投稿データとユーザー情報の結びつけ方法

Posted at

まず用意したのはpost.rb(models/post)

class Post < ApplicationRecord

  def user
    return User.find_by(id: self.user_id)
  end

end

そしてposts_controller

def show
@post = Post.find_by(id: params[:id])
@user = @post.user
end

・ポイント

post(投稿)のところにuserインスタンスメソッドを用意してあげる。

そしてposts_controllerの処理したいアクションにさっき用意したuserのインスタンスメソッドを入れてあげる。
