Here’s a patch for line 135 that makes it not barf if you put base data, SQL scripts, etc. in the db/migrate directory. This matches only files, and only files starting with a digit and ending with .rb:

unless File.directory?(file) || (! file.match(/\d+_.*\.rb/)) || SKIPPED_FILES.include?(file)

thanks for sharing the script. Worked perfectly though i didn’t try the –svn option. Instead I ran it as shell and did a manual commit on the resulting files.

It turns out that `svn rename` doesn’t actually rename the file. It’s an ADD followed by a DELETE of the original file. So performing a `svn rename` on a large migration files move-around can result in devastating consequence to your team.

You’ve been warned.

Once you move migration using –svn, you have to explicitly commit it to the repository. Otherwise you will get complaints about the file doesn’t exist in the repository or something.

Another prerequisite to run numergrate with –svn option is you have to have Subversion client installed (svn.exe on Windows, included in the full Subversion installation, not the TortoiseSVN installation). Otherwise nothing will happen, even though you will see messages printed out to the screen.
