slice() click to toggle source

Reference this controller’s slice module directly.

@return <Module> A slice module.

# File lib/merb-slices/controller_mixin.rb, line 122
def slice; self.class.slice; end
slice_url(*args) click to toggle source

Generate a url - takes the slice’s :path_prefix into account.

@param *args>

There are several possibilities regarding arguments:
- when passing a Hash only, the :default route of the current 
  slice will be used
- when a single Symbol is passed, it's used as the route name,
  while the slice itself will be the current one
- when two Symbols are passed, the first will be the slice name,
  the second will be the route name
- a Hash with additional params can optionally be passed

@return <String> A uri based on the requested slice.

@example slice_url(:controller => ‘foo’, :action => ‘bar’) @example slice_url(:awesome, :format => ‘html’) @example slice_url(:forum, :posts, :format => ‘xml’)

# File lib/merb-slices/controller_mixin.rb, line 141
def slice_url(*args)
  opts = args.last.is_a?(Hash) ? args.pop : {}
  slice_name, route_name = if args[0].is_a?(Symbol) && args[1].is_a?(Symbol)
    [args.shift, args.shift] # other slice identifier, route name
  elsif args[0].is_a?(Symbol)
    [slice.identifier_sym, args.shift] # self, route name
  else
    [slice.identifier_sym, :default] # self, default route
  end
  
  routes = Merb::Slices.named_routes[slice_name]
  unless routes && route = routes[route_name]
    raise Merb::Router::GenerationError, "Named route not found: #{route_name}"
  end

  route.generate(args, params)
