Rails - Jan 2006 - switchtower custom tasks question.

hi,

i''m just getting started using switchtower for deployment. i''m
working
with a small team of 3 and a hosted subversion repository.

i have switchtower working, but i need to create two custom tasks and
have those tasks run at deployment. 1) copy a working dispatch.fcgi
from another folder, and 2) copy db/database.example to
db/database.yml

here is what i''ve tried, inside of deploy.rb:

# custom tasks
desc "copy another dispatch.fcgi, which gets deleted"
task :cp_dispatch_fcgi do
  File.copy("/path/to/other_app/public_html/dispatch.fcgi",
"/path/to/current/public/dispatch.fcgi")
end

desc "copy database.example to database.yaml"
task :cp_database_yaml do
  put(File.read(''/path/to/current/db/database.example''),
"/path/to/current/db/database.yml", :mode => 0444)
end

and then:

desc "deploy"
task :deploy do
  transaction do
    update_code
    update_current
    cp_dispatch_fcgi
    cp_database_yaml
  end
end

i may be going about this all wrong, so any help would be appreciated.

thanks in advance, ian

Ian,

The easiest way is to take advantage of ST''s ability to hook into an  
existing task. If you define a new task and give it the same name as  
an existing task, prefixed with "before_" or "after_", ST
will
execute that task either before or after its namesake.

An example:

   task :after_update_code do
     cp_dispatch_fcgi
     cp_database_yml
   end

That way, you don''t have to duplicate the existing :deploy task just  
to add your custom functionality to it.
