Question

我正在尝试以django形式创建一对多关系，其中我创建了一个具有id的客户，并且我想使用该客户的信息来创建新表单

models.py 从django.db导入模型

# Create your models here.
class Patient(models.Model):
    name = models.CharField(max_length=200);
    phone = models.CharField(max_length=20);
    address = models.TextField();
    Patient_id = models.AutoField(primary_key=True);
    Gender = models.CharField(max_length=50);

class Ipd(models.Model):
    Presenting_complaints = models.CharField(max_length=300);
    Reason_admission = models.CharField(max_length=300);
    patient = models.ForeignKey('Patient',on_delete=models.CASCADE

forms.py 从django.forms导入ModelForm 从Django导入表格从.models import Patient，Ipd

class PatientForm(ModelForm):
    OPTIONS = (
        ('',''),
        ('Doctor1','Doctor1'),
        ('Doctor2','Doctor2'),

    )
    OPTIONS2 = (
        ('Male', 'Male'),
        ('Female', 'Female'),

    )
    Gender= forms.TypedChoiceField(required=False, choices=OPTIONS2, 
widget=forms.RadioSelect)
consultant = forms.ChoiceField(choices=OPTIONS)

    class Meta:
        model = Patient
        fields = ['name','phone','address','Patient_id','consultant','Gender']

class IpdForm (ModelForm):
    patient = Patient.objects.all()

    class Meta:


        model = Ipd
        fields = ('Presenting_complaints','Reason_admission', 'patient')

def save(self, commit=True):

    instance = super().save(commit)
    # set Car reverse foreign key from the Person model
    instance.patient_set.add(self.cleaned_data['patient'])
    return instance

views.py

@login_required
def new(request):
    if request.POST:
        form = PatientForm(request.POST)
        if form.is_valid():
            if form.save():
                return redirect('/', messages.success(request, 'Patient is 
successfully created.', 'alert-success'))
            else:
                return redirect('/', messages.error(request, 'Data is not 
saved', 'alert-danger'))
        else:
            return redirect('/', messages.error(request, 'Form is not valid', 'alert-danger'))
    else:
        form = PatientForm()
        return render(request, 'new.html', {'form':form})

我想用主键链接两种形式

如何用主键链接多个表格？
