Tyler, I wasn't able to reproduce the error message above using this
simplified example:
module ApplicationHelper
def self.make_user_select_collects(assoc_id_param)
module_eval %{
def select_collect_by_#{assoc_id_param}(klass, assoc_id,
order_by_col='full_name')
klass.find_all_by_#{assoc_id_param}(assoc_id,
:order => order_by_col.to_sym).collect {|s| [s.full_name, s.id]}
end
}
end
def self.model_names
models = Array.new
Dir["app/models/**/*.rb"].each do |f|
models <<
File.basename(f).sub(/.rb$/,'').titlecase.gsub(/\s/,'').constantize
end
models
end
ids = Array.new
model_names.each do |klass| #model_names
klass.column_names.grep(/_id$/).each do |assoc_id|
unless ids.member?(assoc_id)
ids << assoc_id
# make_user_select_collects(assoc_id)
end
end
end
puts "Model #{self} completed"
end
darnoc-desktop:app conradwt$ ruby helpers/application_helper.rb
=> Model ApplicationHelper completed
BTW, I used Ruby 1.9.1 to execute the above code. I'll try the above on my
laptop using
Ruby 1.8.6 to see if it's consistent with Ruby 1.9.1.
