Getting error on a group select

Rails
1

Hi,

I’m very new with Ruby and Rails. I have read Agile Web D.
with Rails and was trying to create a grouped selection list by
following his example on page 359.

My helper looks like this:

module LoginHelper
AssocOption = Struct.new(:code_name, :display_name)

class AssocType
attr_reader :type_name, :options

def initialize(name)
  @type_name = name
  @options = []
end

def <<(option)
  @options << option
end

end

none = AssocType.new(“NONE”)
none << AssocOption.new(“None”, “None”)
none << AssocOption.new(“All”, “All”)

dr = AssocType.new(“DOCTORS”)
dr << AssocOption.new(“Dr. Dave”, “Dave Pancost”)
dr << AssocOption.new(“Dr. Dan”, “Daniel Foreman”)
dr << AssocOption.new(“Dr. Mike”, “Michael Carney”)

co = AssocType.new(“COMPANIES”)
co << Assoc.Option.new(“Sidekick Design”, “Sidekick Design”)
co << Assoc.Option.new(“Strategic Web Concepts”, “Strategic Web
Concepts”)

ASSOCIATION_OPTIONS = [ none, dr, co ]
end

My View looks like this:

<select name="user[associationl]" id="user_association">
<%=
option_groups_from_collection_for_select(ASSOCIATION_OPTIONS,
											 :options, :type_name,
											 :code_name, :display_name,
											 @user.level)
%>
</select>

The error message I’m getting is this:

uninitialized constant ASSOCIATION_OPTIONS
Extracted source (around line #23):

20: -->
21:
22: <%=
23: option_groups_from_collection_for_select(ASSOCIATION_OPTIONS,
24: :options, :type_name,
25: :code_name, :display_name,
26: @user.level)

My question: Didn’t I initialize ASSOCIATION_OPTIONS in the helper?
What did I do wrong and how to I get the group select to work? I tried
to follow exactly what I read in the book, but it doesn’t seem to work,
so I’m assuming I did something wrong, I just can’t quite see what it
is.

Any suggestions?

Thanks,

Dave
