Docs for MyModel._meta.get_fields_with_model() missing info about 'is_relation'

Description

​https://docs.djangoproject.com/en/1.9/ref/models/meta/#migrating-old-meta-api

Docs use source code a explanation:

MyModel._meta.get_fields_with_model():

[
    (f, f.model if f.model != MyModel else None)
    for f in MyModel._meta.get_fields()
    if not f.is_relation
        or f.one_to_one
        or (f.many_to_one and f.related_model)
]

1) Why does get_fields_with_model return fields with not is_relation?

2) When does a many_to_one field not have a related_model?

3) Is it possible to have a one_to_one field with no related_model?

  1. This excludes non-relational fields I believe.
  2. GenericForeignKey I think.
  3. I don't think so.

Feel free to submit a patch if you are able.

What these attributes mean and when they're set is documented in the ​Field attribute reference.
