Combining many rake tasks into one rake task
You can do it with dependencies on a task with no body.
desc 'This rebuilds development db'task :rebuild_dev => ["db:drop", "db:create", "db:migrate", "db:load"]
You want invoke
not execute
. A little excerpt from my own code showing how to pass variables:
namespace :clients do task :create, [:client] => ["clients:creation:checks"] do |t, args| Rake::Task["clients:creation:git"].invoke(client, password) Rake::Task["server:virtualhost:create"].invoke(client) Rake::Task["server:virtualhost:enable"].invoke(client) Rake::Task["server:reload"].invoke Rake::Task["db:roles:create"].invoke(client, password) Rake::Task["db:create"].invoke(client, client) Rake::Task["db:migrate"].invoke(client) endend
Alternatively, you can make the task depend upon another task as I have done above with :create
depending upon clients:creation:checks
.
Just to clarify, a namespace is for grouping tasks, so you must actually define the tasks within the namespace as I have above. You can't simply call tasks from within a namespace.
So your code above should be:
desc 'This rebuilds development db'task :rebuild_dev do Rake::Task["db:drop"].invoke Rake::Task["db:create"].invoke Rake::Task["db:migrate"].invoke Rake::Task["db:load"].invokeend
namespace :rebuild_dev do desc 'This rebuilds development db' task :clean_slate => :environment do Rake::Task["db:drop"].invoke Rake::Task["db:create"].invoke Rake::Task["db:migrate"].invoke Rake::Task["db:load"].invoke endend
