Problems after updating app from 0.6.7 => 0.6.9

I have an app that I tried to update from 0.6.7 to 0.6.9 and have run
into a
couple of problems.

It started a bit like this. I ran “rake radiant:update” which seemed to
complete successfully. But when I tried to “rake db:migrate” I was
greeted
with the error:

rake aborted!
undefined method `[]’ for #Enumerable::Enumerator:0x2329874

So I searched around and saw what looked like a cure here (11th
response):
http://groups.google.com/group/radiantcms-dev/browse_thread/thread/309b7516b2bb72f9?fwc=2

unless ‘1.9’.respond_to?(:force_encoding)
String.class_eval do
begin
remove_method :chars
rescue NameError
# OK
end
end
end

Then I ran “rake db:migrate” the migration died when it got to the
sessions
table with this error:

== 16 AddSessions: migrating

– create_table(:sessions)
rake aborted!
Mysql::Error: Table ‘sessions’ already exists: CREATE TABLE sessions
(id
int(11) DEFAULT NULL auto_increment PRIMARY KEY, session_id
varchar(255)
DEFAULT NULL, data text DEFAULT NULL, updated_at datetime DEFAULT
NULL)
ENGINE=InnoDB

(See full trace by running task with --trace)

So I truncated the sessions table and the rake task completed
successfully.
After that, “script/server” started the application with no problem. But
I
discovered a new problem, my database had been wiped clean during the
process, so when I tried viewing the site at 127.0.0.1:3000 I was
greeted
with a login screen.

I would really appreciate it if anybody who has run into similar
problems
could describe what they did to get through all this.

My setup:

Ruby 1.8.7
Rails 2.2.2, 2.1.2 (tried both)
Radiant 0.6.9

Extensions:

Archive
Blog Tags
Comments
Copy Move
Markdown Filter
Page Attachments
Share Layouts
Subscriber Lists
Textile Filter
Wine Pairing Widget (custom extension)

On OSX 10.5, but the application originated in Ubuntu and was lovingly
transferred over to the mac. Everything worked perfectly when it was
running
on radiant 0.6.7 in both OSX and Ubuntu.

Thanks,

Nate

Problem happened when you upgraded to Ruby 1.8.7. Use 1.8.6 if you can.
