admin: implementing list_prefetch_related

[Riccardo Magliocchetti]

Hello,

the need to list an m2m relationship serialized in the admin list view happens
quite often to me and overriding the queryset may not be as trivial as a
ModelAdmin attribute. It makes sense to me to match what is possible with
foreign keys and list_select_related.
Any opinion on implementing list_prefetch_related for ModelAdmin?

Hi Richard,

Overriding the queryset is a pretty simple method override, I'm not sure there is sufficient need for prefetching here. In particular, the syntax for prefetch related is much more complex than for select related, so it's less well suited to this kind of shortcut.

Hi Marc,

fine, was thinking on supporting just the simple case without the Prefetch object.
