如何验证用户是否拥有"一个模型实例

我有以下型号:

class UserProfile(models.Model):
    user = models.OneToOneField(User)

class Site(models.Model):
    user = models.ForeignKey(User)
    site_name = models.CharField(max_length=128, blank=False, null=False)

class Team(models.Model):
    site = models.ForeignKey(Site)
    team_member_name = models.CharField(default='name', max_length=128, blank=False, null=False)

我有一个通过网址传递team_member ID的视图:

Urls.py:

url(r'^team/(?P<team_member_id>\d+)/$', 'team.views.home', name='team_view_team_member')

Views.py:

@login_required
def home(request, team_member_id=None):
    team_member = Team.objects.get(id=team_member_id)

请注意,有许多Team个实例(即许多团队成员)具有相同的Site_id

如何测试request.usersite_id返回的team_member是否相同?如果我想在多个视图中使用它,是否有一种简单的方法可以重复此操作?

试试这个:

team_member = Team.objects.get(id=team_member_id)
if team_member.site.id == request.user.site_set.all().first().id:
   print "same site"
else:
   print "different site"

希望这有帮助。

# Site for user in request
req_user_site = Site.objects.get(user=request.user)  # Use filter if it will return more than one object

# Site for team member in url
sites = Site.objects.filter(team__pk=team_member_id)

# Then compare
if req_user_site in sites:
    print "have the same"
else:
    print "don't"
