Where to set stripe API key in rails application?

Question

I currently have this in every controller action that needs it (quite a few):

Stripe.api_key = Rails.application.credentials[Rails.env.to_sym][:stripe][:secret_stripe_test_key]

Where is the best place to put this code? The options that come to mind are:

• Leave it where it is in each of the controller actions that need it
• Place it in a before_action, and run that before the controller actions that need it
• Place it in a application helper and run it from inside controller actions that need it
• Place it in an initializer.rb file and have it run once on the application start

What I currently have isn't DRY, so I figured there's got to be a better way.

Answer 1

I prefer the approach mentioned here Stripe on Ruby on Rails - Creating config/initializers/stripe.rb You can then have the values in environment variables. This is safer when in production

Answer 2

You can create an intializer file inside folder config/initializers/stripe.rb and put this key there

Stripe.api_key = Rails.application.credentials.stripe_secret_key
