Unable to use search_select_filter on collections

[heaven]

For example, with has_many :tags, which yields:

undefined method `tags_eq' for #<Ransack::Search:0x00007f9056792668>

And selected_list_filter doesn't exist.

search_select_filter is used with belongs_to associations.

@ldlsegovia yep but there's no alternative for collections it seems.

This is happening to me even though the model has belongs_to for the model I'm trying to build a filter for.....
