ACTIVE_CLASS = 'is-active'.freeze
def active_for(options)
name_of_controller = options.fetch(:controller) { nil }
name_of_action = options.fetch(:action) { nil }
request_path = options.fetch(:path) { nil }
return ACTIVE_CLASS if request_path && request_path == request.path
if name_of_controller == controller_name
ACTIVE_CLASS if name_of_action.nil? || (name_of_action == action_name)
<div id="navbar" class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-right">
<li class='<%= active_for(path: "/users/#{}") %>'>
<%= link_to current_user %>
<li class='<%= active_for(controller: "events") %>'>
<%= link_to events_path %>
