How to load environment variables in the Rails console?

Question

I think this is a little, easy question!

I'm using .env file to keep all my environment variables, and i'm using foreman.

Unfortunately, these environment variables are not being loaded when running rails console rails c so, i'm now loading them manually after running the console, which is not the best way.

I'd like to know if there any better way for that.

About a year ago, the "run" command was added to foreman

ref: https://github.com/ddollar/foreman/pull/121

You can use it as follow:

foreman run rails console

or

foreman run rake db:migrate

rails does not know about the environmental variables specified in .env file as it is specific to foreman. You need to set the environment explicitly before invoking rails console. Have a look at this question.

I personnaly use dotenv in development and testing environements. With this approach, you don't have to prefix your commands, just call the initializer in your config/application.rb :

Bundler.require(*Rails.groups)

Dotenv::Railtie.load

HOSTNAME = ENV['HOSTNAME']
