Carrierwave Example Uploader

Steps

• Add gem 'carrierwave' to Gemfile
• Run bundle install to install the new gem
• Stop spring: spring stop
• Run rails generate uploader Image
• Mount the newly generated ImageUploader on your Model. I mounted it on the string type column image by adding this in my model's class:

class Product
  mount_uploader :image, ImageUploader
end

• In your Form view, add the option type: :file, e.g.:
  • form_for(@post, type: :file)
• Again in your Form view, change the type of your image field from f.text_field to f.file_field.
• Change all your image_tags to not use model.image, but model.image.url
  • NB: make sure to check if the image exists, or things will break! Example: <%= image_tag luxury_coffee.image.url if luxury_coffee.image.present? %>
• Add public/uploads to your .gitignore file.
