Overview

Public: Instances of TopMenuItem should be instantiated from segments contained in SiteSetting.top_menu. Exposes relevant properties and methods that dictate which query methods should be called from the ListController. Segment data should start with a route fragment in one of the following formats:

a topic route, such as 'latest' or 'new' (see ListController for valid options)
the literal string "categories"
a specific category route, must start with 'category/' followed by the route, i.e. 'category/xyz'

A topic route can optionally specify a single category to exclude using the ‘-category’ option, i.e. ‘new,-xyz’

Examples

item = TopMenuItem.new('unread')
item.name           # => "unread"

item = TopMenuItem.new('latest,-video')
item.name           # => "latest"
item.has_filter?    # => true
item.filter         # => "video"

item = TopMenuItem.new('category/hardware')
item.name                     # => "category"
item.has_filter?              # => false
item.has_specific_category?   # => true
item.specific_category        # => "hardware"
