设置新的Rails环境变量

Question

This is probably a easy question but cant seem to find a straight answer. I'm trying to set up a mailer and config the smtp settings and I was wondering how do you set new environment variables for

:user_name      => ENV['GMAIL_USERNAME'],
:password       => ENV['GMAIL_PASSWORD']

Thanks for the help.

Answer 1

You can set them up and keep them secret using the Figaro Gem

Add it to your Gemfile and bundle . Then install Figaro:

bundle exec figaro install

Once it's installed, you'll have a new file called application.yml in your config folder

You can create environment variables there and they're ignored by Git so your secrets won't get published.

You can set different variables for different environments if you want.

development:
  GMAIL_USERNAME: 'yourname@gmail.com'
  GMAIL_PASSWORD: notaRE41p4ssw0rD

production:
  GMAIL_USERNAME: 'yourproductionname@gmail.com'
  GMAIL_PASSWORD: notaRE41p4ssw0rD317h3R

To push them to Heroku:

$ figaro heroku:set -e production

Answer 2

Have a look at the dotenv gem as well. Figaro seems to be poorly maintained at the moment.

Answer 3

Another option beside accepted answer, for heroku setting environment variabel can be setup using heroku terminal command as follow

heroku config:set GMAIL_USERNAME=******* 
heroku config:set GMAIL_PASSWORD=******
