Hi guys,
I am a completely ruby & rails newbie. i have being struggling on this
issue for almost 2 days, still can not figure out the problem.
there are two websites i’m trying to set up a development environment on
my pc running windows xp 32 bit version. a front-end customer facing
page & back-end admin page.
the procedure i have gone through is:
- install ruby version 1.8.6
- update rubygems version to the latest
- install rails version 2.3.5
- install mysql adapter
- install mongrel & mongrel_service
- install all required gems for the application
- create a fresh new rails app & replace the required folders & files
from the source - create & migrate the mysql database and then resoted it with the data
from live site - start the server and it’s running without any problems for the
front-end site
then i went through the same process (from 7 to 9) for the back-end
admin site as well, and type “rake gems:install” to install any required
gems. then start the server, error shows as the following in the log
file:
** has_many_polymorphs: autoload hook invoked
