Capistrano ignoring schema.rb?

i am deploying my stuff with capistrano and somehow the schema.rb is
always deployed empty … but in svn its full…
could someone explain me how capistrano handles the schema.rb?

when i deploy there is only this inside:

This file is autogenerated. Instead of editing this file, please use

the

migrations feature of ActiveRecord to incrementally modify your

database, and

then regenerate this schema definition.

ActiveRecord::Schema.define(:version => 1) do

end
