# activerecord-import
|
||||
|
||||
activerecord-import is a library for bulk inserting data using ActiveRecord. By default with ActiveRecord, in order to insert multiple records you have to perform individual save operations on each model, like so:
|
||||
|
||||
10.times do |i|
|
||||
Book.create! :name => "book #{i}"
|
||||
end
|
||||
|
||||
This may work fine if all you have is 10 records, but if you have hundreds, thousands, or millions of records it can turn into a nightmare. This is where activerecord-import comes into play. Here's the equivalent behaviour using the #import method:
|
||||
|
||||
books = []
|
||||
10.times{ |i| books << Book.new(:name => "book #{i}") }
|
||||
Book.import books
|
||||
|
||||
Pretty slick, eh?
|
||||
|
||||
Maybe, just maybe you're thinking, why do I have do instantiate ActiveRecord objects? Will that perform validations? What if I don't want validations? What if I want to take advantage of features like MySQL's on duplicate key update? Well, activerecord-import handles all of these cases and more!
|

For more documentation on the matter you can refer to two places:

||||
1. activerecord-import github wiki: http://wiki.github.com/zdennis/activerecord-import/
|
||||
1. the tests in the code base
|
||||
|
||||
Note: the tests have been updated since the previous version of ar-extensions to provide better readability and easier maintenance.
