You put the assert_latest around that code, and it will detect any new records of the given type. You can then assert the records have the fields you expect. The assertion is "polygamous" because you can pass any list of types in. The original version only took one type. This is useful for any kind of testing, but super-useful for integration tests, to detect large batches of new records. Get assert_latest with the assert_efficient_sql gem.

I'm creating my own custom language syntax for TextMate. In the bundle editor I'm setting up folding like this: foldingStartMarker = '^\S+.*$'; foldingStopMarker = '^\s*$'; This tells TextMate that the start of a foldable section is any non- empty line that isn't indented, and the end of a foldable section is an empty line. I'm trying to match the case where the line is not technically empty, but only contains whitespace (hence the \s* part of the regular expression). This does not work. The folding stop marker appears when the line is completely empty, but the moment I put spaces in the line, the folding stop marker goes away. Did I get the regular expressions wrong, is it a bug in TextMate, or is something else wrong? Thanks in advance!

Also take into account that in the typical multi-process setup there are as many interpreters running as processes, and thus those handlers are going to run those many times. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
