Uninitialized constant Spree::Api::AramexAddressController::AramexAddressValidator

I am facing the following issue:

Why am I am facing the issue mentioned at the top?

maybe you can try this:
namespace :spree do
namespace :api do
resources :aramex_address, only: [] do
get :validate_address_with_aramex
get :fetch_cities_from_aramex_address
end
end
end
words of advice I think it's better if you rename the fetch_cities_from_aramex_address with show method, so it still follow rails convenience

well here is the issue of constant lookup. Your constant that is AramexAddressValidator is missing because of the way you wrote class Spree::Api::AramexAddressController < ApplicationController
So if your module AramexAddressValidator is inside some scope use that scope also while including this module
For Ex. if its inside spree/aramex_address_validator use
include Spree::AramexAddressValidator

ionic cordova encrypt base64 image

Uncaught TypeError: Cannot use 'in' operator to search for 'model' in undefined

i'm learning Backbone.js from the online book 'backbone-fundamentals',
while trying the example i got an error in console related to underscore.js:
Uncaught TypeError: Cannot use 'in' operator to search for 'model' in undefined
i searched for the error on SO what i found as the cause of this error was that i should not pass strings to my model when initializing it. but i didn't.
here is my project, my model:
// models/todo.js
var app = app || {};
app.Todo = Backbone.Model.extend({

where should i look when such an error happens?
thank you for your time...
edit:
the error happens when i load the page without doing anything further.
the order of the files is:
<script src="js/models/todo.js"></script>
<script src="js/collections/todos.js"></script>
<script src="js/views/todos.js"></script>
<script src="js/views/app.js"></script>
<script src="js/routers/router.js"></script>
<script src="js/app.js"></script>
the whole error message:
Uncaught TypeError: Cannot use 'in' operator to search for 'model' in undefined
