为什么我得到两个不同的网址同样的＃34;故事＆＃34;在我的rails应用程序？

Question

我最近为正在开发的应用程序的用户创建了一个配置文件页面，但在此过程中我注意到该故事的URL最初与用户页面上的相同故事略有不同。例如，普通网址是＆＃34; http://localhost:3000/genres/action/stories/37＆＃34;虽然它是＆＃34; http://localhost:3000/genres/absurdist/stories/37＆＃34;同时故事最初属于＆＃34;动作类型＆＃34;而不是＆＃34;荒诞的＆＃34;。同时，这两个网址指向正常的故事页面。

genre.rb

class Genre < ApplicationRecord
  belongs_to :user
  has_many :stories, dependent: :destroy

  is_impressionable

  extend FriendlyId
  friendly_id :name, use: :slugged

  def should_generate_new_friendly_id?
    name_changed?
  end
end

story.rb

class Story < ApplicationRecord
  belongs_to :genre
  belongs_to :user
  has_many :episodes, dependent: :destroy

  is_impressionable

  extend FriendlyId
  friendly_id :title, use: :slugged

  def should_generate_new_friendly_id?
    title_changed?
  end

  has_attached_file :image, size: { less_than: 1.megabyte }, styles: { medium: "300x300#", wide: "200x400#" }
  validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/

  scope :of_followed_users, -> (following_users) { where user_id: following_users }
end

profiles_controller

class ProfilesController < ApplicationController
  before_action :find_user
  before_action :find_genre
  before_action :owned_profile, only: [:edit, :update]
  before_action :authenticate_user!

  def show
    @stories = User.find_by(user_name: params[:user_name]).stories.order('created_at DESC')
    impressionist(@user)
  end

  def edit
  end

  def update
    if @user.update(profile_params)
      flash[:success] = 'Your profile has been updated.'
      redirect_to profile_path(@user.user_name)
    else
      @user.errors.full_messages
      flash[:error] = @user.errors.full_messages
      render :edit
    end
  end

  private

  def profile_params
    params.require(:user).permit(:avatar, :bio)
  end

  def find_user
    @user = User.find_by(user_name: params[:user_name])
  end

  def find_genre
    @genre = Genre.friendly.find_by(params[:slug])
  end

  def owned_profile
    @user = User.find_by(user_name: params[:user_name])
    unless current_user == @user
      flash[:alert] = "That profile does not belong to you"
      redirect_to root_path
    end
  end
end
