Method not available within same module as definition


#1

This will probably be embarrassingly obvious. It acts as if it’s an

evaluation order issue (like the method call is happening prior to the

method definition). But that isn’t the case. The model_names method

works fine on the console. I’m missing a core concept obviously.

Error message from test

tylers-mbpro:test tyler$ ruby helpers/application_helper_test.rb
/Users/tyler/versioned/tma-code/rails/facilit-e/app/helpers/application_helper.rb:23:

def self.make_user_select_collects(assoc_id_param)

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

end

Thanks for any help

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.

Conrad,

Interesting…please do let me know your results with 1.8.6.

Tyler, I’m seeing the same result using Ruby 1.8.6. BTW, here’s the
exact
version that I’m running in regards to 1.8.6:

ruby 1.8.6 (2008-08-11 patchlevel 287) [i686-darwin9.6.0]
