London Ruby User Group:A Modular Approach to Views

A Modular Approach to Views
Jon Gilbraith is not keen on HTML as he finds it takes the joy out of programming and it also seems unsightly. Alternatives like Haml are a nice improvement, but with Haml things still get untidy once the logic is laid out. The standard Rails solution is Helpers Partials, which are a good way to break up the view for big partials. But for small snippets of html one has to use all sorts of weird naming and path combinations to try to sort and identify them. They often have as much or more Ruby in them than html anyway.

For these situations a helper might be a better solution. Helpers are generally used for small jobs e.g. generating a few tags. Generating html within a helper is generally quite messy. One option is to define logical chunks of a view with blocks of idiomatic Ruby. The result can be clean, clear, descriptive and dry; forcing strong modularisation which leaves cleaner and better structured markup and style, a good foundation for separating the design and development tasks, straight forward refactoring and reuse and a good foundation for fragment caching.

ABOUT JON GILBRAITH

Jon Gilbraith has been working on taking a modular approach to views and creating builder classes to abstract structural html and view logic into Ruby blocks.
