def slice; self.class.slice; end

Parameters:

  • *args (Array[Symbol,Hash]) —

    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

Returns:

  • (String) —

    A uri based on the requested slice.
