Hello World Listing 1: hello.rb Simple. One file(4kb) vs Rails (900kb).
Run ramaze start ruby hello.rb thin start Pow, Passenger, Mongrel etc Rack based
POLS Principle of Least Surprise Law of Least Astonishment It should work because I made it work No “magic”
Freedom No set structure for organizing your files Flexible BUT: Could lead to messed up code Use what makes most sense to you (and your team) Sensible defaults Prototypes ramaze create project
Views Listing 2: view/index.rhtml (using Erubis) By default Ramaze looks for the template in the path called ‘view’, but can be overriden via setting Ramaze.options.views = ‘view_path’ Add @message in controller You could also add inline views in your really wanted to.
Models Use any ORM Sequel Active Record Standalone classes
Models (cont.) Simple Model: in hello.rb *Modify controller to use this
Organizing your code Use prototype Allows opportunity to refactor and build our code as we go along Ex: Remove model and controller from hello.rb into separate files Ramaze.acquire – broken in 1.9.2 as of 5/2011
Routing controllers/another_controller.rb Looks for views in ‘view/bye/’ view_path/route_name
Routing (cont.) You can also specify routes via configuration regex routes
Other Stuff Layouts Placed in view path Just call layout ‘layout_name’ in controller to set Helpers paginate user flash https://github.com/Ramaze/ramaze/tree/master/lib/ramaze/helper Middlewares
Great things about Ramaze Low memory usage Cheaper than Rails Uses 60% less memory vsPadrino Freedom Simple codebase Focus on Ruby, rather than the framework
Cons Outdated documentation Slightly slower compared to Padrino Can’t use Rails specific gems You can but with slightly more work
Still Great Things Good community Freenode #ramaze Google groups Know exactly what your code does Know where to place/find your code (because you organized it)
Conclusion Great to use for smallish projects When server memory is an issue Great way to help transition developers from other technologies who are used to their “own way of doing things” Let’s you focus on Ruby Good alternative to Rails, use it when you are sick of Rails In the end, Ramaze, Rails, Sinatra are tools: It’s what’s in your heart that counts, use frameworks that make you happy.
