Following the steps in #26488 results in the `InvalidBasesError` error
described in that ticket until 0d3c616fbb2f49fa7ff6809e5a6777275352b35b
where something like this happens:
{{{
File "/home/tim/code/django/django/core/management/commands/migrate.py",
line 62, in _run_checks
issues.extend(super(Command, self).check(**kwargs))
File "/home/tim/code/django/django/core/management/base.py", line 385,
in check
include_deployment_checks=include_deployment_checks,
File "/home/tim/code/django/django/core/management/commands/migrate.py",
line 61, in _run_checks
issues = run_checks(tags=[Tags.database])
File "/home/tim/code/django/django/core/checks/registry.py", line 81, in
run_checks
new_errors = check(app_configs=app_configs)
File "/home/tim/code/django/django/core/checks/database.py", line 9, in
check_database_backends
for conn in connections.all():
File "/home/tim/code/django/django/db/utils.py", line 226, in all
return [self[alias] for alias in self]
RecursionError: maximum recursion depth exceeded
}}}
The loss of a helpful message isn't desirable.
