    <p>I am stuck on the part in chapter 6. It is a dungeon text-adventure game with rooms and a player that moves around. I keep getting a noMethod error for the .detect method used in the find_room_in_dungeon method. I assume that I am probably missing something but I just can't figure out what. I would really appreciate if someone could help me out. thanks.</p> <pre><code>class Dungeon attr_accessor :player def initialize(player_name) @player=Player.new(player_name) @room = [] end def add_room(reference, name, description, connections) @room &lt;&lt; Room.new(reference, name, description, connections) end def start(location) @player.location=location show_current_description end def show_current_description puts find_room_in_dungeon(@player.location).full_description end ### def find_room_in_dungeon(reference) @rooms.detect { |room| room.reference == reference } end ### def find_room_in_direction(direction) find_room_in_dungeon(@player.location).connections[direction] end def go(direction) puts "you go " + direction.to_s @player.location= find_room_in_direction(direction) show_current_description end class Player attr_accessor :name, :location def initialize(name) @name = name end end class Room attr_accessor :reference, :name, :description, :connections def initialize(reference, name, description, connections) @reference =reference @name =name @description=description @connections=connections end def full_description @name + "/n/n you are in" + @description end end end my_dungeon= Dungeon.new("adventurer") my_dungeon.add_room(:largecave, "large cave", "a very large cave", {:west =&gt; :smallcave}) my_dungeon.add_room(:smallcave, "smallcave", "a small cave", {:east =&gt; :largecave}) my_dungeon.start(:largecave) </code></pre>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
