startapp | Simple boilerplate ready for development bowtie | REST library

I created a django project, set up a virtual environment, and added django with poetry add.

inside pyproject.toml:

Im learning programming and im completely new in it..i was working on a project and i have used django for back-end. Now the problem im currenctly facing is that i got no idea how should i link frontend and backend ?.. first we created backend (where there is login/signup/and dashboard) using django and boostrap,js .. and the backend work perfectly so below the folder structure of the backend we are working on.

so this is the structure of the backend .. to be more clear check 2nd image.

Here you can see that, budgetwebsite folder which is just below the folder authentication. budgetwebsite is our main thing or a part of our system..

then we did django startapp for authentication(for username validation and email)

then we did django startapp for userincome(here we worked on userincome like add/delete income)

then we did django startapp for expenses(here we worked on expenses like add/delete/expense)

and that userpreference is our admin panel.

thats for the backend section

Now lets move on the front end section aswell.

then we created a different folder name front end and we started working on it.

So now lets move to the problem... i just want to merge this front end and back end ..

below is my code of setting.py

I created a new django app and ran it using python manage.py runserver . It ran normal and I could see the default page

With the shell outputting:

I am trying to fetch public holiday data for France, Australia and Germany from https://date.nager.at/ with the documentation at https://date.nager.at/swagger/index.html and store it in a JSON file.

Until now, I have created an endpoint /fetch_and_save with its own URL, but only managed to write dummy data in the views.py file. How do I fetch the data above and store it in a database through Django?

Edit: I have been asked to show the code. I ran

Running the code below i get "Realm accessed from incorrect thread." error on the second try! realm.write({ line , the first write line causes no error. Any idea on how to fix it?

New to Django and have just started building out a new project following a tutorial.

I have created a virtual environment as follows:

pip install virtualenv

virtualenv myproject_3_7_3

I then activate the virtual env and install Django as follows:

cd myproject_3_7_3

source bin/activate

pip install django

This installs Django version 3.2.10 successfully, so then I activate the project, add some folder structure and create an app using the following commands:

django-admin startproject myproject

cd myproject

mkdir apps

mkdir apps/core

python manage.py startapp core apps/core

I then open VSCode and I can see the project and all of the default folders/files there.

To start the app I run:

python manage.py startapp core apps/core

But I immediately get the following error in the terminal.

I'm a beginner in all these http and tcp/ip thing. So there maybe many things in these questions that may not make sense or are totally incorrect.

First I will add all the questions I had in mind since, I could not put them on title.

I work on django (python framework) for web development.

I'm confused as to how servers work. And how is the destination port is decided through the url?

MAIN Q : What I have learned so far is that through DNS we get the ip address of the website. And port (Both destination and source) are decided by the TCP. And sent through TCP headers. But how does it decide which port should it go to in a server(i.e. destination port).

MY ANS TO ABOVE QUESTION : After spending lots of my time, I have come to know that, http requests default to 80 and https defaults to 443 and similarly other types of requests also defaults to some port. So we can figure out the ip address based on this.

But this rises another question in my mind.

Another Question : I have also built a simple django website and deployed it on pythonanywhere. But I deployed it as a whole application. Suppose my django application accepts different types of requests like HTTP, HTTPS, SMTP, etc. Then how will the port for these specific tasks be decided? Because all these requests will come under single application, so they should run on the same port. I don't think the server will change anything in the application itself. So how will the destination port now be decided?

NOTE : I'm not sure if it is possible to make an application in django which accepts different types of requests. But it should be possible because we can create different app - with startapp and run on different url.

Where ever I read, it said that the default port for http is 80, then that means it should also be possible to change it?

MOST IMPORTANT QUES AND TO SUMMARIZE ALL DOUBTS Suppose I have a project which accepts different requests. And I want to deploy it on server then how will http requests and smtp requests are separated? Do I have to manually make different apps and then deploy on different ports or something? If not and everything runs on same port, then how is this port decided in the browser? Suppose my domain name is xyz.com then how will the specific port be accessed on the server?

Basically how is a destination port decided?

I I'm writing a code for weather application, with only two screens. And I'm using openWeatherApi to fetch weather data using http protocol from json file which is present on internet, to my weather UI. Now the the issue is that,the data from json is coming perfectly to terminal,but It does not come to UI screen until I press ctrl+s.The UI does not updates until I press ctl+S. When I run the code first time It does not show the current weather status(which is in Celsius degree),it just shows null, a written null on the screen,where current weather should be shown, and also the image behaves like that as well. Now I'm not getting is a setstate() issue or else. I don't know why the UI is not updating.I'm providing every file that I'm using. Please Help!.
