如何将 request.user 添加到 django 中的团队成员的 manytomanyfield？

Question

我试图为团队成员创建一个自定义团队模型，该模型具有一个 manytomanyfield，现在我有一个允许用户创建自己的团队的表单，但我不明白如何将 request.user 添加到成员的团队。以下是代码：

models.py

class Team(models.Model):
    name = models.CharField(max_length=64, unique=True)
    description = models.CharField(max_length=1024)
    created_at = models.DateTimeField(auto_now_add=True)
    members = models.ManyToManyField(User, through='Member')

    def __str__(self):
        return f"Team: {self.name} created on {self.created_at}\nMember(s): {self.members}"


class Member(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    team = models.ForeignKey(Team, on_delete=models.CASCADE, blank=True)

forms.py

class TeamRegistrationForm(ModelForm):
    class Meta:
        model = Team
        fields = ["name", "description"]

views.py

@login_required(login_url="/login/")
def teamregister(request):
    if request.method == "POST":
        form = TeamRegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            form.instance.members.add(request.user) # doesn't work :[
            print(form.save())
            messages.success(request, "Your team has been successfully registered!")
            return redirect("dashboard")
    else:
        form = TeamRegistrationForm()

    return render(request, "users/team.html", {"form": form})

我尝试使用form.instance.members.add(request.user) 将已登录用户添加到团队成员中，但没有成功。请帮忙：[

已添加到关系中，但您不打印关系中的项目。你打印经理。确实，你写{self.members}，那是经理，你应该把它改写成{self.manager<b>.all()</b>}。 Manager 将，除非你实现它否则返回<i>ModelName</i>.None：

class Team(models.Model):
    # …

    def __str__(self):
        return f'Team: {self.name} created on {self.created_at}\nMember(s): {self.members.all()}'
