Question

我正在尝试为登录的玩家打印一个灯具列表，他们可以查看的灯具只是他们所属团队的灯具。基本上我想在userTeams中输出hometeamID / awayteamID =每个teamID的灯具，其中userID = request.user。

灯具型号：

class Fixtures(models.Model):
    fixture = models.CharField(max_length=100)
    hometeamID = 
  models.ForeignKey(Team,related_name='team1',on_delete=models.CASCADE)
   awayteamID = 
  models.ForeignKey(Team,related_name='team2',on_delete=models.CASCADE)
    datetime = models.DateTimeField()
    homegoals = models.PositiveSmallIntegerField()
    awaygoals = models.PositiveSmallIntegerField()
    played = models.NullBooleanField()

UserTeams模型：

class UserTeams(models.Model):
    userID = models.ForeignKey(User,on_delete=models.CASCADE)
    teamID = models.ForeignKey(Team,on_delete=models.CASCADE)

赛程视图：

def fixturesview(request):

    query = Fixtures.objects.all()
    return render(request, 'teammanager/fixtures.html', {
    "fixtures": query
})

HTML：

<p>Fixtures</p>

{%for team in teams%}

    <h3>{{fixtures.fixture}}</h3>

{%endfor%}

如何 - 通过

为用户寻找团队

teams = UserTeams.objects.values_list('teamID', flat=True).filter(userId=user)

然后在

中使用它

fixtures = Fixtures.objects.filter(Q(hometeamID__in=teams) | Q(awayteamID__in=teams))

但是，恕我直言，这些外国字段的名称不应以ID结尾。

Django从UserTeams输出Fixtures
