Passing ActiveRecord Relation object to params?

In my controller code, under :index action, I have this sample code
@obj = UserSource.select('user.source_categories.code as category_code,
user.source_categories.name as category_name,
count(*)')
.merge(@sourced_user)
.joins(:table_1, :table_2)
.group(1, 2)
.reorder(count: :desc)

In the Index view, everything is working as expected, it is showing the data stored in @obj. Now in the Index view, I would like to have a "link_to 'category_code', some_path, remote: true", which would direct me to another action of the same controller via AJAX call but at the same time I would like to pass in the @obj, which is an ActiveRecord relation object as one of the params. I need the @obj to further process data once in the other action, and if possible the @obj needs to be maintained as ActiveRecord relation object type. Is it possible to pass ActiveRecord relation object from one action to another action?
