Bases: django.forms.forms.Form
A simple form for selecting a range of time.
Bases: horizon.forms.base.SelfHandlingMixin, django.forms.forms.Form
A base Form class which includes processing logic in its subclasses.
Adds an error to the form’s error dictionary after validation based on problems reported via the API. This is useful when you wish for API errors to appear as errors on the form rather than using the messages framework.
Sets a warning on the form.
Unlike NON_FIELD_ERRORS, this doesn’t fail form validation.
