SettingsLogic不工作2.3

運行一些單元測試（使用包含的Ruby/Rails測試::單位模塊）調用使用一些SettingsLogic特徵的方法，當我得到這個錯誤：SettingsLogic不工作2.3

RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id

更具體地說，我寫了一些單元測試，以測試我的模型中的一些方法。這些方法使用SettingsLogic功能，但似乎在這裏發生了錯誤。我運行測試控制檯並檢查Settings類是否已定義。但是，我無法訪問我的設置值哈希值。

script/console test 
Loading test environment (Rails 2.3.10) 
DEPRECATION WARNING: require "activesupport" is deprecated and will be removed in Rails 3. Use require "active_support" instead. (called from /var/lib/gems/1.8/gems/activesupport-2.3.10/lib/activesupport.rb:2) 
>> Settings 
=> Settings 
>> Settings.blah 
RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id 
    from (erb):32 
>> exit

而在開發環境中，我得到：

script/console 
Loading development environment (Rails 2.3.10) 
>> Settings 
=> Settings 
>> Settings.blah 
=> {"gadget_type"=>{"alarm_history_table"=>{"max_printable_rows"=>200, "max_visible_rows"=>14, "_id"=>5, "rows_per_page"=>100}, "text"=>{"_id"=>2}, "current_state_table"=>{"max_printable_rows"=>200, "max_visible_rows"=>14, "_id"=>1, "rows_per_page"=>10}, "column_based_history_table"=>{"max_printable_rows"=>200, "max_visible_rows"=>14, "_id"=>6, "rows_per_page"=>100, "related_states"=>{"unit"=>17, "description"=>49}}, "entity_history_table"=>{"max_printable_rows"=>200, "max_visible_rows"=>14, "_id"=>4, "rows_per_page"=>100}, "chart"=>{"_id"=>3}, "access_type"=>{"url"=>1, "file"=>2}}} 
>> exit

我手動運行測試，即不與耙試驗，但與ruby unit/my_model_test.rb

的settings.rb模型如下：

class Settings < Settingslogic 
    source "#{Rails.root}/config/application.yml" 
    namespace Rails.env 
end

而application.yml設置文件：

defaults: &defaults 
    blah: 
    gadget_type: 
     access_type: 
     url: 1 
     file: 2 
     current_state_table: 
     _id: 1 
     max_visible_rows: 14 
     rows_per_page: 10 
     max_printable_rows: 200 
     text: 
     _id: 2 
     chart: 
     _id: 3 
     entity_history_table: 
     _id: 4 
     max_visible_rows: 14 
     rows_per_page: 100 
     max_printable_rows: 200 
     alarm_history_table: 
     _id: 5 
     max_visible_rows: 14 
     rows_per_page: 100 
     max_printable_rows: 200 
     column_based_history_table: 
     _id: 6 
     max_visible_rows: 14 
     rows_per_page: 100 
     max_printable_rows: 200 
     related_states: 
      description: <%= Property.find_by_name('description').id %> 
      unit: <%= Property.find_by_name('units').id %> 

development: 
    <<: *defaults 

test: 
    <<: *defaults 

production: 
    <<: *defaults

FIXED

的問題是在YAML嵌入式紅寶石：

Property.find_by_name('description').id

我沒有屬性燈具所以對於這個原因，它失敗了。
