rails 3.0.1 active_record

Question

How is it possible with active_record?

u = User.all
u = u.where(:id => 1)

NoMethodError: undefined method `where' for # u.class => Array

Can't chain conditions :(

Answer 1

The all method executes the query. So you can't chain after using it.

u = User.where(:id => 1)
u.where(:id => 2)

This would execute the query WHERE id = 1 AND id = 2
