Ruby新手:未定义的方法`with_indifferent_access' [英] Ruby newbie: undefined method `with_indifferent_access'
问题描述
我是一名新的Ruby程序员,并且是我的一位同事,帮助我开始编写下面的代码,这些代码在他的环境中运行良好.但是,当我尝试在自己的环境中运行它时,出现了以下错误:undefined method 'with_indifferent_access' for #<Hash:0x1012392c0>
(NoMethodError)
I am a new Ruby programmer, and a co-worker of mine to help me get started wrote the following code which ran fine in his environment. However, when I try to run it in my own environment, I ge the follow error: undefined method 'with_indifferent_access' for #<Hash:0x1012392c0>
(NoMethodError)
有问题的方法在代码中出现了两次:
The method in question appears twice in the code:
require 'rubygems'
gem 'activerecord'
gem 'activesupport'
gem 'sailthru-client'
require 'active_support'
require 'active_record'
require 'sailthru'
# Setup our Sailthru object using our production Sailthru account information
sailthru = Sailthru::SailthruClient.new()
# Read database information from the database.yml file
CONFIG = YAML.load_file(File.join(File.dirname(__FILE__), 'database.yml')).with_indifferent_access
# Create a simple way for us to iterate through all publications
class Publication < ActiveRecord::Base
establish_connection CONFIG[:production]
set_table_name 'publications'
end
# Create a simple way for us to store data locally
class CurrentReport < ActiveRecord::Base
establish_connection CONFIG[:development]
set_table_name 'current_reports'
end
class MonthlyReport < ActiveRecord::Base
establish_connection CONFIG[:development]
set_table_name 'monthly_reports'
end
types = %w[Daily Weekly]
Publication.find_each(:select => :id) do |publication|
begin
types.each do |newsletter_type|
# Get the stats for each mailing list
response = sailthru.stats_list("#{newsletter_type} Newsletter - #{publication.id}").with_indifferent_access
if response[:error]
puts "Sailthru Error #{response[:error]}: #{response[:errormsg]}"
else
# Try to find an existing record for this newsletter
daily = CurrentReport.find_or_initialize_by_list(response[:list])
# and update it with the information from the response (minus the monthly signup info)
puts "Updating #{newsletter_type} Newsletter - #{publication.id} ..."
daily.update_attributes(response.reject { |k,v| k =~ /signup/ })
# Iterate through the monthly signup info
response['signup_month'].each do |k, v|
# And try to save it
monthly = MonthlyReport.find_or_initialize_by_list_and_month(response[:list], k)
# Only save new months, because the old months never change
if monthly.new_record?
monthly.update_attributes(v)
puts "\tAdding #{v[:month]} to #{response[:list]} ..."
end
end
end
end
# rescue NoMethodError => e
# puts "Got a NoMethodError for some reason. Here's the publication: #{publication.inspect}\n\nHere's the types array: #{types}"
end
end
我尝试了不同版本的ruby,例如ruby-1.8.7,无济于事.我不知道如何解决这个问题.我知道此方法存在于某处,因为我已经看到它可以工作.我愿意接受任何有关下一步尝试的建议.
I have tried different versions of ruby, such as ruby-1.8.7, to no avail. I am at a loss on how to solve this problem. I know this method exists somewhere because I have seen it work. I am open to any suggestions on what to try next.
推荐答案
尝试使用:
require 'active_support/core_ext/hash'
这实际上是将with_indifferent_access
方法添加到普通Hash类中的原因.
Thats what actually adds the with_indifferent_access
method to the normal Hash class.
