26254	Support for disallowing filter on local fields in ModelAdmin	Dheerendra Rathor	nobody	"Currently, if a local field is not present in `list_filter` and filter is called on that particular field directly in URL, it is allowed to filter on that particular field. But, if filter is called on a relational field which is not present in `list_filter`, filter is disallowed on that particular field. 

This feature request is in support for disallowing filter on certain fields. This can be done by either not allowing filter on a field if field is not mentioned in `list_filter` or by adding an extra ModelAdmin field `disallowed_lookups`.  But disallowing on the basis of list_filter might break admin for sites heavily relying on admin, second option will be better in my opinion. 


{{{
# An example fix
if len(relation_parts) <= 1:
    # Either a local field filter, or no fields at all.
    if len(relation_parts) == 1 and relation_parts[0] in self.disallowed_lookups:
        return False
    return True
