In this lesson, we are going to integrate the uploader into our ActiveRecord model because even though we already created an uploader for the application, the model file does not know that it exists.
To do that, go to the model file post.rb and put this code in:
mount_uploader :image, PhotoUploader
In this code, we are asking the application to mount the uploader and the database attribute that we want to upload is image. We are also calling the PhotoUploader because that's the class related to the uploading process.
So, that's how you integrate the uploader.
