Question

我对modelformset自定义字段有问题可以这么说。这是到目前为止的代码，它工作正常：

models.py：

class Workplace(models.Model):
    user = models.ForeignKey(User)
    description = models.TextField(blank=True, null=True)
    organization = models.ForeignKey(Organization)
    position = models.CharField(max_length=250, null=True)
    start = models.DateTimeField(null=True, blank=True)
    end = models.DateTimeField(null=True, blank=True)
    place = models.ForeignKey(Place, null=True, blank=True)
    deleted = models.BooleanField(default=False)

forms.py：

class UserWorkplaceForm(forms.ModelForm):
    class Meta:
        model = Workplace
        labels = {
            'deleted': 'Delete this position'
        }

    def __init__(self, *args, **kwargs):
        super(UserWorkplaceForm, self).__init__(*args, **kwargs)
        self.fields['position'].required = True
        self.fields['organization'].required = True
        self.fields['start'].required = True

views.py：

def settings_workplace(request):
    workplace_formset = modelformset_factory(Workplace,
                                         form=UserWorkplaceForm,
                                         fields=('user', 'position', 'organization', 'start', 'end', 'deleted'),
                                         widgets={'user': forms.HiddenInput(),
                                                  'start': forms.DateInput(attrs={'class': 'workplace-date'}),
                                                  'end': forms.DateInput(attrs={'class': 'workplace-date'}),
                                                  'deleted': forms.CheckboxInput(),
                                                  'organization': forms.TextInput()
                                                  },
                                         extra=0)
    if request.method == "POST":
        formset = workplace_formset(request.POST)
        if formset.is_valid():
            formset.save()
            formset = workplace_formset(queryset=request.user.get_profile().workplace.filter(deleted=False))
    else:
        formset = workplace_formset(queryset=request.user.get_profile().workplace.filter(deleted=False))

    context = {
        'formset': formset
    }

    return render_to_response('accounts/settings_workplaces.html', context, RequestContext(request))

＆＃39;组织＆＃39;字段呈现为Select HTML元素。我无法做到这一点，因为数据库中有数千个组织。我想要做的是将组织显示为文本字段。这就是我在小部件中所做的。但是，这给了我字段的ID，通常不是名称。我有办法同时获得两者吗？我需要一个更好的显示名称，我需要ID以防情况编辑（在不同的字段上），因为该字段是必需的。

有什么想法吗？

您可以将其设为ChoiceField，其中第一个值是组织的ID，第二个值是组织的人类可读名称吗？这是我建议处理这种情况。以下是关于在Django中设置“选择”的文档：

Django ModelFormset名称而不是外键字段中的ID
