I get the following error message
C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:251:in
report_activate_error': Could not find RubyGem activerecord (>= 0.0.0) (Gem::LoadError) from C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:188:inactivate’

from C:/RadRails/workspace/album/my_ruby_code.rb:1
When I try execute the following piece of code
require_gem “activerecord”
class Photo < ActiveRecord::Base
end
Photo.establish_connection(
:adapter => “mysql”, :database => “album_development”)
for column in Photo.columns
print column.name, “\t”
end
puts
puts
for photo in Photo.find(:all)
for column in Photo.columns
print photo.send(column.name), “\t”
end
puts
end
I suspect it’s a class path problem or a bug in the version I am using
which is the 1.8.4 stable version
If anyone can help, i’d really appreciate it.
Thanks

Thanks for the quick response
I landed up running gem install activerecord --include dependencies
and I got it to work but there was an error at the end
Gem not found exception could not find dependencies. Do you know what
this would mean?
Also When i installed the Gem package - shouldn’t it automatically
install active record?

I am not sure about your set up. Are you saying the command “gem
install activerecord” worked fine, but you are having trouble
requiring the gem in your code? Or are you saying that you can load
the gem, but get an error when you try to use it. What is your OS?
Are you requiring ‘rubygems’ first?
Here’s what I did…
gem install activerecord
Then, in irb…
irb(main):001:0> require ‘rubygems’
=> true
irb(main):002:0> require ‘postgres’ #I require this because I’m using
postgresql
=> true
irb(main):003:0> require ‘active_record’
=> true
And then, smooth sailing from there on. Where in this process are you
getting an error?

Things seem to have gotten worse for me. I had it working at one point
now i have installed everything from scratch again nad I get the
following error - i am running windows

I installed ruby 1.8.4-20 into c:\ruby
I then installed rails using gem insall rails -r -y
I have the preference in RadRails set correctly to point to these
directories but it seems as though it’s looking for active record in a
different directory or something
Boy this sure is frustrating
thanks

Check
- your database.yml file
- that your mysql server is running
that could be it, i will check that right away, thanks

No, this is a connection error. I can reproduce this by establishing
a connection with ‘mysql’ (even though I don’t have MySQL installed).
Then, when I try to query through ActiveRecord, it gives me that
error.

- your database.yml file

I got it to work eventually, couple problems but the main thing is
that i had to change the way you include the active record gem to as
follows
gem “activerecord”
require “active_record”
An earlier version of ruby may have worked with the require_gem
“activerecord”
thanks so much for your help, one of the problems i had was that I had
not started the database so you were right.
cheers
jack (long night)
