How can I generate a link to the ID of a profile?

I have two controllers- a ProfilesController and a UsersController. I have a page full of blog posts, and I want each to have a link to the profile of the user who created them. I've been having a wee problem with this lately, and I want to start fresh, but don't know where to begin. How can I go about this?

Post controller:

 def index
  if params[:search]
    @posts = Post.search(params[:search]).order("created_at DESC").paginate(page: params[:page], per_page: 5)
  else
    @posts = Post.all.order('created_at DESC').paginate(page: params[:page], per_page: 5)
  end
 end

Profiles model:

class Profile < ApplicationRecord
  belongs_to :user
end

Users model:

class User < ApplicationRecord
  has_secure_password
  validates :username, uniqueness: true
  has_many :posts, foreign_key: :author
  has_many :comments, foreign_key: :author
  has_one :profile, foreign_key: :user

  after_create :build_profile

  def build_profile
    Profile.create(user: self) # Associations must be defined correctly for this syntax, avoids using ID's directly.
  end

end

BTW not using Devise

How are your SQL tables? It would be best if your Posts table have a user_id field, that way you could search the user by id (user_id) and process the link via:

<%= link_to 'Post Owner', user_path(post.user_id) %>

Check to see if it works for you and let me know.

Firstly, We get object profile of each posts like this (you should try it in rails console):

@posts.first.user.profile # get the profile of first post

After that, we use profile_path to generate link to profiles#show (Of course, you need to define a controller Profile)

profile_path(@posts.first.user.profile)

I often do it in view, not in controller.

Happy coding!
