Rails Tip: How to Update Attributes Without Save

Feb 17th, 2015 3:31 pm

generally, when we use update_attributes, it will save automatically. however, what if we just want to new an record and update some attributes of it. what can we do?
We can use assign_attributes method.

user = User.new
user.assign_attributes({ :name => 'Andy'})
user.name        # => "Andy"
user.new_record? # => true
