get Error heroku when uploading image paperclip

Question

I installed the Paperclip gem into my rails app so I can enable users to upload pictures. Everything seems to be working fine locally. I then pushed to Heroku via the git push heroku master command line prompt and then proceeded to interact with my app live online. When I try to upload a picture and then click on the submit button, an error message appears.

Here are my logs (updated)

    validates_attachment :image, content_type: { content_type: ["image/jpg", "image/jpeg", "image/png", "image/gif"] }
end

db/migrate add_attached_image_to_pins.rb

class AddAttachmentImageToPins < ActiveRecord::Migration
  def self.up
    change_table :pins do |t|
      t.attachment :image

    end
  end

  def self.down
    drop_attached_file :pins, :image


  end
end

And finally the Gemfile

end

So far everything seemed to work until I started to interact with my app online through Heroku .

Here is my GitHub repo: https://github.com/cyzanfar/Photoshare

Thanks for any future help.

Answer 1

The actual error is here:

Paperclip::Error (Pin model missing required attr_accessor for 'image_file_name')

You need to add the Paperclip related columns like this to your Pin model:

rails generate paperclip Pin image

heroku run rake db:migrate

or create a migration file, example:

class AddAvatarColumnsToUsers < ActiveRecord::Migration
  def self.up
    add_attachment :users, :avatar
  end

  def self.down
    remove_attachment :users, :avatar
  end
end

You Pin model should also specify:

Class Pin < ActiveRecord::Base
  has_attached_file :image

Answer 2

DB

Here's your error:

Paperclip::Error (Pin model missing required attr_accessor for 'image_file_name'):

This is typically because you have either not included the has_attached_file helper in your paperclip model, or you have not performed the Paperclip migration

If it works in development, it will likely mean you have not got the db set up on Heroku - which can be fixed by using the following:

$ heroku run rake db:migrate
