Sometimes you have some fixutres want to load them into some db by hand, maybe as useful data. You can do this by rails console:

$ script/console
>> table = YAML.load_file("#{table_name}.yml")
>> ActiveRecord::Base.transaction do
>> table.each do |fixture_name, fixture|
>> ActiveRecord::Base.connection.execute "INSERT INTO #{table_name} (#{fixture.keys.join(",")}) VALUES (#{fixture.values.collect {|value|  ActiveRecord::Base.connection.quote(value) }.join(",")})", "Fixture Insert"
>> end
>> end
