Why didn't change url in browser field? - ruby-on-rails

Question

I want to get in my browser url field like this:
/posts/title_post instead /posts/id
I have written:
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
bundle exec rake routes:
/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
Blog works, but url is post/5 (for example). How to make url like: 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

Try this ........
post_controller.rb:
Find will only work with params[:id]
def set_post
#post = Post.find(params[:id])
end
To find with title you need to use :
def set_post
#post = Post.find_by(title: params[:title])
end
Here, to make url like: post/my_post_title? there is a good Gem, You can also try this...
You need to use 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)
For more details please refer this link freindly_id gem
Hope this will work for you.
