如何使用Oracle配置Ruby on Rails？

Question

网上有几个讨论这个问题的网页,但大多数都是以某种方式过时或不准确的.

什么是独家新闻？

Answer 1

建造红宝石,宝石和铁轨

根据http://rubyonrails.org/download:

build ruby
build gem
use gem to install rails

获取Oracle Instantclient

从http://www.oracle.com/technology/tech/oci/instantclient/index.html下载

您的架构需要这两个包.

instantclient-basic
instantclient-sdk

解压缩这些文件,并建立此链接

cd instantclient_10_2
# .dylib for mac, .so for linux
ln -s libclntsh.dylib.10.1 libclntsh.dylib

建立ruby-oci8

注意,JRuby用户不需要ruby-oci8,但是需要Oracle JDBC jar,ojdbc6.jar或ojdbc5.jar,具体取决于你是使用Java 6还是Java 5.

从http://ruby-oci8.rubyforge.org/en/index.html下载并运行

# DYLD for mac
export DYLD_LIBRARY_PATH=/path/to/instantclient_10_2
# LD for linux
export LD_LIBRARY_PATH=/path/to/instantclient_10_2
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

使用此行和数据库连接字符串进行测试.

ruby -r oci8 -e "OCI8.new('scott/tiger@orcl').exec('select * from user_tables') do |r| puts r.join(','); end"

安装activerecord-oracle_enhanced-adapter

注意,不是 像许多旧页面提到的activrecord-oracle-adapter.

gem install activerecord-oracle_enhanced-adapter

做那个甜美的东西吧

rails railstest
cd railstest
# edit config/database.yml as below
ruby script/generate scaffold comic title:string issue:integer publisher:string
rake db:migrate
ruby script/server

在浏览器中测试

<http://localhost:3000/comics>

配置/ database.yml的

如果您有TNS条目,请使用数据库,否则使用主机.请注意,您有三个要更新的条目(devel,test,production).

development:
    adapter: oracle_enhanced
    database: orcl           # format is tns-name entry
    host:  myorclhost/orcl   # format is hostname/instance-name
    username: scott
    password: tiger
