Heroku + Rails + GeoIp =未初始化的常量GeoIP错误

问题描述 投票：0回答：1

我正在尝试将旧网站部署到Heroku。一切顺利，开始了，但是当我通过网络浏览器访问它时，我得到

NameError (uninitialized constant ApplicantsController::GeoIP):

我正在使用Rails 2.3.18（我的网站非常简单，只想“按原样”部署它并尽快；在专用服务器上，一切正常。]]

我在'db'文件夹中以及我在controllers / applicants_controller.rb中有一个GeoIP.dat文件

line 32:    geoip ||= GeoIP.new("db/GeoIP.dat")
line 33:    location = geoip.country('google.com')

如果我在Heroku上启动irb，一切看起来都不错：
login@sancho:~$ heroku run bash
Running `bash` attached to terminal... up, run.7785
~ $ irb
irb(main):001:0> require 'geoip'
=> true
irb(main):002:0> geoip ||= GeoIP.new("db/GeoIP.dat")
=> #<GeoIP:0x00000002b3a6a8 @mutex=#<Mutex:0x00000002b3a680>, @flags=0, @database_type=1, @record_length=3, @file=#<File:db/GeoIP.dat>, @database_segments=[16776960]>
irb(main):004:0> geoip.country('google.com')
=> #<struct GeoIP::Country request="google.com", ip="74.125.228.110", country_code=225, country_code2="US", country_code3="USA", country_name="United States", continent_code="NA">
irb(main):005:0> 

这里是完整的错误日志。
