Allows you to store Ruby BigDecimal as Decimal128 in MongoDB using Mongoid.
Add this line to your application's Gemfile:
gem 'mongoid_decimal', git: 'https://github.com/calleo/mongoid_decimal'And then execute:
$ bundle
Requires MongoDB version 3.4 or later. Don't forget to set feature compatibility version using the Mongo shell:
db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )
Read more about the implications here.
If you have existing BigDecimal fields that are stored as String in Mongo (Mongoid default behavior) you will need to perform a data migration of those fields to Decimal128 for this Gem to work properly.
