Почему не изменился URL-адрес в поле браузера?

Question

Я хочу, чтобы в моем браузере поле URL-адрес, как это:

/posts/title_post instead /posts/id 

Я написал:

routes.rb:

# added param: :title 
resources :posts, param: :title do 
    resources :comments, only: [:new, :create] 

resources :images do 
    resources :comments, only: [:new, :create] 
end 

resources :links do 
    resources :comments, only: [:new, :create] 
end 
resources :photos, only: [:new, :create,:destroy] 
resources :songs, only: [:new, :create, :destroy] 
end 

расслоение Exec рейк маршруты:

/posts/new(.:format)   posts#new 
/posts/:title/edit(.:format) posts#edit 
/posts/:title(.:format)   posts#show 
/posts/:title(.:format)   posts#update 
/posts/:title(.:format)   posts#update 
/posts/:title(.:format)   posts#destroy 

post_controller.rb:

def set_post 
    @post = Post.find(params[:title]) 
end 

Блог работает, но Ссылка на пост/5 (к примеру). Как сделать url как: post/my_post_title?

class PostsController < ApplicationController 

    before_action :authenticate_user!, only: [:new, :create, :show] 
    respond_to :html, :json, :rss, :atom 
    def index 
    if params[:search].blank? 
     @posts = Post.includes(:comments, :photos).all 
    else 
     @search = Post.search do 
     fulltext params[:search] 
     end 
     @posts = @search.results 
    end 
    respond_with(@posts) 
    end 

    def show 
    set_post 
    end 

    def new 
    @post = Post.new 
    end 

    def edit 
    set_post 
    end 

    def create 
    @post = Post.new(post_params) 
    # responder gem doc 
    @post.errors.add(:base, :invalid) unless @post.save#test 
    respond_with(@post) 
    end 

    def update 
    set_post 
    if @post.valid? 
     @post.update(post_params) 
    else 
     # responder gem doc 
     @post.errors.add(:base, :invalid) 
    end 
    respond_with(@post) 
    end 

    def destroy 
    set_post 
    @post.destroy 
    respond_with(@post) 
    end 

    def feed 
    @posts = Post.all.reverse 
    respond_with(@posts) 
    end 

    def archive 
    @posts_by_year = Post.limit(300).all.order("created_at DESC"). 
    group_by {|post| post.created_at.beginning_of_year} 
    end 

    private 

    def set_post 
    @post = Post.find(params[:title]) 
    end 


    def post_params 
    params.require(:post).permit(:title, :content) 
    end 
end

Попробуйте это ........

post_controller.rb:

поиск будет работать только с Params [: id]

def set_post 
    @post = Post.find(params[:id]) 
end 

Для поиска с названием вам нужно использовать:

def set_post 
    @post = Post.find_by(title: params[:title]) 
end 

Здесь, чтобы сделать URL, как: пост/my_post_title? есть хороший Gem, Вы также можете попробовать это ...

Вы должны использовать FriendlyId gem

# Gemfile 
gem 'friendly_id' 

rails generate friendly_id  
rake db:migrate 

# edit app/models/post.rb 
class Post < ActiveRecord::Base 
    extend FriendlyId 
    friendly_id :title_post, use: :slugged 
end 

# If you're adding FriendlyId to an existing app and need 
# to generate slugs for existing users, do this from the 
# console, runner, or add a Rake task: 
Post.find_each(&:save) 

Для получения более подробной информации, пожалуйста, смотрите эту ссылку freindly_id gem

Надеется, что это будет работать для вас.
