Upgrade to 1.9 notes

Upgrade "the second project" to ruby 1.9 notes

Gems

Keep in mind that not all gems (versions) support a needed ruby version.

• Remove 1.8 gems: rcov, ruby-debug
• Add 1.9 gems: debugger

Try 'bundle install'.

Encoding

In ruby 1.9 you should add encoding manually:

# encoding: UTF-8

CSV

• Remove 'fastercsv' gem from the dependencies becasue of it's a part of the standard libraries now.
• Use 'CSV.generate' instead of 'CSV::Writer.generate'

Differences in syntax

• Use 'then' in Case "when 'expected' then 'result'" instead of "when 'expected': 'result'"
• Hash notation with comma are not supported: { key, value }

Array building

:to_s works as :inspect now:

1.8.7 :001 > ['1','2','3'].to_s
 => "123"

1.9.3-p286-perf :001 > ['1','2','3'].to_s
 => "[\"1\", \"2\", \"3\"]"

So, replace your custom message buildings:

entry.errors[:column]

with:

entry.errors[:column].join(', ')
