ActiveModel :: Serializer：选择JSON编码器

Question

Is there any way to decide which JSON encoder ActiveModel::Serializer uses? It seems that JSON encoding takes forever, and I'd like to try some other encoder.

Answer 1

While Rails won't allow you to do that by default, you can use oj and include this at your Gemfile:

gem 'oj'
gem 'oj_mimic_json'

And it will definitely be faster in these cases.

You can read more about the JSON troubles in Rails below:

• ActiveRecord::Base.extend kills JSON performance
• when freedom patches fight, nobody wins

And while you're at it, run away from ActiveModel::Serializer and just build your own presenter layer to produce the JSON and be happy.
