Rails - Jul 2006 - validate method doesn''t recognize another instance method

All,

I am attempting to do some custom validation on my object.

Here is my validate method:
protected
  def validate
    puts "Do I have the target_list_ids method? " + 
self.methods.include?(''target_list_ids'').to_s

if target_list_ids.nil? || target_list_ids.length == 0
      errors.add_to_base("You must choose at least one target list for 
this job")
    end

    puts "Do I have the Fax method? " + 
self.methods.include?(''Fax'').to_s
    if Fax.nil?
      errors.add_to_base("You must choose at least one report 
destination (either email or fax) for this job")
    end
#    puts "checking"
#    puts Fax.nil?
#    puts EMAIL.nil?
#    puts "EMAIL: #{EMAIL}"
#    if ((Fax.nil?) || (Fax == '''')) && ((EMAIL.nil?)
|| (EMAIL == ''''))
#
#    end
  end

All,

I am attempting to do some custom validation on my object.

Here is my validate method:

  def validate
    puts "Do I have the target_list_ids method? " + 
self.methods.include?(''target_list_ids'').to_s

    if target_list_ids.nil? || target_list_ids.length == 0
      errors.add_to_base("blah")
    end

    puts "Do I have the Fax method? " + 
self.methods.include?(''Fax'').to_s
    if Fax.nil?
      errors.add_to_base("blah")
    end
  end

and here is the output:

Do I have the target_list_ids method? true
Do I have the Fax method? true
uninitialized constant Fax

So as you can see, I am calling the target_list_ids method without 
incident but can''t seem to call the Fax method, which I just showed as 
existing.

Can anyone explain to me why my "Fax" method can''t be called
in the same
way that my "target_list_ids" method can?

I''ll be reading the validate method.

I love this API where I get to read every bit of source code - it really 
enhances my productivity ;).

Thanks,
Wes

I notice that if I put parens after Fax, so if Fax().nil?, it seems to 
work.

However, why do I have to put parens after one method name but not the 
other?

Oh my God, it''s because Fax is capitalized, isn''t it?  Oh
boy...

Thanks,
Wes
