Redmine

I replaced the “lang_options_for_select” code wiht the old one（from 1.2.1）， and it works just fine，can any one tell me why？

I am not familiar with ruby or rails...

Problem solved.

Update ruby from 1.8.7 to 1.9.3, error gone.

or

Replace the "lang_options_for_select" code at application _helper.rb with old version:

 def lang_options_for_select(blank=true)
-    (blank ? [["(auto)", ""]] : []) + languages_options
+    (blank ? [["(auto)", ""]] : []) +
+     valid_languages.collect{|lang| [ ll(lang.to_s, :general_lang_name), lang.to_s]}.sort{|x,y| x.last <=> y.last }
 end

The same problem when i click on setting in ADministration:

The answer is one post above your own post. It starts with the words "Problem solved".

When I had installed Ruby 1.9.3-p374, the new problem is:

A source file that the application requires, is missing.

    It is possible that you didn't upload your application files correctly. Please check whether all your application files are uploaded.
    A required library may not installed. Please install all libraries that this application requires.

Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

Error message:
    Please install the mysql adapter: `gem install activerecord-mysql-adapter` (mysql is not part of the bundle. Add it to Gemfile.)

I typed: gem install activerecord-mysql-adapter
successed

But problem not gone :(

The problem is on my file config/database.yml, edit it and change

adapter: mysql

adapter: mysql2

Problem is gone!

thanks.
