Thanks, I implemented a similar fix that addresses this issue.
from django-natural-keys.
Exploded version that seems to work for me:
def natural_key(self):
"""See https://github.com/wq/django-natural-keys/issues/18."""
vals = []
for name_list in [name.split("__") for name in self.get_natural_key_fields()]:
val = self
for attr_name in name_list:
val = getattr(val, attr_name)
if val is None:
break
vals.append(val)
return vals
>>> Job.get_natural_key_fields()
['source', 'git_repository__name', 'module_name', 'job_class_name']
>>> Job.objects.first().git_repository # None
>>> Job.objects.first().natural_key()
['plugins', None, 'example_plugin.jobs', 'ExampleHiddenJob']
>>> Job.objects.get_by_natural_key('plugins', None, 'example_plugin.jobs', 'ExampleHiddenJob')
<Job: Example hidden job>
