/!\ My version numbers mean that they are stable when they are pair (2,4,6,8…) and nearly bugfree when they finish with a 0 (10,20,30) so if you see version 1, just know that it's not meant for production now!


A slice for the Merb framework that provides the core static pages functionnalities. Just see the views for edit.

To see all available tasks for StaticSlice run: rake -T slices:static_slice

CUD Customization

If you want to protect the CUD actions, you must know that: ALL of them are located in a content named for_cud. simple. If you want to change the look of the CUD operations, it's stored in a partial named _cud. But please see the default one first.


A partial called _sidebar may help you with Sidebar customization.


  • dependency (config/init.rb)

    # add the slice as a regular dependency dependency 'static_slice'

  • router

    # example: /static_slice/:controller/:action/:id add_slice(:StaticSlice) # example: /foo/:controller/:action/:id add_slice(:StaticSlice, 'foo') # same as :path => 'foo' # example: /:lang/:controller/:action/:id add_slice(:StaticSlice, :path => ':lang') # example: /:controller/:action/:id slice(:StaticSlice)

  • rake

    rake slices:static_slice:install


You can put your overrides here: host-app/slices/static_slice/app - controllers, models, views ...

Templates are located in this order:

  1. host-app/slices/static_slice/app/views/*
  2. gems/static_slice/app/views/*
  3. host-app/app/views/*

You can use the host application's layout by configuring the static_slice slice in a before_app_loads block:

Merb::Slices.config[:static_slice] = { :layout => :application }

By default :static_slice is used. If you need to override stylesheets or javascripts, just specify your own files in your layout instead/in addition to the ones supplied (if any) in host-app/public/slices/static_slice.

In any case don't edit those files directly as they may be clobbered any time rake static_slice:install is run.

About Slices

Merb-Slices is a Merb plugin for using and creating application 'slices' which help you modularize your application. Usually these are reuseable extractions from your main app. In effect, a Slice is just like a regular Merb MVC application, both in functionality as well as in structure.

When you generate a Slice stub structure, a module is setup to serve as a namespace for your controller, models, helpers etc. This ensures maximum encapsulation. You could say a Slice is a mixture between a Merb plugin (a Gem) and a Merb application, reaping the benefits of both.

A host application can 'mount' a Slice inside the router, which means you have full over control how it integrates. By default a Slice's routes are prefixed by its name (a router :namespace), but you can easily provide your own prefix or leave it out, mounting it at the root of your url-schema. You can even mount a Slice multiple times and give extra parameters to customize an instance's behaviour.

A Slice's Application controller uses controller_for_slice to setup slice specific behaviour, which mainly affects cascaded view handling. Additionaly, this method is available to any kind of controller, so it can be used for Merb Mailer too for example.

There are many ways which let you customize a Slice's functionality and appearance without ever touching the Gem-level code itself. It's not only easy to add template/layout overrides, you can also add/modify controllers, models and other runtime code from within the host application.

To create your own Slice run this (somewhere outside of your merb app):

merb-gen slice <your-lowercase-slice-name>
