save an active records array

Question

I have an array like this

a = []

a << B.new(:name => \"c\")
a << B.new(:name => \"s\")
a << B.new(:name => \"e\")
a << B.new(:n         


        

Answer 1

B.transaction do
  a.each(&:save!)
end

This will create a transaction that loops through each element of the array and calls element.save on it.

You can read about ActiveRecord Transactions and the each method in the Rails and Ruby APIs.
