Astaire: The basic Sinatra DSL for your Rails 3 apps
Astaire allows the use of the basic Sinatra get / post / put / delete DSL inside of Rails controllers. This allows defining quick actions without having to update config/routes.rb. For example:
class ContactController < ActionController::Base
get "/contact" do
render :contact_form
end
post "/contact" do
# handle form input
redirect_to homepage_path
end
end
Installation
Add the following to your application's Gemfile
gem "astaire"
Then, run bundle install and you are good to go.
Usage
Currently, Astaire provides 4 class level methods available in the
controller: #get, #post, #put, and #delete. With these methods
you can define actions and routes all at once.
class MyController < ActionController::Base
# Get the contact form
get "/contact" do
render :contact_form
end
# The paths can also have named parameters and
# optional segments
#
# /say/hello => "I say: hello"
# /say/hello/world => "I say: hello world"
#
get "/say/:one(/:two)" do
words = [params[:one], params[:two]].compact.join(' ')
render :text => "I say: #{words}"
end
end
It is possible to name actions such that regular URL helpers can generate them.
class MyController < ActionController::Base
# Will output /hello
def index
render :text => hello_path
end
get "/hello", :as => :hello do
render :text => "hello"
end
end
Astaire supports inline templates in the same style as Sinatra. For example:
class MyController < ActionController::Base
get "/hello" do
render :greetings
end
end
__END__
@@ greetings.html.erb
Greetings to you.
TODO
I guess, at this point I'm just putting what I have into the wild. Next steps will be determined by feedback that I get.
