This method is deprecated or moved on the latest stable version. The last existing version (v1.2.6) is shown here.

These similar methods exist in v6.1.7.7:

to_prepare(identifier = nil, &block) public

Add a preparation callback. Preparation callbacks are run before every request in development mode, and before the first request in production mode.

An optional identifier may be supplied for the callback. If provided, to_prepare may be called again with the same identifier to replace the existing callback. Passing an identifier is a suggested practice if the code adding a preparation block may be reloaded.
