Using [[https://docs.djangoproject.com/en/2.0/topics/i18n/translation
/#translating-url-patterns|translatable URL patterns]] like this
{{{
from django.utils.translation import gettext_lazy as _
p = path(_('example/'), ExampleView.as_view())
print(p)
# or
p = re_path(_(r'^example/$'), ExampleView.as_view())
print(p)
}}}
causes
{{{
TypeError: __str__ returned non-string (type __proxy__)
}}}
It should print a string representation of the URL pattern instead:
{{{
<URLPattern 'example/''>
}}}
This affects some consumers of URL patterns:
-
[[https://docs.djangoproject.com/en/2.0/ref/contrib/admin/admindocs/|django.contrib.admindocs]]
returns HTTP500 for ''admin/docs/views/''
- possibly Django REST Framework ''SchemaGenerator,'' when fixing
[[https://github.com/encode/django-rest-framework/issues/5675|this error]]
by using ''str(pattern)''
