Tell me how to build a connection between the models as follows:
- User can have many posts
- Different users can write posts to each other on the wall (as in social networks, namely when you can create an entry yourself or another user can create it on your page.

    User Model:

    # models/user.rb class User < ApplicationRecord has_many :posts has_one :wall end

    Post model:

     # models/post.rb class Post < ApplicationRecord belongs_to :posts belongs_to :wall end

    Model wall / blog, etc.:

     # models/wall.rb class Wall < ApplicationRecord has_many :posts belongs_to :user end

    Thus, you can create entries that will have an author and which will be tied to a specific wall. The request for wall entries will look like this:

     @posts = Wall.find(wall_id).posts

    Request for specific user records:

     @user_posts = Wall.find(wall_id).posts.where(user: @user)

    To get the wall of a particular user:

     @wall = @user.wall

    To get entries from the wall of a particular user:

     @posts = @user.wall.posts

    To get wall owner records:

     @owner_posts = @user.wall.posts.where(user: @user)
