我在seeds.rb文件下面的代碼在JRuby中1.6.3軌道3.1項目，我用耙分貝調用：種子的find_by_sql在Rails 3.1
Role.destroy_all
User.destroy_all
["admin", "standard"].each do |role|
Role.find_or_create_by_name(role)
end
if User.find_by_email("[email protected]").nil?
user = User.new
user.email = "[email protected]"
user.password = "Passw0rd"
user.password_confirmation = "Passw0rd"
user.role = Role.find_by_name("admin")
user.save!
end
if User.find_by_email("[email protected]").nil?
user = User.new
user.email = "[email protected]"
user.password = "bonjovi5"
user.password_confirmation = "bonjovi5"
user.role = Role.find_by_name("standard")
user.save!
end
當我運行耙分貝：種子 - -trace，我得到以下堆棧跟蹤：
** Invoke db:seed (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:abort_if_pending_migrations
** Execute db:seed
rake aborted!
wrong number of arguments (3 for 2)

這個用來工作，任何人都可以做到底是怎麼回事的任何意義嗎？我的gemfile看起來像這樣：
source 'http://rubygems.org'
source 'http://gems.engineyard.com'
gem 'rails', '~> 3.1.0.rc5'

end

end

end
任何幫助非常感謝。
你能準確的說出種子行3和233的含義嗎？堆棧跟蹤指向他們，但我不知道他們是誰。謝謝！ –
btw是什麼意圖：[「admin」，「standard」]。每個do | role | Role.find_or_create_by_name（role） end它似乎圍繞着這些項目（管理員和標準），併爲每個做一個查找，但沒有做任何事情，它沒有分配給任何東西，直接（=）或追加（<<）？ –
從它的外觀我會說你要麼在Rails上找到bug，要麼在JDBC ActiveRecord適配器上找到bug。 –
