Hi,
Am getting the error "undefined method `each' for #<Mysql:0x483f2d0>"
when I try to run a "rake db:migrate" on a very simple example for a
Mysql database. This follows a very basic setup procedure that works
with sqlite3, but fails when I try to use Mysql (note that I have
verified that the db on mysql is created and accessible to rails)
>rails photos
>cd photos
>ruby script/generate scaffold photo filename:string thumbnail:string
>description:string
>rake db:migrate
at this point I get an error (see below). Note that the
schema_migrations table is created and if I run the rake command then
the table photos is also created (but I get a command out of sequence
error from rails).
I have read relevant posts regarding versions of mysql and
libmysql.dll which I have taken action on.
I would appreciate any clues as it is driving me nuts %).
I am using:
MS Windows XP Home Ediition Version 2002 SP3
ruby ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]
rails 2.2.2
mysql gem 2.7.3
Mysql 5.1.31-community
Cheers
Barry
