git, submodules and Capistrano

If you use git submodules, as git-rails does, and want to use Capistano, you’ll need to patch patch Capistrano (lib/capistano/recipes/deploy/scm/git.rb) to make sure your submodules get included.

        def checkout(revision, destination)
          git      = command

          branch   = head

          fail "No branch specified, use for example 'set :branch, \"origin/master\"' in your deploy.rb" unless branch

          if depth = configuration[:git_shallow_clone]
            execute  = "#{git} clone --depth #{depth} #{configuration[:repository]} #{destination} && "
          else
            execute  = "#{git} clone #{configuration[:repository]} #{destination} && "
          end

          execute += "cd #{destination} && #{git} checkout -b deploy #{branch}"

          if submodules = configuration[:git_enable_submodules]
            execute += " && git-submodule init &&"
            execute += "git-submodule update"
          end

          execute
        end

then define this in your deploy.rb:

set :git_enable_submodules,1

Or you can use the trunk version (post 2.1), which includes that support already.
