Debug Output For Migrations in Ruby on Rails
Posted by Ben Reubenstein Tue, 31 Jul 2007 13:04:00 GMT
Today I was doing some massive migrations that rocked the very foundations of an app I am working on. Problem was that during the migration I was moving objects around the database and validations were failing for my saves. To get some debugging going, I started out trying to write to the logger, with some good ol' logger.debug, but that does not work within a migration. To output information in a migration, use puts. So for example to see all the errors that prevented object g from being saved:class MyMigration < ActiveRecord::Migration
def self.up
g = G.new(:name => "name" )
if g.save
#More object manipulation here
else
g.errors.each do |x|
puts x
end
end
end
def self.down
#Down Method Code Here
end
end
What a nerd. U rock!
You rule! Good old fashioned terminal dump debugging! Thank you very much!
