我正在尝试建立一个小网站，用户可以在其中设置锦标赛，然后邀请玩家参加他们的锦标赛。
这些是我的锦标赛和邀请模型：
class Tournament(models.Model):
tourney_name = models.CharField(max_length=200, null=False, blank=False)
event = models.ForeignKey(NewsArticle, on_delete=models.DO_NOTHING, related_name='tourneys')
host_user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE)
# player_count_limit = models.PositiveIntegerField(validators=[MaxValueValidator(100)])
player_join_deadline = models.DateField()
fantasy_team_size = models.PositiveIntegerField(validators=[MinValueValidator(5),MaxValueValidator(15)])
created_dt = models.DateTimeField(auto_now_add=True)
last_modified_dt = models.DateTimeField(auto_now=True)
def __str__(self):
return self.tourney_name
def get_absolute_url(self):
return reverse('home')
class Invite(models.Model):
name = models.CharField(max_length=200, blank=True, null=True)
email = models.CharField(max_length=320, null=False, blank=False, validators=[EmailValidator],)
invited_by = models.ForeignKey(get_user_model(), on_delete=models.DO_NOTHING)
invited_for = models.ForeignKey(Tournament, on_delete=models.DO_NOTHING)
created_dt = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.email
def get_absolute_url(self):
return reverse('home')
然后这些是我的观点：
class MakeTourneyView(CreateView):
template_name = 'make_tourney.html'
model = Tournament
form_class = MakeTourneyForm
def form_valid(self, form):
form.instance.host_user = self.request.user
form.save()
return super(MakeTourneyView, self).form_valid(form)
def get_success_url(self):
return reverse('invite_players')
#return reverse('invite_players', kwargs={'tourney_id': self.object.id})
def update_session(self):
tourneyobj = self.get_object()
self.request.session['tourney_id'] = tourneyobj.id
return self.request.session['tourney_id']
class InvitePlayersView(CreateView):
template_name = 'invite_players.html'
model = Invite
form_class = InvitePlayerForm
def form_valid(self, form):
tourney_id = self.request.session['tourney_id']
form.instance.invited_for = Tournament.objects.filter(id=tourney_id).get()
form.instance.invited_by = self.request.user
form.save()
return super(InvitePlayersView, self).form_valid(form)
我做错了，因为 tourney_id 没有设置在 form.instance.invited_for 上；相反，当我单击提交时，我收到 Django 错误消息“KeyError at /tourney/inviteplayers/'tourney_id'”
非常感谢任何帮助！
