#Auto generate the database schema
A plugin exists to autogenerate the database schema, in order to vizualize it in a pdf file: superdumper
You can find the plugin at this address http://momo.brauchtman.net/2009/02/rails-plugin-superdumper-helps-you-visualize-your-database-schema/
This is how you would install the plugin (You will need to have a git client installed in order for this to work):
bundle exec script/plugin install git://github.com/moritzh/superdumper.git
You will also need a copy of GraphViz to generate the schema PDF
You can launch the autogeneration by typing
bundle exec rake db:superdumper
If you want to generate the dot file and the pdf file, edit
/vendor/plugins/superdumper/tasks/superdumper_tasks.rake
and comment out the following line
File.delete("#{RAILS_ROOT}/database.dot")
It will then generate both, the dot file and the pdf file.
