Rake provide an easy to use task execution mechanism, but it also has some useful logic for extending existing tasks. Here are a few examples of the kinds of Rake tasks I've been using to make my life easier.
It's possible for one task to call another, but it's also possible for this to go between namespaces:
$ rake db:environment will invoke both the
We use this to integrate with other task libraries, e.g. ActiveRecord.
Sometimes it's useful to have stateful tasks:
$ rake verbose deploy will print out more detailed information.
We use this when running tasks as background jobs - verbose is not defined unless we want extra output for debugging.
You can use this to make flexible filters and tasks which can be configured to do different things:
We use tasks like these to export data for customers - we almost always have some specific requirements - but we can usually chain together a set of existing tasks to get the desired output.
It's possible to define multiple tasks with the same name. This is useful if you want to combine multiple files containing tasks
$ rake deploy will invoke both tasks.
We use this to keep our
.rake files simple, focused and organised.
