[rails] undefined method `handling_predicate!'

drsharp · January 21, 2010, 4:04am

I’m trying to use authlogic and factory_girl with rspec and I am
getting an error I don’t understand. Basically I have this failing
spec:

it “should succeed in creating a user from a factory” do
testuser = Factory.create(:user)
debugger
testuser.should be_valid
end

When I stop in the debugger I see this:

(rdb:1) testuser.valid?
true
(rdb:1) testuser.should be_valid
NoMethodError Exception: undefined method `handling_predicate!’ for
#<Spec::Matchers::Be:0x25a9cac @args=[:be_valid]>

My (limited) understanding of rSpec is that if the “testuser.valid?”
works then “testuser.should be_valid” should work as well. I’m
confused because its not working.

Can someone help me understand what is going on here?

I am using the following gem versions:
rspec (1.3.0)
rspec-rails (1.3.2)
authlogic (2.1.3)
factory_girl (1.2.3)
rails (2.3.5)

I have uninstalled/ reinstalled rspec, rspec-rails and rerun
script/generate rspec letting it overwrite everything.

Gist with full terminal output from running the spec and files:

users.rb

Factory.define :user, :class => User do |u|
  u.username "joe"
  u.password "blow"
  u.password_confirmation "blow"
  u.email "[email protected]"
end

Factory.define :invalid_user, :class => User do |u|
end

user_spec.rb

require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')

 describe "using factory created user" do
    it "should succeed in creating a user from a factory" do
      testuser = Factory.create(:user)
      testuser.should be_valid
    end
  end
end

spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.dirname(__FILE__) + "/../config/environment" unless defined?(RAILS_ROOT)

require 'factory_girl'

Spec::Runner.configure do |config|
  config.use_transactional_fixtures = true
  config.use_instantiated_fixtures  = false

There are more than three files. show original

spec/models/user_spec.rb
spec/spec_helper.rb
spec/factories/users.rb

Hey Dan,

If you’re seeing that error it means you have an older version of
rspec-rails than 1.3.2 that is being loaded. Try running the spec with
–backtrace so you can see a full backtrace. Do you see any other
versions being loaded? Maybe from vendor/plugins?

David,

That indeed was the problem. The gist from the original post shows
the test run with --backtrace and it does show rspec-rails in vendor/
plugins (I didn’t see a version number tho). I did the following:
rm -fr vendor/plugin/rspec-rails
rm -fr vendor/plugin/rsecp
sudo gem install rspec rspec-rails

After which the spec no longer produces a NoMethodError and in fact
passes.

Thanks for taking the time to help me understand this, I was really
stuck.

Dan
