Instance Method Details

#action(identifier, _options = {}, &block) ⇒ Object

defines a method on the model instance named after the identifier and then creates a CLI command matching that, so for example:

given a model called ‘Post’ and an action named ‘publish’ the brief CLI executable will respond to:

brief publish posts PATH_GLOB

this will find all of the Post models from the documents matching PATH_GLOB and call the publish method on them
