[RUBY] How to prevent direct URL typing in Rails


Even if I made a conditional branch in the view file, I noticed that if it was hit directly from the Url, it would jump to the page.


Use before_action on any controller to create a conditional branch before taking an action.



class ItemsController < ApplicationController
  #before_Use action to make a conditional branch before jumping to the controller's action
  before_action :correct_user, only: [:edit]
  before_action :item_find, only: [:show, :edit, :update, :destroy]
  def edit


  def item_params
    params.require(:item).permit(:title, :explain, :category_id, :condition_id, :price, :delivery_fee_id, :prefecture_id, :delivery_date_id, :image).merge(user_id: current_user.id)
# before_Users are selected by the method with action
  def correct_user
    @item = Item.find(params[:id])
    if user_signed_in? && @item.user == current_user
      render :edit
      redirect_to root_path


If you hit the Url directly, you will always be asked to disclose the page to the controller via routing, so you need to describe it in the controller. I was able to reconfirm the flow of MVC once again.
