No reason why you can't instantiate the schema manager directly in the same way that the provider does.

Hi Rob

how can I use this tool not from command line, but in regular php script, is it possible?

I'm asking, because I want to add db migration functionality to pre_activate.php hook script(for update) and pre_rollback.php(for migrate to earlier db version), which runs during deployment to ZS/ZSCM.

So idea is just add Akrabat directory to library/ directory, and simple include necessary classes in pre_activate.php and pre_rollback.php and perform updating to necessary db version.

i just try using the cast hint on the first command, it also worked:

zf update-to database-schema (int)0

When you want to migrate to the first schema you can use this also

zf update-to database-schema 0

when asked again for a migrate version answer with (int) 0

Nice tool - I have to admit though I dont like the term "update" - I think it would be better to call it "migrate". Doing something like "update-to" when you really want to downgrade seems a bit weird.

@Wanderson & Rob
I happened upon the solution for the version 0 migration by accident. If you make the revision portion of the command a character, it will convert to the integer 0, therefore sending you all the way back to revision 0. It was unfortunate to find the hack the way I did, but it works :P I was trying to goto revision 3 and instead went to revision "e" because I fat fingered my keyboard.

Hi Rob

Great stuff!

I'm seeing the same response as Wanderson when running:

$ zf update-to database-schema 0

There doesn't seem to be a way to run the down method on the first migration?

Cheers
Bruce

Good catches - I've updated and pushed.

Thanks!

Also,

Your version is an int, so we can't use 201012140001 as a version number. I manually changed it to a bigint field and it seems to work they way I want/need. I really like the idea of the version being a date.

The new version of the tool seems to require a prefix. If you don't want one, it prefixes with an _.

Here's a diff
