ActiveModel Serailizers, how can I load it and why do I need to?

Rails
1

Noobie here.

The gist of my problem is this. If I move from serializer file from
app/serializers/ to app/models/ then everything works fine. My JSON API
will output my data according to my serializer. However, if I remove the
copy from the app/models/ directory… it no longer works and goes back
to Rails default JSON output.

What do I need to do to include my serializer file in app/serializers/?

/app/serializers/item_serializer.rb

class ItemSerializer < ActiveModel::Serializer
  attributes :id, :name
end

/app/controllers/items_controller.rb

class ItemsController < ApplicationController
  respond_to :json

  def index
    items = Item.all
    respond_with ({ success: :true, items: items }.as_json)
  end

  def show
    @item = Item.find_by_id(params[:id])
    if @item
      render json: @item, serializer: ItemSerializer
    else
      render json: { success: :false, error: "Could not find

item."}, status: :not_found
end
end
end

Do I HAVE TO have my serializers in /app/models by default. Why would
ActiveModel Serializers default generating a new serializer then to the
/app/serializers directory. How do I let my controller know about my
serializer?

I’m not sure exactly what you are trying to do, but with Rails 4, but
most
of it is unnecessary and is handled automatically unless there’s a twist
I’m not seeing here. serialization is now automatic as is responding
with
an error if the item isn’t found. Unless there’s a unique aspect to
what
you’re doing, you don’t need your own serializer. All you should need
is
the following:

class ItemsController < ApplicationController
respond_to :json

def index
@items = Item.all
respond_with(@items)
end

def show
@item = Item.find(params[:id])
respond_with(@item)
end
end
