Cloudinary is a cloud service that offers a solution to a web application's entire image management pipeline.
- Easily upload images to the cloud.
- Automatically perform smart image resizing, cropping and conversion without installing any complex software.
- Images are seamlessly delivered through a fast CDN, and much much more.
Add this line to your application's Gemfile:
gem 'alchemy_cloudinary', github: 'AlchemyCMS/alchemy_cloudinary'
And then execute:
$ bundle
Or install it yourself as:
$ gem install alchemy_cloudinary
To use the Cloudinary Ruby on Rails library, you have to configure at least:
cloud_name
api_key
api_secret
Setting the configuration parameters can be done by:
-
programmatically in each call to a Cloudinary method
-
globally using config/cloudinary.yml configuration file
Warning: In this case you must exclude it from version control system (git, etc). In
.gitignore
you can addconfig/cloudinary.yml
-
use a Rails initializer file.
You can place a file named
cloudinary.rb
in theconfig/initializers
folder of your Rails project.Here's some sample initializer code:
# config/initializer/cloudinary.rb Cloudinary.config do |config| config.cloud_name = 'sample' config.api_key = '874837483274837' config.api_secret = 'a676b67565c6767a6767d6767f676fe1' config.secure = true config.cdn_subdomain = true end
-
dynamically configure the
cloud_name
,api_key
, andapi_secret
by defining theCLOUDINARY_URL
environment variable.The configuration URL is available in the Management Console's dashboard of your account. When using Cloudinary through a PaaS add-on (e.g., Heroku), this environment variable is automatically defined in your deployment environment.
Here's a sample value:
CLOUDINARY_URL=cloudinary://874837483274837:a676b67565c6767a6767d6767f676fe1@sample
Note: If you use more than one configuration option, the order of precedence is:
CLOUDINARY_URL
->cloud_name
->cloudinary.yml
