Question

型号：

class MyTeam(models.Model):
    user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    match = models.ForeignKey(Match, on_delete=models.SET_NULL, null=True, related_name='match_set')
    mega_league = models.ForeignKey(MegaLeague, on_delete=models.SET_NULL, null=True, blank=True, related_name='mega_league_set')
    captain_first_team = models.ForeignKey(FirstTeamPlayer, on_delete=models.SET_NULL, null=True, blank=True, related_name="captain_second_team_set")
    captain_second_team = models.ForeignKey(SecondTeamPlayer, on_delete=models.SET_NULL, null=True, blank=True, related_name="captain_second_team_set")
    team_player_first_team = models.ManyToManyField(FirstTeamPlayer, blank=True, related_name="team_player_first_team_set")
    team_player_second_team = models.ManyToManyField(SecondTeamPlayer, blank=True, related_name="team_player_second_team_set")

首先，我需要在一个字段中添加这些captain_first_team和captain_second_team（例如在一个字段中添加FirstTeamPlayer和SecondTeamPlayer）。怎么样？

观看次数：

def add_to_my_team_from_team_create(request, match_id):
    match = get_object_or_404(Match, pk=match_id)
    my_team = MyTeam.objects.create(match=match, user=request.user)
    return redirect('team_create', match.pk, my_team.pk)

def team_create(request, match_id, team_id):
    match = get_object_or_404(Match, pk=match_id)
    my_team = get_object_or_404(MyTeam, pk=team_id)
    first_team_player = match.first_team.first_team_player.all()
    second_team_player = match.second_team.second_team_player.all()

    context = {
        'match': match,
        'my_team': my_team,
        'first_team_player': first_team_player,
        'second_team_player': second_team_player,
    }
    return render(request, 'main/team_create.html', context=context)

def add_first_team_player(request, match_id, team_id, player_id):
    match = get_object_or_404(Match, pk=match_id)
    my_team = get_object_or_404(MyTeam.objects.filter(user=request.user, match=match.pk), pk=team_id)
    first_team_player = get_object_or_404(match.first_team.first_team_player, pk=player_id)
    my_team.team_player_first_team.add(first_team_player)
    return redirect('team_create', match.pk, my_team.pk)

def remove_first_team_player(request, match_id, team_id, player_id):
    match = get_object_or_404(Match, pk=match_id)
    my_team = get_object_or_404(MyTeam.objects.filter(user=request.user, match=match.pk), pk=team_id)
    first_team_player = get_object_or_404(match.first_team.first_team_player, pk=player_id)
    my_team.team_player_first_team.remove(first_team_player)
    return redirect('team_create', match.pk, my_team.pk)

在视图中，首先，我使用MyTeam函数创建一个add_to_my_team_from_team_create，然后使用add_first_team_player在字段上添加数据，还可以使用remove_first_team_player从字段中删除数据。但是我需要相反的一个。也就是说，我需要添加字段，然后在模板中按保存按钮时，它将保存在MyTeam中。

team_create模板：

{% for first_team_player in first_team_player %}
    <tr id="wk">
       <td>
          <img src="{{ first_team_player.player_image.url }}">
          <div>
              {{ first_team_player.player_name }} <br>
              {{ match.first_team.name }}
          </div>
        </td>
        <td>
           {% if first_team_player in my_team.team_player_first_team.all %}
              <a href="{% url 'remove_first_team_player' match.pk my_team.pk first_team_player.pk %}"><button type="button" class="btn btn-danger btn-sm">Remove -</button></a>
           {% else %}
              <a href="{% url 'add_first_team_player' match.pk my_team.pk first_team_player.pk %}"><button type="button" class="btn btn-primary btn-sm">Add +</button></a>
           {% endif %}
         </td>
     </tr>
{% endfor %}
<a href=""><button type="button" class="btn btn-primary btn-sm">Save</button></a>

当我按下Add +按钮然后将此播放器添加到MyTeam模型中时，在模板中；当按下Remove -按钮时此播放器将从该模型中删除。

现在我的问题全是2分：

在创建MyTeam时，我想在此提出一些逻辑。我需要来自1个团队的最多7名玩家（当最大玩家添加然后Add +按钮将被禁用）和来自另一1个团队的其他玩家，总共玩家将为11（当具有总玩家添加然后Add +按钮将被禁用对于所有玩家）。首先，Save按钮保持禁用状态，当MyTeam中有11位玩家完成比赛时，它将启用，按下这些玩家将保存到MyTeam。这样，一个QuerySet就可以创建。
如果我创建MyTeam 1st并在其字段中添加数据，则它可能是一个空团队。但是在这里我不能空手。因此，第一，我需要在字段上添加数据，然后按Save按钮，它将创建一个包含所有数据的新团队。

我该如何解决这2个问题？

为了更好地理解，我想像这样 team create of dream11 。 在调查了给定的链接后，请详细帮助我。
