Accessing the AppConfig object

After installing this plugin, the AppConfig object will be global available. Entries are accessed via object member notation:

 AppConfig.my_config_entry

Nested entries are supported:

 AppConfig.my_section.some_entry

Common config file

Config entries defined in

 RAILS_ROOT/config/app_config.yml

will be available to all environments.

Environment specific config files

You can have environment specific config files. Environment specific config entries take precedence over common config entries.

Example development environment config file:

 RAILS_ROOT/config/environments/development.yml

Example production environment config file:

 RAILS_ROOT/config/environments/production.yml

Embedded Ruby (ERB)

 Embedded Ruby is allowed in the configuration files.  See examples below.

Examples

Consider the two following config files.

RAILS_ROOT/config/app_config.yml:

 size: 1
 server: google.com

RAILS_ROOT/config/environments/development.yml:

 size: 2
 computed: <%= 1 + 2 + 3 %>
 section:
   size: 3
   servers: [ {name: yahoo.com}, {name: amazon.com} ]

Notice that the environment specific config entries overwrite the common entries.

 AppConfig.size -> 2
 AppConfig.server -> google.com

Notice the embedded Ruby.

 AppConfig.computed -> 6

Notice that object member notation is maintained even in nested entries.

 AppConfig.section.size -> 3

Notice array notation and object member notation is maintained.

 AppConfig.section.servers[0].name -> yahoo.com
 AppConfig.section.servers[1].name -> amazon.com
