This gem currently is not supported, because of changes in google-api-ruby-client. There is working alternative for google-api-ruby-client with 0.8.0 version.
PaperclipGoogledrive is a gem that extends paperclip storage for Google Drive. Works with Rails 3.x.
Add this line to your application's Gemfile:
gem 'paperclip-googledrive'
And then execute:
$ bundle
Or install it yourself as:
$ gem install paperclip-googledrive
Google Drive is a free service for file storage files. In order to use this storage you need a Google (or Google Apps) user which will own the files, and a Google API client.
-
Go to the Google Developers console and create a new project.
-
Go to "APIs & Auth > APIs" and enable "Drive API". If you are getting an "Access Not Configured" error while uploading files, this is due to this API not being enabled.
-
Go to "APIs & Auth > Credentials" and create a new OAuth 2.0 Client ID; select "web application" type, specify
http://localhostfor application home page. -
Now you will have a Client ID, Client Secret, and Redirect URL.
-
Run the authorization task:
$ rake google_drive:authorizeWhen you call this Rake task, it will ask you to provide the client id, client secret, redirect url and auth scope. Specify
https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/userinfo.profilefor scope (more on Google Drive scopes). -
The Rake task will give you an auth url. Simply go to that url (while signed in as the designated uploads owner), authorize the app, then enter code from url in the console. The rake task will output valid ruby code which you can use to create a client, in particular, the access and refresh tokens.
-
Create a folder in which the files will be uploaded; note the folder's ID.
Example:
class Product < ActiveRecord::Base
has_attached_file :photo,
:storage => :google_drive,
:google_drive_credentials => "#{Rails.root}/config/google_drive.yml"
endThe :google_drive_credentials option
This can be a hash or path to a YAML file containing the keys listed in the example below. These are obtained from your Google Drive app settings and the authorization Rake task.
Example config/google_drive.yml:
application_name: MyApp
application_version: 1.0.0
client_id: <%= ENV["CLIENT_ID"] %>
client_secret: <%= ENV["CLIENT_SECRET"] %>
access_token: <%= ENV["ACCESS_TOKEN"] %>
refresh_token: <%= ENV["REFRESH_TOKEN"] %>It is good practice to not include the credentials directly in the YAML file. Instead you can set them in environment variables and embed them with ERB.
The :google_drive_options option
This is a hash containing any of the following options:
:path– block, works similarly to Paperclip's:pathoption:public_folder_id- id of folder that must be created in google drive and set public permissions on it:default_image- an image in Public folder that used for attachments if attachment is not present
The :path option should be a block that returns a path that the uploaded file should be saved to. The block yields the attachment style and is executed in the scope of the model instance. For example:
class Product < ActiveRecord::Base
has_attached_file :photo,
:storage => :google_drive,
:google_drive_credentials => "#{Rails.root}/config/google_drive.yml",
:styles => { :medium => "300x300" },
:google_drive_options => {
:path => proc { |style| "#{style}_#{id}_#{photo.original_filename}" }
}
endFor example, a new product is created with the ID of 14, and a some_photo.jpg as its photo. The following files would be saved to the Google Drive:
Public/14_some_photo.jpg Public/14_some_photo_medium.jpg
The another file is called some_photo_medium.jpg because style names (other than original) will always be appended to the filenames, for better management.
