my django model values that were inserted using reactjs instead of django. For example, if my django model's fields are "name" and "id", how can I assign these fields using reactjs instead of the basic Django page(I've inserted my current page below)? Do we need to use axios or jquery to make these transitions? Thanks.
Instead of thinking how to render your django model in react, i think it is easier to understand when you think in the server-client model.
Basically you want to get you data from your django server and then show it in the client, using react.
To do this with Django rest framework, the best way is to make HTTP requests from the client to the server. You could use the browser built-in fetch api from javascript or a http library like axios.

Live database fetch using Laravel and React

I'm new to React and still learning Laravel, and I was wondering how can I live fetch data from the database using the Laravel Controllers. I want to use React too but I really don't see his utility there.
From my searches, I found an Ajax method, but I really want to use just Laravel and React to do so. Is it possible?
Like displaying the new users directly from the database without refreshing the whole page? I'm using Mysql to manage my database.
First of all, You need to set up laravel sanctum to get the authenticated data.
But if you don't want the authenticated data. You can just use a fetching library like axios to fetch data from the laravel. You need to add the cors (which is localhost:3000) in app.cors.php file of laravel root directory.
But if you are using reacjs with laravel like with intertia.js (which I prefere btw), You don't need the cors, laravel will work out of the box....

How to store information from javascript into a Django model?

I currently have an app which uses HTML/CSS/JQuery. As of right now all my data is saved in Jquery (and therefore not saved between sessions), but I am learning Django and want to learn how I would save that JQuery data into Django models. So how do javascript and django communicate in order to save information from one to the other?

Pass a request to a DJANGO REST api using Angular and then return those results in a DJANGO view

Ok, so basically what is happening is I have a search input on my index page. The user types something in the search input, and that is sent to the Django REST api which returns the data in JSON format. I can loop through that results array using Angular ng-repeat. But my question is: is there a way to send that request to another django view and have django return the values using a for loop and a template that I already created?
( I am trying to avoid recreating the template specifically for Angular because that would be repetitive)
Any suggestions, or help on this comes much appreciated. Thank you in advance for taking the time to help me.
All the best.
It depends on the architecture of your application.
If you are building your client as a single page web application using Angular & your business logic is served using the Django REST API in JSON/XML format. Then rendering of the view should be the responsibility of the client side code.
As per me whatever you are doing looks perfectly okay. I don't see any redundancy of the templates in this architecture.

AJAX with Django in RESTful environment

I am new in restful programing. I have a django website, my goal is to load part of the website asynchronously.
By default what I do now is:
call a url (e.g. localhost:8080/index) -> Routes the Django view -> View takes data from database (mongodb if you are curious) -> View gets the template -> Render all together and send back to browser
What I want to improve is:
When I have opened a url e.g. localhost:8080/index and I trigger an event (e.g. click a <a>) to send a request to my database and load other data.
My question:
What is the step I have to do to bridge the javascript / ajax with my mongodb safely?
Additionally I am considering to use a front end MCV framework (I think about backbone/I have limited knowledge as well) to handle the front-end requests. E.g. localhost:8080/index#2 returns objects with id : 2 of my database.
You should look at the following rest API frameworks for django. They will help save you a lot of time.
Django Tastypie
Django Rest Framework
I have used both and personally like tastypie better. Once you have integrated one of these in your project you can use any front end javascript framework like angularjs or backbone or even not use one and simply make a call to the resource url to get the data via ajax.
