Class Method Details

.included(base) ⇒ Object

Even more convenient access to commands. Include Commands in the generator Base class to get a nice #command instance method which returns a delegate for the requested command.

# File 'lib/rails_generator/commands.rb', line 20

def self.included(base)
  base.send(:define_method, :command) do |command|
    Commands.instance(command, self)
  end
end

.instance(command, generator) ⇒ Object

Here’s a convenient way to get a handle on generator commands. Command.instance(‘destroy’, my_generator) instantiates a Destroy delegate of my_generator ready to do your dirty work.

# File 'lib/rails_generator/commands.rb', line 13

def self.instance(command, generator)
  const_get(command.to_s.camelize).new(generator)
