上記２つのrequireをapplication.rbに記載しないと、rails sしたときに下記エラーが発生するuninitialized constant ::ActiveResource

Fix

add poems_path to routes.rb

Fix

add set_poem to update_action

before_action :set_poem, only: [:show, :edit, :destroy]
before_action :set_poem, only: [:show, :edit, :destroy, :update]

[Fix]Strong_params # Never trust parameters from the scary internet, only allow the white list through. def poem_params

params.require(:poem).permit(:content, :auther)

end

–> params.require(:poem).permit(:title, :content, :auther)

[Fix]routes.rb Rails.application.routes.draw do

resources :poems ,only: [:show, :update, :destroy, :edit, :new, :create]
root 'poems#index'

end

–> resources :poems ,only: [:index, :show, :update, :destroy, :edit, :new, :create]
