The Rename refactoring lets you change the following names:
Files and directories
Methods and its parameters
Components of Rails applications
Rails named scopes
RubyMine automatically changes all the references to renamed items throughout code.
Renaming local variables or private methods can be done easily in-line since only the limited scope is affected. Renaming classes or public methods could potentially impact a lot of files. In this case, we suggest that you preview potential changes before you refactor.
The procedure below demonstrates how to rename a class method.
Place a caret at the method name:
Press Shift+F6 or selectfrom the main menu.
Specify a new method name in the invoked dialog and click Refactor:
In the Refactoring Preview window, inspect code changes to be made and click Do Refactor:
