# 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"
