Rails - May 2008 - validates_numericality_of with greater_than* less_than* simply don't work

It seems that the validations for:

greater_than
greater_than_or_equal_to
less_than
less_than_or_equal_to
equal_to
odd
even

Simply do not work (Rails 2.0.2). I''ve tried every combination I can
think of and these never seem to fire.

How exactly did you use it?

Here''s a sample

validates_numericality_of :attribute, :greater_than => 300

I''ve tried it multiple ways, including the very simplest like
you''ve
shown. Nothing seems to work.

Here are two exact lines:

validates_numericality_of :monthly_service_charge, :greater_than_or_equal_to
=> 0, :message => "must be greater than zero"

validates_numericality_of :count_sheets_per_week, :greater_than =>
0, :only_integer => true, :allow_nil => true, :message => "must be
greater than zero"

What''s the message you get? Have you tried in console? Did you have
rails 2.0 installed? What''s your version of ActiveRecord then?

I try to do model.valid? and I get true even though the values have
been set to something invalid (like a negative number).

Rails 2.0.2

How do I find the ActiveRecord version?

activerecord (2.0.2, 1.15.3)
rails (2.0.2, 1.2.3)

Is this the problem? I have an outdated ActiveRecord?

It looks like I have a few outdated things, but ActiveRecord is not
among them:

mongrel (1.0.1 < 1.1.4)
actionwebservice (1.2.3 < 1.2.6)
rake (0.7.2 < 0.8.1)
net-sftp (1.1.0 < 2.0.0)
gem_plugin (0.2.2 < 0.2.3)
cgi_multipart_eof_fix (2.1 < 2.5.0)
net-ssh (1.0.10 < 2.0.1)
daemons (1.0.5 < 1.0.10)
capistrano (1.4.1 < 2.3.0)
fastthread (1.0 < 1.0.1)

Unless there is something hidden in one of these.

I might be onto something When I do a complete update of everything,
actionwebservice triggers an update of activerecord from 1.15.3 to
1.15.6.

We''ll see what happens after this.

Bingo. That fixed it. Thanks for your help! I''ll know to keep my gems
up to date now.

I was wrong. After all of the updates it still isn''t working. :-(

This is vexing and frustrating.

I cannot even seem to get the debugger going to try and walk into
things and see what''s happening.

I just tried validates_numericality_of with greater_than and it worked  
fine. What are you doing (I saw some model definitions in a previous  
post of yours), what is the interaction with the model where it''s  
misbehaving?

It seems that there was something in my project that was keeping it
using an older version of rails.

RAILS_GEM_VERSION = ''1.2.3'' unless defined? RAILS_GEM_VERSION

I''ve commented that out. The project is now update to date. All gems
are up to date. These validations now are working. But now rake
test:units is failing with a "uninitialized constant CreateFeedbacks".
This must be a different problem so I''ll keep digging.

That''s simply because you created the app with rails 1.2.3. You need
to upgrade to rails 2.0.2. What you have in gem and what you have in
apps may be different.
