ruby-on-rails - trouble returning profiles that have blocked you using amistad gem

Question

I am having trouble returning all profiles that have blocked you with the amistad gem.

I am able to find profiles you have blocked.

And the profiles other individual profiles have blocked.

a = Profile.find_by_id 6
b = Profile.find_by_id 7

b.block_profile a

a.blockades

  Profile Load (0.2ms)  SELECT ".."

 => #<ActiveRecord::Associations::CollectionProxy [#<Profile id: 18....>]>

a.blockades_by

  Profile Load (0.2ms)  SELECT "profiles".* FROM "profiles" INNER JOIN "friendships" ON "profiles"."id" = "friendships"."friendable_id" WHERE "friendships"."blocker_id" = ? AND (friendable_id <> blocker_id)  [["blocker_id", 6]]
 => #<ActiveRecord::Associations::CollectionProxy []>

 b.blockades
  Profile Load (0.2ms)  SELECT "...."
 => #<ActiveRecord::Associations::CollectionProxy [#<Profile id: 6,....>]>
Oky, so it works if you know which profile exactly to look at.

But the issue is I would need to iterate through every profile and look at their blockades_by to see if the logged in user is there, then remove them from the final query. This is way too crazy. There needs to be a simpler way?
