What I'm aiming for is a checkbox option in the list_display of the admin which will accept only selected checkbox (essentially a radiobox) and deselct the others.
The model field is not a ForeignKey.
Alternatively is there a way to do this in the model object list as one of the fields?
The example is of an image bank from which the client can choose a suitable photo for the current content. The client can also upload images.
Thanks, any pointers would be appreciated.
