python - Change a Django form field to a hidden field

Question

I have a Django form with a RegexField, which is very similar to a normal text input field.

In my view, under certain conditions I want to hide it from the user, and trying to keep the form as similar as possible. What's the best way to turn this field into a HiddenInput field?

I know I can set attributes on the field with:

form['fieldname'].field.widget.attr['readonly'] = 'readonly'

And I can set the desired initial value with:

form.initial['fieldname'] = 'mydesiredvalue'

However, that won't change the form of the widget.

What's the best / most "django-y" / least "hacky" way to make this field a <input type="hidden"> field?

This may also be useful: {{ form.field.as_hidden }}
