| # Enable class level code to lazily access database information. | |
| # Often ActiveRecord class definitions will rely upon the table schema | |
| # information. For example the following snippets would acquire a database | |
| # connection: | |
| # ignore_columns :foo | |
| # # or | |
| # attribute_names.each ... | |
| # This results in rails accessing the database when booting, resulting in | |
| # ridiculous behavior like this: | |
| # bin/rake db:setup |
