Question

我希望登录用户能够将用户添加到他们创建的团队中。目前我创建了一个表单，允许用户选择他们想要添加的用户和团队，但他们可以从数据库中的每个团队中选择，而不仅仅是他们创建的团队。有任何想法吗？这些是我的模型，视图和我创建的形式。还应该感谢有关放入HTML文件的内容的帮助。

型号：

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


class Team(models.Model):
    name = models.CharField(max_length=100)
    venue = models.CharField(max_length=100)
    countryID = models.ForeignKey(Countries, on_delete=models.CASCADE)
    owner = models.ForeignKey(User)

查看：

def invite(request):
    if request.method == 'POST':
        form = InvitePlayerForm(request.POST)
        if form.is_valid():
            userteam = form.save(commit=False)
            userteam.save()

    else:
        form = InvitePlayerForm()
        query = UserTeams.objects.all()
    return render(request, 'teammanager/invite.html', {
        "invite": query,
        "form": form
})

形式：

class InvitePlayerForm(forms.ModelForm):

    class Meta: 
        model = UserTeams
        fields = ['userID','teamID']

HTML：

{% extends "teammanager/header.html" %}

{% block content %}


<html>
<body>
            <h4>Invite players to your team</h4>

    <form method="post">
    {% csrf_token %}
    {{ form.as_p }}


</form>


{% endblock %}

像这样修改你的表单它会根据userteam对象进行FK过滤。

class InvitePlayerForm(forms.ModelForm):

    class Meta: 
        model = UserTeams
        fields = ['userID','teamID']

    def __init__(self,user,*args,**kwargs):
        super(InvitePlayerForm,self ).__init__(*args,**kwargs) 
        self.fields['teamID'].queryset = Team.objects.filter(id__in = UserTeam.objects.filter(userID = user))

Django将用户添加到＆＃39; team＆＃39;
