我是新來的Rails,但我需要在我的應用程序運行Ruby 1.9.2和Rails 3使用複合主鍵。我無法獲得組合鍵正常工作在我的Ruby on Rails應用程序中。我跟着the compositekeys site的方向,但我仍然得到同樣的錯誤: 沒有這樣的文件來加載 - composite_primary_keysRuby錯誤沒有這樣的文件加載 - composite_primary_keys
1 - sudo的創業板安裝composite_primary_keys
2 - 在末尾添加需要「composite_primary_keys」通過conf/environment.rb文件中
3 - 增加了set_primary_keys
我的寶石名單如下:
abstract (1.0.0)
actionmailer (3.0.1)
actionpack (3.0.1)
activemodel (3.0.3, 3.0.1)
activerecord (3.0.1)
activeresource (3.0.1)
activesupport (3.0.3, 3.0.1)
arel (2.0.3, 1.0.1)
builder (2.1.2)
bundler (1.0.3)
composite_primary_keys (2.3.5.1)
我的領域類看起來是這樣的:
class Radioreport < ActiveRecord::Base
set_primary_keys :service_id, :date_id
belongs_to :report_date, :foreign_key => "date_id"
belongs_to :service, :foreign_key => "service_id"
...
而且我的環境文件看起來像這樣:
rake aborted!
no such file to load -- composite_primary_keys
單元測試是:
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
Upreports::Application.initialize!
require 'composite_primary_keys'
的錯誤,我得到的是,當我跑我的「耙測試」以下:
require 'test_helper'
require 'rubygems'
require 'composite_primary_keys'
class RadioreportTest < ActiveSupport::TestCase
fixtures :radioreports, :services, :genres, :groups, :locations, :report_dates
def setup
@radioReport = Radioreport.new
end
def test_should_put_all_radios_and_totals_in_a_hash
transactions = Radioreport.find(:all)
reportTransactions = @radioReport.getRadioTotalsByDayMap(transactions)
assert_not_nil(reportTransactions)
assert_equal(2, reportTransactions.size)
previousKey = nil
previousValue = nil
reportTransactions.each{|key, value|
if(previousKey == nil || previousValue == nil)
previousKey = key
previousValue = value
else
assert_not_nil(key)
assert_not_equal(previousKey, key)
assert_not_nil(value)
assert_not_equal(previousValue, value)
end
}
end
我查了下thread,但這個不適用。我已經檢查過我的耙子,寶石等。
謝謝你們! ;)
