Implementing @check_honeypot on Django Wagtail Form

Question

I am trying to implement Honeypot into a Wagtail email form, but I don't understand how to add the @check_honeypot decorator to a class in models.py, which checks the honeypotfor validity.

To set up Honeypot, it requires that I add the @check_honeypot decorator to the form view in my views.py. Unfortunately, wagtail does not utilize views.py and instead the form is built in the models.py.

How to I implement honeypot decorator onto a Wagtail form?

Honeypot repo: https://github.com/jamesturk/django-honeypot Snippet from honeypot instructions:

To ensure that the honeypot field is both present and correct you will >need to use check_honeypot decorator from honeypot.decorators:

from honeypot.decorators import check_honeypot

@check_honeypot(field_name='hp_field_name') def post_comment(request): ... @check_honeypot def other_post_view(request): ...

SOLUTION:

@method_decorator(check_honeypot)
def render_landing_page

models.py

class FormField(AbstractFormField):
    page = ParentalKey('FormPage', on_delete=models.CASCADE, related_name='form_fields')
