Installation
Requires Postgresql 9.5+
ActiveRecord >= 4.2 supported and tested.
Add this line to your application's Gemfile:
gem 'activerecord_mass_insert'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install activerecord_mass_insert
Usage
class ApplicationRecord < ActiveRecord::Base
self.abstract_class = true
extend ActiveRecord::MassInsert::Helper
end
class Dog < ApplicationRecord
end
payload = '[{"name":"Madison","breed":"Golden","meta":{"rescue":false,"age":null}},{"name":"Daisy","meta":{"rescue":true,"age":18}},{"name":"Gracey","meta":{"rescue":false,"nickname":"Scoogie","age":11}},{"name":"Sadie","meta":{"rescue":true,"dingo_blood":true,"age":11}},{"name":"Raymond","meta":{"rescue":null,"nickname":"Radar","tail":false,"age":11}},{"name":"Nemo","meta":{"rescue":true,"number_of_ears":1,"age":2}}]'
dog_ids = Dog.mass_insert(payload)
dogs = Dog.find(dog_ids)
puts dogs.count # => 6
puts dogs.first.name # => Madison
puts dogs.first.breed # => Golden
puts dogs.first. # => { "rescue" => false, "age" => null }
For a payload you can pass a JSON objects by itself, in a JSON array, or a ruby array. You can also pass a ruby object that responds to to_json by itself or in an array. nil payload is treated as an empty json array. JSON will never be parsed to ruby. This done to ensure no time is wasted parsing json twice.
