Ah, I see.
It looks like I can use modelform_factory. So:
class PatientCreate(LoginRequiredMixin, UserOrgRequiredMixin, CreateView):
model = models.Patient
fields = ['name', 'caregiver_name', 'sex', 'birth_date',
'residence', 'country']
becomes
from django.forms.models import modelform_factory
_patient_create_form = modelform_factory(
models.Patient,
fields=['name', 'caregiver_name', 'sex', 'birth_date',
'residence', 'country'])
class PatientCreate(LoginRequiredMixin, UserOrgRequiredMixin, CreateView):
form_class = _patient_create_form
template_name = 'healthdbapp/patient_form.html'
and then I can add the widgets:
from django.forms import HiddenInput
from django.forms.models import modelform_factory
_patient_create_form = modelform_factory(
models.Patient,
fields=['name', 'caregiver_name', 'sex', 'birth_date',
'residence', 'country'],
widgets={'country': HiddenInput()})
class PatientCreate(LoginRequiredMixin, UserOrgRequiredMixin, CreateView):
form_class = _patient_create_form
template_name = 'healthdbapp/patient_form.html'
Works for me.
