Rails 3.0.9: config.active_record not found - ruby-on-rails-3

I have upgraded from Rails 3.0.7 to Rails 3.0.9 and I am now getting the following error in my config/application.rb:
/Library/Ruby/Gems/1.8/gems/railties-3.1.0/lib/rails/railtie/configuration.rb:78:in `method_missing': undefined method `active_record' for #<Rails::Application::Configuration:0x10107a830> (NoMethodError)
from /Users/mathias/ruby/myapp/config/application.rb:47
On line 47 of application.rb I have
config.active_record.schema_format = :sql
It seems that
config.active_record
is not found in Rails 3.0.9 where this worked in 3.0.7. This is regardless of which method I call on config.active_record. When I comment out any usage of config.active_record, the same occurs with config.active_mailer.
And I do a require "rails/all" in the application.rb
Any help appreciated.

Got this to work with 3.1.0 through the steps outlined here. The key bit that made most of my problems disappear was to change boot.rb to
require 'rubygems'
# Set up gems listed in the Gemfile.
ENV['BUNDLE_GEMFILE'] = File.expand_path('../../Gemfile', __FILE__)
require 'bundler/setup' if File.exists?(ENV['BUNDLE_GEMFILE']

rails 3 - LoadError (cannot load such file -- zip/zip)

I'm using rubyzip to zip a csv file so uses can download it. This works perfectly in development mode. But when I tried zipping the file on the production server (rackspace) I received the error: LoadError (cannot load such file -- zip/zip). Is it a path issue? Anyone know a fix?
The error is being called in my code on this line: require 'zip/zip'
I've tried the solution from here, but it didn't help.
I fixed this problem by specifying gem version 0.9.9 in Gemfile:
gem 'rubyzip', "~> 0.9.9"
Using rubyzip (1.0.0) caused an error.
When upgrading rubyzip to 1.0.0 change require 'zip/zip' to require 'zip'.
I had this problem after adding roo to a Rails project.
Roo needed the new interface, something else (some other gem) was using the old interface - so most of these answers didn't work (couldn't lower the version of rubyzip, rubyzip2 is deprecated, didn't have require zip/zip in my project).
What worked for me was cassio-s-cabral's answer referring to the rubyzip github page.
gem 'rubyzip', '>= 1.0.0' # will load new rubyzip version
gem 'zip-zip' # will load compatibility for old rubyzip API.
I had the same problem: error thrown on "require 'zip/zip'" code, and the solution from this post also did not help.
After a long research I found that the problem was that my "require 'zip/zip'" statement was done in a separate
lib/exporters/package_exporter.rb
file, and for some reason "require" statements are not handled in "lib" folder in production by default.
When I moved "require 'zip/zip'" to the beginning of my
app/controllers/packages_controller.rb
the problem was solved!
I had a similar issue with active_support, just added the 'zip' gem to my Gemfile and it worked fine
I'm use rubyzip2 gem to fix this problem
gem 'rubyzip2'
what work for me was to install 2 gems:
gem install rubyzip
gem install zip
and in the script put
require 'rubygems'
require 'zip/zip'
In their github page explains what to do.
Rubyzip interface changed!!! No need to do require "zip/zip" and Zip
prefix in class names removed.
If you have issues with any third-party gems what required old
version of rubyzip you can use next workaround:
gem 'rubyzip', '>= 1.0.0' # will load new rubyzip version
gem 'zip-zip' # will load compatibility for old rubyzip API.

Error while running Metrical

I've a Ruby 1.9.2 and Rails 3.0.9 development environment. When I run the gem "metrical" on my application, I get the following errors:
** Running the specs/tests in the [test] environment
Analyzing: 100% |oooooooooooooooooooooooooooooooooooooooooo| Time: 00:00:00
/Users/tester/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/psych/visitors/emitter.rb:17:in `end_document': undefined method `write' for #<Syck::Emitter:0x000001028d2388> (NoMethodError)
Anyone else seen this issue? I'm out of ideas for the error.
I ran into the same problem, seems to be related to YAML parsing with Ruby 1.9.2
I hacked into metric fu and inserted a explicit requirement of the Psych YAML Engine:
metric_fu-2.1.1/lib/metric_fu.rb:
require 'rake'
require 'psych' # <-- added here
require 'yaml'
And now works...
The simplest solution is to set the RUBYOPT environment variable when you run metrical, so instead of metrical you type:
RUBYOPT='-rpsych' metrical
I am doing that and it's all working fine. This blog post figured it out for me: http://excid3.com/blog/undefined-method-write-for-syckemitter/ (possibly a bit simpler than hacking into metric_fu, until they fix this).

How do I make gemspec dependencies autoload in a Rails 3 app, using a Gemfile

I have a Rails 3 app that I am turning into a Rails engine / gem.
This engine has some gem dependencies that I have put inside it's .gemspec file.
I have created a new 'parent' Rails 3 app, and I would like to add my engine gem to the Gemfile and have the gem's dependencies automatically 'loaded', but this does not work for me! bundle install installs the gem dependencies fine, but when I start the server, the app crashes because they are not loaded.
For example, my engine's gemspec contains these lines:
s.add_runtime_dependency(%q<rails>, ["= 3.0.7"])
s.add_runtime_dependency(%q<acts_as_commentable>, [">= 3.0.1"])
s.add_runtime_dependency(%q<haml>, [">= 3.1.1"])
.. and the parent Rails 3 application has these lines in its Gemfile:
source 'http://rubygems.org'
gem 'my_engine', :path => "~/src/gems/my_engine"
But I get the following error:
undefined local variable or method `acts_as_commentable'
from /home/user/src/gems/my_engine/app/models/account.rb:66:in `<class:Account>'
But if I add gem 'acts_as_commentable', '>= 3.0.1' to the Gemfile of the parent Rails 3 app, then the gem is loaded and the error disappears.
I am using Rails 3.0.8.
Does anyone have any suggestions? Do I need to change something about the way my engine is loading?
During main Rails app boot, Bundler will only require dependencies directly listed in the Gemfile but not any sub-dependencies. It's your library's/Engine's responsibility to require its dependencies when it itself gets required. You can do so using initializers in your Railtie.
class MyRailtie < Rails::Railtie
initializer "require stuff" do
require "stuff"
end
end
In our Rails Engine we used a small trick to require dependencies automatically. Unfortunately you can't specify whether or not they should load in the .gemspec, which would allow for greater control.
Gem.loaded_specs["our_rails_engine"].dependencies.each do |d|
begin
require d.name
rescue LoadError => le
# Put exceptions here.
raise le if d.name !~ /factory_girl_rails/
end
end
I'm looking at Spree (the superhero of Rails Engines!), and they do this in spree_core-0.60.1/lib/spree_core.rb:
require "rails/all"
require 'state_machine'
require 'paperclip'
require 'stringex'
require 'will_paginate'
require 'nested_set'
require 'acts_as_list'
require 'resource_controller'
require 'active_merchant'
require "meta_search"
require "find_by_param"
So the answer is that within your gem, you have to require all of it's gem dependencies one by one. Well, that's how I will do it for now. But please comment if this ever changes in the future.
Seems it don't work, i create a host project and a sub-project with rails 3 engine.
Added the gem to engine's gemspec
s.add_dependency 'simple_form'
then added the require to engine_name.rb like below
require 'simple_form'
But if delete the line [gem 'simple_form'] in host project's Gemfile, it will show undefined immediatly

Rails 3 and vlad the deployer

i couldn't find anywhere if vlad it's compatible with Rails 3, but i tried to deploy a new rails 3 app that we're developing and always returns the same error:
Error loading vlad: no such file to load -- vladrake aborted!
Don't know how to build task 'vlad:init_setup:production'
I'm using ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin9.8.0]
And rails 3.0.1 and i testit with vlad 2.0.0 and vlad 2.1.0
In the Rakefile i have this:
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
require 'rake'
begin
require 'rubygems'
require 'vlad'
Vlad.load :scm => :git, :app => :passenger
rescue LoadError => e
$stderr << "Error loading vlad: #{e}"
end
If anyone has an idea where to look at it in order to fixit or maybe tell me if vlad it's rails 3 ready?
Thanks in advance for your time
Cavi
Maybe you already figured this out, but do you have vlad included in your Gemfile? You probably want to add:
group :development do
gem 'vlad-git'
gem 'vlad'
end
Then run bundle.

Rails 3 Initializers: No such file to load

I am trying to use the Sunlight API gem with a Rails project. I have installed the gem and can successfully use it from irb.
However, when I put the require statement (require 'sunlight') in sunlight.rb in config/initializers, I get the following error:
/opt/local/lib/ruby/gems/1.8/gems/activesupport-3.0.0.beta3/lib/active_support/dependencies.rb:209:in `require': no such file to load -- sunlight (LoadError)
I checked the permissions on the gems directory, and it is world readable/executable.
Here is the code from sunlight.rb:
require 'rubygems'
require 'sunlight'
Sunlight::Base.api_key = 'bb7b775755054c54aa9715d202f6785c'
Can anyone tell me how to fix this? TIA!
Is sunlight listed in your Gemfile? Rails3 uses Bundler to manage Gem installations.
