random code and what not

Calling rake tasks from another rake task

This turns out to be pretty straight forward, but was not obvious

Rake::Task['task_name'].execute

A rake task to rebuild the development database
desc 'drop, create and rebuild development db'
task(:rebuild_development_db) do
  puts "drop the db"
  Rake::Task['db:drop'].execute 
  puts "create the db"
  Rake::Task['db:create'].execute
  puts "run the migrations"
  Rake::Task['db:migrate'].execute
  # do other stuff...
end

Also if the task you are calling takes args you can pass them in a hash to the execute method

some_value = "testing"
Rake::Task["your_task"].execute({:some_param => some_value})
