Hello,

i just installed the plugin validates\_date\_time:

C:\Programme\InstantRails\InstantRails\rails\_apps\LPP\>ruby script/plugin  
install [http://svn.viney.ne](http://svn.viney.ne)  
t.nz/things/rails/plugins/validates\_date\_time/

- ./validates\_date\_time/CHANGELOG
- ./validates\_date\_time/MIT-LICENSE
- ./validates\_date\_time/README
- ./validates\_date\_time/Rakefile
- ./validates\_date\_time/init.rb
- ./validates\_date\_time/lib/multiparameter\_attributes.rb
- ./validates\_date\_time/lib/parser.rb
- ./validates\_date\_time/lib/validates\_date\_time.rb
- ./validates\_date\_time/test/abstract\_unit.rb
- ./validates\_date\_time/test/database.yml
- ./validates\_date\_time/test/date\_test.rb
- ./validates\_date\_time/test/date\_time\_test.rb
- ./validates\_date\_time/test/fixtures/people.yml
- ./validates\_date\_time/test/fixtures/person.rb
- ./validates\_date\_time/test/schema.rb
- ./validates\_date\_time/test/time\_test.rb

Seems like a success,but when i list  
gem list  
the plugin is not listed, that goes along with the problem that when i  
try to use validates\_date :date\_of\_birth (a valdiation method which now  
should be useable) in my model, i get the error “undefined method”

but why is this so?

thanks

Well, this is even more disturbing.  
After gems clean and an update of rails version 1.2.3 it works fine now.  
Hm…  
Thanks anyway.
