What is used where and how in Django 2022?
!Complete Beginner! I went into Django with the background of building Sass web apps. CSS, HTML, Django and you have something working, I thought. After some weeks now you also have the basics, but there you quickly reach your limits if you want to create "useful/modern" web apps Today I was thrown off with terms like "Ajax XMLHttpRequest needed" "django without javascript does not work" htmx? or javascript? Or both? json files, is this like a model in django? Random people talking about outdated Django features I have enough time to deal with everything, but for that I would have to know with what. Can someone explain to me, using a "modern" site like Twitter/YouTube/a web app, what is needed where now? Django tutorials may tell you how to create 1000 forms and create a To Do list, but that's as far as it goes. Down voting questions on stackoverflow, keep it. You knew everything from the beginning, you are so successful ^^ -

How to change the chart data in bootstrap template for Django Project
I'm using the "start bootstrap" template for my Django project. I want to edit my own data in the sample chart. I think I need to change it in the "chart-pie-demo.js" file.

Method not allowed when I do a get request from flutter web to Django server( both in same host)
I've hosted my Django backend server on VPS and used apache2 to run it, when I do requests from my flutter app running locally as debug it works perfectly, then I hosted the flutter web application in the same server under Django itself by creating a directory inside Django root and added a redirect to it from the Django URLs.

Create a new model in Django linked tothe User table
I'm new to Django and I've correctly created my first web app where I can register and login as an user. I'm using the standard from django.contrib.auth.models import User and UserCreationFormto manage this thing. Now, I would like to create a new table in the database to add new fields to the user. I'm already using the standard one such as email, first name, second name, email, username, etc but I would like to extend it by adding the possibility to store the latest time the email has been changed and other info. All those info are not added via the form but are computed by the backend (for instance, every time I want to edit my email on my profile, the relative field on my new table, linked to my profile, change value) To do that I have added on my models.py file the current code from django.db import models from django.contrib.auth.models import User class UserAddInformation(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) last_time_email_change = models.TimeField('Last email changed', auto_now_add=True, blank=True) def __str__(self): return self.user.username And on my admin.py from django.contrib import admin from .models import UserAddInformation admin.site.register(UserAddInformation) The form to edit the email and the view can be found below forms.py class … -

How can I send data to excel file/invoice from django models?
I have a Django model for different companies. When someone does not turn up for work at those companies they call our agency and we send an agent to cover that shift. They then have the manager at that company approve the digital timesheet and the values are saved in a Django model called timesheets. enter image description here My question: I want to implement payroll for over 50 users. Proposed solutions: Do I generate CSV files with the data from the model then pass the data from CSV to an excel file, or is there a better more elegant solution to this problem.

Django Custom Field - Boolean -> CHAR YN
Due to a legacy system I'm trying to get Django boolean fields to save in the dB as a simple 'Y' or 'N' char field (VARCHAR not supported in said legacy system).

Any help appreciated! -
