How to show table from other controller?

I've got two controllers (Users, Posts) with two tables, but I need to pull all the posts from Posts table posted by User.id No matter what I did, I receive NoMethodError in Users#show

user_controller.rb:

class UsersController < ApplicationController 
  before_action :set_user, only: [:show, :edit, :update, :destroy]

  def index 
    @users = User.all 
    @posts = Post.all 
  end
  def show 
    @posts = Post.all 
  end
end

How do you people usually show table from other controller in another controller?

Full error:

NoMethodError in Users#show

Showing ~/users/show.html.haml where line #37 raised:
undefined method `first' for nil:NilClass
Extracted source (around line #37):

35 %p
36 %b TEST:
37 = @post.first

if you want "all the posts from Posts table posted by User.id', replace @posts = Post.all for @posts = @user.posts on #show method

@post.first this code raises the exception. You defined @posts not @post!
