Description

Hi,

I am currently using an URLField to store an AWS S3 URL for one of my models (s3://bucket/prefix).

URLField uses urllib to validate the URL and finds this URL consistent; but the URL validator used by Django Admin is different and demands that the scheme of the URL must be one of schemes = ['http', 'https', 'ftp', 'ftps'].

The effect is that you can't modify an instance on Django Admin because it blocks saving.

The bug is in Django 2.2 and 3.0.

Resolution: → duplicate
Status: new → closed
Summary: Make URL validators consistent between django/core/validators.URLValidator (for admin) django/db/models/fields.URLField (urllib) → Make URL validators consistent.
Version: 2.2 → master

In both cases Django uses the same validator django.core.validators.URLValidator. Note that Model.save() doesn't validate fields (see ​documentation). You can subclass URLField and add s3 to the list of accepted schemas, e.g.

class MyURLField(URLField):
    default_validators = [validators.URLValidator(schemes=['s3', 'http', 'https', 'ftp', 'ftps'])]

Solving #25594 should make it easier.

Duplicate of #26418.
