ruby-on-rails-3 - 未定义的方法：使用 mongo_mapper 的 Rails 3.0.11 生成器

Question

我跑：

$ rails g scaffold User first_name:string last_name:string email:string website:string nodes:array links:array --orm=mongo_mapper

并得到：

invoke  mongo_mapper
create    app/models/user.rb
(erb):1:in `template': undefined method `module_namespacing' for #<MongoMapper::Generators::ModelGenerator:0x000000035cd4a8> (NoMethodError)
...
from /home/thrive/.rvm/gems/ruby-1.9.2-p290@mlrepo/gems/mongo_mapper-0.11.1/lib/rails/generators/mongo_mapper/model/model_generator.rb:17:in `create_model_file'
...

完整的错误输出...有人知道这里发生了什么吗？

我的意思是它是一个 .rb 文件，其中看起来是 ERB 代码：

<%= module_namespacing do - %>

导致文件的错误：

• 模型生成器.rb
• 模型.rb

看起来名为“generator-parent-option”的边缘分支可以解决问题：

#/Gemfile
gem 'mongo_mapper', :git => 'git://github.com/bearded/mongomapper.git', :branch => 'generator-parent-option'

我跑了：

$ rails g scaffold User first_name:string last_name:string email:string website:string nodes:array links:array --skip-migration --orm=mongo_mapper

并得到了干净的输出：
