embedded ruby in database.yml config file

rubyonrails-talk

I have noticed in Rails 4.2 the following in rails console

#database.yml … development: <<: *default database: project_development username: root password: <%= ENV[‘PASSWORD’] %>

development_replica: <<: *default database: replicat_db username: replica_user password: <%= ENV[‘REPLICA_PASSWORD’] %>

``

If I look at ActiveRecord::Base.configurations[‘development’] the password set

If I look at ActiveRecord::Base.configurations[‘development_replicate’] the password is nil

This happens with any embedded ruby that is not in the Rails.env configuration block.

Is this expected behaviour?

To establish another connection I am supposed to do the following but the embedded ruby isn’t evaled ActiveRecord::Base.establish_connection(:development_replica)

``

Advice or thoughts?

Thanks

The erb step happens before YAML parsing so that sounds unlikely. Are you sure that environment variable is set.

I’ve decided to use dotenv-rails and this seems to have remedied things. Perhaps it was an eval order issue.

I did have ENV populated with all values I expected to see, they just weren’t in the configurations.

Thanks

So I worked out that Spring was my problem. If the ENV[‘DATABASE_URL’] or any other setting is not set then Spring still starts and keeps running with things unset.

I lost far too much time wondering why I could see my ENV variables in Rails Console but database.yml wasn’t getting set.
