Embedded ruby in database.yml config file

Rails
1

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.

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.
