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(:name => "t")

How i can save it at once?

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.

a.each(&:save)

This will call B#save on each item in the array.
