# Rails Migration Export Panel

#### Migration file name

This option allows you to choose the default file name when exporting rails migrations. This is the file name that appears in the save sheet before you edit it. You always have final control over the file name of the migration.

- Name only This option gives you a default file name that consists of the document file name modified to meet Ruby class naming requirements
- Timestamp and Name This option gives you a Rails 2.x style timestamp and file name default. e.g 20100101_file.rb
- Default Revision and Name This option gives you the default revision (initally 1) and a valid file name. e.g 1_file.rb

#### Rename underscores with Rails Export

This option causes underscores in table names to be removed during export.
