Basics

Controllers

MainController maps to '/'

BlueController maps to '/blue'

...unless you use map

Action methods accept arguments via URL

http://localhost:7000/archive? page=2 request[:page] == '2'

Errors redirect to error action

Routing (String Routers) Ramaze::Route [ '/foo' ] = '/bar' # '/foo' => '/bar'

Routing (Regex Routers) Ramaze::Route [ %r!^/(d+).txt$! ] = "/text/%d" # '/123.txt' => '/text/123'

Routing Ramaze::Route [ 'name of route' ] = lambda { |path, request| '/bar' if path == '/foo' and request[ :bar ] == '1' } (Lambda Routers) # '/foo' => '/foo' # '/foo?bar=1' => '/bar'

Testing

Ezamar Erubis (bundled) (default) (my favorite) (plenty of other choices)

inline vs. external

START NO YES Run return value of action through templating engine Send to browser External Template Is there an external template?

Instance variables set in the action can be accessed in template (just like in Rails)

(convention) /view

(configuration) view_root 'my_templates'

Layouts

# apply to all actions except index layout :layout deny_layout :index # apply only to index layout :layout => [ :index ] Layouts

Ezamar Very simple reimplementation of the Templating-engine found in Nitro. <?r rubycode ?> == <% rubycode %> #{ rubycode } == <%= rubycode %>

Ezamar::Element

Models

That's up to you to figure out...

ActiveRecord DataMapper Sequel Og DBI

Ramaze::Store
