from django.conf import settings
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from django.shortcuts import render
from start.models import Games, FavoriteGames
import urllib, json

def view_recap(request):
    if request.user.is_authenticated():
        username = request.user.username
        id_user = request.user.id
        fav = FavoriteGames.objects.filter(user_id=id_user).game_id
        return render(request, 'recap.html', locals())
    else:
        from start.views import view_logoff
        from start.views import view_logon
        messages.add_message(request, messages.INFO, 'Vous devez être connecté pour accéder à cette page.')
        return redirect(view_logon)

models.py

from django.db import models
from django.conf import settings

# Create your models here.
class Games(models.Model):
    guid = models.CharField(max_length=100, unique=True, null=False, verbose_name="GUID")
    title = models.CharField(max_length=100, null=False, verbose_name="Titre")
    logo = models.CharField(max_length=100, null=True, blank=True, verbose_name="Logo")
    date = models.DateTimeField(auto_now_add=True, auto_now=False, verbose_name="Date de création")
    update = models.DateTimeField(auto_now=True, verbose_name="Dernière modification")
    def __str__(self):
        return self.title

class FavoriteGames(models.Model):
    game = models.ForeignKey('Games')
    user = models.ForeignKey(settings.AUTH_USER_MODEL)

When you loop through the queryset you can access the game_id for each instance. You can't access it on the queryset.

You can loop through the queryset in the view,

favs = FavoriteGames.objects.filter(user_id=id_user)

for fav in favs:
    game_id = game_id

or in the template:

{% for fav in favs %}
  {{ fav.game_id }}
{% endfor %}

If you only need the game_ids from the queryset, you could use values_list:

game_ids = FavoriteGames.objects.filter(user_id=id_user).values_list('game_id', flat=True)
