Ruby on Rails

I think you can use rolify as you have dynamic permissions.

 I have a problem with the implementation of the search in the project


I have such models(bring a simplified version)

User
   id
   name

Friends
   user_id
   friend_id

Post
  id
  title
  author_id
  is_public

PostDeniedUser
   post_id
   user_id

some explanations:

User can create post. Post can be public or private. If post private only friends of author can see it post, but author can denied access to some friends.

I need to implement search Post by title considering visibility for each user.

some explanations:

User can search in all public posts, in private posts of his friends which are not denied in one query.

I think create some model SearchPost and like NewsFeed.
duplicate all the data on posts for each user, taking into account the availability of, and then just make an inquiry with the search by title by authorized users
