17985	Document ModelAdmin.lookup_allowed()	3point2	Simon Meers	"Right now, as a result of the security fix introduced in r15031, the only way to allow querystring lookups across relationships in the admin is to whitelist them by including them in list_filter.

However, in my application the lookup that needs to be whitelisted generates a huge filter widget as it contains thousands of instances.

It would be helpful if I could whitelist the exact lookup I need to link to without having to generate the filter widget itself.

Something like
{{{
class MyModelAdmin(ModelAdmin):
allow_lookup = [""fieldname__id__exact""]
}}}

would do. If the developers agree this is useful functionality, I could write a patch."	New feature	closed	Documentation	1.4	Normal	fixed		lemaire.adrien@… zborboa@…	Accepted	1	0	0	0	0	0
