Capistrano rails app deployment without DB

[MrBa...@googlemail.com]

Hello everyone,

I m an absolutely rookie ...I ve installed some days ago capistrano
via gems and I ve tried to setup my deployment with capistrano for my
little rails application.

Everything works fine so far, but unfortunetly, I am using a legacy
database and therefore cannot use the rails db migration feature.

My question is how to tell capistrano in my config file that he should
not run any db task?

I tried to remove the role :db ... line
I set role:db, ""
role:db, nil

However, the cold_deploy was nt able to finish without an error...

Any ideas?

Thanks a lot in advance

Well, depends, for role:db, nil undefined method `match' for
nil:NilClass
for role:db, "" connection failed for: (Errno::EBADF: Bad file
descriptor - connect(2))
When removing the whole line... I get an no db role defined error.

If you are using the deploy:cold task, if expects to run migrations
and thus needs a db role. What you want is to not define a db role at
all, and then run parts of the deploy:cold task that you want,
manually, e.g.:

cap deploy:update deploy:start

You could, of course, override the deploy:cold task to suit your own
needs:

deploy.task :cold do
deploy.update
deploy.start
end

What exactly are all the parts of the deploy:cold task?
Are they just deploy:update and deploy:start?
