How to insert multiple records in rails3.0

Question

In rails3.0 how to insert multiple records in a table? plz tell me any example application.

Answer 1

You can use transactions

titles = ["T-Shirt", "Boots", "Cap"]

ActiveRecord::Base.transaction do
  titles.each do |title|
    Thing.create(:title => title)
  end
end

Ot make one sql query:

query = []
titles.each do |title|
  query << "('#{title}')"
end
sql = "INSERT INTO things ('title') VALUES #{query.join(", ")}"
ActiveRecord::Base.connection.execute(sql)
