Question

我有一个模特：

class HospitalDoctor(models.Model):


hospital = models.ForeignKey(Hospital)
full_name = models.CharField(max_length=100, unique=True)
expertization = models.CharField(max_length=50)
nmc_no = models.CharField(max_length=20)
timings = models.ManyToManyField('Timing', related_name='shift_timing')
appointment = models.IntegerField(default=0)

def __unicode__(self):
    return self.full_name

class Timing(models.Model):
hospital = models.ForeignKey(Hospital)
doctor = models.ForeignKey(HospitalDoctor)
day = models.CharField(max_length=20)
mng_start = models.IntegerField()
mng_end = models.IntegerField()
eve_start = models.IntegerField()
eve_end = models.IntegerField()

def __unicode__(self):
    return self.day

我为此创建了表单：

class HospitalDoctorInfoForm(forms.ModelForm):

class Meta:
    model = HospitalDoctor
    fields = ('hospital','full_name', 'expertization', 'nmc_no')

class TimingForm(forms.ModelForm):
class Meta:
    model = Timing
    fields = ('day','mng_start', 'mng_end', 'eve_start', 'eve_end')

在这里，我想创建有关医生的信息，例如来自HospitalDoctorInfoForm的个人信息以及来自TimingForm的一周时间表。

我认为我应该在TimingForm中使用formsets进行7天的时间安排，其中包含星期日，星期一的初始值......

我写了一些观点：

class HospitalDoctorAddView(CreateView):

template_name = "hospital_doctor_add.html"
model = HospitalDoctor

def post(self, request, *args, **kwargs):

    info_form = HospitalDoctorInfoForm(request.POST)
    formset = modelformset_factory(request.POST, Timing, form=TimingForm, extra=7)

    if formset.is_valid() and info_form.is_valid():
        self.formset_save(formset)
        self.info_form_save(info_form)

    context['formset'] = formset

    return render(request, self.template_name, context)

def formset_save(self, form):
    frm = Timing()
    frm.hospital = self.request.user
    frm.mng_start = form.cleaned_data['mng_start']
    frm.mng_end = form.cleaned_data['mng_end']
    frm.eve_start = form.cleaned_data['eve_start']
    frm.eve_end = form.cleaned_data['eve_end']
    frm.save()

def info_form_save(self, form):
    info = HospitalDoctor()
    info.hospital = self.request.user
    info.full_name = form.cleaned_data['full_name']
    info.expertization = form.cleaned_data['expertization']
    info.nmc_no = form.cleaned_data['nmc_no']
    info.save()

当我这样做时，它会给出错误说＆＃34;创建没有＆＃39;字段的ModelForm＆＃39;属性或＆＃39;排除＆＃39;属性已弃用 - 表单TimingForm需要更新＆＃34 ;.我需要帮助。我正在做什么或者有另一种方法来实现这一点。

https://docs.djangoproject.com/en/dev/ref/forms/models/#django.forms.models.inlineformset_factory

from django.core.urlresolvers import reverse
from django.forms.models import inlineformset_factory

TimingFormSet = inlineformset_factory(HospitalDoctor, Timing, form=TimingForm, extra=7)

class HospitalDoctorAddView(CreateView):
   ...

    def get_context_data(self, **kwargs):
        context = super(HospitalDoctorAddView, self).get_context_data(**kwargs)
        context['formset'] = TimingFormSet(instance=Timing())

        return context

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)
        formset = TimingFormSet(request.POST, request.FILES)  # request.FILES for files, remove if don't send files

        if form.is_valid() and formset.is_valid():
            return self.form_valid(form, formset)
        else:
            return self.form_invalid(form, formset)

    def form_valid(self, form, formset):
        self.object = form.save()
        formset.instance = self.object
        formset.save()

        return HttpResponseRedirect(self.get_success_url())

    def form_invalid(self, form, formset):
        return self.render_to_response(
            self.get_context_data(
                form=form,
                formset=formset
            )
        )

    def get_success_url(self):
        return reverse('some_app:url_name')

django多种形式与formsets
