Accessing a Specific User's Favorite
In this task, we'll display the title of a user's favorite. We'll start by getting an object corresponding to the user (change the name of the user as appropriate to match your database):
user = User.objects.
get(username='steve')
Then, to find the title of the favorite, just pass the get method the User object to get the user's favorite, and use the title field to find the favorite's title:
user = User.objects.
get(username='steve')
title = Favorite.objects.
get(user=user).title
To access a specific user’s favorite:
- Using a text editor, edit chapter4\favorites\views.py, adding the code shown in Listing 4.13.
Listing 4.13. The edited views.py file.
from django.http import HttpResponse from django.contrib.auth.models import User from favorites.models import * def main_page(request): output = ''' <html> <head> <title> Connecting to the model </title> </head> <body> <h1> Connecting to the model </h1> Title of steve's favorite: %s </body> </html>''' % ( . . . ) return HttpResponse(output) - Add the code to actually access the title of the user's favorite and display it, shown in Listing 4.14.
Listing 4.14. The completed views.py file.
from django.http import HttpResponse from django.contrib.auth.models import User from favorites.models import * def main_page(request): user = User.objects.get(username='steve') title = Favorite.objects.get(user=user) title output = ''' <html> <head> <title> Connecting to the model </title> </head> <body> <h1> Connecting to the model </h1> Title of steve's favorite: %s </body> </html>''' % ( title ) return HttpResponse(output) - Save views.py.
