Hi! I am using rspec-rails-2.10.1.

When I try to generate any model throughrails generate scaffold/model ..., I get an exception:

[WARNING] Could not load generator "generators/rspec/model/model_generator". Error: uninitialized constant Rspec::Rails::Generators.
    /Users/Kir/Sites/seopl/.bundle/ruby/1.9.1/gems/rspec-rails-2.10.1/lib/generators/rspec.rb:5:in `<module:Generators>'

And then error rspec [not found]

Part of my Gemfile:

group :test, :development do
  gem 'rspec-rails'
  gem "rspec-rails-uncommitted", "~> 2.0"
  gem 'factory_girl_rails'
  gem 'debugger'
  gem 'fivemat'
  gem 'capybara'
  gem 'database_cleaner'
  gem 'spin'

@alindeman alindeman Explicitly specify the scope of Rails
* If another gem defines `Rspec::Rails` before us, `Rails` might qualify
  to `Rspec::Rails` (at least in 1.9)
* Fixes #555

Thanks for the report! I think this occurs in the case that Rspec::Rails is defined before rspec-rails loads. This may be because of rspec-rails-uncommitted, though the bug is with us.

I've committed a fix: can you try it out by using the master branch of rspec-rails? In your Gemfile:

gem 'rspec-rails', github: 'rspec/rspec-rails'


$ bundle update rspec-rails

Now it works! Thank you!


Great: this will be released with the next version of rspec-rails.
