I am developping a web app and I've wrote some admin
code (parsing web site, sending massmail etc...) which don't
need to be deployed. So I would like this code to be part of
a second developement app.
Interesting. What leads you to want to separate the admin functionality
into a completely separate app?
But there's a probleme regarding the schema_migrations table.
it must be unique.
How can I solve this problem?
The easiest way I can think of would be to simply run all your migrations
from one of the apps. As long as you never run any migrations from the
second app I can't think of any way you'd run into conflicts. Doesn't mean
you won't. Just that I can't think of any off the top of my head
