#34380 closed Cleanup/optimization (fixed)

Make URLField assume "https".

Description

In django.forms.fields.URLField.to_python the assumption is made that the http (no S) is a good default scheme for URLs that do not specify a scheme when submitted.

Entering example.com in a URLField will give http://example.com as cleaned data.

Ref: https://github.com/django/django/blame/main/django/forms/fields.py#L772-L774

I think URLField should assume the safe option https.

I've notified the security team, and they didn't see this as a security issue.

Thanks for this report. As far as I'm aware, we should switch the default to "https" via the deprecation process (see #32375 for a similar change).

In 7bbbadc6:

Fixed #34380 -- Allowed specifying a default URL scheme in forms.URLField.

This also deprecates "http" as the default scheme.

There is no (easy) way to pass/use assume_scheme via django.db.models.fields.URLField (directly), avoiding the deprecation messages (since using the transitional setting FORMS_URLFIELD_ASSUME_HTTPS also triggers a deprecation message already).

Should django.db.models.fields.URLField accept/handle assume_scheme?

Or is the way to go to use FORMS_URLFIELD_ASSUME_HTTPS for now, ignoring its DeprecationMessage, and to remove the setting with Django 6.0 again?

Might be nice to document this then in the release notes / documentation.

That was our idea (check out the entire discussion). If you agree for an early adoption of the new (Django 6.0+) default, set FORMS_URLFIELD_ASSUME_HTTPS = True and ignore it's deprecation warning during Django 5.X release cycle with e.g. warnings.filterwarnings("ignore", "FORMS_URLFIELD_ASSUME_HTTPS", category=RemovedInDjango60Warning). In Django 6.0 you will be able to remove both the FORMS_URLFIELD_ASSUME_HTTPS setting and a warnings filter.
