Redmine

Sorry for being somewhat late ....

I'm somewhat overwhelmed with project work, so our redmine incarnation is not very up-to-date - means I'm at 1.3.1stable here.

I've checked on that anyhow, because it's way more current than the version the problem was reported for (1.0.1). The problem ist definitely there on V1.3.1.

I've opened a group's user list, and found the following sort order (names shortened ...)

Fi...
Ge...
Gi...
Gl...
Go...
Gr...
Gä... (wrong position)
Gü... (wrong position)
Ha...
He...
Hi...
Ho...
Hä... (wrong position)
Ig...

Could anybody from DE locale please check that with the current version ?

In v2.2 everything is fine.

Ruby 1.8 or 1.9?

Ruby 1.8 or 1.9?

ruby 1.9.1

Update: Only in the admin settings the group list is sorted correctly. When I want to add a group as a member to a project (in the project settings) the list is not correct!

Hint: In the german language the sorting of ä is equal to a. (ö=o, ü=u)

This problem is somehow "unfixable", as there is no silver bullet.

By choosing one collation, you will "fix" it for one language, but break it for another one, because that's what collations are made for, to solve the problem of ordering characters.

Maybe the best sollution could be to high awareness of collations and help new users figure out what is the correct one they should use to support their languages.

(sorry, had to split it in two answers as redmine "flaged" as a possible spam)

Redmine/Rails could handle ORDER BY .. COLLATE part depending on user profile?

The problem seems to be more with ruby #sort:

Using the database sort (MySQL):

irb(main):002:0> Group.sorted.all.map(&:name)
  ←[1m←[35mGroup Load (0.0ms)←[0m  SELECT `users`.* FROM `users` WHERE `users`.`
type` IN ('Group') ORDER BY users.lastname ASC
=> ["Gä", "Gr", "Gü"]

Using ruby #sort (1.9.3):

irb(main):003:0> Group.all.map(&:name).sort
  ←[1m←[36mGroup Load (0.0ms)←[0m  ←[1mSELECT `users`.* FROM `users` WHERE `user
s`.`type` IN ('Group')←[0m
=> ["Gr", "Gä", "Gü"]

Because it uses a SQL ORDER

When I want to add a group as a member to a project (in the project settings) the list is not correct!

In 2.2, groups are sorted using ruby #sort for when adding a project member. Since 2.3, it uses a SQL ORDER statement so it should be OK now.

I had the same problem on edit/add issue page and https://github.com/twitter/twitter-cldr-rb#sorting-collation help me.
I added this twitter_cldr gem to Gemfile.local and modify
