I’m having a problem importing a class from another project (not a RoR
application). What’s the right way to require such a file?
I have a class ModelPathwayObject. It’s in
#{RAILS_ROOT}/…/lib/model_pathway_object.rb , so I add that path to
config.load_paths. In config/environment.rb:
Rails::Initializer.run do |config|
config.load_paths += %W( #{RAILS_ROOT}/…/lib )
end
I then tried to require the file from config/environment.rb by appending
require ‘model_pathway_object’
With these changes WEBrick wouldn’t start:
[luca@zirellu pa_web] ./script/server
=> Booting WEBrick…
[luca@zirellu pa_web]
So I moved the require to the top of my controller’s file. Now WEBrick
starts, but the first time I place a request to the controller I get an
error
(Gem::LoadError in #, trace at the
bottom
of this message), but afterwards it works fine.
I figure I’m doing something wrong, otherwise the thing would work from
the
first request. Can someone tell me what the right way to do this is?
Thanks
in advance.
