from django import forms
from .models import MyModel, RelatedModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        exclude = ['field1', 'field2']

class RelatedModelForm(forms.ModelForm):
    class Meta:
        model = RelatedModel
        exclude = ['field1', 'field2']

MyModelFormSet = inlineformset_factory(MyModel, RelatedModel, form=RelatedModelForm, exclude=['field1', 'field2'])

class MyModelForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(MyModelForm, self).__init__(*args, **kwargs)
        del self.fields['field1']
        del self.fields['field2']

    class Meta:
        model = MyModel

{% for field in formset.management_form %}
    {% if field.name != 'field1' and field.name != 'field2' %}
        {{ field }}
