我正在努力解决这个问题，希望这里有人可以帮助我。我有一个名为“Team”的模型，它有一个 ForeignKey 字段，对应于我在（“Department”）上显示 ModelForm 的页面。由于它在页面上，我想在后端（视图或表单）中设置 ForeignKey，而不是让用户选择它。

按照其他示例进行设置，以便将值添加到表单部分，但是当我提交表单时，我在终端中收到以下错误（随后是 request.POST 打印输出）：

<ul class="errorlist"><li>Department<ul class="errorlist"><li>This field is required.</li></ul></li></ul>

<QueryDict: {'csrfmiddlewaretoken': ['KeEJF7KFr6l9dbkmZWA7u4Qg3eKqqFGcB2qq2AIEmilLP87AySi60ig3hJl6TBS0'], 'title': ['test'], 'description': [''], 'events': [''], 'current_status': [''], 'notes': [''], 'impact': [''], 'timeliness': [''], 'likelihood': [''], 'risk': [''], 'summary': [''], 'documents': ['']}>

形式：

class TeamFormCreate(forms.ModelForm):

    class Meta:
        model = Team
        fields = ('department', 'title', 'description', 'events', 'current_status', 'notes', 'impact',
                  'timeliness', 'likelihood', 'risk', 'summary', 'documents')

看法：

@login_required
def new_team(request):

    if request.method == "POST":
        form = TeamFormCreate(request.POST)
        if form.is_valid():
            team = form.save(commit=False)
            team.author = request.user
            team.modified_date = timezone.now()
            team.save()
            return redirect('/dashboard/1')
        else:
            return redirect('/dashboard/1')

    else:
        cd_id = request.GET.get('id', None)
        form = TeamFormCreate(cd_id)
        return render(request, 'app/sidebar_team.html', {'form': form})

模型：

class Team(models.Model):
    department = models.ForeignKey('MyApp.Department', related_name='teams')
    author = models.ForeignKey('auth.User')
    modified_date = models.DateTimeField(default=timezone.now)
    title = models.CharField(max_length=200)
    description = models.TextField(blank=True, null=True)
    events = models.TextField(blank=True, null=True)
    current_status = models.TextField(blank=True, null=True)
    notes = models.TextField(blank=True, null=True)
    order = models.IntegerField(default=0)
    # icon = models.ImageField()

    # Document files
    summary = models.FileField(upload_to='team', blank=True, null=True)
    documents = models.FileField(upload_to='team', blank=True, null=True)

    # Ratings
    RATING_CHOICES = [(x, x) for x in range(1, 6)]
    impact = models.IntegerField(choices=RATING_CHOICES, blank=True, null=True)
    timeliness = models.IntegerField(choices=RATING_CHOICES, blank=True, null=True)
    likelihood = models.IntegerField(choices=RATING_CHOICES, blank=True, null=True)
    risk = models.IntegerField(choices=RATING_CHOICES, blank=True, null=True)

    class Meta:
        ordering = ['order']

    def __str__(self):
        return self.title

我终于能够通过将我的视图从基于函数的视图更改为以下基于类的视图来完成这项工作。

# Required Imports
from django.views.generic import CreateView
from django.contrib.auth.mixins import LoginRequiredMixin

class TeamCreate(LoginRequiredMixin, CreateView):
    model = Team
    form_class = TeamFormCreate
    template_name = 'app/sidebar_team.html'

    def get_initial(self):
        pk = self.request.GET.get('id')
        return {
            'department': pk,
        }

    def post(self, request, *args, **kwargs):
        form = TeamFormUpdate(request.POST)
        if form.is_valid():
            team = form.save(commit=False)
            team.author = request.user
            team.modified_date = timezone.now()
            team.save()
            return redirect('/dashboard/' + str(team.department.id))
        else:
            return redirect('/dashboard/' + str(form.department.id))
