------------------------------------------------+------------------------
When in the `project/urls.py` another `urls.py` is included, `./manage.py
migrate` forces `get_language` to return `None` instead of
`settings.LANGUAGE_CODE`.
Only in `Django-3.1`. More specifically:
This is how `get_language` is used:
{{{
class PendingConsentForm(forms.ModelForm):
class Meta:
model = Term
fields = (
"summary_{0}".format(get_language()),
)
}}}
* Python-3.8.5
* Django-3.1
* This is the simple failing project: https://github.com/raratiru/django-
fail-language
**Steps to reproduce:**
* Fresh Django-3.1 install
* `pip install --index-url https://test.pypi.org/simple/ django-fail-
language`
* Add `'letsagree',` in `INSTALLED_APPS` of `project/settings.py`
* Include `letsagree.urls` in `project/urls.py`:
{{{
urlpatterns = [
...
path('', include('letsagree.urls')),
...
]
}}}
* `./manage.py migrate` fails with: `django.core.exceptions.FieldError:
Unknown field(s) (summary_None) specified for Term`.
* `./manage.py makemigrations` will correctly return the value of
`settings.LANGUAGE_CODE`:
`django.core.exceptions.FieldError: Unknown field(s) (summary_en-us)
specified for Term`
* In a virtualenv with `Django-3.0` `./manage.py migrate` will behave as
expected:
`django.core.exceptions.FieldError: Unknown field(s) (summary_en-us)
specified for Term`:
Expected because `en-us` is the default for `settings.LANGUAGE_CODE`.
