Re: Re: rake db:migrate script in Jruby

We have multiple rails apps that share teh models directory (sym links).

Our strategy was : Create on migration that build all the tables before we deployed.
Once we deployed (which we now are)
Migration is managed under a change control process in which we run manual mysql scripts to do the migration (after extensive testing of course)

What's the ideal solution? HTTP action? A remote console?

is there a way to turn the rake db:migrate into a text output of mysql
command to capture in a deploy script ?

Hi,

we’ve struggled the same problem in Virgo, and I’ve come up with a
solution.
Check out GitHub - virgosystems/jrecipes: Capistrano recipes for deploying a JRuby application. It has no
documentation yet, so here’s the deploy script I use with it:
http://pastie.org/400758 This has some additional goodness for copying
static files over and linking shared directories.

JRecipes introduces a new deploy strategy :war_file which builds a war
from
your application locally and puts it into your release_path. For
application
server it supports tomcat and takes care of restarting it and copying
your
war file into the webapps directory. I would welcome if someone with
experience with other app servers forked the project and implemented
support
for that.

Cheers,
LacKac
