Forum: IronRuby Error with Rails and DBI::Date

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 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.
