-------------------------------+--------------------
Including reverse one-to-one relations in `list_display` or `fields` in a
`ModelAdmin` breaks the "change_list" and "change" admin views.
The "change" view raises a `FieldError` saying the reverse one-to-one
field is unknown. The "change_list" raises `AttributeError`: 'OneToOneRel'
object has no attribute 'rel'.
I've setup a small test app here: https://gitlab.com/jerivas/one-to-one-
bug.
To reproduce:
- Clone the repo
- Install deps from requirements.txt
- Start the development server
- Visit the admin. User/pass: proj/proj
- Both the Car and Engine admins should work
- Uncomment lines 7 & 8 from `cars/admin.py`
- Both the "change_list" and "change" views of the Car admin are now
broken. The Engine admin continues to work as expected.
This worked normally in 1.6, and I just found it while updating a project
from 1.6 to 1.8. I don't know if the bug was introduced in 1.7 or 1.8.
