How can I have ActiveRecord's pluck also return the column name for rendering in json?

Question

def jsontest
   @users = User.all.limit(10)
   render json: @users
end

yields

{
...

\"id\": 7,
\"name\": \"Sage Smith\",
\"email\"         


        

Answer 1

@girishso's gem is great, but my project is in Rails 3. It doesn't work.

This article is helpful to me, or install pluck_all gem to achieve this.

Usage:

User.limit(10).pluck_all(:id, :name, :email, :created_at)
