的ActiveRecord :: RecordNotSaved - Rails 3個的播種數據

我正在使用CentOS 5.6rails 3.2.13和ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]。當我嘗試播種數據時，出現以下錯誤。的ActiveRecord :: RecordNotSaved - Rails 3個的播種數據

** Execute Samp:seed:record_status

record_status.rake

16: record_statuses.each do |rs| 
17:  unless RecordStatus.find_by_seed_name(rs[:name]) 
18:  puts "Creating RecordStatus: #{rs[:name]}" 
19:  RecordStatus.create!(:name  => rs[:name], 
20:        :seed_name => rs[:name], 
21:        :description => rs[:description]) 
22:  end 
23:  end

EDIT-1 * RecordStatus.rb *

class RecordStatus < ActiveRecord::Base 
acts_as_enumerated 

ACTIVE = 1 
DISABLED = 2 
DELETED = 3 

    validates_uniqueness_of :id , :name 
end

你有什麼樣的模型驗證對RECORDSTATUS模型？ – apotry

@ peri08我更新了我的問題 – Bathakarai

的Rails 3不支持create/alter/destroy instances由自然枚舉。如果我們想創建的任何枚舉只是record_status.rake文件中添加Model.enumeration_model_updates_permitted = true。 REF：Enumerations_mixin

它看起來像你必須有重複您的種子數據中的名稱。爲了找到肯定，你的電話create!更改爲類似：

rs = RecordStatus.new(...) 
unless rs.save 
    raise "Couldn't save #{rs.inspect}: #{rs.errors.full_messages.to_sentence}" 
end
