Given something like:
namespace :my_tasks do task :foo do do_something end task :bar do do_something_else end task :all => [:foo, :bar] end How do I make :all be the default task, so that running rake my_tasks will call it (instead of having to call rake my_tasks:all)?

To run a specific task (for example, about ), use the the task name as a parameter (this is equivalent to running the command rake about ). More examples of Rake commands: To run a default task, run the rake utility without any parameters: rake .
Rake is a popular task runner for Ruby and Rails applications. For example, Rails provides the predefined Rake tasks for creating databases, running migrations, and performing tests. You can also create custom tasks to automate specific actions - run code analysis tools, backup databases, and so on.
You can create these custom rake tasks with the bin/rails generate task command. If your need to interact with your application models, perform database queries and so on, your task should depend on the environment task, which will load your application code.
Including => :environment will tell Rake to load full the application environment, giving the relevant task access to things like classes, helpers, etc. Without the :environment , you won't have access to any of those extras.
Place it outside the namespace like this:
namespace :my_tasks do task :foo do do_something end task :bar do do_something_else end end task :all => ["my_tasks:foo", "my_tasks:bar"] Also... if your tasks require arguments then:
namespace :my_tasks do task :foo, :arg1, :arg2 do |t, args| do_something end task :bar, :arg1, :arg2 do |t, args| do_something_else end end task :my_tasks, :arg1, :arg2 do |t, args| Rake::Task["my_tasks:foo"].invoke( args.arg1, args.arg2 ) Rake::Task["my_tasks:bar"].invoke( args.arg1, args.arg2 ) end Notice how in the 2nd example you can call the task the same name as the namespace, ie 'my_tasks'

Not very intuitive, but you can have a namespace and a task that have the same name, and that effectively gives you what you want. For instance
namespace :my_task do task :foo do do_foo end task :bar do do_bar end end task :my_task do Rake::Task['my_task:foo'].invoke Rake::Task['my_task:bar'].invoke end Now you can run commands like,
rake my_task:foo and
rake my_task If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
