Setting Up the Project

Use the below command to start your project:

django-admin startproject <project_name>
cd <project_name>
python manage.py startapp user

user/model.py: Here we have created a User table with name, and email field in the table.

Python

from django.db import models
from django.core.validators import validate_email

class User(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField(validators=[validate_email])

    def __str__(self):
        return self.name

user/form.py: Here we created a form to register a user request.

Python

from django import forms
from .models import User

class UserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ['name', 'email']

user/views.py: This file uses the form and renders a template to collect user data an dverify '.

Python

from django.shortcuts import render
from .forms import UserForm

def create_user(request):
    if request.method == 'POST':
        form = UserForm(request.POST)
        if form.is_valid():
            form.save()
    else:
        form = UserForm()

    return render(request, 'index.html', {'form': form})


def home(request):

from . import views

urlpatterns = [
    path('/home', views.home, name='home'),
    path('', views.create_user, name='create_user'),
]

urls.py: Add the necessary URL patterns in your project's urls.py.
