Hello,
I have successfully installed some local gems on my rails host. I
checked that through irb:
irb(main):002:0> require ''rubygems''
=> true
irb(main):003:0> require_gem ''mylocalgem''
=> true
irb(main):003:0> a = MyLocalGem::MyClass.new
=> #<MyLocalGem::MyClass:0x409a343c [bunch of stuff from MyClass]>
I''m still unable to make my rails application use that gem.
config/environment.rb (at the end):
ENV[''GEM_PATH''] =
''/usr/lib/ruby/gems/1.8:/my/path/to/local/gems''
app/helpers/application_helper.rb:
require ''rubygems''
require_gem ''mylocalgem''
module ApplicationHelper
end
app/controllers/user_controller.rb:
[...]
def show_myclass
@myclass = MyLocalGem::MyClass.new
end
[...]
And when I browse to /user/show_myclass, I get:
NameError in UserController#show_myclass
uninitialized constant UserController::MyLocalGem
#{RAILS_ROOT}/app/controllers/user_controller.rb:265:in
`show_myclass''
What did I miss?
Thanks,
Karine

Hi Karine How about installing Aptana Radrails, there is a GEM manager for you to use.

I should note the same rails app is working fine on my development server, where the gem is installed in /usr/lib... (and I only need "require ''mylocalgem''" to make it work, of course). So it''s really a configuration problem involving gems installed in a local prefix.

Is it still throwing an uninitalized constant error or is the require itself failing ? If the require isn''t failing then it''s probably nothing to do with where the gem is etc...

The problem is still there though.> have you tried doing export GEM_PATH=foo in a shell before starting > the mongrels (or whatever it is you''re using) ?I''m not starting anything, my host has its webserver configured properly to serve rails apps. GEM_PATH is in my .bash_profile, which may have helped irb to find the gem, but I''m surprised ENV[''GEM_PATH''] in environment.rb is not enough to make it work for the rails app.> Is it still throwing an uninitalized constant error or is the require > itself failing ? If the require isn''t failing then it''s probably > nothing to do with where the gem is etc...Yes, still the same unitialized constant error. Thanks for trying to nail down the issue, I guess I will have to ask my host if they have any specific config that causes this problem...

I killed the running dispatch.fcgi processes, a new one was spawned and the config files re-read. Everything is working fine now, many thanks :) Karine --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
