我的目标是将所有凭据存储到config/secret.yml并将其从git中删除。
下面的配置在Mac OS X上按预期工作，但在Windows 7上会引发错误。
使用config / database.yml：
default: &default
adapter: postgresql
encoding: unicode
username: <%= Rails.application.secrets.database_username %>
password: <%= Rails.application.secrets.database_password %>
development:
<<: *default
database: project1_development
test:
<<: *default
database: project1_test
production:
<<: *default
database: project1_production
和config / secrets.yml：
development:
secret_key_base: d48527bc8072d6d84ebd037c2324f474af315459b2c7912f6e1e3abfb616e0f92cdca194845d4235b287f032345312d3aec870d391b603dd8d1a888185f7c642
database_username: postgres
database_password: test-test
test:
secret_key_base: d48527bc8072d6d84ebd037c2324f474af315459b2c7912f6e1e3abfb616e0f92cdca194845d4235b287f032345312d3aec870d391b603dd8d1a888185f7c642
