uninitialized constant Ruby on rails new controllers

This line in my stands_controller.rb file:

@stand_items = Stand_Item.where("stand_id = " + (params[:id]).to_s)

causes the error:

uninitialized constant StandsController::Stand_Item

But, I have a file named: stand_items_controller.rb with the contents:

class StandItemsController < ApplicationController  
end

I have tried many constant names such as StandItem, Standitem, Stand_item and plurals of all those but no success.

What is the correct constant name? Is there some place where rails stores it?

I have this same concept working elsewhere in the code: I have the line:

  @mark_count = Markstand.where("stand_id = " + (params[:id]).to_s)

directly above the line causing the error, and it gives no error. Markstand is the constant name for the file markstands_controller.rb which has the contents:

class MarkstandsController < ApplicationController
end

EDIT 1 This is how I made the controller:

bin/rails generate controller stand_items

You've generated a controller but you're trying to use a model from within that controller. You need to generate a model for StandItem and then use that from the controller.

bin/rails generate model stand_item ...

See the documentation for the parameters you can pass to setup your model.
