Create Parent Class object from child class's ModelForm

I have a Model 'Appointment'. In that class patient is associated with built-in User model.I have made a modelform for that class. Is it possible to instantiate an object of another class (User in field patient) from inside the same form. I am not able to access User Model's field in the form. How can this be done ?

class Appointment(models.Model):
    doctor = models.ForeignKey(Doctor)
    clinic = models.ForeignKey(Clinic, null=True, blank=True)
    hospital = models.ForeignKey(Hospital, null=True, blank=True)
    day = models.DateField()
    time = models.TimeField()
    patient = models.ForeignKey(User)

I have created a ModelForm for this model as below:

class HospitalCreateAppointmentForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(HospitalCreateAppointmentForm, self).__init__(*args, **kwargs)
        for field in iter(self.fields):
                self.fields[field].widget.attrs.update({
                    'class': 'form-control'
                })

    class Meta:
        model = Appointment
        fields = ['doctor','hospital','day','time','patient']
        widgets = {
            'day': forms.SelectDateWidget(),
        }

I am not sure purpose behind instantiating user object in HospitalCreateAppointmentForm. However, just in case you really need, you have to import User model in form file. For example if your HospitalCreateAppointmentFor is in forms.py, import User module like 

from django.contrib.auth.models import User

And you can access field like:

User._meta.fields
