n view.py under index function, get the list of question and store them in an object then pass them to the url

  1. Import model from .models import Listing

  2. Save data from DB into an object listings = Listing.objects.all()

  3. Create the dictionary to pass to the template


  context = {
        'listings' : listings
    }
 

4. Pass the context return render(request, ‘listings/listings.html’, context)

5. Use the data in template {{ listing.listing.title }}

6. Show many rows use for loop

Linking to a Single Record

The id must be passed in the html link, urls.py, and views.py

1. In the HTML file you want to use

2. In urls.py


path('', views.listing, name='listing'),

3. In views.py


def listing(request, listing_id):
    return render(request, 'listings/listing.html')

Example


from django.shortcuts import render
from .models import Listing

def index(request):
    listings = Listing.objects.all()
    context = {
        'listings' : listings
    }
    return render(request, 'listings/listings.html', context)

Edit the HTML file
