✅

To make a field in a ModelField a hidden field, use a HiddenInput widget. The ModelForm uses a sensible default widget for all the fields, you just need to override it when the object is constructed.

class TagStatusForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        widgets = {'tag': forms.HiddenInput()}

There are 3 possible ways (AFAIK) to render hidden fields in Django –

1. You could declare a field normally in forms.py but in your templates html file use {{ form.field.as_hidden }}

2. in forms.py directly use hidden input widget.

class MyForm(forms.Form):
    hidden_field = forms.CharField(widget=forms.HiddenInput())

Once you make the field a hidden input, you could populate the value of the field in templates. Now your hidden field is ready for rendering.

3. Regular form equivalent (thanks to @Modelesq for sharing this nugget). Here no Django is involved. Changes are done at HTML template level. <input type="hidden" name="tag" value="{{ tag.name }}" />

I was looking for a way to HIDE ALL INPUTS : 

class TagStatusForm(forms.ModelForm):
    class Meta:
        model = TagStatus

    def __init__(self, *args, **kwargs):
        super(TagStatusForm, self).__init__(*args, **kwargs)
        for field in self.fields:
            self.fields[field].widget = forms.HiddenInput()

I posted a way to do it with generic class-based views here:

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'
