12. Develop a registration page for student enrolment as done in Module 2 but without page refresh using AJAX.

Step-01: Create new folder:-
⦿ In the same project folder whatever we made earlier create again one new app name called as ‘registration’ using below command.

cd project
python manage.py startapp registration

Step-02: Add the ‘registration’ to the installed_apps list:-
⦿ locate the settings.py file (usually located in the project directory) and open it.
⦿After then add your app name in install_apps list as per below image.

vscode

Step-03: Inside models.py file create a model:- 

from django.db import models

class Student(models.Model):
    fname = models.CharField(max_length=255, null=True)
    lname = models.CharField(max_length=255, null=True)
    email = models.EmailField(null=True, unique=True)
    topic = models.CharField(max_length=255, null=True,)
    languages_used = models.CharField(max_length=255, null=True)
    duration = models.IntegerField(null=True)

    def __str__(self):
        return self.topic
vscode

Step-04: Run the below command to create the model:- 

python manage.py makemigrations
python manage.py migrate

Step-05: Create forms.py file inside the ‘registration’ folder:-

⦿ Open the forms.py file in your Django project directory (registration/forms.py).
⦿ Create a new form that will handle the request using below command.

from django import forms
from .models import Student

class StudentForm(forms.ModelForm):
    class Meta:
        model = Student
        fields = ('fname', 'lname', 'email', 'topic', 'languages_used', 'duration')
        labels = {
            'topic': 'Project Name',
            'languages_used': 'Languages Used',
            'duration': 'Duration (in days)',
            'fname': 'First Name',
            'lname': 'Last Name',
            'email': 'Email'
        }
vscode

Step-06: Inside views.py file create a function:-
⦿ Open the views.py file in your Django project directory (registration/views.py).
⦿ Import the required modules at the top of the file.
⦿ Create a new view function that will handle the request and display the data in the templates.

from django.shortcuts import render
from django.http import JsonResponse
from .models import Student
from .forms import StudentForm

def student_register(request):
    if request.method == 'POST':
        form = StudentForm(request.POST)
        if form.is_valid():
            form.save()
            return JsonResponse({'message': 'Student registered successfully!'})
        else:
            return JsonResponse({'message': ' This email is already registered' })
    else:
        form = StudentForm()
    return render(request, 'student_register.html', {'form': form})

def register_list(request):
    students = Student.objects.all()
    return render(request, 'register_list.html', {'students': students})
vscode

Step-07: Create a template:-
⦿ Right click on ‘registration’ folder, create a new folder named templates.
⦿ Inside the templates folder, create a new file named base.html.
⦿ Inside the templates folder, create a new file named student_register.html.
⦿ Inside the templates folder, create a new file named register_list.html.
⦿ Copy all the different different html file code and paste into all different html file to display the user interface.

Step-08: Add URLs path in the project’s URL patterns:-
⦿ Open the file in your Django project directory (project/urls.py).
⦿ Import the view function at the top of the file.
⦿ Add new URL pattern to the urlpatterns list.

from django.urls import path
from registration import views

urlpatterns = [
    path('', views.student_register, name='student_register'),
    path('register_list', views.register_list, name='register_list'),
]
Screenshot 310

Step-09: Run Your Project:-
⦿ Now setup is completed you can run your project using below command.
⦿ The terminal will display the URL where the development server is running, typically http://127.0.0.1:8000/.
⦿ Copy the URL from the terminal and paste it into your web browser’s address bar to see the output web page.
