In my view, under certain conditions I want to hide it from

Answer 1

For normal form you can do

class MyModelForm(forms.ModelForm):
    slug = forms.CharField(widget=forms.HiddenInput())

If you have model form you can do the following

class MyModelForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        fields = ('slug', 'ext')
        widgets = {'slug': forms.HiddenInput()}

You can also override __init__ method

class Myform(forms.Form):
    def __init__(self, *args, **kwargs):
        super(Myform, self).__init__(*args, **kwargs)
        self.fields['slug'].widget = forms.HiddenInput()
