Hi guys,

I’m on a new computer and I’m trying to run rails (via IronRuby) for the  
first time here.  
I have installed the rake, rails and activerecord-adonet-sqlserver gems,  
added the config.gem line to environment.rb and updated the database.yml  
file.

As soon as I try to run the WEBrick I get the next exception:  
‘alias\_method’: undefined method `public' for class`DBI::Date’  
(NameError)

This is caused because of line 57 in the date.rb file of the DBI gem:  
deprecate :initialize, :public

I replaced the DBI gem with Ivan’s Ironruby-dbi gem but it didn’t help.

Has anyone run into this problem?

Thanks,  
Shay.

It turned out to be some kind of a gem versions mess… Had to uninstall  
several gems and reinstall them to get it going.

Hi Shay,

I am facing the same problem. Could you find out which versions of these  
gems you need to reinstall? Here is my list:

Successfully installed deprecated-3.0.0  
Successfully installed dbi-0.4.3  
Successfully installed dbd-adonet-0.3.2  
Successfully installed dbd-adonet-sqlserver-0.3.2  
Successfully installed activerecord-sqlserver-adapter-2.3.1  
Successfully installed activerecord-adonet-sqlserver-0.3.4

I am running rails 2.3.8, btw.

Cheers,  
Jack

I’ve reinstalled IR since then so I don’t have the list now. I remember  
it  
was something with the deprecated gem… try to install a previous  
version  
of it.

Not sure though. I’ll have time to look into it only in a few days.  
Has someone here run into this problem, fixed it and have the solution  
at  
hand?

Shay.

activerecord-sqlserver-adapter now supports IronRuby directly, and does  
not  
depend on any of the DBI gems (I update  
[http://ironruby.net/documentation/rails](http://ironruby.net/documentation/rails) a while ago with this). Try just  
installing activerecord-sqlserver-adapter-2.3.8 without any of those DBI  
gems, as they might be doing something incompatible with DBI::Date.

I had a similar problem on a machine that had deprecated version 3.0.0  
on it. I uninstalled it (it also had version 2.0.1 that is on the rest  
of my machines) and the problem was resolved.
