merb_resourceful

merb_resourceful is a plugin similar to resource_controller or make_resourceful for rails.

Usage

Generate a new resource (this will change in the future)

merb-gen resource my_resource

Edit app/controllers/my_resources.rb and leave the class declaration only

class MyResources < Merb::Controller resourceful end

This gives you a basic controller with a few defaults (destroy isn’t implemented yet).

Nested resources

class MyResources < Merb::Controller resourceful :belongs_to => :my_parent

The children will be accessed through parent.[children association]
E.g. my_parent.my_resources
this will be configurable in the future
def my_parent
@foo ||= session.user.parents.get(params[:foo_id])
end
end

Scoped resources

class MyResources < Merb::Controller resourceful :scope => :scope_method

works just like :parent, but doesn’t use @bar for routing
def scope_method
@bar ||= session.user.parents.get(params[:bar_id])
end
end

Per-action settings

class MyResources < Merb::Controller resourceful do index :layout => ‘my_special_layout’ create :scope => :scope_for_create end def scope_for_create @baz = get_me! end end

Param injection

Merb already supports this with the defer_to method in the router, but I think this is way more explicit.

class MyResources < Merb::Controller resourceful do index :params => lambda {{ :creator => session.user }} # passes :creator as a param to MyResource.new create :params => lambda {{ :creator => session.user }} # passes :creator as a param to the resource’s update method end end

Lots more to come
