PluckAll

Pluck multiple columns/attributes in Rails 3, 4, 5, and can return data as hash instead of only array.

If you have a Rails 3 project, and want to pluck not only one column, feel free to use this gem and no need to worry about upgrading to Rails 4, 5 in the future will break this.

Usage

pluck to array

Behaves the same as the Rails 4 pluck, but you can use it in Rails 3

User.where('id < 3').pluck_array(:id, :account)
# => [[1, 'account1'], [2, 'account2']]

pluck to hash

Similar to pluck_array, but return hash instead.

User.where('id < 3').pluck_all(:id, :account)
# => [{"id"=>1, "account"=>"account1"}, {"id"=>2, "account"=>"account2"}] 

User.where('id < 3').pluck_all('id, account AS name')
# => [{"id"=>1, "name"=>"account1"}, {"id"=>2, "name"=>"account2"}]
