Hey, thanks for the patch. Rubygems (1.3.5) was complaining about an "illformed requirement", which I fixed by replacing the first line with:

if Rails.version == '2.3.8' && Gem.available?('mongrel', '~>1.1.5') && self.class.const_defined?(:Mongrel)

EDIT: Thanks for the correct fix, bshand.

bshand commented

I "fixed" it for Rubygems 1.3.5 with the following first line:

if Rails.version == '2.3.8' && Gem.available?('mongrel', '~>1.1.5') && self.class.const_defined?(:Mongrel)

stangel commented

This seems to also be a problem in Rails 2.3.9 so I changed the first line to:
if ['2.3.8','2.3.9'].include?( Rails.version ) && Gem.available?('mongrel', Gem::Requirement.new('~>1.1.5')) && self.class.const_defined?(:Mongrel)

dumbledore commented

the same with Rails 2.3.10

vivek-dhayalan commented

When I use this above code I am getting undefined method 'alias_method_chain' for #Class:Mongrel::CGIWrapper. I am newbie to rails please help me. Thanks in advance.

stangel commented

Vivek a couple suggestions:
1. If you're using Rails 3 then alias_method_chain is deprecated, but you shouldn't need this patch on Rails 3.
2. If you're on a Mac you might try this: http://john.vipvip.com/blog/?p=71

vivek-dhayalan commented

I am using rails 2.3.8 only. But still I am facing this problem.

metaskills commented

@vivek-dhayalan Perhaps you are not loading this file at the right time. I have it in my 2.3.8 app in lib/initializers/mongrel.rb

vivek-dhayalan commented

I have moved my file to location as said and I have added the following two lines in environment.rb

require File.join(File.dirname(File.expand_path(FILE)), '../lib/initializers/mongrel')
config.gem "mongrel"

but, I am getting the same error again.

metaskills commented

Crap, a mistake on my part, I meant config/initializers/mongrel.rb.

Also, do not require the file, rails requires init file automatically.

vivek-dhayalan commented

thanks, it worked.

rca commented

Thanks for the fix. I've put together a patched gist that fixes the issues in the comments below that works for Rails versions ['2.3.8', '2.3.9', '2.3.10', '2.3.11']:

Thanks.

stangel commented

Eduardo, what does E:/webSAS/webSAS/vendor/plugins/recode_legacy_database/lib/recode_legacy_database.rb line 36 look like?

edusilva commented

is a plugin that work with encoding utf-8 to iso, its useful for use rails with sqlserver old versions. it converts caracters encoding when saving and loading data from database to ensure that special caracters will be displayed correctly.

edusilva commented

thnks for the tip
