How do I build a JSON object?

Question

Currently I build a JSON object by doing:

@users = User.all

@users.each do |user|
  @userlist << {
    :id => user.id,
    :fname => user.fname,
            


        

Answer 1

  @userlist = @users.map do |u|
    u.attributes.merge!(:contacts=>current_user.contacts)
  end
  json = @userlist.to_json
