BasicObject
Add a Slice in a router namespace
@param slice_module<String, Symbol, Module> A Slice module to mount. @param options<Hash, String> Optional hash, set :path if you want to override what appears on the url.
@yield A new Behavior instance is yielded in the block for nested routes - runs before the slice routes are setup. @yieldparam ns<Behavior> The namespace behavior object.
@return <Behaviour> The current router context.
@note If a slice has no routes at all, the activate hook won’t be executed.
@note Normally you should specify the slice_module using a String or Symbol
this ensures that your module can be removed from the router at runtime.

Add all known slices to the router
By combining this with Merb::Slices.activate_by_file and Merb::Slices.deactivate one can enable/disable slices at runtime, without restarting your app.
@param config<Hash>
Optional hash, mapping slice module names to their settings; set :path (or use a string) if you want to override what appears on the url.
@yield A new Behavior instance is yielded in the block for nested routes. @yieldparam ns<Behavior> The namespace behavior object.
@example all_slices(‘BlogSlice’ => ‘blog’, ‘ForumSlice’ => { :path => ‘forum’ })
@note The block is yielded for each slice individually.
# File lib/merb-slices/router_ext.rb, line 18 def all_slices(config = {}, &block) Merb::Slices.slice_names.each { |module_name| add_slice(module_name, config[module_name] || {}, &block) } end
Construct an app-level path.
# File lib/generators/templates/common/application.rb, line 17 def app_path_for(type, *segments) ::<% module_name %>.app_path_for(type, *segments) end # Construct a slice-level path def slice_path_for(type, *segments) ::<%= module_name %>.slice_path_for(type, *segments) end
# File lib/generators/templates/full/app/controllers/main.rb, line 3 def index render end
Insert a slice directly into the current router context.
This will still setup a namespace, but doesn’t set a path prefix. Only for special cases.
# File lib/merb-slices/router_ext.rb, line 67 def slice(slice_module, options = {}, &block) options[:path] ||= "" add_slice(slice_module, options.merge(:reset_controller_prefix => true), &block) end
