Using environment variables in controller (Rails) -

i'm trying display sendgrid email statistics inside rails application.

so far, i've been able display them in api's return format (e.g. [{"delivered"=>9, "unsubscribes"=>0, "repeat_bounces"=>2,....), that's if put plaintext username , password controller's private method because cannot seem use 'sendgrid_username' , 'sendgrid_password' environment variables. what's guy do?

in summation:

newsletterscontroller:

  before_action :set_client, only: :index  private      def set_client       @client = sendgridwebapi::client.new('the plaintext username', 'the plaintext password')     end 

newsletters index view

<p><%= @client.stats.get %></p> 

is there place can set @client view can , plaintext password can hidden outside world? preferably place can put in secrets.yml?

@client = sendgridwebapi::client.new('sendgrid_username', 'sendgrid_password') 

returns incorrect username , password, though got plaintext username , password i'm using testing from variables, know they're set correct ones.

or, there way use environment variables in either controller or view?

i'm able set variables in rails console , use them, since don't saved can't access them afterwords in actual application.

although solution not secrets.yml, works fine.

# config/initializers/my-supersecret-vars.rb env['sendgrid_username'] = 'my_super_secret_username' env['sendgrid_password'] = 'my_super_secret_password' 

just remember add on .gitignore
