Question

我跑：

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

并获得：

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'
...

full error output ......有谁知道这里发生了什么？

我的意思是它的.rb文件，其中包含看起来像ERB代码的内容：

<%= module_namespacing do - %>

导致文件错误：

看起来名为'generator-parent-option'的边缘分支将起到作用：

#/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

并得到了很好的清洁输出：

undefined方法：使用mongo_mapper的Rails 3.0.11生成器
