请问我为什么在模板中显示“收藏夹”时收到此错误消息
QuerySet object has no attribute game_id
我试图取代game_id的game，id_game但没有...
view.py
from django.contrib import messages
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)
遍历查询集时，您可以访问game_id每个实例的。您无法在查询集上访问它。
您可以在视图中循环查询集，
favs = FavoriteGames.objects.filter(user_id=id_user)
for fav in favs:
game_id = game_id
或在模板中：
{% for fav in favs %}
{{ fav.game_id }}
{% endfor %}
如果只需要game_idsqueryset中的，则可以使用values_list：
game_ids = FavoriteGames.objects.filter(user_id=id_user).values_list('game_id', flat=True)
