How to get a resource url in model

I have a simple posing app. How can I get a post url from it's model and pass it to Bitly shortener? (replace http://www.google.com with post url)

It's probably something like 

Rails.application.routes.url_helpers.posts_path(self...)

-

class TwitterWorker
  include Sidekiq::Worker

  def perform(title, url)
    tweet("#{title} #{url}")
  end
end

-

class Post < ActiveRecord::Base
  include Tweets
  extend FriendlyId

  after_create :post_to_twitter

.....

  private

  def post_to_twitter
    title = self.title[0..120]
    url = Bitly.client.shorten("http://www.google.com").short_url
    TwitterWorker.perform_async(title, url)
  end

end

-

I used to have this code in model

 # tweet("#{title[0..120]} #{ Bitly.client.shorten('http://www.google.com').short_url}")

UP I ended up doing the following.

Since I have a few models that can make postings, I slightly refactored post_to_tweeter meth

worker

class TwitterWorker
  include Sidekiq::Worker
  include Tweets
  include Rails.application.routes.url_helpers

  def perform(message, slug)
    url = Bitly.client.shorten(post_url(slug, host: ActionMailer::Base.default_url_options[:host])).short_url
    tweet("#{message} #{url}")
  end
end

model

after_create :post_to_twitter

def post_to_twitter
  message = "#{self.title[0..120]}"
  TwitterWorker.perform_async(message, self.slug)
end

If you're using the model IDs in the URL, you can use the code below. However, I like to use the obfuscate_id and/or friendly_id gems to prevent users from knowing how many records are in the database.

Model:

class Post < ActiveRecord::Base

...

private

  def post_to_twitter
    title = self.title[0..120]
    TwitterWorker.perform_async(title, self.id)
  end
end

Twitter Worker:

class TwitterWorker
  include Sidekiq::Worker

  def perform(title, post_id)
    tweet("#{title} Bitly.client.shorten(post_url(#{post_id})).short_url) 
  end
end

This will set the url to http://localhost.com/post/123 if 123 is the post id.

To set what your website is in staging and production enviroments, here's a quick read - How does rails 4 generate _url and _path helpers.

P.S. You can also use the post_url trick for including the absolute URLS in emails.

you can include the url helpers in models (though it normally is not the best way of dealing with things) 

class MyClass < ActiveRecord::Base
  include Rails.application.routes.   url_helpers
end
