Instantrails users - Dec 2005 - Upgrading Instant Rails to Rails 1.0 RC5 (aka 0.14.4)

Rails to Rails 1.0 RC5 (aka 0.14.4) was released yesterday. You can upgrade
your Instant Rails installation to this new version by usi the main menu to
open a Ruby Console Window and then running the command:

      gem install rails --include-dependencies

Anyone having any trouble with the update? I have a model that uses
the find method and it refuses to return any data now. It doesn''t
error out, I just don''t get what I expect to get. Worked fine on Linux
with Rails 0.14.3 but does not work on Instant Rails with 0.14.4

Ok, after updating I was having some weird problems with Instant
Rails. Now I''m now getting the following error:

Lost connection to MySQL server during query

After googling seems every answer to this problem is the fact that the
MySQL Ruby bindings are not installed. Is there a Win32 port of them
somewhere?

The pure Ruby bindings are included with Rails, but the C based bindings are
not. Obviously the Ruby bindings are there or you would not have gotten a
connection to lose.

Are you saying that the answers you found indicated that installing the C
based bindings would solve this problem?

That''s what google says. I reinstalled Instant Rails, updated and
don''t seem to be getting that error anymore. What I get now is a
NoMethodError when I try to call the find function from within my
model. I have a simple test app with just one call to ''find''
in my
model for a simple table that stores a username and a hashed password.
This all works fine on Linux / Rails 0.14.3 but refuses to work on
Instant Rails either 0.14.3 or 0.14.4. I''m using only Webrick to test.
I''m not using Apache / SCGI because they are overkill for me.

I went to my linux box, upgraded to 0.14.4 and everything was still
working fine. I can''t get the same code to work with Instant Rails, my
guess is because of the fact that there is no Ruby-MySQL C binding.
That is the only difference between both setups. I use only Rails +
MySQL and Webrick. Such is life I suppose.

Theoretically the same code should still work, right? I am a n00b with
Rails and have only developed a very basic login system that works on
a Linux machine with Rails 0.14.4 and MySQL 4.1.12. It only has one
table and one model with a method that calls find. When I try to run
the same code on Instant Rails using Webrick (that is my preferred
development server) it fails to run giving me a NoMethodError. When I
run on Linux it works as expected. If I comment out the find method in
my model then I don''t get the error on Instant Rails but yet the code
cannot function properly without it.

I can''t speak for anyone else, but I really can''t say without
seeing the code...

Anyway this is the code that causes the problem on Instant Rails.

require ''digest/sha1''

class User < ActiveRecord::Base
	
	def self.validate(name,pass)
		find(:first, :conditions => [ "username = ? AND password = ?",
name,
Digest::SHA1.hexdigest(pass) ])
	end

end

I''ll get a NoMethodError on the find method. If I comment it out, the
app will run but of course it doesn''t validate a user.

Ok, first problem, you probably don''t mean to use validate(), since
that is a
method called when a record is saved; see
http://api.rubyonrails.com/classes/ActiveRecord/Validations.html

I don''t know if that is causing the error or not.

Could you also post the exact stack trace you are getting?

ok, but the weird thing is that it works on linux. I have since been
rewriting the code to make it better. I''ve got rid of that method now.

I read through the comments, and it appears that there are some MySQL bugs
in this Rails release. Here is what DHH said:

*David Heinemeier Hansson* said 1 day later:

To anyone who''ve had database trouble with MySQL, please upgrade to the
beta
gems with: gem install rails?source
http://gems.rubyonrails.org?include-dependencies. We''ve fixed some
important
snags.
