Hello everyone :) I need to access an attribute directly into a find. Is that possible? For instance: Topics.find(:all, :conditions => expiration_date-1.hour + " < NOW( )") Here, expiration_date would be an attribute of Topics. Thank you !

I think you'd do something like this: Topics.find(:all, :conditions => ["expiration_date < ?", Time.now + 1.hour]) See http://www.railsbrain.com/api/rails-2.2.2/doc/inde... more examples. Regards, Craig -- Craig D. Mutually Human Software http://mutuallyhuman.com

It helps, thanks! But what if I have 2 conditions ? For instance, is this possible? Topics.find(:all, :conditions => ["expiration_date < ? AND attribute =", Time.now + 1.hours], yet_another_variable) Thank you!

Topic.find(:all, :conditions => ["expiration_date < ? AND attribute = ?", Time.now + 1.hour, yet_another_variable]) In other words, everything goes in the conditions array. The first element is the SQL fragment. Every other element is a value to be substituted for a ? in the SQL fragment. Rails will properly quote strings and dates. Again, see the find docs [ http://www.railsbrain.com/api/rails-2.2.2/doc/inde...] for examples. Also, the Rails Guides [ http://guides.rubyonrails.org ] are good, and the section on query conditions [ http://guides.rubyonrails.org/active_record_queryi... ] has more details.
