Redmine

Now, trying to update an issue, I also get an "Internal server eror":

You have a mismatching configuration:

Rails2.0.2 with Ruby 1.8.6 OK
Rails2.1 with Ruby 1.8.7 Ok
Rails2.0.2 with Ruby 1.8.7 == BAD BAD BAD!

I recommand you to upgrade your rails version.

$ ruby --version
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux]
$ rails --version
Rails 2.1.0

I stopped and restarted Redmine. But still, when I try a search, I see this in the production.log:

Is more of the log helpful? Should I reinstall Redmine too after the rails upgrade? Can the database be salvaged, or will it need to be scratched as well if so?

Thanks for any pointers,

Bjorn.

Just to be sure:

Are you running redmine through fcgi or mod_rails? In that cases, just restarting web server isn't enough: you have to kill each fcgi/mod_rails processes before starting the server.

In each other cases, this combinaison of rails and ruby should work like a charm under redmine 0.7.3

There is said to be a solution for this (http://www.redmine.org/issues/show/1609) but that doesn't work for me. I have the same configuration as you have. Could you try this and see what happens?

I imagine that you have a parasite ruby or rails stack or more probably: an ancient rails version frozen in your redmine.
From your redmine directory, please run this command:

rake rails:unfreeze

Then restart your server and test it again.

I did the solution suggested by Maarten, i.e. replace the "truncate" method inside the Rails vendor directory, and that made things work again. It seems Rails is included in Redmine inside the vendor/rails directory, so as such the suggestion from Thomas would seem like a good one, but when I tried that Redmine stopped working altogether.

I ended up installing Redmine from SVN, and I'm now a happy Redmine camper again - search and all.

Thanks for your help!

Bjorn.
