Question

I’m trying to work on a Rails site here in it’s development environment, where I want to test email delivery, and I can’t work out why properties declared in the main environment.rb aren’t being overwritten by the more specific development.rb file that I presume would be loaded when booting a rails app.

My understanding here is that values in more specific environment config files like this should override the shared ‘environment.rb’ config file, so if I have declared some email settings like so in config/environment.rb…

ActionMailer::Base.smtp_settings = {
  :address        => 'smtp.hostingcompany.com',
  :port           => 25,
  :domain         => 'productiondomain.net',
  :authentication => :login,
  :user_name      => "productiondomainmailer",
  :password       => "TOP_SEKRIT"
}

… then code here in config/environments/development.rb below should override the ActionMailer:Base.smtp_settings hash:

ActionMailer::Base.smtp_settings = {
  :domain         => 'developmentdomain.net'
}

However, when load the app in the development environment, or from script/console to check the value of ActionMailer::Base.smtp_settings[:domain], it’s still listed as ‘productiondomain.net’.

Why might this happening?

To set the configuration for your development environment put:

config.action_mailer.smtp_settings =

rather than:

ActionMailer::Base.smtp_settings =

in config/environments/development.rb

Note that in config/environments/development.rb you will need to specify the full set of settings and not just :domain as the hash overwrites the existing value rather than being merged with it.

And similarly, set the default in config/environments.rb by putting config.action_mailer.smtp_settings = inside the Rails::Initializer.run do |config| block.
