Ruby 1.8.7 compatibility

I had a exception when I switch to Ruby 1.8.7 on Snow Leopard

ArgumentError: wrong number of arguments (1 for 0)

Application uses Rails 1.2.5: there is no chance to update rails in this app. Somebody have solution?

There will be a lot of compatibility issues with such an old version of rails and ruby 1.8.7. I would suggest using rvm to install multiple ruby versions / rails versions to test your app. I would also look into security patches as I am not sure if they are being backported to the 1.2.x branches.

I put this in a file inside config/initializers

class ::DateTime

alias_method :to_s, :to_formatted_s

end
