Read Operations

In this chapter, we'll start fetching records from the database and displaying them on the user's page.

Code Explanation

from .models import Note

def read_content(request):
    # Retrieving all notes from the database
    all_notes = Note.objects.all()
    return HttpResponse(all_notes)

1. from .models import Note: Imports the Note model from the current Django application. Models in Django are classes that describe the structure of database tables;

2. def read_content(request):: Defines the read_content function, which will handle HTTP requests. The function takes a request object containing information about the client's request;

3. all_notes = Note.objects.all(): Utilizes Django's Object-Relational Mapping (ORM) to query the database and retrieve all objects of the Note model`;

4. return HttpResponse(all_notes): We are sending information to the HTML template.

from .views import read_content, send_content

urlpatterns = [
    path('', read_content),
    path('send/', send_content),
]
