page title

=begin rdoc Definitions: * master template: used to render a node. It is used depending on it's 'target_klass' filter. * helper template: included into another template. Render ---> Master template --include--> helper template --include--> ... For master templates, the title is build from the different filters (target_klass, mode, format): Klass-mode-format. Examples: Node-index, Node--xml, Project-info. Note how the format is omitted when it is 'html'. Other templates have a title built from the given name, just like any other node. =end class Template < TextDocument MODE_FORMAT_FROM_TITLE = /^([A-Z][a-zA-Z]+?)(-(([a-zA-Z_\+]*)(-([a-zA-Z_]+)|))|)(\.|\Z)/ property do |p| p.string 'target_klass' p.string 'format' p.string 'mode' p.string 'tkpath' p.index(IdxTemplate) do |record| { 'format' => record.format, 'mode' => record.mode, 'tkpath' => record.tkpath, 'skin_id' => record[:section_id], } end safe_property :tkpath, :mode, :target_klass, :format end attr_protected :tkpath before_validation :rebuild_tkpath validate :validate_section, :validate_target_klass # Class Methods class << self def accept_content_type?(content_type) content_type =~ /text\/(html|zafu)/ end end # Class Methods def filename "#{title}.#{ext}" end def skin @skin ||= secure(Skin) { Skin.find(skin_id) } end def rebuild_tkpath(rebuild_tklass = nil) if target_klass # this is a master template (found when choosing the template for rendering) if klass = rebuild_tklass # rebuilding index self.target_klass = klass.name self.tkpath = klass.kpath self.title = title_from_mode_and_format elsif klass = VirtualClass[target_klass] self.tkpath = klass.kpath end else self.tkpath = nil end end private def set_defaults self.mode = nil if mode.blank? self.target_klass = nil if target_klass.blank? super # Force template extension to zafu self.ext = 'zafu' # Force template content-type to 'text/zafu' self.content_type = 'text/zafu' if prop.title_changed? if title =~ MODE_FORMAT_FROM_TITLE # title changed force update self.target_klass = $1 unless prop.target_klass_changed? self.mode = ($4 || '') unless prop.mode_changed? self.format = ($6 || 'html') unless prop.format_changed? else # title set but it is not a master template name self.target_klass = nil self.mode = nil self.format = nil end end if version.edited? self.mode = mode.gsub(/[^a-zA-Z\+]/, '') if mode if !target_klass.blank? # update title self.format = 'html' if format.blank? self.title = title_from_mode_and_format if text.blank? && format == 'html' && mode != '+edit' # set a default text if target_klass == 'Node' self.text = < page title END_TXT else self.text = "\n" end end end end end def title_from_mode_and_format(opts={}) opts[:format] ||= format opts[:mode ] ||= mode opts[:target_klass ] ||= target_klass format = opts[:format] == 'html' ?
